Safety Notes

General Power Tool Safety Warnings
WARNING Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire, and/or serious injury.
Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.
Work area safety
Keep the work area clean and well-lit. Cluttered or dark areas invite accidents.
Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks that may ignite dust or fumes.
Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

Electrical safety

Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce the risk of electric shock.
Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges, and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
Do not abuse the cord. Never use the cord for carrying, pulling, or unplugging the power tool. Keep cord away from heat, oil, sharp edges, and moving parts. Damaged or entangled cords increase the risk of electric shock.
▶ When operating a power tool outdoors, use an extension cord suitable for outdoor use. The use of a cord suitable for outdoor use reduces the risk of electric shock. If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. The use of an RCD reduces the risk of electric shock.
Personal safety
Stay alert, watch what you are doing, and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating power tools may result in serious personal injury.
▶ Use personal protective equipment. Always wear eye protection. Protective equipment such as dust masks, non-skid safety shoes, hard hats, or hearing protection used for appropriate conditions will reduce personal injuries.
▶ Prevent unintentional starting. Ensure the switch is in the off-position before connecting to a power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energizing power tools that have the switch on invites accidents.
▶ Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury. Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts.
▶ If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. The use of dust collection can reduce dust-related hazards.
Power tool use and care
▶ Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate at which it was designed. ▶ Do not use the power tool if the switch does not turn on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
▶ Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
▶ Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
▶ Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
▶ Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
▶ Use the power tool, accessories and tool bits, etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.
Service
▶ Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.
Safety Warnings for Routers
▶ Hold power tool by insulated gripping surfaces, because the cutter may contact its own cord. Cutting a “live” wire may make exposed metal parts of the power tool “live” and shock the operator.
▶ Use clamps or another practical way to secure and support the workpiece to a stable platform. Holding the work by your hand or against the body leaves it unstable and may lead to loss of control.
▶ The allowable speed of the router bit must be at least as high as the maximum speed listed on the power tool. Accessories that rotate faster than permitted can be destroyed.
▶ Router bits or other accessories must fit exactly in the tool holder (collet) of your machine. Routing bits that do not fit precisely in the tool holder of the machine rotate irregularly, vibrate heavily, and can lead to loss of control.
▶Apply the machine to the workpiece only when switched on. Otherwise, there is a danger of kickback when the cutting tool jams into the workpiece.
▶ Keep your hands away from the routing area and the router bit. Hold the auxiliary handle or the motor housing with your second hand. When both hands hold the machine, they cannot be injured by the router bit.
▶ Never cut over metal objects, nails, or screws. The router bit can become damaged and lead to increased vibrations.
Use suitable detectors to determine if utility lines are hidden in the work area or call the local utility company for assistance. Contact with electric lines can lead to fire and electric shock. Damaging a gas line can lead to an explosion. Penetrating a water line causes property damage or may cause an electric shock.
▶ Do not use blunt or damaged router bits. Blunt or damaged router bits cause increased friction, can become jammed, and lead to imbalance.
▶ When working with the machine, always hold it firmly with both hands and provide a secure stance. The power tool is guided more securely with both hands.
▶ Secure the workpiece. A workpiece clamped with clamping devices or in a vice is held more secure than by hand.
▶ Always wait until the machine has come to a complete stop before placing it down. The tool insert can jam and lead to loss of control over the power tool.

The vibration emission level given in this information sheet has been measured in accordance with a standardized test given in EN 60745 and may be used to compare one tool with another. It may be used for a preliminary assessment of exposure.
The declared vibration emission level represents the main applications of the tool. However, if the tool is used for different applications, with different accessories, or poorly maintained, the vibration emission may differ. This may significantly increase the exposure level over the total working period.
An estimation of the level of exposure to vibration should also take into account the times when the tool is switched off or when it is running but not actually doing the job. This may significantly reduce the exposure level over the total working period.
Identify additional safety measures to protect the operator from the effects of vibration such as: maintaining the tool and the accessories, keeping hands warm, organize work patterns.

Inserting a Router Bit (see figure D)
▶ It is recommended to wear protective gloves when inserting or replacing router bits.
Depending on the application, router bits are available in the most different designs and qualities.
Router bits made of high-speed steel (HSS) are suitable for the machining of soft materials, e. g. softwood, and plastic.
Carbide tipped router bits (HM) are particularly suitable for hard and abrasive materials, e. g. hardwood and aluminum.
Original router bits from the extensive Bosch accessories program are available at your specialist shop.
Use router bits with a shank diameter of 12 mm as far as this is possible. Only use clean router bits that are in perfect condition.
The router bit can be changed when the routing motor is mounted in the plunge base/non-plunge base. However, it is recommended to change the tool with the routing motor dismounted.
– Remove the routing motor from the plunge base/nonplunge base.
– Press and hold the spindle lock button 27 (1). If required, turn the spindle by hand until the lock engages.
Actuate the spindle lock button 27 only when at a standstill.
– Loosen the tightening nut 17 with the open-end spanner 28 (size 24 mm) by turning in an anticlockwise direction (2 ).
– Insert the router bit into the collet. The shank of the router bit must be immersed at least 20 mm into the collet.
– Tighten the tightening nut 17 with the open-end spanner 28 (size 24 mm) by turning in a clockwise direction. Release the spindle lock button 27.
▶ Do not insert a router bit with a diameter larger than 50 mm when the guide bushing is not mounted. Such router bits do not fit through the base plate.
▶ Do not tighten the tightening nut of the collet without a router bit inserted. Otherwise, the collet can be damaged.
Dust/Chip Extraction
Dust from materials such as lead-containing coatings, some wood types, minerals, and metal can be harmful to one’s health. Touching or breathing in the dust can cause allergic reactions and/or lead to respiratory infections in the user or bystanders.
Certain dust, such as oak or beech dust, are considered carcinogenic, especially in connection with wood-treatment additives (chromate, wood preservative). Materials containing asbestos may only be worked by specialists.
– As far as possible, use a dust extraction system suitable for the material.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the materials to be worked on.
▶ Prevent dust accumulation at the workplace. Dust can easily ignite.
Mounting the Extraction Adapter to the Plunge Base (see figure E) The extraction adapter 30 can be mounted with the hose connection facing toward the front or rear. When the guide-bushing adapter 50 is inserted, it may be required to mount the guide-bushing adapter turned 180°, so that the extraction adapter 30 does not touch the release lever 52. Fasten the extraction adapter 30 with the 2 knurled screws 29 to the base plate 13.
To ensure optimum extraction, the extraction adapter 30 must be cleaned regularly.
Mounting the Extraction Adapter to the Non-plunge Base (see figure F)
The extraction adapter 32 can be mounted with the hose connection facing toward the front or rear. When the guide-bushing adapter 50 is inserted, fasten the extraction adapter 32 with the 2 knurled screws 29 to the base plate 13. For applications without the guide-bushing adapter 50, firstly mount the intermediate ring 33 to the extraction adapter 32, as shown in the figure.
Connecting the Dust Extraction
Insert an extraction hose (Ø 35 mm) 31 (accessory) into the mounted extraction adapter. Connect the extraction hose 31 to a vacuum cleaner (accessory).
The machine can be plugged directly into the receptacle of a Bosch all-purpose vacuum cleaner with remote starting control. The vacuum cleaner starts automatically when the machine is switched on.
The vacuum cleaner must be suitable for the material being worked. When vacuuming dry dust that is especially detrimental to health or carcinogenic, use a special vacuum cleaner.

To start the machine, press the On/Off switch 20 and keep it pressed.
To lock the pressed On/Off switch 20, press the lock-on button 19.
To switch off the machine, release the On/Off switch 20 or when it is locked with the lock-on button 19, briefly press the On/Off switch 20 and then release it.
When not using the power tool, switch it off in order to save energy.

Constant Electronic Control
Constant electronic control holds the speed constant at no load and under load and ensures uniform working performance.
Soft Starting
The electronic soft starting feature limits the torque upon switching on and increases the working life of the motor.
Adjusting the Depth-of-cut
▶ The adjustment of the depth-of-cut may only be carried out when the router is switched off.

Adjusting the Depth-of-cut on the Plunge Base (see figure G)
For coarse adjustment of the depth-of-cut, proceed as follows:
– Place the machine with the router bit mounted on the workpiece to be machined.
– Set the scale for fine adjustment from 6 to “0”.
– Set the turret stop 12 to the lowest setting; the turret stop can be felt to engage.
– Loosen the knurled screw at depth stop 16, so that the depth stop 11 moves freely.
– Press the release lever for plunge-action 7 down and slowly guide the router down until the router bit 18 touches the workpiece surface. Let go of release lever 7 again to lock
this plunging depth.
– Push the depth stop 11 down until it faces against the turret stop 12. Set the slide with the index mark 10 to the “0” position on the scale for depth-of-cut adjustment 9.
– Set the depth stop 11 to the desired routing depth and tighten the knurled screw 16 for the depth stop. Take care not to misadjust the slide with the index mark 10.
– Press the release lever for plunge-action 7 and guide the router to the uppermost position.
The set routing depth is only reached when depth stops 11 touches the turret stop 12 while plunging.
For deep cuts, it is recommended to carry out several cuts, each with little material removal. By using the turret stop 12, the cutting process can be divided into several steps. For this, adjust the desired depth-of-cut to the lowest step of the turret stop and select the higher steps first for the initial cuts. The clearance of the steps is approx. 3.2 mm. 
After a trial cut, the depth-of-cut can be set exactly to the desired measure by turning the adjustment knob 5; turn in a clockwise direction to increase the cutting depth and in an anticlockwise direction to decrease the cutting depth. A scale of 6 can be used for guidance. One full turn corresponds with a setting range of 1.5 mm; a graduation mark on the top edge of the scale 6 corresponds with a 0.1 mm change in the setting range. The maximum setting range is ± 16 mm.

Example: The desired depth-of-cut is to be 10.0 mm; the trial cut resulted in a cutting depth of 9.6 mm.
– Press the release lever for plunge-action 7 and guide the router to the uppermost position.
– Turn adjustment knob 5 by 0.4 mm/4 graduation marks (difference from nominal to the actual value) in a clockwise direction.
– Check the selected depth-of-cut by carrying out another trial cut.

When fine-adjusting the routing depth, take care that the index mark 8 on the side of the plunge base points towards the center imprinted line. This measure ensures that there is sufficient travel in both directions for readjustment of the plunge depth.
When the plunge base 2 is lowered to the maximal plunge depth, cutting deeper by means of the fine adjustment is not possible, as the maximum travel has been utilized. Fine adjustment is also not possible when the depth stops 11 faces against the turret stop 12.
Adjusting the Depth-of-cut on the Non-plunge Base (see figure H)
For adjustment of the depth-of-cut, proceed as follows:
– Open the clamping lever for the non-plunge base 22.
– Coarse pre-adjustment of the routing depth is possible in 3 steps. For this, press clamping lever 25 and slide the routing motor 1 up or down in the non-plunge base 3, until it, with the clamping lever 25 released, is locked in one of the 3 notches 26. The notches each have a clearance of 12.7 mm (0.5 “).
– The adjustment knob for depth-of-cut fine adjustment 24 is used for fine adjustment of the routing depth; turn clockwise to increase the rooting depth, and anticlockwise to decrease the routing depth. The travel on the scale of adjustment knob 24 is indicated in inches and millimeters. The maximum setting range is 41 mm. The scale for depth-of-cut adjustment 34 provides added orientation.
Example: The desired depth-of-cut is to be 10.0 mm; the trial cut resulted in a cutting depth of 9.5 mm.
– Set the scale of the adjustment knob 24 to “0” without changing the setting of the adjustment knob 24 itself. Then set the adjustment knob 24 to the value “0.5” by turning in a clockwise direction.
– Check the selected depth-of-cut by carrying out another trial cut.

Working Advice

The direction of the Feed and Routing Process (see figure I)
▶ The routing process must always be carried out against the rotation direction of the router bit 18 (up-cutting motion). When routing in the direction with the rotation of the router (down-cutting), the machine can break loose, eliminating control by the user.

For routing with the plunge base 2, proceed as follows:
– Adjust the required depth-of-cut; see Section “Adjusting the Depth-of-cut”.
– Place the machine with the router bit mounted on the workpiece to be machined and switch the power tool on.
– Press the release lever for plunge-action 7 down and slowly guide the router down until the set depth of cut is reached. Let go of release lever 7 again to lock this plunging depth.
– Carry out the routing process by applying uniform feed.
– After finishing the routing process, guide the router up to the uppermost position.
– Switch the power tool off.
For routing with the non-plunge base 3, proceed as follows:
Note: Take into consideration that for routing work with the non-plunge base 3, the router bit 18 always protrudes out of the base plate 13. Do not damage the template or the workpiece.
– Adjust the required depth-of-cut; see Section “Adjusting the Depth-of-cut”.
– Switch the machine on and guide it to the location subject to routing.
– Carry out the routing process by applying uniform feed.
– Switch the power tool off. Do not place the power tool down until the router bit has come to a standstill

Routing with Auxiliary Guide (see figure J)
For working large workpieces, e. g., when routing grooves, a board or straight edge can be securely fastened to the workpiece as an auxiliary guide. The multifunction router can be guided alongside the path of this auxiliary guide. When using plunge base 2, guide the guide plate (flattened side) of the multifunction router alongside the auxiliary guide.

Shaping or Molding Applications
For shaping or molding applications without the use of a parallel guide, the router bit must be equipped with a pilot or a ball bearing.
– Guide the switched-on power tool from the side toward the workpiece until the pilot or the ball bearing of the router bit faces against the workpiece edge to be machined.
– Guide the power tool alongside the workpiece edge with both hands, paying attention that the router is positioned rectangular. Too much pressure can damage the edge of the workpiece.
Routing with Parallel Guide (see figure K)
Slide the parallel guide 35 with the guide rods 36 into the base plate 13 and tighten as required with the wing bolts 41. Additionally, the parallel guide can be adjusted lengthwise
with the wing bolts 37 and 38.
Fine adjustment of the length is possible with the fine-adjustment knob 39 after loosening both wing bolts 37. One revolution corresponds with a setting range of 2.0 mm. One  graduation mark on the fine-adjustment knob 39 changes the setting range by 0.1 mm.
The effective contact surface of the parallel guide can be adjusted with the edge guide 40. Guide the switched-on power tool with uniform feed and lateral pressure on the parallel guide alongside the workpiece edge.

Routing with the Router Compass (see figure L)
The router compass/guide-rail adapter 42 can be used for circular routing jobs. Mount the router compass as shown in the figure.
Screw the centering screw 47 into the thread on the router compass. Insert the point of the centering screw into the center of the circular arc to be routed, paying attention that the point of the screw engages into the workpiece surface.
Coarsely adjust the required radius by moving the router compass and tightening the wing bolts 44 and 45.
The length can be fine adjusted with the fine-adjustment knob 46 after loosening the wing bolt 45. One revolution corresponds with a setting range of 2.0 mm. One graduation mark on the fine-adjustment knob 46 changes the setting range by 0.1 mm.
Guide the switched-on power tool over the workpiece with the right handle 4 and the router compass handle 43.
Routing with Guide Rail (see figure M)
Straight routing cuts can be carried out with help of the guide rail 49.
The base spacer 48 must be mounted in order to compensate for the height difference.
Mount the router compass/guide-rail adapter 42 as shown in the figure.
Fasten the guide rail 49 to the workpiece with suitable clamping devices, e.g. screw clamps. Place the machine with the guide-rail adapter 42 mounted onto the guide rail.
Routing with Guide Bushing (see figures N–Q)
The guide bushing 53 enables template and pattern routing on workpieces.
In order to use guide bushing 53, the guide bushing adapter 50 must be inserted into guide plate 14 first.
Place the guide bushing adapter 50 from above onto the guide plate 14 and tighten it firmly with the 2 fastening screws 51. Pay attention that the release lever for the guide bushing adapter 52 is freely movable.
Choose a suitable guide bushing, depending on the thickness of the template or the pattern. Because of the projecting height of the guide bushing, the template must have a  minimum thickness of 8 mm.
Actuate the release lever 52 and insert the guide bushing 53 from below into the guide bushing adapter 50. Ensure that the encoding keys clearly engage in the grooves of the guide bushing.
Check the clearance from the router bit center and guide bushing edge, see section “Centring the Base Plate”.
Select a router bit with a diameter smaller than the interior diameter of the guide bushing.
For routing with the guide bushing 53 proceed as follows:
– Note: Take into consideration that for routing work with the non-plunge base 3, the router bit 18 always protrudes out of the base plate 13. Do not damage the template or the workpiece.
– Guide the switched-on power tool with the guide bushing toward the template.
– When using the plunge base 2: Press the release lever for plunge-action 7 down and slowly guide the router down until the set depth-of-cut is reached. Let go of release lever  7 again to lock this plunging depth.
– Guide the switched-on power tool with the protruding guide bushing alongside the template applying lateral pressure
Centering the Base Plate (see figure R)
To ensure that the distance from the router bit center and guide bushing edge is uniform, the guide bushing and the guide plate can be adjusted to each other, if required.
– When using the plunge base 2: Press the release lever for plunge-action 7 down and guide the router toward the base plate to the stop. Let go of release lever 7 again to lock this plunging depth.
– Loosen fastening screws 54 approx. 2 turns, so that guide plate 14 can move freely.
– Insert the centering pin 55 into the tool holder as shown in the figure. Hand-tighten the tightening nut so that the centering pin can still be moved freely.
– Align the centering pin 55 and the guide bushing 53 to each other by slightly moving the guide plate 14.
– Retighten the fastening screws 54 again.
– Remove the centering pin 55 from the tool holder.
– When using the plunge base 2: Press the release lever for plunge-action 7 and guide the router back to the uppermost position.
Operation with Router Table (see figure S)
The non-plunge base 3 can be used with a suitable router table. To install the router, remove the guide plate 14 and fasten the non-plunge base 3 to the router table with the fastening screws 56.
For mounting the non-plunge base, please observe the operating instructions of your router table. If necessary, matching holes must be drilled into the router table in order to mount the non-plunge base. For fine adjustment of the depth-of-cut, it is best to use extension 58 or the specialty Allen key 57.
Routing with Extraction Hood (see figures T–U)
For routing edges, the extraction hood 59 can additionally be used.
– Fasten the extraction hood 59 with the 2 fastening screws 60 to the base plate 13. The extraction hood 59 can be fastened in 3 different positions, as shown in the figure.
– Remove the extraction hood again for routing smooth plane surfaces

Maintenance and Service

Maintenance and Cleaning
▶ Before any work on the machine itself, pull the mains plug.
▶ For safe and proper working, always keep the machine and ventilation slots clean.
▶ In extreme conditions, always use dust extraction as far as possible. Blow out ventilation slots frequently and install a residual current device (RCD). When working metals, conductive dust can settle in the interior of the power tool. The total insulation of the power tool can be impaired.
If the replacement of the supply cord is necessary, this has to be done by Bosch or an authorized Bosch service agent in order to avoid a safety hazard.
If the machine should fail despite the care taken in manufacturing and testing procedures, repair should be carried out by an after-sales service center for Bosch power tools.
In all correspondence and spare parts orders, please always include the 10-digit article number given on the type plate of the machine.
