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 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 which may ignite the 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 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. 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. 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 mask, non-skid safety shoes, hard hat, 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 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 jewel-lery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
    • If devices are provided for the connection of dust ex-traction and collection facilities, ensure these are con-nected and properly used. Use of dust collection can re-duce 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 for which it was designed.
    •  Do not use the power tool if the switch does not turn it 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 per-son using only identical replacement parts. This will en-sure that the safety of the power tool is maintained.
  • Planer Safety Rules
    •  Wait for the cutter to stop before setting the tool down. An exposed rotating cutter may engage the surface leading to possible loss of control and serious injury.
    • Hold the power tool by insulated gripping surfaces on-ly, because the cutter may contact its own cord. Cutting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.
    • Use clamps or another practical way to secure and sup-port 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.
    • 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 explosion. Penetrating a water line causes property damage or may cause an electric shock.
    •  Do not reach into the chip ejector with your hands. They could be injured by rotating parts.
    •  Apply the machine to the workpiece only when switched on. Otherwise there is danger of kickback when the cutting tool jams in the workpiece.
    •  When working, always hold the planer in such a manner that the planer base plate faces flat on the workpiece. Otherwise the planer can become wedged and lead to injuries.
    • Never plane over metal objects, nails or screws. The planer blade and the blade shaft can become damaged and lead to increased vibrations.
    • Products sold in GB only: Your product is fitted with a BS 1363/A approved electric plug with internal fuse
      (ASTA approved to BS 1362). If the plug is not suitable for your socket outlets, it should be cut off and an appropriate plug fitted in its place by an authorised customer service agent. The replacement plug should have the same fuse rating as the original plug. The severed plug must be disposed of to avoid a possible shock hazard and should never be inserted into a mains socket elsewhere.
      Products sold in AUS and NZ only: Use a residual current device (RCD) with a rated residual current of 30 mA or less.

Technical Data

Noise/Vibration Information

Sound emission values determined according to
EN 60745-2-14.
Typically the A-weighted noise levels of the product are: Sound pressure level 86 dB(A); Sound power level 97 dB(A). Uncertainty K =3 dB.

Wear hearing protection!
Vibration total values ah (triax vector sum) and uncertainty K determined according to EN 60745-2-14:
ah=5.5 m/s2, K=1.5 m/s2.
The vibration 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 ap-plications of the tool. However if the tool is used for different applications, with different accessories or insertion tools or is 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 sig-nificantly reduce the exposure level over the total working period.
Identify additional safety measures to protect the operator from the effects of vibration such as: maintain the tool and the accessories, keep the hands warm, organization of work pat-terns.

Assembly

  • Before any work on the machine itself, pull the mains  plug. 

Planer Blade Selection
The power tool can be fitted with different planer blade types.
By using conversion kits (accessory), either planer blade type (HSS or TC carbide blades) can be used, depending on the standard equipment of the power tool. When replacing planer blades, always replace both blades; otherwise an imbalance can generate vibrations, which can reduce the service life of the power tool.
Changing HSS Planer Blade

  • Be cautious when replacing the planer blades. Do not grasp the planer blades by the cutting edges. Possible danger of injury due to the sharp cutting edges of the planer blades.
  • Disassembling the Planer Blade(s) (see figures A – C)
    • To reverse the planer blades, rotate the blade drum 13 un-til the clamping jaw 12 is parallel to the planer base plate 8.
    • Unscrew the 3 fastening screws 11 with the Torx key 10 and remove the clamping jaw 12.
    • Slide the planer-blade retainer 16 together with the planer blade 15 out of the guide groove 14 of the blade drum 13.
    • Turn the blade drum by 180° and disassemble the 2nd planer blade.

Note: Before replacing or resharpening the planer blades, re-move the HSS planer-blade retainer 16 by loosening the fastening screws 17.

Resharpening HSS Planer Blades (see figure D)

Worn or dull HSS planer blades can be resharpened with the sharpening device 18 (accessory) and a commercially available whetstone.
Insert both planer blades into the sharpening device and clamp them by tightening the wing bolt. Make sure that both planer blades are completely inserted to the stop.
Move the sharpening device with the inserted planer blades uniformly and with light pressure across the whetstone.
Note: Never regrind the planer blades by more than 6 mm, based on a minimum width of 23 mm. Thereafter, both planer blades must be replaced.

Assembling the Planer Blade(s) (see figures E–F)

Before reinserting new or resharpened planer blades, clean the blade drum 13 and the planer blades 15, if required, as well as the HSS planer-blade retainer 16. Clean heavily gummed planer blades with spirits or petroleum.
Note: Before assembling new or resharpened planer blades, their correct height setting must be adjusted first.
The setting gauge 19 (accessory) is used for adjusting the height of the planer blades. Place the planer blade 15 and the blade retainer 16 on the setting gauge. Make sure that the blade retainer 16 engages in the groove intended for this purpose. Press the planer blade 15 against the stop and lock the blade retainer 16 in this position with the fastening screws 17. This will automatically adjust the correct height.
Each planer blade must be assembled and aligned centered to the planer base plate 8. Afterwards, tighten the three fas-tening screws 11 with the Torx key 10, ensuring the correct tightening sequence () on the clamping jaw 12.
Note: Before starting operation, check the fastening screws 11 for tight seating. Rotate the blade head 13 manually and ensure that the planer blades do not graze.

Replacing Carbide Blades (TC)
  • Be cautious when replacing the planer blades. Do not grasp the planer blades by the cutting edges. Possible danger of injury due to the sharp cutting edges of the planer blades.
  • Use only original Bosch carbide blades (TC).
  • The carbide planer blades (TC) have two cutting edges, which can be reversed. When both cutting edges are dull, the planer blades 20 must be replaced. Carbide blades (TC) may not be resharpened.
Disassembling the Planer Blade(s) (see figures G – H)
  • To reverse or replace the planer blades, rotate the blade drum 13 until the clamping jaw 12 is parallel to the planer base plate 8.
  •  Loosen the three fastening screws 11 with the Torx key 10 by approx. 1 – 2 turns. The clamping jaw 12 does not have to be removed.
  • Rotate the blade drum a little and push the planer blade 20 sidewards out of the blade drum 13 with a piece of wood.
  •  Turn the blade drum by 180° and disassemble the 2nd planer blade.
Assembling the Planer Blade(s) (see figures I – J)

The guide groove of the planer blade always ensures continuous height adjustment when replacing or reversing it.
If required, clean the blade seat in the blade drum 13 and the planer blade 20.
When assembling the planer blade, ensure that it is seated properly in the blade holder of the blade drum 13.
Each planer blade must be assembled and aligned centered to the planer base plate 8. Afterwards, tighten the three fastening screws 11 with the Torx key 10, ensuring the correct tightening sequence on the clamping jaw 12.
Note: Before starting operation, check the fastening screws 11 for tight seating. Rotate the blade head 13 manually and ensure that the planer blades do not graze.

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 of the user or bystanders. Certain dust, such as oak or beech dust, is considered carcinogenic, especially in connection with wood-treatment additives (chromate, wood preservative). Materials con-taining 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.
      Clean the chip ejector 3 regularly. Clean a clogged chip ejec-tor using a suitable tool, e. g. a piece of wood, compressed air, etc.
  • Do not reach into the chip ejector with your hands. They could be injured by rotating parts.

To ensure optimum extraction of dust/chips, always work with external dust extraction or a chip/dust bag.

Operation

Operating Modes

Adjusting the Planning Depth
With the adjustment knob 2, the planning depth can be adjusted variably from 0–2.6 mm using the planning depth scale 1 (scale graduation = 0.1 mm).
Park Rest (see figure N)
The park rest 29 allows the machine to be set down directly after operation, without danger of damaging the working sur-face or the planer blade. While planning, the park rest 29 is tilted upwards thus enabling full contact of the rear part of the planer base plate 8.

Starting Operation
  • Observe correct mains voltage! The voltage of the power source must agree with the voltage specified on the nameplate of the machine. Power tools marked with 230 V can also be operated with 220 V.

Switching On and Off
To save energy, only switch the power tool on when using it.
To start the machine, press the On/Off switch 5 and keep it pressed.
To lock the pressed On/Off switch 5, press the lock-on button 4.
To switch off the machine, release the On/Off switch 5 or when it is locked with the lock-on button 4, briefly press the On/Off switch 5 and then release it.

Working Advice
  • Before any work on the machine itself, pull the mains plug.

Planning  (see figure N)
Set the required planning depth and place the front part of the planer base plate 8 against the workpiece.

  • Apply the machine to the workpiece only when switched on. Otherwise there is danger of kickback when the cutting tool jams in the workpiece. Switch the machine on and guide the machine with even feed over the surface to be planed.
  • To achieve high-grade surfaces, work only with low feed and apply pressure on the centre of the planer base plate.
  • When machining hard materials (e.g. hardwood) as well as when utilizing the maximum planer width, set only low planning depths and reduce planer feed, as required.
  • Excessive feed reduces the surface quality and can lead to rapid clogging of the chip ejector.
  • Only sharp blades achieve good cutting capacity and give the machine longer life.
    The integrated park rest 29 also allows for continued planning at any given location on the workpiece after an interruption:
    • With the park rest folded down, place the machine on the location of the workpiece where the planning is to be continued.
    • Switch on the machine.
      Apply the supporting pressure onto the front part of the planer base plate and slowly push the machine forward . This tilts the park rest upward () so that the rear part of the planer base plate faces on the workpiece again.
    • Guide the machine over the surface to be planed with even feed.
Beveling Edges (see figure O)

The V-grooves in the front planer base plate allow quick and easy beveling of workpiece edges. Depending on required bevel width, use the corresponding V-groove. For this, place the planer with the V-groove onto the edge of the workpiece and guide it along the edge.

Planning with Parallel/Beveling Guide (see figures K – M)

Mount the parallel guide 21 or beveling guide 25 to the ma-chine using the corresponding fastening bolt 24. Depending on the application, mount the rebating depth stop 28 with fastening bolt 27 to the machine.
Loosen the locking nut 23 and adjust the requested rebating width on the scale 22. Tighten the locking nut 23 again.
Adjust the requested rebating depth accordingly with the rebating depth stop 28.
Carry out the planning procedure several times until the re-quested rebating depth is reached. Guide the planer applying sideward supporting pressure.

Beveling with the Beveling Guide

When beveling rebates and surfaces, adjust the required slope angle with the angle adjustment 26.

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.

Ensure easy operation of the park rest 29 and clean it regular-ly.
When the carbon brushes wear below acceptable service tolerances, the machine will automatically cut out. The machine must be sent to customer service for maintenance (for ad-dress, see the “After-sales Service and Application Service” section).
If the replacement of the supply cord is necessary, this has to be done by Bosch or an authorized Bosch service agent in or-der to avoid a safety hazard.

Replacing the Drive Belt (see figures P – Q)

Unscrew screw 6 and take off the belt cover 7. Remove the worn drive belt 30.
Before assembling a new drive belt 30, clean both pulleys 31 and 32.
Place the new drive belt 30 on the small pulley 32 first and then work the drive belt 30 onto the large pulley 31 by hand while rotating it.
Make sure that the drive belt 30 runs exactly in the longitudinal grooves of the pulleys 31 and 32.
Reattach the belt cover 7 and tighten with the screw 6.
