BOSCH PST Universal Jigsaw

General Power Tool Safety Warnings

  • 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 energising 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 jewellery.
  • 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 extraction and collection facilities, ensure these are connected and properly used. 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 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.

Battery tool use and care

  •  Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.
  •  Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
  •  When battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects, that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.
  •  Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.

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  Jigsaw

  • Hold power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring or its own cord.
  • Cutting accessory contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.
  •  Keep hands away from the sawing range. Do not reach under the workpiece. Contact with the saw blade can lead to injuries.
  • Apply the machine to the workpiece only when switched on. Otherwise there is danger of kickback when the cutting tool jams in the workpiece.
  • Pay attention that the base plate 6 rests securely on the material while sawing. A jammed saw blade can break or lead to kickback.
  • When the cut is completed, switch off the machine and then pull the saw blade out of the cut only after it has come to a standstill. In this manner you can avoid kickback and can place down the machine securely.
  • Use only undamaged saw blades that are in perfect condition. Bent or dull saw blades can break, negatively influence the cut, or lead to kickback.
  • Do not brake the saw blade to a stop by applying side pressure after switching off. The saw blade can be damaged, break or cause kickback.
  • 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.
  • 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.
  • 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 30mA or less.

Technical Data

Noise/Vibration Information Sound emission values determined according to EN 60745-2-11. Typically the A-weighted noise levels of the product are: Sound pressure level 85 dB(A); Sound power level 96 dB(A). Uncertainty K =3 dB.

Wear hearing protection!

Vibration total values ah (triax vector sum) and uncertainty K determined according to EN 60745: Cutting board: ah=13m/s2, K=3m/s2, Cutting sheet metal: ah=7m/s2, K=1.5m/s2. The vibration level given in this information sheet has been measured in accordance with a standardised 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 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 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: maintain the tool and the accessories, keep the hands warm, organisation of work patterns.

Assembly

  •  Before any work on the machine itself, pull the mains plug. Replacing/Inserting the Saw Blade
  •  When mounting the saw blade, wear protective gloves. Danger of injury when touching the saw blade.

Selecting a Saw Blade

An overview of recommended saw blades can be found at the end of these instructions. Use only T-shank saw blades or saw blades with 1/4″ universal shank (U-shank). The saw blade should not be longer than required for the intended cut. Use a thin saw blade for narrow curve cuts.

Inserting the Saw Blade  

Clean the shank of the saw blade before inserting it. An unclean shank cannot be fastened securely. If required, remove the dust cover 9 (see “Dust Cover”). Push the saw blade holder 13 upward in the direction of the arrow. Insert the saw blade 15 (teeth in cutting direction) to the stop into the saw blade holder. While inserting the saw blade, pay attention that the back of the saw blade is positioned in the groove of the guide roller 14.

Check the tight seating of the saw blade.

A loose saw blade can fall out and lead to injuries.

Removing the Saw Blade 

Push the saw blade holder 13 upward in the direction of the arrow and remove the saw blade 15. If the saw blade is wedged or jammed when removing, set adjusting lever 7 to maximum orbital action and press the saw blade holder 13 lightly toward the front (max. 2 mm). Saw Blade Storage   (PST Universal+) Up to six saw blades with lengths to 110 mm can be stored in the saw blade storage 5. Insert the saw blades with the T-shank into the recess of the saw blade storage intended for this. Up to three saw blades can be placed on top of each other. Shut the saw blade storage and slide it to the stop into the opening of the base plate 6.

Splinter Guard  

The splinter guard 16 (accessory) can prevent fraying of the surface while sawing wood. The splinter guard can only be used for certain saw blade types and only for cutting angles of 0°. When sawing with the splinter guard, the base plate 6 must not be moved back for cuts that are close to the edge. Press the splinter guard 16 from the bottom into the base plate 6

“Cut Control” (PST Universal+)

“Cut Control” enables precise guiding of the power tool along a cutting line marked on the workpiece. The “Cut Control” kit includes the viewing window 11 with cutting marks and the base 10 for attachment to the power tool.

Attaching “Cut Control” to the Base Plate 

Clamp the “Cut Control viewing window ” 11 into the holders of Cut Control base 10. Then, lightly press the base together and allow it to engage into the accessory holder 17 of the base plate.

Dust/Chip Extraction

  •  Dusts 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 dusts can cause allergic reactions and/or lead to respiratory infections of the user or bystanders. Certain dusts, such as oak or beech dust, are considered as 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.

Prevent dust accumulation at the workplace. Dusts can easily ignite.

Dust Cover (see figures E–F) (PST Universal+)

Mount the dust cover 9 before connecting the machine to the dust extraction. Mount the dust cover 9 onto the machine in such a manner that the centre holder engages on the contact protector 18 and the two outer holders engage in the openings on the casing. Remove the dust cover 9 for applications without dust extraction as well as when performing mitre cuts. For this, push the dust cover together at the two outer holders and pull it off toward the front.

Connecting the Dust Extraction

Place a vacuum hose 3 (accessory) onto the vacuum connection 4. Connect the vacuum hose 3 with a vacuum cleaner (accessory). An overview for the connection of various vacuum cleaners can be found at the end of these instructions. Switch the saw dust blower off when a dust extraction system is connected (see “Sawdust Blower Device”).

Operation

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

Orbital Action Settings

  • The four orbital action settings allow for optimal adaptation of cutting speed, cutting capacity and cutting pattern to the material being sawed.
  • The orbital action can be adjusted with the adjusting lever 7, even during operation.
  • The optimal orbital action setting for the respective application can be determined through practical testing. The following recommendations apply:
  •  Select a lower orbital action setting (or switch it off) for a finer and cleaner cutting edge.
  •  For thin materials such as sheet metal, switch the orbital action off.
  •  For hard materials such as steel, work with low orbital action.
  •  For soft materials and when sawing in the direction of the grain, work with maximum orbital action.

Adjusting the Cutting Angle 

The base plate 6 can be swivelled by 45° to the left or right for mitre cuts. The dust cover 9 and the splinter guard 16 cannot be used when performing mitre cuts. If required, remove the dust cover 9 (see “Dust Cover”, page 15) and take off the splinter guard 16 (see “Splinter Guard”, page 15). Pull the saw blade storage 5 out of the base plate 6 (PST Universal+). Loosen the screw 19 and lightly slide the base plate 6 toward the vacuum connection 4. For adjustment of precise mitre angles, the base plate has adjustment notches on the left and right at 0°, 22.5° and 45°. Swivel the base plate 6 to the desired position according to the scale 20. Other mitre angles can be adjusted using a protractor. Afterwards, push the base plate 6 to the stop in the direction of the saw blade 15. Tighten the screw 19 again.

Cut Control for Bevel Cuts (PST Universal+)

For cutting-line control of bevel cuts, the “Cut Control” viewing window 11 has a mark 21 for 0° right-angle cuts and a mark 22 each for the left- or rightward sloping 45° bevel cut according to scale 20. The cutting mark for bevel cuts between 0° and 45° results proportionally. It can additionally be drawn on the “Cut Control” viewing window 11 with a non-permanent marker, and easily be removed again. For accurate working, it is best to carry out a test cut.

Offsetting the Base Plate

For sawing close to edges, the base plate 6 can be offset to the rear. Loosen the screw 19 and slide the base plate 6 toward the vacuum connection 4 to the stop. Tighten the screw 19 again. Sawing with the base plate 6 offset is possible only at a 0° bevel angle. Additionally, “Cut Control” may not be used together with the base 10 as well as the splinter guard 16.

Sawdust Blower Device

With the air jet of the sawdust blower device 8, the cutting line can be kept free of dust and chips. Switching on the sawdust blower device: For cuts in materials with high removal rate, such as in wood, plastic, etc., push the switch 8 toward the vacuum connection. Switching off the sawdust blower device: For cuts in metal and when a dust extraction system is connected, push the switch 8 toward the saw blade.

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 start the machine, press the On/Off switch 2.
  • To lock the On/Off switch 2, keep it depressed and push the lock-on button 1 to the right or left
  • To switch off the machine, release the On/Off switch 2. When the On/Off switch 2 is locked, press it first and then release it.
  • To save energy, only switch the power tool on when using it.

Controlling the Stroke Rate

  • Increasing or reducing the pressure on the On/Off switch 2 enables stepless stroke-rate control of the switched-on machine.
  • When the On/Off switch 2 is locked, it is not possible to reduce the stroke rate.
  • The required stroke rate is dependent on the material and the working conditions and can be determined by a practical trial. Reducing the stroke rate is recommended when the saw blade engages in the material as well as when sawing plastic and aluminium.
  • After longer periods of work at low stroke rate, the machine can heat up considerably. Remove the saw blade from the machine and allow the machine to cool down by running it for approx. 3 minutes at maximum stroke rate.

Working Advice

  •  Before any work on the machine itself, pull the mains plug.
  •  When working small or thin workpieces, always use a stable support or a saw station (Bosch PLS 300). Saw with moderate pressure in order to achieve optimal and precise cutting results.
    For long and straight cuts in thick wood (>40 mm), the cutting line can become inaccurate. In this case, using a Bosch circular saw is recommended to achieve accurate cuts. Plunge Cutting (see figure H)
  •  Plunge cuts may only be applied to soft materials, such as wood, gypsum plaster boards, etc.! Use only short saw blades for plunge cutting. Plunge cutting is possible only with the mitre angle set at 0°. Place the machine with the front edge of the base plate 6 on to the workpiece without the saw blade 15 touching the workpiece and switch on. For machines with stroke rate control, select the maximum stroke rate. Firmly hold the machine against the workpiece and by tilting the machine, slowly plunge the saw blade into the workpiece. When the base plate 6 fully lays on the workpiece, continue sawing along the desired cutting line.

Coolant/Lubricant
When sawing metal, coolant/lubricant should be applied alongside cutting line because of the material heating up.

Maintenance and Cleaning

  •  For safe and proper working, always keep the machine and ventilation slots clean.
  • Clean the application tool, the tool holder, the power tool’s ventilations slots, and the battery’s ventilation slots each time after using.
