Safety Instructions

General Power Tool Safety Warnings

WARNING Read all safety warnings, instruc-tions, illustrations and specifications provided with this power tool. Failure to follow all in- structions listed below 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 (cord-less) 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 sur-faces, such as pipes, radiators, ranges and refrigerat-ors. 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 elec-tric shock.
• Do not abuse the cord. Never use the cord for carry-ing, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
• When operating a power tool outdoors, use an exten-sion cord suitable for outdoor use. Use of a cord suit-able for outdoor use reduces the risk of electric shock.
• If operating a power tool in a damp location is un-avoidable, use a residual current device (RCD) protec-ted 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 per-sonal injury.
• Use personal protective equipment. Always wear eye protection. Protective equipment such as a dust mask, non-skid safety shoes, hard hat or hearing protection used for appropriate conditions will reduce personal in-juries.
• 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 en-ergising power tools that have the switch on invites acci-dents.
• 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 in-jury.
• 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 jew-ellery. Keep your hair and clothing 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.
• Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe in-jury within a fraction of a second.

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 de-signed.
• 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 re-move the battery pack, if detachable, from the power tool before making any adjustments, changing ac-cessories, 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 and accessories. Check for mis-alignment 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 main-tained 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 ac-count the working conditions and the work to be per-formed. Use of the power tool for operations different from those intended could result in a hazardous situation.
• Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.

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 Sander

• Only use the power tool for dry sanding. Water entering a power tool will increase the risk of electric shock.
• Ensure that no persons are at risk due to flying sparks. Remove combustible materials from the surrounding area. Flying sparks are created when sanding metals.
• Warning: Danger of fire! Avoid overheating the work-piece and the sander. Always empty the dust collector before taking a break from work. Sanding dust in the dust bag, microfilter, paper bag (or in the filter bag or va-cuum cleaner filter) can spontaneously combust under certain conditions, for example if flying sparks are cre-ated when sanding metals. This risk is increased if the sanding dust is mixed with paint or polyurethane residue or with other chemical substances and if the workpiece is hot as a result of prolonged work.
• Clean the air vents on your power tool regularly. The motor’s fan will draw the dust inside the housing and ex-cessive accumulation of powdered metal may cause elec-trical hazards.
• Hold the power tool firmly with both hands and make sure you have a stable footing. The power tool can be more securely guided with both hands.
• Always wait until the power tool has come to a com-plete stop before placing it down.
• Secure the workpiece. A workpiece clamped with clamping devices or in a vice is held more secure than by hand.

Technical Data

The specifications apply to a rated voltage [U] of 230 V. These specifications may vary at different voltages and in country-specific models.

Noise/Vibration Information

Noise emission values determined according to EN 62841-2-4.
Typically, the A-weighted noise level of the power tool is:
Sound pressure level 81 dB(A); sound power level 92 dB(A). Uncertainty K = 3 dB.

Wear hearing protection!
Vibration total values ah (triax vector sum) and uncertainty K
determined according to EN 62841-2-4: ah < 2.5 m/s2, K = 1.5 m/s2,
The vibration level and noise emission value given in these instructions have been measured in accordance with a standardised measuring procedure and may be used to compare power tools. They may also be used for a preliminary estimation of vibration and noise emissions.
The stated vibration level and noise emission value represent the main applications of the power tool. However, if the power tool is used for other applications, with different application tools or is poorly maintained, the vibration level and noise emission value may differ. This may significantly increase the vibration and noise emissions over the total working period. To estimate vibration and noise emissions accurately, the times when the tool is switched off or when it is running but not actually being used should also be taken into account.
This may significantly reduce vibration and noise emissions over the total working period.
Implement additional safety measures to protect the operator from the effects of vibration, such as servicing the power tool and application tools, keeping their hands warm, and organising workflows correctly.

Assembly

• Pull the plug out of the socket before carrying out any work on the power tool.

Changing the Sanding Sheet

• To remove the sanding sheet (10), lift it from the side and pull it from the sanding pad (8).
• Remove dirt and dust from the sanding pad (8), e.g. with a paintbrush, before attaching a new sanding sheet.
• The surface of the sanding pad (8) is fitted with a hook-andloop fastening, allowing sanding sheets with a hook-and-loop backing to be secured quickly and easily.
• Press the sanding sheet (10) firmly onto the underside of the sanding pad (8).
• To ensure optimum dust extraction, make sure that the punched holes in the sanding sheet (10) are aligned with the drilled holes in the sanding pad (8).

Selection of the Sanding Plate
The power tool can be fitted with sanding pads of various hardnesses, depending on the application:

• Extra soft sanding pad: Suitable for polishing and sensitive sanding even on curved surfaces
• Soft sanding pad: Suitable for all sanding work, universal application
• Hard sanding pad: Suitable for heavy sanding on flat surfaces

Changing the Sanding Pad

• Note: Replace damaged sanding pads (8) immediately.
• Remove the sanding sheet or polishing tool. Unscrew the screw (11) completely and remove the sanding pad (8). At-tach the new sanding pad (8) and retighten the screw so that it is finger-tight.
• Note: Pads with diameters of 150 mm and 125 mm have dif-ferent carriers. The pads can only be fitted to the right power tool.
• Note: When attaching the sanding pad, make sure that the teeth of the catch mate with the recesses in the sanding pad.
• Note: Damaged sanding pads must only be replaced by an after-sales service centre authorised to work with Bosch power tools.

Dust/chip extraction
The dust from materials such as lead paint, some types of wood, minerals and metal can be harmful to human health. Touching or breathing in this dust can trigger allergic reac-tions and/or cause respiratory illnesses in the user or in people in the near vicinity.
Certain dusts, such as oak or beech dust, are classified as carcinogenic, especially in conjunction with wood treatment additives (chromate, wood preservative). Materials contain-ing asbestos may only be machined by specialists.

• Use a dust extraction system that is suitable for the ma-terial wherever possible.
• Provide good ventilation at the workplace.
• It is advisable to wear a P2 filter class breathing mask. The regulations on the material being machined that apply in the country of use must be observed.
• Avoid dust accumulation at the workplace. Dust can easily ignite.

Self-generated dust extraction with dust box (see figures C–G) Slide the dust box (7) onto the extraction outlet (12). Turn the dust box in such a manner that its recesses face against the tips on the extraction outlet and the dust box can be felt to engage.
You can easily check the filling level of the dust box (7) through the transparent container.
To empty the dust box (7), rotate slightly and pull it back.
Unscrew the filter element (6) and pull it out of the dust box (7). Empty the dust box.
Gently tap the filter element (6) against a solid surface to loosen the dust. Use a soft brush to clean the flaps of the fil-ter element (6).
Note: In order to ensure optimum dust extraction, empty the dust box (7) in good time and clean the filter element (6) regularly.
When working on vertical surfaces, hold the power tool with the dust box (7) facing downwards.

External dust extraction (see figure H)
Fit a dust extraction hose (13) onto the extraction outlet (12). Mount the vacuum hose onto the extraction outlet (as shown in the figure) in such a manner that the lateral open-ings on the extraction outlet remain free. This prevents the power tool from adhering to the workpiece during sanding and the surface quality of the workpiece from being im-paired.
Connect the dust extraction hose (13) to an extractor (ac-cessory). You will find an overview of connecting to various dust extractors at the end of these operating instructions.
The dust extractor must be suitable for the material being worked.
When extracting dry dust that is especially detrimental to health or carcinogenic, use a special dust extractor.
When working on vertical surfaces, hold the power tool with the dust extraction hose facing downwards.

Auxiliary Handle
The auxiliary handle (1) enables comfortable handling and optimum power distribution, with a high sanding removal rate in particular.
Use the screw (2) to secure the auxiliary handle (1) on the housing.

Operation

Starting Operation

• Pay attention to the mains voltage. The voltage of thepower source must match the voltage specified on therating plate of the power tool. Power tools markedwith 230 V can also be operated with 220 V.
• Products that are only sold in AUS and NZ: Use a resid-ual current device (RCD) with a nominal residual currentof 30 mA or less.

Switching on/off

• Make sure that you are able to press the On/Off switchwithout releasing the handle.
• To switch on the power tool, press the on/off switch (4).
• To lock the on/off switch (4), press and hold it while alsopushing the lock-on button (5).
• To switch off the power tool, release the on/off switch (4).If the on/off switch (4) is locked, press the switch first andthen release it.

Preselecting the orbital stroke rate
You can even preselect the orbital stroke rate during opera-tion using the necessary orbital stroke rate preselectionthumbwheel (3).

• 1–2 Low orbital stroke rate
• 3–4 Medium orbital stroke rate
• 5–6 High orbital stroke rate

The required orbital stroke rate is dependent on the materialand the work conditions and can be determined using prac-tical tests.
After working at a low orbital stoke rate for an extendedperiod, you should operate the power tool at the maximumorbital stroke rate for approximately three minutes withoutload to cool it down.

Sanding Plate Brake
An integrated sanding pad brake reduces the orbital strokerate when running without load to prevent scoring when thepower tool is placed on the workpiece.
If the no-load orbital stroke rate constantly increases overtime, this means that the sanding pad is damaged and mustbe replaced, or that the sanding pad brake is worn. A wornsanding pad brake must be replaced by an after-sales ser- vice centre authorised to work with Bosch power tools.

Working Advice

• Pull the plug out of the socket before carrying out anywork on the power tool.
• Always wait until the power tool has come to a com-plete stop before placing it down.
• This power tool is not suitable for bench-mounted use.It must not be clamped into a vice or fastened to a work-bench, for example.

Sanding Surfaces

• Switch the power tool on, place the entire sanding surfaceagainst the surface of the workpiece and apply moderatepressure as you move the sander over the workpiece.
• The material removal rate and sanding result are primarilydetermined by the choice of sanding sheet, the preselectedorbital stroke rate level and the contact pressure.
• Only immaculate sanding sheets achieve good sanding per-formance and make the power tool last longer.
• Be sure to apply consistent contact pressure in order to in-crease the lifetime of the sanding sheets.
• Excessively increasing the contact pressure will not lead toincreased sanding performance, rather it will cause moresevere wear of the power tool and of the sanding sheet.
• Do not use a sanding sheet for other materials after it hasbeen used to work on metal.
• Use only original Bosch-sanding accessories.

Rough Sanding
Attach a coarse grit sanding sheet.
Apply only light pressure to the power tool so that it runs at ahigher orbital stroke rate and a higher material removal rateis achieved.

Fine Sanding
Attach a fine grit sanding sheet.
You can reduce the sanding plate orbital stroke rate bylightly varying the contact pressure or changing the orbitalstroke rate level; the random orbit motion will be retained.
Move the power tool with moderate pressure flat on theworkpiece in a circular motion or alternately along andacross it. Do not tilt the power tool in order to avoid sandingthrough the workpiece, e.g. veneers.
Switch the power tool off after completing operation.

Polishing
For polishing weathered lacquers and redressing scratches(e.g. acrylic glass), the power tool can be fitted with an ap-propriate polishing tool, e.g. lambswool bonnet, polishingfelt or polishing sponge (accessory). Select a low orbital stroke rate (level 1–2) when polishing inorder to avoid heating up the surface excessively.
Apply the polish to an area slightly smaller than the areawhich you intend to polish. Using the appropriate polishingtool, work in the polish with either linear or circular move-ments and with moderate pressure.
Do not allow the polish to dry out on the surface; this maydamage the surface. Do not expose the surface which you in-tend to polish to direct sunlight.
Clean the polishing tool regularly to ensure good polishingresults. Wash the polishing tools with mild detergent andwarm water; do not use thinning agents.

Application Table
The information in the table below is the recommended val-ues.
The best method for determining the best combination whilesanding or polishing is practical experimentation.
