General Power Tool Safety Warnings
WARNING
Read all safety warnings and all instructions provided with this power tool. 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 or 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. 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 usury
• 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 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 the 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 dothkig or Jew­ Keep your hair, clothing, and gloves away from moving parts. Loose clothes. jewelry or long hair can be caught in rallying 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 duce dust. related hazards.

• 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 workpiece 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 vacuum cleaner filter) can spontaneously combust under certain conditions, for example, if flying sparks are created 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 excessive accumulation of powdered metal may cause electrical 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 complete 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.

The vibration level and noise emission value is given in these instructions have been measured in accordance with a standardized 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 organizing workflows correctly.

Assembly

Pull the plug out of the socket before carrying out any work on the power too l.

Changing the Sanding Sheet
To remove the sanding sheet (8), lift it from the side and pull it from the sanding pad (11). Remove dirt and dust from the sanding pad (11), e.g. with a paintbrush, before attaching a new sanding sheet. The surface of the sanding pad (11) is fitted with a hook and loop fastening, allowing sanding sheets with a hook-and-loop backing to be secured quickly and easily. Press the sanding sheet (8) firmly onto the underside of the sanding pad (11). To ensure optimum dust extraction, make sure that the punched holes in the sanding sheet (8) are aligned with the drilled holes in the sanding pad (11).
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 (11) immediately. Remove the sanding sheet or polishing tool. Unscrew the screw (10) completely and remove the sanding pad (11). Attach the new sanding pad (11) and retighten the screw so that it is finger-tight.
Note: Pads with diameters of 150 mm and 125 mm have different 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 center authorized 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 reactions and/or cause respiratory illnesses in the user or in people in the near vicinity. Certain dust, such as oak or beech dust, are classified as carcinogenic, especially in conjunction with wood treatment additives (chromate, wood preservative). Materials containing asbestos may only be machined by specialists.
– Use a dust extraction system that is suitable for the material 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. When sanding, it is recommended that you connect the power tool to a dust extractor. The power tool has no blower of its own; dust bags cannot be used.
External Dust Extraction
Connect the extraction hose (accessory) either to the extraction pipe (3) or directly to the extraction outlet (4) of the power tool.
Note: The extraction pipe (3) consists of antistatic material. If an antistatic extraction hose (accessory) is used in addition, this will prevent an electrostatic charge from building on the tool, which can happen on occasion when sanding. When working without dust extraction (e.g. polishing), you can remove the extraction pipe (3). To do this, press the release button (15) and pull the extraction pipe (3) backward out of the power tool. The dust extractor must be suitable for the material being worked on.
When extracting dry dust that is especially detrimental to health or carcinogenic, use a special dust extractor.

Auxiliary Handle

The auxiliary handle (5) enables comfortable handling and optimum power distribution, with a high sanding removal rate in particular. Secure the auxiliary handle (5) in the thread (13) on either the right or left of the housing. To achieve better control of the power tool during sanding applications, it is recommended that you place your other hand on the front hand rest. The auxiliary handle (5) may exert lateral forces which could cause the power tool to wobble. This can result in damage to the surface to be sanded, as well as the pad.
Corner protection
The corner protection (12) protects the sanding pad when sanding areas close to the edges. Fix the corner protection (12) onto the power tool from the front. To remove it, pull the corner protection (12) forward and off by one end.

Operation

Starting Operation

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

Switching On/Off

• Make sure that you are able to press the On/Off switch without releasing the handle. To switch on the power tool, push the on/off switch (2) forward. To switch off the power tool, push the on/off switch (2) backward.

Preselecting the orbital stroke rate
You can even preselect the orbital stroke rate during operation using the necessary orbital stroke rate preselection thumbwheel (1).
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 material and the work conditions and can be determined using practice tests.
The Constant Electronic keeps the orbital stroke rate at no load and under load virtually consistent, guaranteeing uniform performance.
After working at a low orbital stroke rate for an extended period, you should operate the power tool at the maximum orbital stroke rate for approximately three minutes without load to cool it down.
Selecting the Material Removal Rate
Two operating modes with different material removal rates are available. For coarse sanding, push the mode selector switch (14) forward; for fine sanding, push the mode selector switch (14) backward until you hear it click into place.
Do not change the operating mode while sanding! This poses a risk of injury.
Coarse Sanding Operating Mode (Positive Drive Control)
This operating mode has a very high sanding removal rate and is recommended for machining extremely rough and non-sensitive surfaces, as well as for rough polishing. The positive drive control of the sanding pad achieves a consistent eccentric and rotational movement.
Fine Sanding Operating Mode (Free Running)
This operating mode is recommended for handling sensitive surfaces, as well as for fine polishing. The free-running of the sanding pad achieves a rotational movement that is dependent on the contact pressure with a constant eccentric movement. In addition, the sanding removal rate can be varied by changing the contact pressure.
Working Advice

• Pull the plug out of the socket before carrying out any work on the power tool.
• Always wait until the power tool has come to a complete stop before placing it down.
• Do not put the power tool down on its side. This could permanently warp the sanding pad.
• This power tool is not suitable for bench-mounted use.
  It must not be clamped into a vice or fastened to a workbench, for example.

Sanding Surfaces
Switch the power tool on, place the entire sanding surface against the surface of the workpiece and apply moderate pressure as you move the sander over the workpiece. The material removal rate and sanding result are primarily determined by the choice of sanding sheet, the preselected orbital stroke rate level, and the contact pressure. Only immaculate sanding sheets achieve good sanding performance and make the power tool last longer. Be sure to apply consistent contact pressure in order to increase the lifetime of the sanding sheets.
Excessively increasing the contact pressure will not lead to increased sanding performance, rather it will cause more severe wear on the power tool and on the sanding sheet. Do not use a sanding sheet for other materials after it has been 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 a higher orbital stroke rate and a higher material removal rate is achieved.
Fine Sanding
Attach a fine-grit sanding sheet.
You can reduce the sanding plate orbital stroke rate by lightly varying the contact pressure or changing the orbital stroke rate level; the random orbit motion will be retained.
Move the power tool with moderate pressure flat on the workpiece in a circular motion or alternately along and across it. Do not tilt the power tool in order to avoid sanding
through the workpiece, e.g. veneers. Switch the power tool off after completing the operation.
Polishing
Note: For polishing, you can remove the extraction pipe (3); this will enable you to handle the tool more easily without damaging the workpiece.
For polishing weathered lacquers and redressing scratches (e.g. acrylic glass), the power tool can be fitted with an appropriate polishing tool, e.g. lambswool bonnet, polishing
felt or polishing sponge (accessory).
Select a low orbital stroke rate (level 1–2) when polishing in order to avoid heating up the surface excessively. Apply the polish to an area slightly smaller than the area which you intend to polish. Using the appropriate polishing tool, work in the polish with either linear or circular movements and with moderate pressure. Do not allow the polish to dry out on the surface; this may damage the surface. Do not expose the surface which you intend to polish to direct sunlight. Clean the polishing tools regularly to ensure good polishing results. Wash the polishing tools with mild detergent and warm water; do not use thinning agents. Clean the extraction outlet (4) regularly; this will ensure perfect dust extraction for subsequent grinding applications.
