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 u Keep work area clean and well lit. Cluttered or dark areas invite accidents. u 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. u Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control. Electrical safety u 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. u 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. u Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of elec- tric shock. u 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. u 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. u 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 u 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 inatten- tion while operating power tools may result in serious per- sonal injury. u 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. u 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. u 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. u Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations. u 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. u 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. u 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 u 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. u 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. u 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. u 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. u 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. Bosch Power Tools 1 609 92A 5LX | (23.06.2020)6 | English u 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. u 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. u 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 u 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 u Only use the power tool for dry sanding. Water entering a power tool will increase the risk of electric shock. u 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. u 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. u 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. u 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. u Always wait until the power tool has come to a com- plete stop before placing it down. u Secure the workpiece. A workpiece clamped with clamping devices or in a vice is held more secure than by hand. Products sold in GB only: Your product is fitted with an 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 au- thorised 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.

Changing the sanding sheet (see figure A) 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-and- loop fastening, allowing sanding sheets with a similar back- ing 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 are aligned with the drilled holes in the sanding pad. 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 sensit- ive sanding even on curved surfaces – Soft sanding pad: Suitable for all sanding work, universal application – Hard sanding pad: Suitable for heavy sanding on flat sur- faces Changing the sanding pad (see figure B) 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. u Avoid dust accumulation at the workplace. Dust can easily ignite. Self-generated dust extraction with dust box (see figures C1–C4) Before fitting the dust box (6), remove the plastic slider (13). Fit the dust box (6) onto the extraction outlet (14) so that it clicks into place. Make sure that the plastic slider (13) is partly within the bracket (12). To empty the dust box (6), press the locking lever (15) on the side of the dust box (➊). Remove the dust box by pulling it downwards (➋). Before opening the dust box (6), knock the dust box against a firm surface as shown in the figure to loosen the dust from the filter element. Take hold of the dust box (6) by the recessed grip, fold the filter element (16) upwards out of the way and empty the dust box. Use a soft brush to clean the flaps of the filter ele- ment (16). External dust extraction (see figure D) Attach the dust extraction adapter (17) to the extraction outlet (14). Make sure that the locking levers of the dust ex- traction adapter lock into place. A dust extraction hose with a diameter of 19mm can be connected to the dust extrac- tion adapter (17).
