Bosch Power Tools 1 609 92A 76U | (25.02.2022)6 | English English Safety Instructions General Power Tool Safety Warnings WARNING Read all safety warnings, instruc- tions, illustrations and specifica- tions 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 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. 1 609 92A 76U | (25.02.2022) Bosch Power ToolsEnglish | 7 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 Warning: Danger of fire! Avoid overheating the work- piece and the sander. Always empty the dust con- tainer 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 ignite under un- favourable conditions. 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 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. 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 Connect the power tool to a mains supply that is prop- erly connected to earth. The socket and extension cable must have a fully functioning protective conductor. 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 (seefigureA) To remove the sanding sheet(14), lift it from the side and pull it off the intermediate pad(15). Remove dirt and dust from the intermediate pad(15), e.g. with a paintbrush, before attaching a new sanding sheet. The surface of the intermediate pad(15) 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(14) firmly onto the underside of the intermediate pad(15). To ensure optimum dust extraction, make sure that the punched holes in the sanding sheet(14) are aligned with the punched holes in the intermediate pad(15) and the drilled holes in the sanding pad(17). Note: An intermediate pad(15) is not required when work- ing with the medium-hard sanding pad; the sanding sheet(14) is attached directly to the sanding pad(17). In all other cases, the change is performed as described here. Selection of the Sanding Plate Soft sanding pad set
