Work area safety a. Keep work area clean and well lit. Cluttered or dark areas invite accidents. b. Do not operate power tools in explosive at- mospheres, such as in the presence of am- mable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes. c. Keep children and bystanders away while op- erating a power tool. Distractions can cause you to lose control. Electrical safety a. 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. Unmodied plugs and matching outlets will reduce risk of electric shock. b. Avoid body contact with earthed or ground- ed surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded. c. Do not expose power tools to rain or wet con- ditions. Water entering a power tool will increase the risk of electric shock. d. Do not use the cable for another purpose, for example, carrying or hanging the power tool or pulling the plug out of the socket. Keep the cable away from heat, oil, sharp edges or moving device parts. Damaged or coiled cables in- crease the risk of an electric shock. e. If you work with a power tool outdoors, only use extension cables that are also suitable for outdoor use. Using an extension cable suitable for outdoor use reduces the risk of an electric shock. Only use approved and appropriately identied ex- tension cables for use outdoors. Only use cable reels in the unrolled state. f. If operating a power tool in a damp loca- tion is unavoidable, use a residual current circuit breaker with a trigger current of 30 mA or less to protect the power supply. Use of an RCD reduces the risk of electric shock.

5. General safety information

WARNING! Read all safety information, instructions, il- lustrations and technical data for this electric tool. Failure to follow all instructions listed below may result in electric shock, re and/or serious injury. Save all warnings and instructions for future ref- erence. The term “power tool” used in the safety instructions refers to mains-powered electrical tools (with a mains cable) and battery-powered electrical tools (without a mains cable).www.scheppach.com

Power tool use and care a. Do not overload the device. 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. b. Do not use the power tool if the switch does not turn it on and o󰀨. Any power tool that can- not be controlled with the switch is dangerous and must be repaired. c. Disconnect the plug from the power source and/or remove the battery pack, if detachable, from the power tool before making any adjust- ments, changing accessories, or storing pow- er tools. Such preventive safety measures reduce the risk of starting the power tool accidentally. d. 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. Unused power tools should be stored in a dry, el- evated or closed location out of the reach of chil- dren. e. Maintain power tools and accessories. Check whether moving parts function properly and do not get stuck and whether parts are broken or are damaged and thus adversely a󰀨ect the electric tool function. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools. f. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control. g. 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 op- erations di󰀨erent from those intended could result in a hazardous situation. h. 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. Personal safety a. 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 inuence of drugs, alcohol or med- ication. A moment of carelessness when using electrical tools can result in serious injuries. b. 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 per- sonal injuries. c. Prevent unintentional starting. Ensure the switch is in the o󰀨-position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your nger on the switch or energising power tools that have the switch on invites accidents. d. Remove any adjusting key or wrench before turning the power tool on. A tool or spanner that is located in a rotating de- vice part may result in injuries. e. Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unex- pected situations. f. Dress properly. Do not wear loose clothing or jewellery. Keep hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts. Rubber gloves and anti-slip footwear are recom- mended when working outdoors. Tie long hair back in a hair net. g. If dust extraction and collection devices can be mounted, make sure that they are connect- ed and used properly. Use of dust collection can reduce dust-related hazards. h. 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 injury within a fraction of a second.www.scheppach.com
