Use the additional handle supplied with the tool. Loss of control can cause personal injury.
Hold the power tool by the insulated gripping surfaces when performing an operation where the cutting accessory may contact hidden wiring or its own cord. A cutting accessory contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.
Always work with the additional handle correctly installed.
Always hold the machine with both hands at the intended handles, take a secure stance and concentrate on the work.
Always wear protective goggles, gloves, and sturdy shoes when working with this tool.
Ensure that the spot where you wish to work is free of power cables, gas lines, or water pipes (e.g. using a metal detector).
If the safety coupling responds, switch off the machine immediately
Do not touch the rotating tool!
Secure the workpiece to prevent slipping or rotation (e.g. by securing with screw clamps).
Remove chips and similar material only with the machine at a standstill.
Caution must be exercised when driving screws into hard materials (driving screws with metric or imperial threads into steel)! The screw head may break or a high reverse torque may build up on the handle.
Pull the plug out of the socket before making any adjustments, changing tools, carrying out maintenance or cleaning.
Avoid inadvertent starts by always unlocking the switch when the plug is removed from the mains socket or whenever the power fails.
A damaged or cracked additional handle must be replaced. Never operate a machine with a defective additional handle.
Safety clutch : f the tool jams or catches, the power supply to the motor is restricted. Due to the strong force which can arise, always hold the machine with both hands using the handles provided, stand securely and concentrate.
Reducing dust exposure:
**** Some of the dust created using this power tool may contain chemicals known to cause cancer, allergic reaction, respiratory disease, birth defects or other reproductive harm. Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, arsenic and chromium from chemically treated lumber, hardwood like oak or beech, metals, and asbestos. The risk from exposure to such a substance will depend on how long you or bystanders are being exposed.
Do not let particles enter the body.
To reduce your exposure to these substances: work in a well-ventilated area, and work with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
Observe the relevant guidelines for your material, staff, application, and place of application (e.g. occupational health and safety regulations, disposal).
Collect the particles generated at the source, and avoid deposits in the surrounding area.
Use suitable accessories for special work. In this way, fewer particles enter the environment in an uncontrolled manner.
Use a suitable extraction unit.
Reduce the exposure to dust with the following:
– do not direct the escaping particles and the exhaust air stream at yourself or nearby persons or on dust deposits.
– Use an extraction unit and/or air purifiers.
– Ensure good ventilation of the workplace and keep clean using a vacuum cleaner. Sweeping or blowing stirs up dust.
– Vacuum or wash the protective clothing. Do not blow, beat or brush.
