2.3 Electrical safety
▶ Before beginning work, check the working area for concealed electric cables or gas and water pipes.
External metal parts of the machine may give you an electric shock if you damage an electric cable
accidentally.
▶ Organize in advance the work to be performed, after examining the location. Check whether warning
signs have to be set up and a safe working distance from other persons defined.
2.4 Safety at the workplace
▶ Ensure that the workplace is well lit.
▶ Don't work in closed rooms. Carbon monoxide, unburned hydrocarbons and benzene in the exhaust gas
may cause asphyxiation.
▶ Keep the workplace tidy. Objects which could cause injury should be removed from the working area.
Untidiness at the workplace can lead to accidents.
▶ Hot exhaust gases containing sparks or sparks generated by the cutting operation may cause fire or
explosion. Make sure that the sparks generated do not ignite flammable (gasoline, dry grass, etc.) or
explosive (gas, etc.) substances.
▶ Fit the filled water tank only after the saw has been mounted on the saw trolley. This will help to prevent
the trolley falling over.
▶ Do not stand the product and the saw trolley on an inclined surface. Always check to ensure that the
product and the saw trolley are standing securely.
▶ After installing the water pump, make sure that the screws are tightened to the recommended tightening
torque.
▶ Before fitting the water pump, check to ensure that the maximum permitted water supply pressure of 6
bar is not exceeded.
2.5 Liquids (gasoline and oil) and vapors
▶ The inhalation of gasoline vapors and skin contact with gasoline may be hazardous to the health.
▶ Avoid direct skin contact with gasoline. Wear protective gloves.
▶ If your clothing becomes soiled with gasoline, it is essential to change your clothing.
▶ Ensure that the workplace is well ventilated in order to avoid breathing in gasoline fumes.
▶ Use a fuel container that complies with the applicable regulations.
▶ Don't refuel the product while the engine is running. Wait until the engine has cooled down.
▶ Never smoke while refueling; there is a risk of fire and explosion.
▶ Do not refuel the product in the area where you are working (move at least 3 meters/10 feet clear of the
workplace). When refueling, take care to avoid fuel spillage. Use a suitable funnel.
▶ Avoid inhaling gasoline vapors and exhaust fumes. Take care to ensure adequate ventilation.
▶ Don't use the gasoline or other flammable liquids for cleaning.
2.6 Cutting work using cut-off wheels
▶ Use only cut-off wheels with a rated maximum permissible speed at least as high as the maximum
spindle speed.
▶ Check that the outside diameter and the thickness of the cut-off wheel comply with the capacity rating
of the product.
▶ Never use cut-off wheels that are damaged, run untrue or vibrate.
▶ Do not use damaged diamond cut-off wheels (cracks in the steel cut-off wheel, broken or polished
segments, damaged arbor hole, bent or distorted steel cut-off wheel, heavy discoloration due to
overheating, steel cut-off wheel worn away beneath the segments, diamond segments with no lateral
overhang, etc.).
▶ Do not use toothed accessory cutting tools (e.g. toothed saw blades).
▶ When fitting the cut-off wheel, always take care to ensure that the wheel's specified direction of rotation
corresponds to the direction of rotation of the spindle. Always install only one cut-off wheel.
▶ The cut-off wheel and flange or any other accessory must fit the arbor of the product exactly. Cut-off
wheels with arbor holes that do not match the mounting hardware of the product will run out of balance,
vibrate excessively and can lead to loss of control and to breakage of the cut-off wheel.
▶ Always use an undamaged clamping flange of the correct diameter which fits the cut-off wheel used.
The correctly fitting clamping flange supports the cut-off wheel and thus reduces the possibility of wheel
breakage.
