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 installing the water pump, make sure that the maximum permitted water supply pressure of 87 psi
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 cutting discs
▶ Use only cutting discs 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 cutting disc comply with the capacity rating of
the product.
▶ Never use cutting discs that are damaged, run untrue or vibrate.
▶ Do not use damaged diamond cutting discs (cracks in the steel disc, broken or polished segments,
damaged arbor hole, bent or distorted steel disc, heavy discoloration due to overheating, steel disc 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 cutting disc, always take care to ensure that the disc’s specified direction of rotation
corresponds to the direction of rotation of the spindle. Always install only one cutting disc.
▶ The cutting disc and flange or any other accessory must fit the arbor of the product exactly. Cutting
discs 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 cutting disc.
▶ Always use an undamaged clamping flange of the correct diameter which fits the cutting disc used.
The correctly fitting clamping flange supports the cutting disc and thus reduces the possibility of disc
breakage.
