of injury (cuts or burns).
▶ Avoid skin contact with the slurry created when using the wet cutting method.
▶ Cutting material containing asbestos is not permissible.

your fingers. Exposure to vibration during long periods of work can lead to disorders of the blood vessels
and nervous system in the fingers, hands and wrists.
▶ Consult the responsible structural engineer, architect or person in charge of the building project before
starting work. Slits cut into load-bearing walls or other structures can influence the statics of the structure,
especially when reinforcing bars or load-bearing components are cut.

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.
▶ 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.
