Exhaust fumes
Exhaust gases from combustion engines contain carbon monoxide, a colour- and odour-less but
highly toxic gas. The inhalation of minute quantities can be lethal.
Furthermore, diesel exhaust contains soot particles, some of which are noxious.
➤ Do not inhale exhaust fumes.
➤ Park the machine in such a manner that the exhaust cannot blow towards the operators.
➤ Never use the machine in enclosed spaces, only in the open.
Fire and explosion
Spontaneous ignition and combustion of fuel can result in serious injury or death.
➤ Allow no open flames or sparks at the place of use.
➤ Do not smoke while refuelling.
➤ Never refuel the machine when it is running.
➤ Do not allow fuel to overflow.
➤ Wipe up spilled fuel immediately.
➤ Provide a fire extinguisher in the immediate vicinity.
➤ For the operation in combustible environment, fit the machine with a spark arrestor (Option la).
Hot coolant
The cooling system of a liquid-cooled engine at running temperature is under high pressure. If the
filler cap is unscrewed, hot coolant can spray out under pressure and cause severe scalding.
➤ Let the machine cool down before opening the cooling system.
➤ Unscrew the filler cap carefully by a quarter to half a turn at first. Remove the filler cap only
when pressure has escaped completely.
Electricity
Touching voltage-carrying components can result in electric shocks, burns or even death.
➤ Allow only qualified and authorised electricians or trained personnel under the supervision of a
qualified and authorised electrician to carry out work on electrical equipment according to elec‐
trical engineering rules.
➤ Regularly check that all electrical connections are tight and in proper condition.
➤ Switch off any external power sources.
For example, the connection to the electrical engine coolant pre-heater.
Compressive forces
Compressed air is contained energy. Uncontrolled release of this energy can cause serious injury
or death. The following information concerns any work on components that could be under pres‐
sure.
➤ Wait until the compressor has automatically vented (check the pressure gauge: it must read 0
bar)
➤ Then open an outlet valve carefully to ensure that the line between the minimum pressure
check valve and the compressed air outlet is vented.
➤ Do not carry out welding, heat treatment or mechanical modifications to pressurised compo‐
nents (e.g. pipes and vessels) as this influences the components' resistance to pressure.
The safety of the machine is then no longer ensured.
