Risks
There are injury risks in connection with work on:
• Hydraulic system (for example, working hydraulics and brake
system).
• Fuel system.
• Tyre repairs.
• Air conditioning.
Safety precautions
• Use safety glasses and protective gloves.
• Never work in on a pressurized system.
• Never adjust a pressure limiting valve to a higher pressure than
recommended by the manufacturer.
• A hydraulic hose that swells, for example, at a connection, is
about to rupture. Replace it as soon as possible! Check connec-
tions thoroughly.
• Use fluid when checking for leaks.
• Never blow clothes clean with compressed air.
• Discarded pressure accumulators must first be punctured be-
fore they are deposited as waste (to avoid risk of explosion).
Carefully drill a hole with 3 mm diameter after depressurizing.
• Never use your hands directly to detect a leak.A fine high-pres-
sure stream from a hydraulic hose can easily penetrate a hand
and causes very severe injuries.

Coolant
The coolant in the machine’s cooling system consists of water, anti-
corrosion compound and (when needed) anti-freeze fluid, for exam-
ple, ethylene glycol.
Coolant must not be drained into the sewer system or directly onto
the ground.
Risks
The cooling system operates at high pressure when the engine is
warm. Hot coolant can jet out and cause scalding in case of a leak
or when the expansion tank cap (filler cap) is opened.
Ingesting ethylene glycol and anti-corrosion compound is dangerous
and hazardous to health.
Safety precautions
• Use protective gloves and safety glasses if there is a risk of
splashing or spraying.
• Open the filler cap first, to release the excess pressure. Open
carefully.Hot steam and coolant can stream out.
• If possible, avoid working on the cooling system when the cool-
ant is hot.
