Precautions
•
Use safety glasses and protective gloves.
•
Never work on a pressurized system.
•
Never adjust a pressure relief valve to a higher pressure than
recommended by the manufacturer.
•
Replace the damaged hydraulic or pneumatic hose before con‐
tinuing to work with the machine. Check the hose connections
thoroughly.
•
Use fluid when checking for leaks.
•
Never blow clothes clean with compressed air.
•
Discarded accumulators must first be punctured before they
are deposited as waste to avoid risk of explosion. Drill a hole of
about 3 mm diameter carefully in the accumulator after
depressurizing.
•
Never use your bare hands to detect a leak. A fine high-pres‐
sure stream from a hydraulic hose can easily penetrate the
skin and cause very severe injuries.
Coolant
The coolant in the machine's cooling system consists of water, anti-
corrosion compound, and (when needed) antifreeze fluid, for exam‐
ple, ethylene glycol.
Coolant must not be drained into the sewer system or directly onto
the ground.
Risks
The cooling system is pressurized when the engine is warm. Hot
coolant can jet out and cause scalding when the expansion tank cap
is opened or if there is a leak in the system.
Inhaling ethylene glycol and anti-corrosion compound is dangerous
and hazardous to health.
Precautions
•
Use protective gloves and safety glasses if there is a risk of
splashing or spraying.
•
Open the expansion tank cap carefully so that the pressure is
released from the cooling system. Hot steam and coolant may
stream out.
•
Avoid working with the cooling system when the coolant is hot.
Refrigerant
Refrigerant is used in the machine's air conditioning system.
Risks
The air conditioning system operates with refrigerant at high pres‐
sure. Escaping refrigerant can cause freeze burns.
Heated refrigerant, for example during the repair of leaks in the air
conditioning system, produces gases that are very toxic if inhaled.
