Maintenance 1
Maintenance overview
Information on residual pressure in the hydraulic system
• A fine jet of hydraulic oil under high pressure can penetrate through the
skin. Seek medical attention immediately if oil penetrates the skin or
eyes.
• Only open hydraulic systems after the pressure in them has been
released.
• Even if the machine is parked on level ground with its loader unit fully
lowered and its engine stopped, there can still be considerable residual
pressure in parts of the hydraulic system.
• Residual pressure is only slow to ease.
➥ If the hydraulic system is opened immediately after shutting down
the machine, release the pressure in the hydraulic system first.
• On machines equipped with hose burst valves on the lift and/or tilt
cylinder, open the valves in order to lower the loader unit –
see “Releasing residual pressure in the hydraulic system” on
page E-32.
Information on hardware, pipeline, hydraulic hoses
• Replace hydraulic hoses after a maximum six years.
• Have any leaks in the line system rectified immediately.
• A fine jet of hydraulic oil under high pressure can penetrate through the
skin. Seek medical attention immediately if oil penetrates the skin or
eyes.
• Do not search for leaks with your hands.
➥ Search for leaks using cardboard or paper on which the escaping
oil can been seen.
• Do not repair damaged pipe lines and hydraulic hoses, but replace
them immediately by new ones.
Information on engine exhaust
• Engine exhaust is hazardous to your health.
➥ Do not breathe in engine exhaust.
• If maintenance and inspection work has to be performed in enclosed
spaces with a running engine, extract the exhaust gases with an
extraction system and ensure that the space is well ventilated.
