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 re-
leased.
• Even if the vehicle is parked on level ground with its loader unit fully
lowered and its engine stopped, there can still be considerable resid-
ual 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
vehicle, release the pressure in the hydraulic system first.
• On vehicles equipped with lowering brake valves on the lift and/or tilt
cylinder, open the valves in order to lower the loader unit .
Information on screw connections, pipes, 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 ex-
traction system and ensure that the space is well ventilated.
