CAUTION
The dumped engine oil should be disposed in accordance with relevant laws and regulations.
The pit must remain free of used oil. Also prevent the oil from flowing into gully drain or flowing on the ground.
CAUTION
During maintenance of the hydraulic system and when changing hydraulic aggregates keep everything meticulously
clean to avoid a premature failure of the system.
The hydraulic filter system consists of:
•
Return-suction filter for the working and driving hydraulics
• Filling-vent valve
These filters are integrated in the tank. The filling amount in the hydraulic oil tank should be checked daily. The
loader should be on even ground and all cylinders must be retracted.
The return-suction filter element should be replaced at the following intervals under normal working conditions:
a.
50 operating hours after initial commissioning
b. 800 operating hours after initial commissioning
c. Subsequently every 800 operating hours
The filling-vent valve should be cleaned every month and replaced after 800 operating hours; the complete filling
cover should hereby be exchanged.
The following intervals are prescribed for changing the hydraulic oil:
a.
50 operating hours after initial commissioning
b. 800 operating hours after initial commissioning
c. All further 800 operating hours
The hydraulic oil should be drained while still warm during an oil change. Any oil sludge must be removed by rinsing
the tank. Top up with oil through the filling-vent valve.
The hydraulic oil used is HLP 46 (ISO VG 46, acc. to DIN 51519). If other hydraulic fluids are used, these must be
approved by the manufacturer.
Check the hydraulic system for leaks during all service and maintenance work. Leaky union pieces and screw
connections are to be tightened when depressurised and then checked again.
CAUTION
• Following major repairs (e.g. changing pumps or motors) the suction area of the hydraulic pump has to be filled
with oil before starting to vent the hydraulic system.
• The hydraulic tank is pressurized when warm and in use. To prevent spillage of the hydraulic oil when changing
the filter the pressure must be relived by opening the filling vent valve.
