Maintenance every 1500 operating hours
Change the hydraulic oil filter
The control light (3) in the dash board monitors the hydraulic oil
filter. The filter element must be changed:
– if the control light (3) lights up at operating temperature of
the hydraulic oil.
– at the latest after 1500 operating hours or once every year.
Note:
Under cold weather conditions the control light may light up
for a short while immediately after starting the engine. This is
caused by the high viscosity of the oil. Run the engine for
about 2 minutes with idle speed.
– Unscrew the air discharge valve (C) from the filter cover (B).
– Loosen the screws on the lid (B), unlock the lid by turning it
counter-clockwise and pull it out.
– Lift the filter element out by the handle.
– Clean the filter bowl.
– Check the seals, replace them if necessary.
– Insert a new filter element.
– Close the lid (B), check for leaks.
– Screw the air discharge valve (C) tightly back in.
– Screw the new breather valve (A) tightly in.
– Check the oil level after the test run.
ATTENTION!
Before opening the filter cover (B) the breather valve (A)
must be unscrewed to relieve the overpressure in the
hydraulic oil tank.
ATTENTION!
Hot oil - danger of scalding!
Catch running out oil and dispose of environmentally
together with the filter element.
