[1] REPLACEMENT OF HYDRAULIC OIL RETURN FILTER CARTRIDGE
• As parts and oil become hot immediately after the engine stop, you may suffer burns. Begin work
after the temperature has dropped.
• When removing the cap of oil inlet, there is a risk of oil spurting out. Take care to turn it slowly
while removing internal pressure.
1. Open the gravel cover (1) on the right side of the
vehicle.
2. Remove the cap of oil inlet (F) to relieve the internal
pressure.
3. Loosen the 3 bolts and remove the cover (2). At this
time, the cover may jump off because of spring (3);
keep pressing the cover down while removing the bolts.
4. Take out the element (5) after removing the spring (3)
and valve (4).
5. Clean the removed parts with diesel fuel.
6. Install the new element where the old element (5) was
installed.
Inspect the O-ring to be set between the hydraulic oil
tank and cover (2), and replace it if it is scratched.
7. Set the valve (4) and spring (3) on top of the element.
8. Set the cover (2), and while pushing it with hands,
mount it with the cover mounting bolts.
9. Set the boom in the completely retracted and fully
raised state, mount the oil feed cap and pressurize the
tank.
10. Close the gravel cover (1) on the right side of the
vehicle.
