MAINTENANCE PROCEDURES
7. Rinse out the inside of the tank using a mild solvent,
and open the drain plug to empty the solvent.
8. After the hydraulic tank becomes dry, re-install the
hydraulic tank cover and attach the suction hose
and return hose to the hydraulic tank.
9. Add new hydraulic oil as needed.
D-4 Replace Hydraulic Tank Suction
Filter
Regularly replacing hydraulic tank suction filter is vital
to good machine performance and extending service
life. Dirty hydraulic oil may cause the machine to
function improperly and continued use may result in
hydraulic component damage. Extremely dirty condition
requires the oil changes to be performed more
frequently.
When performing the procedure D-3 Replace
Hydraulic Oil, page 5-35, the hydraulic tank suction
filter must also be replaced.

D-5 Replace Coolant and Coolant
Hoses (water-cooled engine)
Regularly replacing the coolant and coolant hoses is
vital to good engine performance and extending service
life. Unqualified cleanliness coolant may cause the
machine to function improperly and continued use
could result in hydraulic component damage. Extremely
harsh condition requires the coolant changes to be
performed more frequently.
BURN AND HIGH PRESSURE
HAZARD
Before replacing the coolant, allow
the fluid in the coolant tank to cool
down to room temperature.
NOTICE
Shut off the engine before inspection.
1. Open the right side cover of turntable, and locate
the coolant tank.
2. Disconnect the the coolant return hose, and drain
the coolant inside the return hsoe into a suitable
vessel.
3. Open the coolant tank cover.
4. Open the coolant tank drain valve to completely
drain the coolant into a suitable vessel.
5. After the coolant is fully drained, close the drain
valve.
6. Remove the coolant hose clamp, and remove the
coolant hoses from each connector.
7. Install the clamp onto the new coolant hose, and
attach the hose to the corresponding connector.
8. Secure the hose clamp in place.
9. Add new coolant into the tank until the coolant level
reaches the fill port of the tank.
10. Clean up the coolant spills in performing the
procedure.
11. Start the engine from the ground controller to
circulate the coolant in the cooling system.
12. Shut off the engine.
D-6 Replace Fuel Hoses
Regularly replacing the fuel hoses is vital to safe engine
operation and extending service life. Long-time use of
old, frayed or broken fuel hoses may pose dangers to
machine operation.
