Fluid & Flushing tank
The reservoir tank is equipped with a removable
clean out/inspection plate on the top of the tank.
When the fluid is changed, the clean out plate
should be removed to inspect the tank and remove
any sludge or debris accumulated on the bottom.
Only qualified service technicians should drain and
flush the system or replace hydraulic fluid filters.
WARNING
ALWAYS DEPRESSURIZE THE HYDRAULIC SYSTEM BEFORE
REMOVING ANY HYDRAULIC COMPONENTS, HOSES OR
FITTINGS. FAILURE TO DO SO COULD RESULT IN SERIOUS
INJURY OR DEATH.
NOTICE:
•
BEFORE PERFORMING ANY MAINTENANCE PROCEDURE,
MAKE SURE THE HYDRAULIC SYSTEM IS SHUTDOWN
WITH THE TRUCK IN THE SERVICE POSITION AND ON
LEVEL GROUND.
•
MAKE SURE THE HYDRAULIC TANK, FILTERS AND ALL
RELATED COMPONENTS ARE THOROUGHLY CLEANED
BEFORE SERVICING TO PREVENT CONTAMINATION.
•
MAKE SURE ALL PARTS ARE CLEAN BEFORE FINAL
ASSEMBLY.
Draining and flushing the hydraulic tank:
1. Make sure the hydraulic system is not pres-
surized and the fluid is cool.
2. Drain the tank into a suitable container by
removing drain plug at the bottom of the tank.
3. When the tank is drained, loosen the bolts
securing the inspection plate and remove the
plate. Use a bright light to inspect for sludge
buildup and other contamination.
4.
Remove sludge and contaminates, then flush
the tank until it is clean using fresh hydraulic
fluid.
5.
Coat the seal with hydraulic fluid and install the
plate. Tighten the bolts in a crisscross pattern
to secure the plate.
6. Install the drain plug.
7.
Add fluid until the tank is full. Monitor the fluid
level using the sight gauge.
