Hydraulic oil - check/re

ll
1. Adjust the work equipment to the attitude
shown by the right illustration. Check oil
level. Add oil if necessary.
For the type of hydraulic oil used on the
machine see
“
Recommended Fluids
”
on page 5-17.
2. If the work equipment is not in the illus-
trated position, start the engine and run it
at low speed. Properly retract the arm and
bucket cylinders, lower the boom to rest
the arm front end on the ground, and stop
the engine.
3. Within 15 seconds after stoppage, operate
work equipment joystick controls and travel
control levers in all directions in order to
release internal pressure.
4. Open the pump chamber door on the right
in order to check the oil level gauge (G).
Oil level should be maintained between H
and L marks.
Note:
Never add oil to a level above the H mark,
which may ruin hydraulic devices and cause
oil to squirt. If the oil level is above the H mark,
stop the engine and wait for the oil to cool
down. Place a container under the drain plug
(P) beneath the hydraulic tank and discharge
excessive oil from the tank via the drain plug.
5. If the oil level is below the L mark, add
oil through filler opening (F) on top of the
tank.
