CHECK HYDRAULIC SYSTEM OIL LEVEL
1.
Move machine to a level area and shut
down engine.
2.
Apply parking brake.
3.
Lower bucket to ground.
4.
Check sight gauge that is attached to
hydraulic reservoir. Oil level must be
between upper limit (1, Figure 10) and
lower limit (2) shown on gauge.
5.
To add hydraulic oil, turn the breather cap
(1, Figure 11) slowly to allow the
pressurized air to vent.
6.
Remove the upper cover (2, Figure 11) of
the hydraulic oil tank and add oil to proper
level by checking sight glass (Figure 10).
WARNING!
The hydraulic oil will be hot after normal
machine operation. Allow system to cool
before attempting to service any of the
hydraulic components.
The hydraulic tank is pressurized. Turn the
breather cap slowly to allow the
pressurized air to vent. After the pressure
has been released, it is safe to remove
either the fill cap or service covers.
IMPORTANT
Do not fill above "H" mark on sight
gauge. Overfilling can result in
damage to equipment and oil leaking
from hydraulic tank due to
expansion.
