Check / Add Hydraulic Oil
Before checking or adding hydraulic oil, read the
maintenance precautions in “Handling and
Service of Hydraulic Oil and Filters” on page 5-7.
WARNING! The following safety messages
address a potential Burn Hazard:
• Relieve internal pressure by slowly rotating
the hydraulic tank filler cap during removal.
• Make sure the hydraulic tank filler cap is
closed properly after adding oil.
• When filling the hydraulic oil tank, do not fill
above the upper limit on the level gauge.
Overfilling may cause oil to gush from the
tank during machine operation.
1. Stop the machine on a level location.
2. Rotate and set the outriggers outward to
stabilise the machine. See “OUTRIGGER
SETTING” on page 4-38.
3. Check the oil level gauge (G) in the left side of
the machinery cover and ensure that oil is
sufficient to reach the level point (red point).
