INSPECT HYDRAULIC OIL
LEVEL
Ensuring appropriate hydraulic oil is important for prop-
er operation of the machine. Operating the machine
with an improper hydraulic oil level can damage hy-
draulic components. Performing daily inspection of the
hydraulic oil level will help you determine if a problem
exists in the hydraulic system. Be sure to correct the
problem before operating the machine.
Perform the following procedures with the platform
retracted:
1.
Open the door on the right side of the chassis.
2.
Inspect the mark on the side of the hydraulic oil
tank.
3.
The hydraulic oil level should appear within “10L
(2.2 gal(imperial)/2.6 gal(US))” and “12L(2.6 gal(im-
perial)/3.2 gal(US))” mark in the hydraulic oil tank.
4.
Add hydraulic oil as needed. Never overfill the tank.
