25-3-4. Checking and replenishing the hydraulic oil in the hydraulic oil tank
1) Park the machine as illustrated in the figure at the right.
If the machine is not in that posture, start the engine, re-
tract the bucket and arm cylinders to their stroke ends
at low speed, lower the boom until the bucket teeth are
on the ground, lower the blade to the ground, and stop
the engine.
2) Check the oil level with the oil level gauge on the left
side of the machine.
Check that the oil level is between the upper and lower
limit marks.
IMPORTANT
Do not replenish hydraulic oil above the upper limit
mark on the oil level gauge. An excessive amount of
hydraulic oil may damage the hydraulic system by
placing stress on its components, causing a danger-
ous high-pressure leak.
3) Remove the hydraulic oil tank cover (1) and add oil to
the oil supply port (F) if the oil level is below the lower
limit.
See Section "21. Fueling, Oiling and Greasing Based
on Temperature Range" for the hydraulic oil to be used.
Note :
As the oil level differs with the oil temperature, check the
oil level by referring to the following guidelines:
• Before start-up : Near the middle of the oil level gauge
[oil temperature 50 to 86 ° F (10 to 30 ° C)]
• During normal operation : Near the upper limit of the oil
level gauge [oil temperature 122 to 176
°
F (50 to 80
°
C)]
When removing the cap of the oil supply port,
slowly loosen it to gradually relieve the internal
pressure in the tank, or oil may spurt from the tank.
