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 con-
tact the ground, lower the blade to the ground, and stop
the engine.
2) Check the oil level by reading the oil level gauge on the
left side of the machine. Confirm that the oil level is be-
tween 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.
For the quality of the oil to be used, refer to Section "21.
Fueling, Oiling and Greasing Based on Temperature
Range".
Note :
Note that the oil level varies with the oil temperature.
When reading the oil level, follow these guidelines:
• Before start-up, the oil level gauge should read at or near
the midpoint of the gauge scale
[oil temperature : 50 to 86°F (10 to 30°C)].
• During normal operation, the oil level gauge should read
at or near the upper limit mark of the gauge scale
[oil temperature : 122 to 176°F (50 to 80°C)].
When removing the plug of the oil supply port,
slowly loosen it to gradually relieve the internal
pressure in the tank, or oil may spurt from the tank.
