MAINTENANCE
Daily Inspection (Every 10 Hours)
Inspecting the Hydraulic Oil Level
and Replenishing
WARNING
Oil may spurt out if caps or filters are
removed or pipes disconnected before
releasing the pressure in the hydraulic
system.
¡ ¡ ¡ ¡ ¡ Gradually loosen the vent plug to
relieve tank pressure.
Inspection
The oil level changes according to the oil
temperature. Inspect the oil level in the
hydraulic oil level inspection posture shown
in the diagram.
¡ Hydraulic oil level inspection posture
1. Start the engine and run it at low speed.
2. Fully retract the arm and bucket cylinders
and ground the bucket.
3. Ground the dozer blade, then stop the
engine.
4. Inspect the oil level using the sight gauge
(4).
• When the oil temperature is about 20°C
(68°F):
The level should be halfway between the
upper limit (H) and lower limit (L).
If it is below the lower limit (L), replenish.
• When the oil temperature is about 50 to
80°C (122 to 176°F):
The level should be near the upper limit
(H).
