MAINTENANCE
INSPECTING THE HYDRAULIC OIL TANK
LEVEL AND REPLENISHING
Oil may spurt out if caps or filters are
removed or pipes are disconnected
before releasing the pressure in the
hydraulic system.
• Gradually loosen the vent plug to relieve
tank pressure.
Inspection
The oil level changes with the oil
temperature. Inspect the oil by maintaining
the machine at posture shown in the figure at
the next.
• Machine posture for inspecting the
hydraulic oil level
DAILY INSPECTION (EVERY 10 HOURS)
1. Start the engine and run it at low speed.
2. Fully extend the crawler width.
3. Fully retract the cylinders (arm and
bucket), and lower the bucket to the
ground.
4. Lower the dozer blade, and then stop the
engine.
5. Open the engine hood.
6. Inspect the oil level using the sight gauge
(1).
· When the oil temperature is about 20°C
(68°F):
The proper oil level should be in the
middle of the sight gauge (1).
If the level is lower, replenish.
Replenishing
IMPORTANT: Do not fill up to the level
higher than the middle level of the sight
gauge (1). Doing so will damage the
hydraulic circuits or result in oil spurting.
If filled over the middle level, stop the
engine, wait for the hydraulic oil to cool
and then let the excessive oil drain from
the drain plug.
IMPORTANT: Do not forget to apply
pressure to the hydraulic oil tank to avoid
damage to the pump caused by air
sucking. (If not equipped with the air
breather)
1. Slowly loosen the air bleeding plug (2) to
relieve the internal pressure, and then
remove it.
2. Add hydraulic oil up to the midpoint of the
sight gauge (1).
3. Pressurize the hydraulic oil tank as follows.
Note: For a machine equipped with the air
breather, no pressurization is necessary.
