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.
· Press the air breather button to relieve
the internal pressure from the tank.
• Before performing maintenance on top
of the work bench, clean the footing and
observe the following precautions to
prevent falling.
· Do not spill oil or grease.
· Do not leave tools scattered around.
· Watch your step when walking.
• Never jump down from the machine or
the work bench. When getting on or off
the machine or work bench, use the
steps, handrails or work bench to
support your body. Your weight should
be evenly distributed among the three
contact points (one hand and two feet
or two hands and one foot).
• Do not stand on the dozer blade and
perform maintenance work. Doing so is
dangerous because of the unsteady
foothold. Use the work bench.
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 retract the cylinders (second boom,
arm and bucket), and lower the bucket to
the ground.
3. Lower the dozer blade, and then stop the
engine.
4. Open the right side cover.
5. Inspect the oil level using the sight gauge
(1).
· When the oil temperature is about 20°C
(68°F):
The level should be between the upper
limit (H) and the 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 slightly below the
upper limit (H).
Replenishing
IMPORTANT: Do not fill up to the level
higher than the upper limit (H). It will
damage the hydraulic circuits or result in
oil spurting. If accidentally done, stop the
engine and wait the hydraulic oil to cool,
and then let the excessive oil to drain
from the drain plug.
1. Press the air breather button (2) to relieve
the internal pressure from the tank.
2. Remove the plug (3).
3. Add the hydraulic oil up to the middle of
the sight gauge (1).
4. Tighten the plug (3).
