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.
• When removing plugs or screws, or
when disconnecting hoses, stand to the
side and loosen them slowly to
gradually release the internal pressure
before removing.
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
1. Start the engine and run it at low speed.
2. Fully retract the cylinders (lift arms and
bucket), and lower the bucket to the
ground.
3. Stop the engine.
4. Inspect the oil level using the sight gauge
(2).
· 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) (during operation):
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. Raise the safety bar to the lock position.
2. Loosen the bolt (4) and open the cover (3).
3. Remove the plug (1).
4. Add the hydraulic oil up to the middle of
the sight gauge (2).
5. Tighten the plug (1).
6. Close the cover (3) and tighten the bolt (4).
DAILY INSPECTION (EVERY 10 HOURS)
