CHECK OIL LEVEL IN HYDRAULIC TANK, ADD OIL
WARNING
• When removing the oil filler cap, oil may spurt out, so turn the
cap slowly to release the internal pressure before removing
the cap.
• If oil has been added to above the H mark, stop the engine and
wait for the hydraulic oil to cool down, then drain the excess
oil from the drain plug P.
1. If the work equipment is not in the condition shown in the diagram on
the right, start the engine, run the engine at low speed, retract the
arm and bucket cylinders, then lower the boom, set the bucket teeth
in contact with the ground, and stop the engine.
2. Within 15 seconds after stopping the engine, move each control le-
ver (for work equipment and travel) to the full stroke in all directions
to release the internal pressure.
3. Open the pump room door on the right side of the machine. Check
sight gauge G. The oil level is normal if between the H and L marks.
NOTICE
Do not add oil if the level is above the H line. This will damage
the hydraulic equipment and cause oil to spurt out.
4. If the level is below the L mark, remove the upper cover of the hy-
draulic tank and add oil through oil filler F.
For details of the oil to use, see 20. “USE OF FUEL, COOLANT AND
LUBRICANTS ACCORDING TO AMBIENT TEMPERATURE”.
REMARK
The oil level will vary depending upon the oil temperature Accord-
ingly, use the following as a guide:
• Before operation: around L level
(Oil temperature 10 to 30
o
C (50 to 86
o
F))
• Normal operation: around H level
(Oil temperature 50 to 80
o
C (122 to 176
o
F))
