OPERATION
CHECK OIL LEVEL IN HYDRAULIC TANK, ADD OIL
When removing the oil filler cap, oil may spurt out, so turn the cap slowly to release the internal pressure
before removing the cap.
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. Open the door of the pump room on the right side of the
machine and check sight gauge (G). The oil level should
be between the H and L lines.
NOTICE
Do not add oil if the lebel is above the H line. This will dam-
age the hydraulic equipment and cause the oil to spurt out.
3. If the oil level is below the L line, add oil through oil filler
(F) at the top of the hydraulic tank.
REMARK
The oil level will vary depending upon the oil temperature.
Accordingly, use the following as a guide:
Before operation: around L level
(Oil temperature 10 to 30ºC (50 to 86ºF))
Normal operation: around H level
(Oil temperature 50 to 80ºC (122 to 176ºF))
