[5] INSPECTION OF OIL LEVEL AND REFILLING OIL IN HYDRAULIC OIL TANK
When removing the oil inlet cap, there is a risk oil may spurt out, so take care to turn it slowly
before removing it to relieve internal pressure.
1. If it is not in the state shown on the right, start the engine,
and with the engine at low speed, fully retract the boom,
lowering it to horizontal before stopping the engine.
2. Inspect the level gauge (G). The oil should be between
the H and L lines.
3. If oil is below the L level, remove the cover on the top of
the hydraulic fluid tank and refill it from the filler port (F).
NOTES
The oil level changes with temperature so consider the
following as guides when checking.
• Before operation, near the L level (oil temperature: 10 to
30 °C)
• In normal operation, near the H level (oil temperature:
50 to 80 °C)
4. Set the boom in the completely retracted and fully raised
state, mount the oil feed cap and pressurize the tank.
CAUTION
Omitting pressurization of the hydraulic tank causes
the pump to suck air, resulting in adverse effect on
the units.
CAUTION
Do not add oil above the H line. The hydraulic circuit
may be damaged or the oil may spout out.
If oil is filled inadvertently above the H level, rotate
the upper swivel body so that the drain plug (P) at
the bottom of the tank comes between the left and
right crawler belts, stop the engine, and after the
hydraulic oil has cooled, drain excess oil from the
drain plug (P).
