[5] CHECKING OIL LEVEL AND REFILLING OIL IN HYDRAULIC OIL TANK
• The oil may spout out when the cap of the hydraulic oil tank is removed.
Remove the cap to relieve internal pressure by slowly rotating it first.
• Do not refill oil exceeding the level gauge (H) (upper limit). When the oil goes beyond
this level, it may spout out from the air breather during traveling or crane operation,
causing burns.
• Be careful not to let any foreign substance go into the filler opening when refilling the
oil.
• Securely close the tank cap after refilling.
If the tank cap falls during the operation, the hot oil may spout out of the pan, causing
burns.
CAUTION
• See “INSPECTION AND MAINTENANCE 6.1 USE OF LUBRICATING OIL ACCORDING TO
TEMPERATURES” for the oil to be used.
• Be sure to put the machine in the travelling posture when checking the oil level.
Checking the oil level in the working position will cause overfilling since the oil in the
cylinders has not returned to the tank.
1. Place the machine on a level surface.
2. Check the oil level gauge (G) in the front side of the
operation side cover and ensure that the oil level is
between “H” and “L”.
3. If there is not sufficient oil, refill the hydraulic oil
according to the following procedure.
(1) Turn “ON” (release) the override switch.
NOTES
When the override switch is turned to the “ON” (release)
position, a warning buzzer sounds intermittently.
(2) See “OPERATION 2.19 BOOM DERRICKING
OPERATION” and raise the boom to the
appropriate height for operation and stop the
engine.
(3) Remove the mounting bolts (2) (2 bolts) and then
remove the inspection cover (1).
(4) Remove the filler cap (F) at the top of the hydraulic
oil tank.
(5) Refill the hydraulic oil from the filler opening (F)
while keeping an eye on the oil level gauge (G).
(6) Securely close the filler cap (F) after refilling.
(7) Place the cover (1) on the original position and
tighten the mounting bolts (2) (2 bolts) securely.
