[6] CHECKING/REFILLING OIL LEVEL IN HYDRAULIC OIL TANK
• The oil may spout out when the cap of the hydraulic oil tank is removed.
Turn the cap slowly to let the inner pressure escape before removing.
• Do not refill with the oil to the level higher than the “H” (upper limit) of the level gauge. Too
much oil may cause the oil to spout out of the air breather during traveling or crane operation,
causing burns.
• Be careful not to let dust go in from the filler opening when refilling with oil.
• Securely close the tank cap after refilling with the oil.
The tank cap may fall, and the hot oil may spout out, causing burns.
CAUTION
• See “Maintenance 5.1 Use of Lubricating Oil According to Temperature” for which oil to be
used.
• Be sure to put the machine in the traveling posture when checking the oil level.
Checking the oil level in the working posture will cause overfilling since the oil in the cylinders
has not returned to the tank.
• Be careful not to let dust go in from the filler opening when refilling with oil.
1. Stop the machine at leveled location.
2. See “Operation 2.14 Outrigger Setting Operation” to rotate the
rotary of the “outrigger (1)” and “outrigger (2)” outward.
3. Look at the oil level gauge (G) on the right side of the engine
cover to check if the oil level is between “H” and “L”.
4. If there is not sufficient oil, refill with the hydraulic oil using the
following procedure.
(1) Operate the emergency stop cancel switch to the “ON”
(cancel) position.
(2) See “Operation 2.19 Boom Derricking Operation” and raise
the boom to the height at which it is easy for you to work.
Then stop the engine.
(3) Remove the three mounting bolts (2) and remove the
inspection cover (1).
(4) Remove the filler cap (F) on the top of the hydraulic oil tank.
(5) Refill with the hydraulic oil from the filler opening (F) while
looking at the oil level gauge (G).
(6) Securely close the filler cap (F) after refilling with oil.
(7) Replace the cover (1) to the original position and securely
tighten three mounting bolts (2).
5. See “Operation 2.24 Outrigger Stowing Operation” and rotate
the rotary of the “outrigger (1)” and “outrigger (2)” inward and
stow.
