Check / Add Hydraulic Oil
WARNING!
• 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 travelling 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:
• For more information on the which oil to be
used, see "LUBRICATING OIL" on page 5-14.
• Be sure to put the machine in the travelling
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 levelled location.
2. Observe the oil level gauge (G) in the
left-hand machinery cover to check that the
oil level is between the "H" and "L" levels.
Fig. 5-42
3. If there is not sufficient oil, refill with the
hydraulic oil using the following procedure.
(1) See "OUTRIGGER SETTING" on page
4-36 and rotate the outriggers outward.
(2) See "Removing Machinery Cover" on
page 5-18 and remove the machinery
cover. (3) Drain the fuel and water out of
the pot (1).
(3) Remove the filler cap (F) on the top of the
hydraulic oil tank.

(4) Refill with the hydraulic oil from the filler
opening (F) while looking at the oil level
gauge (G).
(5) Securely close the filler cap (F) after
refilling with oil.
(6) See "Installing Machinery Cover" on page
5-18 and install the machinery cover.
(7) See "OUTRIGGER STOWING" on page
4-45 and rotate the outriggers inward to
stow them.
