[5] REPLACEMENT OF HYDRAULIC OIL SUCTION FILTER
• Various parts are at elevated temperatures immediately after engine operation. Do not
replace the filter immediately. Wait until the oil is cooled.
• The oil may spout out when the filler cap of the hydraulic oil tank is removed.
Remove the filler cap to relieve internal pressure by slowly rotating it first.
• Securely close the filler cap after refilling.
If the filler cap falls during the operation, 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.
If you check the oil level in the working posture, you judge the oil level to be low and
feed the oil excessively.
• After replacing the filter of hydraulic oil, do not start the engine for a while until piping
and hydraulic equipment are filled with the oil.
• 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.
• Be careful not to let any foreign substance go into the filler opening when refilling the
oil.
1. Place the machine on a level surface.
2. See “OPERATION 2.14 OUTRIGGER SETTING
OPERATION” to set all the outriggers.
NOTES
After installing the outrigger, raise the machine body
slightly.
3. See “OPERATION 1.12 OPERATION SIDE COVER”
and remount the operation side cover.
4. Remove the mounting bolts (4) (6 bolts) of the flange (3)
at the top of the hydraulic oil tank.
5. Remove the flange (3) and suction filter (5) at the top of
the hydraulic oil tank.
6. Install a new suction filter (5) inside the tank.
7. Place the flange (3) on the original position and apply
liquid packing to the O-ring (6), and tighten the
mounting bolts (4) (6 bolts) securely.
NOTES
Wipe away cleanly whenever the oil spills.
