[2] OIL REPLACEMENT IN HYDRAULIC OIL TANK
• Various parts are at elevated temperatures immediately after engine operation. Do not
change the oil immediately. Wait until the oil is cooled.
• The oil may spout out when the air filter of the hydraulic oil tank is removed.
Remove the air filter to relieve internal pressure by slowly rotating it first.
• Securely close the air filter after refilling.
If the air filter 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 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 filter during traveling or crane operation.
• Be careful not to let any foreign substance go into the filler opening when refilling the
oil.
• Oil drain pan: Prepare a container for at least 120 liters.
• Quantity of oil in hydraulic oil tank for replacement: 110 L

3. See “OPERATION 2.19 BOOM DERRICKING
OPERATION” and raise the boom to the appropriate
height for operation and stop the engine.
