 Maintenance of hydraulic system
 It is necessary to apply YA-N46 hydraulic oil for hydraulic system, and the
hydraulic shall be changed according to the using status regularly.
 Check the oil level in the oil tank, and add it when it’s lower than the lowest oil
level.
 When adding the oil into the oil tank, the oil must go through the air filter.
 Check and change the oil suction filter inside the oil tank periodically.
 If there is abnormal noise or vibration from the hydraulic system, inspection and
maintenance must be done at once.
5.2.7 Pneumatic System
5.2.7.1 Pneumatic Tailstock
(Refer to Fig 7: Principle diagram of pneumatic tailstock, Fig. 8 and Fig.9: Assembly
drawings)
 Instruction of operating the pneumatic system
The pneumatic tailstock is composed by triple-assy XFRU403 of air resource,
manual valve XQ340661, single-way throttle valve 77101013 and deafener
XQ140600. The air resource triple-assy XFRU403 is mounted on the rear leg of the
machine, and all the others are all mounted on the tailstock.
