Oil for steering system and working hydraulic system
Add oil from the oil filler at the engine oil tank until the oil pointer in the tank points between the upper
and lower oil pointer holes. The oil is used by the system as pressure oil produced by the oil pump. For
the steering gear, add oil from the oil filling pipe to lubricate the recirculating ball pair. Change the
hydraulic oil every 1,200 h.

Injecting grease with pressure
Inject grease with pressure to various sliding bearing or rolling bearing, such as:
(1) Bearings for water pump and fan of diesel engine.
(2) Bearing for transmission shaft cross yoke.
(3) Bearing for control lever.
(4) All pin sleeve pairs at both ends of the oil cylinders.
(5) Hinge pin sleeve pairs for front and rear frames; swing pin sleeve pairs for sub-frame.
(6) Each pin sleeve pair in working device.

II. Regular maintenance
Instruction
1.
Before any operation or maintenance, make sure the instruction manual of the machine
concerning safety, warning and descriptive information has been read and understood completely.
2.
The user is responsible for proper maintenance of the machine, including adjusting mechanism,
adding lubricants and other operating fluids, replacing filters and replacing parts due to normal wear or
aging. Failing to maintain the entire machine according to correct cycles and specified procedures may
lead to a drop in performance to the machine as well as accelerated wear on its parts and
components.
Note
：
1.
Before any continuous maintenance cycle, it is necessary to complete all previous maintenance
work firstly. In completing any item of maintenance work, it is necessary to ensure that any other items
that are supposed to be performed according to cycles shorter than its cycle are done simultaneously
with that item of work. For example, if a collection of items of work supposed to be performed once
every 500 hours or every three months needs to be done, some other items must be performed
simultaneously, including any item supposed to be performed once every 250 hours or every month,
once every 100 hours or half a month, once every 50 hours or every week, or once every 10 hours or
every day.
2.
It is imperative that all maintenance cycles be determined by work time. However, calendar
time-based cycles could replace work time-based ones if calendar time-based maintenance plans turn
