Figure 1-2 Oil Level Sight Gauge
Examine the oil level on the hydraulic oil
tank, i.e., level shall fall within the M range
shown as Figure 1-2, and in the case of
level lower than L, it is necessary to add
hydraulic oil.
2) Inspect hydraulic oil leakage every 8 h or
daily.

!
Caution: Personal injury danger,
i.e., leaking hydraulic oil can penetrate
or burn skin. Wear goggles and
protective gloves.
Leakage of high-pressure oil may be
invisible to eyes, use cardboard or wooden
boards as a search tool for hydraulic oil
leakage. Hands shall be prohibited from
being used for leakage confirmation.
Inspect oil drops or residual oil on the
following components:
Hydraulic oil tank, filter, pump, hydraulic oil
cylinder, motor, reduction gear, valve block
and hydraulic tubing.
Inspect oil drops or residual oil at the
following areas:
Rear of boom, fly jib, upper side of turntable,
upper and lower sides of chassis, and ground
underneath equipment.
1) Test or replace hydraulic oil every 1,000 h
or annually.

!
C
aution: If the oil isn’t replaced
after the two year interval, it must be
tested quarterly and replaced when it
no longer passes the testing.
Replace hydraulic oil suction filter, oil return filter
every 1000 h or every year. Replace oil suction
filter, oil return filter after first 500 h of use. It is
necessary to replace the hydraulic filter to
maintain performance and service life of the
machine. Dirt or a clogged filter may cause
performance
degradation
of
hydraulic
components, and continuous use will cause
damage
to
components.
In
dirty
work
environments it is necessary to increase the
change intervals.
1.4 Checking the battery
This check should be performed every 250h or
two month, whichever comes first.
Good battery condition is critical to normal
vehicle performance and safe operation.
Improper electrolyte levels or damaged cables
and wires may result in component damage and
dangerous situations.

!
Risk of electric shock
Any live operation can cause serious
personal injury or death. Remove all
rings, watches and other accessories
before operation.
△
!
Risk of bodily injury
The battery electrolyte is corrosive.
Avoid contact with spilled electrolytes
on your hands or other parts of your
body for fear of injury. The spilled
electrolyte can be neutralized with
soda and water.
△
!
Caution: The following checks
should be performed after the battery
is charged.
1) Wear protective clothing and goggles.
2) Make sure the battery cable is securely
wired and not corroded.
3) Make sure the battery lock lever is secure.
4) Remove the battery vent cap.
5) Check the battery electrolyte level. If
necessary, add the distilled water from the
bottom of the battery filler tube. Do not add
excessive distilled water
6) Reset the vent cap.

Caution:
Adding
terminal
protectors and anti-corrosion sealants
will help eliminate corrosion on battery
terminals and cables.
