1.2 Inspecting the Drive Hub
Oil Level
1) Inspect the oil level of the drive hubs every
250 h or quarterly. Improper oil level will
result in reduced performance. Continuous
use will result in damage to components.
2) Inspect oil level
Figure 11-1 Traveling slowdown
1. Oil filler 2. Viewing port
Drive the machine until one plug is located
at the horizontal position as shown as
shown in Figure 11-1.
Remove the viewing port plug at the
horizontal position, and inspect oil level.
Result: Oil level shall be flush with the
bottom of the viewing port.
If necessary, add oil at the oil filler until the
oil level is flush with the bottom of the
viewing port, select gear oil by referring to
Machine Specifications section.
Coat the plugs with pipe thread sealant and
install the plugs.
Repeat this step for every drive hub.
Replace lubricant after the first 150h of use,
then every 1,000 h or yearly.
Figure 11-2 Swing Gearbox
1. Oil filler 2. Viewing port
3) Inspect oil level of swing gearbox
Remove the plug on the side and inspect
the oil level, as shown in Figure 11-2.
Result: Oil level shall be flush with viewing port
(2).
If necessary, add gear oil at the oil filler plug
until the oil level is flush with the bottom of

the viewing port, select gear oil by referring
to the Machine Specifications section.
Coat the plugs with pipe thread sealant and
install the plugs.
Replace lubricant after the first 50h of use, then
every 1,000 h or yearly.
1.3 Inspecting the Hydraulic
Oil And Filter
1) Inspect hydraulic oil level every 8 h or every
day.
△
!Caution: Perform this step when
the boom is in the retracted position.
Park the vehicle on the flat site. Fully retract
the boom.
Figure 11-3 Oil Level Sight Gaugel
Examine the oil level on the hydraulic oil
tank, i.e., level shall fall within the M range
shown as Figure 11-3, 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.
△
!Caution: 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.
1.4Regular maintenance
1) Maintenance work on a quarterly, annual
and biennial basis must be performed by
those who are trained and qualified in the
vehicle maintenance according to the
procedures specified in this manual.
2) If a machine has been idle for more than
three months, a quarterly maintenance
must be performed before it is operated.

Battery
Charging with matching
charger
1. Whether the battery is fully charged or not, if the
battery is not charged for a long time, the service life
of the battery will be shortened.
2. For a battery that has been fully charged, in
addition to the above maintenance measures, the
main power switch should be disconnected
whenever the battery will not be used for a long time
Add distilled water
If applicable check if the battery plates are covered
with electrolyte. If necessary, add distilled water to a
level just above the battery plates. Charge the
battery. Add water to 3mm/0.12in below the exhaust
well (plastic cover in the exhaust hole), and
