equipment.
1) Remove oil drain plug, ring magnet, and oil
drain flange from the hydraulic oil tank.
2) Drain the hydraulic oil from the hydraulic oil
tank completely into a suitable container.
3) Disconnect the hose connected to the oil
tank and protect the hose coupler to
prevent foreign matter from entering.
4) Remove the fixed fasteners from hydraulic
oil tank.
5) Remove the hydraulic oil tank from the
equipment.
6) Remove the adsorption filter screen from
the hydraulic oil tank and clean it with a
mild volume.
7) Flush the inside of hydraulic oil tank with
mild solvent.
8) Clean the foreign matters adsorbed by ring
magnets.
9) Install adsorption filter screen.
10) Install oil drain plug. Ring magnet and oil
drain flange.
11) Install the hydraulic oil tank on the
equipment.
12) Install hose.
13) Fill the hydraulic oil to the hydraulic oil tank
until the liquid level is locked in the 1/2 - 2/3
of the liquid level meter (Short oil level
gauge) or
“LH” position of the liquid level
meter (long oil level gauge), and it is
forbidden to overflow.
14) Scrub off the hydraulic oil that may be
sprayed out.
15) Open the ball valve on the hydraulic oil
tank.
△
! Danger of damage to components,
after installing the hydraulic oil
tank, make sure to open two ball
valves of the hydraulic oil tank and
fill the pump with oil.
16) Check the functions of all machines through
an entire cycle and check for oil leakage.
17) Recheck the tank level after a cycle and
refuel to the specified position.
1.15 Check for the oil level in
the reducer
Check this step every 250 hours or a quarter.
The incorrect oil level in the reducer shall lead to
the reduction of equipment performance and
continuous use will result in damage to
components.
1) Drive the equipment rotating until a plug is
at the highest point, and the other is about
90 degrees from this one.
2) Remove the plug at 90 degrees and check
the oil level.
Result: The oil level shall be the same as the
bottom of the side plug hole.
3) When required, remove the upper plug and
refill oil until the oil level is the same as the
bottom of the side plug hole.
4) Apply the pipe thread sealant to the plug
and install the plug in the reducer.
5) Repeat this step for each reducer.

1.16 Replacement of the gear
oil of reducer
It is available in the first 50 hours, and it will be
replaced every 1000 hours or a year.
It is necessary to replace the gear oil of reducer
to maintain good equipment performance and
service life. Failure to replace the reducer oil
every year may result in reduced equipment
performance, and continuous use may result in
damage to components.
1) Select the reducer to be maintained, and
drive the equipment until one plug is at the
lowest point.
2) Remove the two plugs and drain the oil
(note to be drained) into the proper
container.
