filter.
2) Remove the nuts at the bottom of the filter
cover with a wrench and remove the filter
cover.
3) Remove the filter element from the filter
cover.
4) Check the seal of filter cover and replace it
if necessary.
5) Install the new high-pressure filter element
and tighten it.
6) Scrub out any oil droplet that is splashed
out during installation.
7) Check the filter cover and the associated
elements to ensure no leakage.
1.12 Replacement of the air
filter of the hydraulic oil tank
Replace it every 500 hours or half a year, and
increase the number of times that perform this
step if the work environment is too dusty.
△
! Perform this step when the
engine is turned off.
1) Remove the filter element.
2) Scrub out the inside and tail cover of the
tank with a piece of damp cloth.
3) Install a new air filter element.
1.13 Check hydraulic oil level
Check it every 8 hours or every day.
It is crucial for the machine to keep the hydraulic
oil at a suitable oil level. The hydraulic oil at an
inappropriate level will damage the hydraulic
components. Through routine inspection, the
inspector can determine the change of hydraulic
oil level, which can indicate the problems of
hydraulic system.
△
! Notice: Perform this procedure
when the platform is in a folding state
and the engine is closed.
1) Park the vehicle on a flat ground. The
platform is in a folding state.
2) Check the oil pointer on the hydraulic oil
tank. When the fork frame is in the folding
state, the hydraulic oil level should be
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 fill the hydraulic oil if
necessary.

1.14 Inspect or replacement
of hydraulic oil
Replace the hydraulic oil every 2000 hours or
two years, whichever comes first.
△
! If the hydraulic oil is not replaced
during the two-year inspection, check
the hydraulic oil quarterly. Replace it
when the test is not qualified.
△
! Perform this step when the arm
lever is in the folding state.
△
! When removing the hose
assembly or couplers, the O-rings or
hose ends on the coupler must be
replaced and tightened to the specified
torque during installation.
Close two ball valves located on the hydraulic
oil tank (if the ball valve has been equipped).

Hazard of damage to components.
The engine cannot be started when the
ball valve of the hydraulic oil tank is
closed, otherwise the components will
be damaged. If the ball valve is closed,
remove the key from the key switch
and hang a warning sign on the
