Add the following maintenance items in
addition to the monthly maintenance.
1. Replacement of brake fluid
① Park the forklift truck on a horizontal
road in the designated maintenance area,
lower the forks to the ground, engage the
hand brake handle securely, put the
transmission box in neutral and turn off the
engine.
② Take off the rubber dust cap on the drain
port, put the two ends of the prepared
transparent hose in the drain port and the
waste oil collection bottle respectively, and
then use a wrench to loosen the drain port
screw counterclockwise while another
person on the vehicle repeatedly presses the
brake pedal. During this process brake fluid
will be sprayed from the drain port, pay
attention to the level of the brake fluid
reservoir, and add new brake fluid as the
fluid level drops. Tighten the screws of the
drain port once clear brake fluid flows out.
③ Repeatedly press the brake pedal to the
bottom and hold it, while the person under
the forklift loosens the screws of drain port,
tighten the screws after clear brake fluid
comes out and then asks the person on the
forklift to release the brake pedal. Carry out
the above operation several times until there
are no air bubbles in the released brake fluid.
Check the fluid level in the brake fluid
reservoir and add new brake fluid as the
fluid level drops.
Caution
Prevent dust and water from mixing
when adding brake fluid.
Brake fluid is toxic and corrosive and
should be rinsed off if you are exposed to
it.
2. Lubrication of the steering wheel locking
device
Apply lubricating grease to the steering wheel
locking device.
3. Check, clean and replace the hydraulic
return oil filter, breathing apparatus and filter
screen
Park the forklift truck on a horizontal road,
lower the forks to the ground, tilt the mast
back, engage the handbrake firmly, put the
transmission box in neutral and turn off the
engine.
① Loosen the bolts on the upper cover
assembly of the hydraulic oil reservoir.
② Remove the return oil filter from the upper
cover.
③ Install the new return oil filter by hand.
④ Remove the filter screen from the oil
reservoir.
⑤ Install a new filter screen by hand.
⑥ Install the upper cover of the oil reservoir
and tighten the bolts.
⑦ Remove the breathing apparatus, clean and
dry it with a clean and non-flammable cleaning
agent and several separate air filter screens.
⑧ Install the breathing apparatus.
⑨ Start the engine and operate the hydraulic
system so that the hydraulic oil fills the entire
system. Check for leaks.
⑩ Turn off the engine to check the oil level.
Retract all cylinder rods so that the oil level
remains between the scales of the dipstick.
4. Change the hydrodynamic transmission ATF
See the Change the hydrodynamic transmission
ATF in the Monthly Maintenance Sheet
5. Check, clean and replace the fuel filter
Caution
In dusty or dirty operating
environments, it is necessary to clean
the fuel filter once a month and replace
it every six months.
① Remove the fuel filter assembly.
② Remove the sensor assembly.
③ Install the existing sensor assembly and
apply a little clean fuel to the filter sealing
point before installing a new one.
