AIR CLEANER
In case of driving in dusty environment, air filter shall be cleaned regularly. It is of great possibility to
accelerate wear to engine if there is not filtering element or worn filtering element is used. So, please keep air
filter under good conditions all the time. If vehicle is used in dusty area, inspect more frequently than specified in
MAINTENANCE SCHEDULE.
If the air cleaner is clogged with dust,intake resistance will be increased,with a resultant decrease in power
output and an increase in fuel consumption. never remove or modify any component in the air filter housing. The
engine management system is calibrated to operate specifically with these components. Otherwise, engine
performance degradation or damage can occur.Check and clean the air cleaner element in the following manner:
Open the tiltable seat
Remove the nuts at both ends
of the empty filter

2.PERIODIC MAINTENANCE
2-4
Remove bolt and filter element
Blow low pressure compressed air on filter
element to clean it.
Properly reinstall removed parts in the reverse order of their removal. pay attention to the seal gasket of air filter
housing is not skew.
CAUTION
1.If liquid /deposits are found, squeeze and dry the foam filter. Replace filter element if damaged.
2.Do not start engine if liquid or deposit are found. If there is oil in the air filter housing, check engine oil level.
Oil level may be too high.
3.Inspect the air cleaner element for tears, a torn element must be replaced.

2.PERIODIC MAINTENANCE

THROTTLE CABLE PLAY
Before starting the engine, check the gas pedal to be sure it is operating correctly. Make sure the gas pedal fully
returns to the idleposition as soon as it is released.
Check the free play and adjust if needed. Press the throttle to make sure it moves smoothly without sticking and
snaps back automatically when it is released Check to see that the gas pedal operates correctly. It must operate
smoothly and fully spring back to the idle position when released. Have a dealer repair if necessary for proper
operation.
Check throttle pedal free play: 3 - 5mm
In case of out of range: → adjustment
Loose throttle cable (bracing cable).Turn adjuster to
adjust free play of throttle pedal.
After adjustment, tighten nut.
If free play after adjustment cannot reach designated
requirement or there is viscosity for throttle valve,
replace it with new throttle cable.

BRAKING SYSTEM
Check to see if any brake fluid is leaking out of the pipe joints or the brake fluid reservoir. Apply the brakes
firmly for one minute. If there is any leakage, have the vehicle inspected by an authorized dealer.
Test the brakes at slow speed after starting out to make sure they are working properly. If the brakes do not
provide proper braking performance, inspect the brake system. If needed, have the vehicle inspected by an
authorized dealer.
Brake fluid level
Check the brake fluid level by observing the lower
limit line on the brake fluid reservoir.
When the brake fluid level is below the lower edge of
sightglass, replenish with brake fluid DOT4.

WHEELS
Lift wheels up at horizontal position and ensure no
load to each wheel.
Shake wheels to left and right to see whether their
connecting parts are installed tightly and check whether
they can be swung.
No adequate tightening: → tightening
Swing: → replace rocker arm
Tire pressure
Improper tire pressure will lower comfort of operation and driving and may lead to wear to side edges of tires.

SUSPENSION SYSTEM
Lubricate both suspension arms with lithium-soap based grease. There are two grease fittings on each suspension
arm. Check operation and for leakage.
Grease fitting location of front suspension arms.
Lubricate the chain with lubricating oil.
CHAIN MAINTENANCE
The new chain is too long or extended after use, it is difficult to adjust, the chain link can be removed
according to the situation, but it must be an even number. The link should pass through the back of the chain, and
the opening of the locking piece should be in the opposite direction of rotation.
After the sprocket wears seriously, the new sprocket and new chain should be replaced at the same time to
ensure good meshing. It is not possible to replace new chains or sprockets alone. Otherwise, it will cause poor
meshing and accelerate the wear of the new chain or new sprocket.
The old chain can not be mixed with some new chains, otherwise it will easily cause impact in the
transmission and break the chain.
The chain should be filled with lubricant in time. Lubricating oil must enter the matching gap between the
roller and the inner sleeve to improve working conditions and reduce wear.
When the vehicle is stored for a long time, the chain should be removed and cleaned with kerosene or diesel,
then coated with engine oil or butter and stored in a dry place to prevent corrosion.
