1.1 SAFETY
GASOLINE

Gasoline is extremely flammable and is explosive under certain condition. Do

not smoke or allow sparks or flames in your work area.

●

CARBON MONOXIDE

Never run the engine in a closed area. The exhaust contains poisonous carbon
monoxide gas that may cause loss of consciousness and lead to death.

●

BATTERY ELECTROLYTE

The battery electrolyte contains sulfuric acid. Protect your eyes, skin and
clothing. If you contact it, flush thoroughly with water and call a doctor if
electrolyte gets in your eyes.

●

HOT PARTS

Engine and exhaust pipe become very hot and remain hot for one hour after the
engine is run. Wear insulated gloves before handling these parts.

●

USED ENGINE/GEAR OIL

Used engine oil and gear oil may cause skin disease if repeatedly contact with
the skin for long periods.

Keep out of reach of children.

2.3 FUEL TUBE

Inspect the fuel lines for deterioration,
damaging or leakage and replace if necessary.

2.4 THROTTLE OPERATION

Inspect for smooth throttle lever full opening and
automatic full closing in all steering positions.
Inspect if there is no deterioration, damage or kink
in the throttle cable, replace it if necessary.

Check the throttle lever, free play is 2

————

5 mm at the
tip of the throttle lever.
Disconnect the throttle cable at the upper end.
Lubricate the cable with commercially lubricant to
prevent premature wear.

2.5 THROTTLE CABLE ADJUSTMENT

Slide the rubber cap of the adjuster off the throttle
Housing, loosen the lock nut and adjust the free play
of the throttle lever by turning the adjuster on
the throttle housing. Inspect the free play of the
throttle lever.

2.6 AIR CLEANER

Please remove the four hooks, and then disassemble
two screws inside the air cleaner case.
Pull out the air filter element from the air cleaner case.
Washing the element in non-flammable solvent, squeeze
out the solvent thoroughly.
Let it dry.

component

into air cleaner in the reverse

order of removal.

Note: for more detail please check chapter 5-10

2.7 SPARK PLUG

This spark plug is located at the front of the engine.
Disconnect the spark plug cap and unscrew
the spark plug.
Check the condition of spark plug electrodes wear.
Change a new spark plug if the electrodes and
insulator tip appear unusually fouled or burned.
Discard the spark plug if there is apparent wear
if the insulator is cracked or chipped.

The spark plug gap shall keep in 0.6-0.8mm

With the sealing washer attached, thread the
spark plug in by hand to prevent crosses threading.

Tighten the spark plug with 12-19 N.m

2.8 IDLE SPEED

Connect an engine speed meter.
Warm up the engine, 10 minutes are enough.
Turn the idle-speed adjust screw B on the carburetor
to obtain the idle speed. “Turn in” (clockwise) will
get higher speed. “Turn out” (counter clockwise) will
get lower speed.

IDLE SPEED: 1500±100 rpm

2.9 BRAKE SYSTEM

Inspect the front brake lever and cable for excessive
play or other damage.
Replace or repair if necessary.
Measure the free play of the brake lever at the end of the
brake lever.

The standard of free play is 5-15 mm.

The parking brake is shown on the picture. The position
of parking Off is on the left side. Turn parking brake to
right side is parking on

Brake handle

Parking Brake

10

Inspect the rear brake lever and cable for excessive
play or other damage.
Replace or repair if necessary.
Measure the free play of the rear brake lever at the
end of the lever.

The standard is 5-15 mm.

The second method to adjust brake level is under the
driver seat and rear brake component.
Because the brake system is different, ones need to adjust it
to reach a proper brake level.

2.10 WHEELS AND TIRES

Inspect the tire surfaces for cuts, nails or other
sharp objects.
Check the each tire surface at cold tire condition.

*The standard of tire pressure is 8(0,6до1,0)

psi ( kgf/cm2)

2.11 STEERING SYSTEM

Check the free play of the steering shaft with the front
wheels, turned straight ahead.
When there is excessive play, inspect the tie-rod,
kingpin bushing and ball joint.

Parking BRAKE Adjustabie nut

11

STEERING SHAFT HOLDER BUSHING

Remove the front fender first.
Remove the steering shaft holder and check the
steering shaft bushing for wears or damage.
If the bushing is worn or damaged, please change a new
one.
Grease the steering shaft bushing and install the parts
in the reverse order of removal.

Torque: steering shaft holder bolt: 33 N.m (24 lbf.ft)

2.12 TOE-IN

Keep the vehicle on level ground and the front
wheels facing straight ahead.
Mark the centers of the tires to indicate the axle
center height.
Measure the distance between the marks.

Carefully to move the vehicle back, let the wheels
turn 180 degree, so the marks on the tires are aligned
with the axle center height.
Measure the distance between the marks.
Calculate the difference in the front and rear
measurements.

Toe-in: 5±10mm

12

If the toe-in is out of standard, adjust it by changing
the length of the tie-rods equally by turning the tie-rod
while holding the ball joint.
Tighten the lock nuts.

Torque: 35-43 N.m

General Information

Warning

Gasoline is a low ignition point and explosive materials, so always work in
a well-ventilated place and strictly prohibit flame when working with
gasoline.

●●●●

Do not bend off throttle cable. Damaged throttle cable will make

unstable drive-ability.

●●●●

When disassembling fuel system parts, pay attention to O-ring

position, replace with new one as re-assembly

●●●●

There is a drain screw in the float chamber for draining residual

gasoline.
