Notice on use gasoline and engine oil

Gasoline

Better to use the lead free gasoline. The octane number of gasoline

should be over 90. If the engine got some sound like knocking, the

reason maybe is using unqualified RQ level fuel, should change it.

Using the lead free gasoline is good for the spark plug.

Engine oil

0.9L engine oil should be taken. Please use the engine oil special for

4-stroke (4T). Choose the SE level and SD level that sort by API.

OPERATIONS

Change of rotate speed of engine Engine oil number: SAE10W-40 or SAE15W-40 is recommended, and

SAE10W-30 should be used if the temperature is below 5°C. If that
kind engine oil is not easy to be found, please choose the substitute
follow the parameter as below shows:

The rotate speed of the engine should be changed frequently, and not to

remain at one speed. This is good to the run in pe riod of new one: to get

average pressure for the components and cool them when pressure

reducing. By varying the speed frequently, put some applicable burthen

to each component and make them combined with each other. But don't

put too much burthen.

Avoid low rotate speed
The components will only be smooth because of whetting during low

rotate speed of engine. One should change different speed up the engine

within the maximum rotate speed. But within the first 1500Km for a

new scooter, don't rotate the throttle to maximum position, and don’t

rotate the throttle suddenly.

Cycle the engine oil before driving
Gear oil After started the engine in hot or cool situation, don't drive immediately,

let the engine has enough time for idle speed and let the engine oil

reach to each important part of the component inside the engine.

Please use SAE80W90 gear oil.

Run in period of new scooter First maintenance

A perfect run in period of a new scooter is very important to extend the
life of the scooter and exert perfect perfo rmance. The following is the
correct method during running in period of new one:

The maintenance within the first 1000Km is the most important job for

a scooter. After run in period of new one, all the engine parts and other

parts are combined well with each other. Then one should adjust well

the components, fasten the screw and change the used engine oil. Well

execution of the maintenance within the first 1000Km guarantees a

longer life and a better performance of the scooter .

Maximum rotate speed

Maximum rotate speed of the engine during the run in period of new
one should be as following:

9

Run in distance (Km) 0-150 151-300 301-800 801-1500

Speed of scooter

(Km/h)

30 40 50 60

The maximum speed should not be over 80km/h in the first 3000Km .

Note: The maintenance within the first 1000Km should be
executed accordingly to the checking and maintaining chapter,
and one should pay special attention to the words: "Warning" &
"

"

OPERATIONS

Engine oil Check to ensure that the oil level is norma l.

Fuel throttle

Check to ensure a proper play for the
throttle cable and throttle grip;
Check to ensure the turning up is free and
the turning back down can be abruptl y back
down.

W

arning: If this is your first time to drive this type of scooter,

you are suggested to be practice in a safe and non-crowded field
until you are fully familiar with control and operation of this
motorcycle. One-hand driving is extremely dangerous. Keep
both hands firmly on the handlebars and both feet on the
footrests. Under no circumstance should both hands be removed
from the handlebars.

W

arning: Don’t reduce the speed when you are making a

cornering. Slow down to a safe speed before cornering.
When the road surface is wet or slippery, you must reduce
speed. Obey the speed limit and traffic regulations.

Starting the engine

Insert the key into the ignition switch and turn it clockwise to

position .

1. Electric-start

Fully pull in the brake lever, and press down the start button , the

engine will be started.

Notes: Release the start button immediately after starting is
successful, otherwise harm is done to the engine.
If the engine cannot be started after pressing the start button for 5
seconds, you should postpone it for 10 seconds before try it once
again.
If the engine can not be started even after pressing the start button 2
or 3 times, please turn the throttle grip up by 1/8 to 1/4 circle while
try it once again.
Don't keep the starting motor working constantly, which causes
battery power consumed too much and harm is done to the starting
motor.

OPERATIONS

Driving on a slope 2.Start the e ngine by the kick-start pedal

When battery is low or start the engine in the first time, please start the
engine by the kick-start pedal.

1. When climbing a steep slope, the scooter may slow down as a result

of insufficient power. In this case, you should turn throttle grip toward

yourself to increase fuel for the forwarding power. (a) Turn the ignition switch to .
(b) Press down the kick-start pedal by your foot with force. 2. When driving down a steep slope, you may use the resistance by pull

the brake levers. Be carefully, use both brake levers at the same time.

11

W

arning: Never start the engine in a room that is of poor

ventilation or no ventilation at all. Never let the engine run
when there is no one taking care of it.

Braking and Parking

1. Turn the throttle grip away from yourself to close the throttle

completely.

Caution: Do not let the engine run at idle alone too long time if
you don't drive it away. Idling alone too long time is liable to
make the engine overheated and damage internal engine
components.

2. Simultaneously apply the front and rear brakes evenly.

3. Before stopping, take your braking distance carefully. It takes two

times of braking distance in the rainy or snow weather.

4. Turn ignition key to position to shut the engine down, and turn the

handlebar left, also push and turn ignition key to “LOCK” position to

lock the steering stem for safety. Remove the ignition key from the

switch.

Starting to drive on

Turn the throttle grip toward yourself and release the brake lever
gradually at the same time, then the scooter will start moving forward.
The speed can be adjusted by rotating the right handle grip (throttle
grip), which can be accelerated by turning the throttle grip toward
yourself slowly and can be decelerated by returning the throttle grip
clockwise quickly.

Warning: The fast the speed, the longer the braking distance. Be
sure you have sufficient braking distance from the vehicle or object
ahead of you so that you can stop the scooter safely.
Inexperienced drivers tend to use the rear brake only. This will
quicken the wear of brake devices and increase the braking distance.

Before you start to drive on, please give the starting signal by turning
signal light wink and be sure safety to drive on.

Using only the front or the rear brake is dangerous. It is liable to
result in a skidding and loss of control. Applying the brakes gently
and with great care when driving on a wet or slippery road. Abrupt
braking on a slippery or uneven road is extremely dangerous. It is
likely to result in loss of control of the scooter.

Caution: You should never increase the speed to one that is
indicated by the red zone in the tachometer that pu t yourself in
risk. Don’t rotating the throttle grip suddenly that will causes the
scooter jump suddenly.

MAINTENANCE

Spark plug

Air cleaner

1. After the initial 1,000 km and every Air cleaner is located under the seat and in the front of luggage
cabinet. The core of air cleaner for this scooter is made of filter
paper and sponge. If it is blocked, the resistance of air intake is
increased but the output power is decreased, and also fuel
consumption will be increased. For this reason, t he core should be
inspected and cleaned following the procedures below after every
3,000Km. Clean and r eplace the core more f requently if th e scooter
is used in the dusty circumstances. Don't wait until the time for
maintenance is actually due.

3,000 km after that, clean the carbon
deposit on the spark plug with a wire
brush or a plug cleaner and readjust
the gap to 0.6-0.7mm with a thic kness

gauge.

2. Replace the spark plug with a new

one after every 6,000 km.

3. At the same time as you are cleaning

the carbon deposit on the spar k plug,
you should observe the color on the porcelain tip of the spark plug,
Light gray or brown color should be the color for a spark plug that
works properly under this circum stance.

Standard spark plug:

NGK, type A7TC or type A7RTC.

Its disassembling order:

1. Open and pull up on the seat.

2. Loosen the screws of the top cover of air
cleaner, and take off the paper-filter c ore.

3. Loosen the screws on the inside fence,
open the fence and take off the sponges in
front of air intake pipe.

How to clean the core of air cleaner

1. Use high pressure air to blow
and clean the paper-filter core.

2. Pour the non-inflammable
detergent into a basin of proper
size container and immerse the
sponges into detergent for
cleaning.

Caution: Never start engine until core of air cleaner is assembled.

Caution:

●Spark plug used in this scooter is chosen with care and is good
for most of the working conditions. If the color of the spark plug is
different from that of the standard one, it's better that you have a
discussion with the dealer before replacing it with a plug of
different heat resistance. Because unsuitable sparks plug will
seriously damage the engine.

●Spark plug should not be tighten excessively or tightened when
the treads are not properly engaged in case treads on crankcase
cover be damaged. When removing the spark plug, make sure not
to allow any dirt into the engine through the plughole.

Brake system

Disc brakes are appl ied to the front and rear wheel of this scooter.
The brakes should be inspected after the initial 1,000km and each
3,000km after that.

Check the front/rear disc brake lever for res istance when squeezed.
If there is resistance when squeezed, that shows the disc brake
system is working normally. If there is lose of resistance when
squeezed, that shows the disc brake system function lost.

Filling brake fluid to top brake fluid tank.

The top brake fluid tank is also called as hydraulic cylinder comp.

When brake fluid is les s or no in the disc brake sys tem, that brake
will be not working any more.
Check the brake fluid level of top
brake fluid tank by the brake
fluid level checking window on
the handlebars. If there is no
brake fluid, loosen two screws
on the cover of top brake fluid
tank and open the cover to fill the bra ke fluid.

Drain out the air from brake system

Disc brake system is not working and the brake lever is lost of
resistance when there is air in the
brake system.

1. Try to squeeze the brake lever,
and hold on the brake lever when
feeling the resistance.

2. Loosen the drain air out screw “R”
on the caliper counterclockwise, and
drain out air from the brake system.

3. Reinstall that screw “R” tightly after air had drained out, loosen

A. on-inflammable detergent
B. engine oil

W

arning: Only use DOT3 type brake fluid to this scooter. Don’t

mix with other types of brake fluid since that will damage the
scooter brake system. Onl y use fresh brake f luid since the us ed
brake fluid often included with water and air, which will also
damage the brake system. If filling the brake fluid too often,
there may be leak in the brake system, check hydraulic hose and
take the scooter to service shop soon.

Caution: If there is break in the core, it should be replaced wit h
new one. Never use easy-inflammable fuel (gasoline etc.) as
cleaning detergent.

MAINTENANCE

Tire pressure

the brake lever accordingly.

4. Repeat step 1 to step 3, until the resistan ce is large enough when

squeezing the brake lever.

Insufficient tire p ressure quickens wear to tires and strongly af fects
the riding stability. Insufficient pressure causes difficult steering
control but excessive i nflation leads to less contact area of the t ire
with the ground so as to slip and lose control. Keep tire pressure
within the required range. Adjust tire pressure when the tire is in a

cold state, which is 200kpa/225kpa for front/rear tire.

5. Cover the drain air out screw “R” with dust-proof cap after brake

system adjustment finished.

Replace brake pads

When howling sound comes from brake disc plate, or some concave
nicks shown on th e brake disc plate, the brake pads in side caliper
must be replaced at once.

Tread

Both pads must be rep laced at t he same t ime, even o nly one i s worn
to the limit.

Tires

Check the tire pressure and tread depth when applying periodic
maintenance in a view to maintain maximum safety performance and
longer service time. Gi ve i rr egul ar ch ecks to t hem ap art fr om rou ti ne

servicing. Carefully check to escape fro m nail or glass on the tires.

Always replace tires when there is visible damage, such as brok en
tread or gashes in the tire wall.

Driving a scooter with excessively
worn tires decreases riding stability and
leads to loss of control. Replace the front
tire when its tread depth decreases to
less than 1.6mm and the rear tire
when its tread depth is less than 2mm.

Specifications of tires (front/rear) used in this scooter is 130/60-13

Battery

Maintenance free battery is used
