Rear view mirror 

If the scooter will not be ridden for a long time, the battery should be 
removed and place at a cold, dark and well ventilated space. The 
battery should be fully charged before returning to the scooter.

objects can be seen clearly. Clean dirty on the mirror and replace the 
broken parts. 

 

Fuse 

 

Storage 

The fuse cartridge is put beside the battery by the strap. The rated 
current for the fuse is 15 ampere. When there is a sudden flameout or 
circuit failure, check fuse first. 

Following the instruction below to maintain your scooter in good 
condition if you want to keep it for long-time storage. 

 
 
 
 
 

1. Replace the engine oil. 

Caution: 

Pay attention to select a fuse with a correct rating of 

current. Do not use aluminum or iron wire as substitute. If the 
fuse often burns within a short time of running, it indicates 
something is wrong with the electrical system. Contact a local 
dealer to inspect it soon. 

2. Discharge all the fuel in the fuel tank and the carburetor. Fill 
anti-rust oil into the fuel tank. 
3. Take off the spark plug and fill 15-20ml of pure engine oil into 
the cylinder. Turn the key to        position. Kick the starting pedal for 
several times and then put the spark plug back, keeping its wire 
touching the ground. 

 

Lights

lever, be sure the stop light will be on. 

4. Uninstall the battery and store it in a ventilating place, and is 
suggested to charge once a month. 

2. Turn ignition switch on, and push the turning signal light button, 
be sure the front/rear turning lights is working normally. 

5. Clean the scooter and apply anti-rust oil to the iron parts. 
6. Inflate the tire and stand up the scooter, keep the wheels away 
from the ground. 

3. Check the headlight and position light working normally. 
4. Check the indicating light on meter working normally. 

7. Put cover on the scooter. 

5. Clean dirty on the covers of all lights and replace the broken parts. 

 

 

Bulbs 

Ratings of all bulbs are as listed in the Specification Parameters. Use 
bulbs of same ratings when replacing. Different ratings may cause an 
overload to the wiring system and an earlier failure of the bulbs. 

 

 
 
 

Warning: 

Keep the fuel away from smoke or fire and flame out 

the engine while discharging or refilling. If the scooter will be 
stored over half a month, should discharge fuel in carburetor.
