[Battery Model Number]

[Inspection and Maintenance of the Battery]

When dismantling, first dismantle the lead of negative electrode
It is necessary to clean the terminals of positive electrode

 

and negative electrode

of the battery on a 

regular basis. When installing, first install the lead

 

of

 

the

 

positive

 

electrode

 

and then the lead of the 

negative electrode

and ensure that the terminals of the positive and negative electrodes are tight

; 

the

 

positive and negative electrodes cannot be reversely connected.
When replacing the battery, it is necessary to use the battery with the same model number and specification.

The Battery Model Number of the vehicle is

:

YTX7L-BS

 ，

the capacity is

:

12V 6Ah. It is under the seat

.

The vehicle is equipped with maintenance-free battery, so it is not necessary to inspect the electrolyte 
quantity or add distilled water. Once the electrolyte is poured into the storage battery, the seal cannot be 
taken down. However,

 

to ensure the best service life of the storage battery, it is necessary to charge the 

storage battery appropriately to ensure sufficient power for starting the motor. When the motorcycle is 
used frequently, the charging system of the motorcycle will charge the storage battery automatically. If the 
motorcycle is used occassionally or for a short period, the battery power is insufficient. The storage battery

 

will

 

produce

 

self

-

discharge

, 

the

 

discharge

 

speed

 

of

 

which

 

varies

 

according

 

to

 

type

 

of

 

the

 

battery

 

and

 

environmental

 

temperature

.

When the motorcycle is not used for a long time

, 

it

 

is

 

necessary

 

to

 

take

 

down

 

the

 

storage battery from the 

motorcycle for storage and regularly charge the battery

[Fuse Replacement]

The rated current of the starting relay fuse is 20A and It is on the starting relay behind the battery.
There is one spare fuse below the rubber sheath of the  Starting relay

;

The fuse box is in the front part underneath the seat cushion

，

The function is as shown in Figure 24.

If the fuse is burned frequently, it means the circuit System is short or overloaded and it is necessary to send 
It to 

“

CFMOTO

 

Service

 

Station

”

for repair.              

                            

When replacing the fuse, dismantle the old fuse and install the new one and connect it.

WARNING

Before inspection or replacement of fuse, it is necessary to turn off the ignition switch and 
electric switches in case of short circuit.
Never use fuse that is inconsistent with the rated current, otherwise the electric system of 
the vehicle will be damaged or cause fire. Or during nighttime or driving, it might result in 
failed turning on of the lights or engine failure.

(11) Maintenance Instructions to Water-cooling System 

[Cooling System]

The radiator is in the front of the engine. You should regularly remove dust and dirt from the radiator 
according to the conditions of the driving roads.

Coolant Type

Notes：

Check the Volume of the Coolant 

1.Make the longitudinal plane of the motorcycle be perpendicular  to the level ground during inspection

;

2.

 

Check level of the coolant when the engines is cooling down

.

3. The coolant should be between the upper and lower scale lines.

- 51-

It should only adopt high-qualitly ethylene glycol based and corrosion inhibitor-inclusive antifreeze agent, 
which is especially for alumnium engine.
The cooling system of the motorcycle includes 50% antifreeze agent and 50% water before delivery.

It should only adopt high-qualitly ethylene glycol based and corrosion inhibitor-inclusive 
antifreeze agent, which is especially for alumnium engine.
The cooling system of the motorcycle includes 50% antifreeze agent and 50% water before delivery.

for replacement and repair.

(12)Vehicle Cleaning and Storage

[Vehicle Cleaning]

WARNING

- 53-

Clean the motorcycle regularly in order to detect damage, wear or leakage

 

problems

 

timely

.

When cleaning, flush with clean water. After cleaning, wipe dry the motorcycle and start the engine to run 
for several minutes

; 

lubricate

 

the

 

drive

 

chain

 

with

 

the

 

lubricating

 

oil

; 

before

 

road

 

driving

, 

check

 

brake

 

and

 

the

 

front

 

and

 

rear

 

brakes must be normal.

1. Parts cannot be cleaned by high pressure water: ignition switch, electric switch, 
instrument, electric parts, battery, air filter, wheel hub, exhaust pipe outlet, the lower part 
of the fuel tank and so on.
2. After cleaning, the brake performance might be reduced. Thus, it is necessary to test the 
motorcycle and inspect it for adjustment and restoration before use.

[Vehicle Storage]

[Vehicle Use after Storage]

-5 4-

After use, the user should store the motorcycle in dry, good-ventilated safe area with small temperature 
difference.
For long-term storage

 (

over 30 days)

, 

it

 

is

 

necessary

 

to

 

carry

 

out

 

indispensable

 

repair

 

before

 

storing

 

the

 

motorcycle

; 

otherwise

, 

repair

 

problems

 

might

 

be

 

forgotten

 

after

 

storage

.

For long-term storage

 (

over 30 days)

, 

besides

 

the above maintenance, it is necessary to implement the 

following

:

1.

 

Clean and dry the motorcycle and wax the whole painted surface

;

2.

 

Drain the fuel in the fuel tank and inject anti-rust agent inside the fuel tank

;

3. Take down the spark plug and inject a few lubricating oil

(

15

～

20 ml

)

to the cylinder

;

and then install the 

spark plug

;

4.

 

Dismantle the spark plug and store it in good-ventilated, dry, cool area without direct sunlight

; 

5.

 

Inflate the tire until reaching specified pressure and place the motorcycle on the cushion block to make 

the front and rear wheels get off the ground

;

6.

 

Cover the motorcycle with the strong air permeable material and store it in dry, good-ventilated safe area 

with small temperature difference.

1.

 

Take down the motorcycle covering and clean the motorcycle.

2. Check voltage of the storage battery. If the voltage is below 12.8V, carry out low-speed charging to 
supplement the battery power and then install storage battery.
3. Remove the anti-rust agent inside the fuel tank and add fresh fuel.
4. Try to ride the motorcycle in the safety place and check whether the motorcycle performance is normal.

(13) Vehicle Service Life and Vehicle Handling

[Vehicle Service Life]

For vehicle service life, implement according to the regulations of the traffic administration department or 
local vehicle administration station.

[Vehicle Handling]

- 55-

1.

 

Handling of waste lubricating oil: the waste lubricating oil repaced by the motorcycle should be stored 

in the plastic cask and submitted to the company for handling. The user cannot discharge the waste 
lubricating oil at will, otherwise, site, soil, water source and so on will be damaged.

  

2

. 

Handling of the waste storage battery, bulb, appearance parts, filter element, tire, iron parts, alumnium 

parts and so on: these scrapped parts shall be classified into the waste bin as the waste. The user should not 
discard such waste at will and cannot discard the dilute sulphuric acid of the storage battery, which will 
cause injury to people or pollution to environment.
3.

 

After scrapping, handle the vehicle according to the regulations of the traffic administration department 

or local vehicle administration station.
