[Inspection of the Lubricating Oil]

When the lubricating oil is insufficient, the engine will be seriously damaged. 

WARNING

Check the lubricating oil

 

level

 

before each  application. 

There is oil window on the right crankcase:
The oil surface should be at the scale line of  the oil window

(

Figure14

).

. 

During inspection, the longitudinal plane should be perpendicular to the level ground.

2.

 

When lubricating oil is insufficient, add moderate engine oil at SAE15W-40/SG

 

grade

 

or above until the scale line of the oil window.

 

3.

 

Install the screw plug of the oil filler and check oil leakage.

(7)Inspection, Adjustment and Lubrication of the Drive Chains

[Inspection and Lubrication of the Drive Chains]

The drive chain includes many mutually operated parts and its service life depends on good lubrication and 
appropriate adjustment. Negligence of chain maintenance and service will result in premature wear of the 
chains and sprocket wheels. Therefore, regular chain maintenance is necessary.
If the drive chain, small and large sprocket wheels reach their wear limit, it is necessary to replace them.

The inspection procedure is as follows:

1

. 

Switch to the neutral gear and the engine stops

(

take out the key

);

2

. 

Place the fingers on the

①

drive chain and swing the chain up and down. The normal amplitude range 

is 

:

between 10

～

20mm

;

3

. 

Check wear

 

conditions

 

of

 

various

 

chain

 

links

 

of

 

the

 

drive

 

chain

. 

If

 

there

 

is

 

missing

 

or

 

damage

 

or

 

over

 

wear

 

or

 

overlength

 

of

 

the

 

chain

 

link

, 

replace

 

such

 

chain

 

link

; 

4

. 

Check wear conditions of the large and small sprocket wheels. If the wheel teeth are seriously worn, 

missing or broken, replace

 

the

 

wheels.

When lubricating:

1

. 

Clean the drive chain, large and small sprocket wheels and add moderate engine oil to or spray 

lubricating oil on the cleaned drive chain, large and small sprocket wheels.
2

. 

Clean and lubricate one time for driving 500km

;

in the dusty areas, increase such maintenance frequency.

(10)Maintenance of Battery 

Notes 

The user must ensure the storage battery is fully charged, otherwise the battery will be damaged.
It is necessary to check the voltage of the battery with the voltmeter every week if you do not use 
the vehicle frequently. If the voltage of the battery is lower than 12.8V, it is necessary to

 

charge

 

the

 

battery

 

with

 

the

 

charger

 (

consult with

 

the

 

CFMOTO

 

Service

 

Station

 

or

 

authorized

 

local

 

dealer

). 

If the motorcycle is not used for over two weeks, it is necessary to charge the battery with the

 

charger

. 

Do not use automatic quick charger to charge the battery, otherwise the batterty will be 

overloaded or damaged.

Charger 

Contact the dealer for detailed description of the battery.

Charging the battery 

●Dismantle the battery from the

 

vehicle

（

refer to dismantling of the battery

）

●

Connect the charger lead and ensure that the charging current is 1/10A of the storage battery 

capacity,for example: given capacity is

：

For

 10

Ah

 

storage

 

battery

, 

the

 

charging

 

current

 

is

 1

Ah

.

When the storage battery is installed on the

 

vehicle

, 

ensure

 

the

 

power

 

of

 

the

 

storage

 

battery

 

is

 

full
