Cleaning the ATV

Keeping your

 

ATV

 

clean will not only improve its appearance but it can also extend the life of various

 

components

.

With a

 

few precautions

,

your

 

ATV

 

can be cleaned much like an automobile

. 

Washing the ATV

The best and safest way to clean your

 

ATV

 

is with a garden hose and a pail of mild soap and water

. 

Use a professional type washing mitten

,

cleaning the upper body first and the lower parts last

.

Rinse

 

with water frequently and dry with a chamois to prevent water spots

. 

NOTE

If warning and safety labels are damaged

,

contact your dealer for replacement

. 

We do not recommend the use of a high pressure type car wash system for washing your

 

ATV

. 

If a

 

high pressure system is used

,

exercise extreme care to avoid water damage to the wheel bearings

, 

transmission seals

,

body panels

,

brakes

,

warning

 

labels

,

air filter intake system and electric system

, 

etc

.

Water is not allowed to enter into air filter

. 

NOTE

Grease all zerk fittings immediately after washing

,

and allow the vehicle to run for a while to evaporate

 

any water that may have entered the engine or exhaust system

. 

Clean & Storage

-131-

Waxing the ATV

Your ATV can be waxed with any non-abrasive automotive paste wax. Avoid the use of harsh 

cleaners since they can scratch the body finish. 

CAUTION

Certain products

,

including insect repellants and chemicals

,

will damage plastic surfaces

.

Use caution

 

when using these products near plastic surfaces

. 

CAUTION

Starting the engine during the storage period will disturb the protective film created by fogging and 

damage could occur. Never start the engine during the storage period. 

Clean the Exterior

Make necessary repairs and then clean the ATV thoroughly with mild soap and warm water to remove 

all dirt and grime.Do not use harsh detergents or high pressure washers.Some dete-rgents deteriorate

rubber parts.Use dish soap type cleaners only.High pressure washers may force water past seals. 

Clean & Storage

Oil and Filter

Warm the engine

,

then stop the engine and change the oil and filter

. 

CAUTION

When drain out fuel in fuel pipe and air pipe

,

if dashboard says only one grid of

 

fuel left

,

remove fuel

 

pump connector to drain out fuel in

 

fuel tank

,

or else

,

it may damage fuel pump

.    

Air Filter/ Air Box 

Inspect and clean or replace air filter

.

Clean the air box and drain the sediment tube

. 

Fluid Levels

Inspect the following levels and change if necessary

: 

front gear case

,

rear gear case

,

engine oil

, 

brake fluid

(

change every two years or as required if fluid looks dark or contaminated

),

coolant

. 

Clean & Storage

-133-

Fog the Engine 

Remove spark plug and add 15-20ml SAE 15W-40/SG engine oil. To access the plug hole, use a 
section of clean hose and a small plastic squeeze bottle filled with the pre-measured amount of oil. 

CAUTION

Do this carefully! If you miss the plug hole, oil will drain from the spark plug cavity, and appear to be 
an oil leak.

Remove plug cap and turn crankshaft to make engine run slowly. Oil will be forced in and around the 

piston, piston rings and coating the cylinder with a protective film of fresh oil.  

If you choose not to use the above way, perform the following procedure: 

1. Support the front end of the vehicle so the engine is level or tilted slightly rearward. 

2. Remove the spark plug, rotate the piston to BDC and pour approximately 15-20ml oil into cylinder. 

3. Remove plug cap and turn crankshaft to make engine rotate slowly. 

4. Turn engine several times to ensure the coverage of piston rings and cylinder walls. 

5. Treat the fuel system with Carbon Clean. 

6. If fuel system Carbon Clean is not used, fuel tank, fuel pipe and throttle body should be completely 

drained of gasoline. To eliminate any fuel remaining in the fuel pipe. 

Clean & Storage

-134-

Lubricate 

Inspect all cables and lubricate with Cable Lubricant. Follow lubrication guidelines in the maintenance 

section of the service manual to completely grease and lubricate the entire vehicle with All Season 

Grease. 

Battery Storage

Remove battery from the vehicle and ensure that it is fully charged before placing it in storage. 

Engine Anti-Freeze

Test engine coolant strength and change if necessary. Coolant should be replaced every two years. 

Storage Area/Covers

set the tires to specified air pressure and support the ATV with tires 30～40mm off the ground. Be sure 

the storage area s well ventilated and cover the machine with a ATV cover. 

Clean & Storage

-135-

NOTE

Do not use plastic or coated materials. They do not allow enough ventilation to prevent condensation, 

and may promote corrosion and oxidation. 

Transporting the ATV

     ATV can not be transported with stand up position, follow these procedures when transporting the 

vehicle: 

1.Turn off the engine and remove the key to prevent loss during transporting. 

2.Place the gear into any position except Park position, block front and rear wheels to prevent ATV run.

3. Never transport ATV with gear in Park position, or else engine will be damaged. 

4.Fix both the front and rear frame of ATV at the same time, prevent ATV slide or move during trans-

portation. 

5.Be sure the fuel cap, oil cap and seat are installed correctly.

Clean & Storage

Drive belt and cover problems

Possible Cause

Solution

Driving the ATV onto a pickup or tall
trailer in high range.

Shift transmission to low range during loading of the ATV 
to prevent belt burning.

Starting out going up a steep 
incline

.

When starting out on an incline, use low range or dismount 
the ATV (after first applying the park brake) and perform 

the K-turn as described on page 81

.

Driving at low RPM or low ground 
speed(at approximately 

5-10 km/h).

Drive at a higher speed or use low range more frequently. 
The use of low range is highly recommended for cooler 

CVT operating temperatures and longer component life.

Insuf fici ent  war m-up of ATV s exposed  
to

 

low ambient temperatures.

Warm the engine

 

before driving, the belt will

 

become more 

flexible and prevent belt burning

.

Slow and easy clutch engagement.

Use the throttle quickly and effectively for efficient 
engagement.

Towing/pushing at lowRPM/low 
ground

 

speed.

Use low range only.

Utility use/plowing snow, dirt, etc.

Use low range only.

Troubleshooting

-137-

Possible Cause

Solution

Stuck in mud or snow.

Shift the transmission to low range, and carefully use fast, 
aggressive thr ot tle ap pl icat ion to en ga ge clut ch. WAR RN ING : 
Excessive throttle

 

may cause loss of control and vehicle 

overturn.

Climbing over large objects from a
stopped position.

Shift the transmission to low range, and carefully use 
fast, brief, aggressive throttle application to engage 

clutch. Excessive throttle may cause loss of control and 

vehicle overturn.

Belt slippage from water or snow
ingestion into the CVT system.

Remove the CVT cover

，

drain the water from CVT.

Clutch malfunction.

Contact your dealer for inspection of clutch components.
