If your vehicle becomes immersed, major engine damage can result if the machine is not thoroughly 
inspected.  Take the vehicle to your dealer before starting the engine.

If it s impossible to take your ATV/Quadricycle to a dealer before starting it, follow the steps outlined below.

1. Move the ATV/Quadricycle to dry land or at the very least, to water below the footrests.
2. Remove the spark plug.
3. Check the air box and drain if water is present.
4. Loosen the carburetor drain screw.
5. Turn the engine over several times using the electric start.
6. Dry the spark plug and reinstall, or replace it with a new plug.
7. Tighten the carburetor drain screw.
9. Attempt to start the engine.  If necessary, repeat the drying procedure.
10. Take the ATV/Quadricycle to your dealer for service as soon as possible, whether you succeed in starting it 

or not.

If water has been ingested into the CVT, follow the procedure on page 104 for drying out the CVT 

and any damage which may occur may be the owner s responsibility.

Keeping your ATV/Quadricycle clean will not only improve its appearance but it can also extend the life of 
various components. With a few precautions, your ATV/Quadricycle can be cleaned much like an automobile.

The best and safest way to clean your ATV/Quadricycle is with a garden hose and a bucket 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.

 If warning and safety labels are damaged, contact your dealer for replacement.

Your ATV/Quadricycle does not recommend the use of a high pressure type car wash system for washing the 
ATV/Quadricycle. If a high pressure system is used, exercise extreme care to avoid water damage to the wheel 
bearings, transmission seals, body panels, brakes and warning labels.

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.

Your ATV/Quadricycle can be waxed with any non-abrasive automotive paste wax. Avoid the use of harsh 
cleaners since they can scratch the body finish.

Certain products, including insect repellants and chemicals, will damage plastic surfaces. Use caution when 
using these products near plastic surfaces.

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.

Make necessary repairs and then clean the ATV/Quadricycle thoroughly with mild soap and warm water to 
remove all dirt and grime.  Don t use harsh detergents or high pressure washers. Some detergents deteriorate 

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

Fill the fuel tank. Add Carbon Clean Fuel Treatment or Fuel Stabilizer. Follow the instructions on the container 
for the recommended amount. (Carbon clean will also reduce the possibility of bacterial growth in the fuel 
system.)  Allow 15-20 minutes of operation for the stabilizer to disperse through the fuel in the tank and 
carburetor and then drain the carburetor bowl.

Warm the engine and change the oil and filter.

Inspect and clean or replace the pre-cleaner and air filter.  Clean the air box and drain the sediment tube.

Inspect and clean or replace the breather filter.

Inspect the following fluid levels and change if necessary: front gear case; transmission; brake fluid (change 
every two years or as required if fluid looks dark or contaminated).

Remove the spark plug and add 2

3 tablespoons of 4 Synthetic 0W40 engine oil.  To access the plug hole, use 

a section of clear 1/4  hose and a small plastic squeeze bottle filled with the pre-measured amount of oil.

 Do this carefully! If you miss the plug hole, oil will drain from the spark plug cavity into the hole at 

the front of the cylinder head, and appear to be an oil leak.  Install the spark plug and pull the 
engine over slowly with the recoil starter. Oil will be forced in and around the piston rings and ring 
lands, coating the cylinder with a protective film of fresh oil.

If you choose not to use Fogging Oil, perform the following procedure.
1. Support the front end of the machine so the engine is level or tilted slightly rearward.
2. Remove the spark plug. Rotate the piston to BDC and pour approximately two ounces of oil into the cylinder.
3. Apply dielectric grease to the inside of the spark plug cap and install the cap onto the plug.
4. Turn the engine over several times to ensure coverage of piston rings, cylinder walls and crankshaft bearings.
5. Treat the fuel system with Carbon Clean.
6. If fuel system additive is not used, fuel tank, fuel lines, and carburetor should be completely drained of 

gasoline. To eliminate any fuel remaining in the carburetor, run the engine until it stops.

Inspect all cables and lubricate with Cable Lubricant. Follow lubrication guidelines in the maintenance section 
of the service or owner s manual to completely grease and lubricate the entire vehicle with All Season Grease.

Remove the battery from the vehicle and ensure that it's 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.

 

Set the tire pressure and safely support the ATV/Quadricycle with the tires 1

2 off the ground. Be sure the 

storage area is well ventilated, and cover the machine with a ATV/Quadricycle cover.

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

and may promote corrosion and oxidation.

Follow these procedures when transporting the vehicle.
1. Turn off the engine and remove the key to prevent loss during transporting.
2. Always place the transmission in park.
3. Be sure the fuel cap, oil cap and seat are installed correctly.
4. Always tie the frame of the ATV/Quadricycle to the transporting unit securely using suitable straps or rope.

Proper maintenance will protect chrome wheels from corrosion, preserve wheel life and ensure a

like new

appearance for many years.
1. Wash chrome rims frequently. Use a mild detergent to remove any salt, dirt, mud or grime. Never use abrasive 

cleaners on plated or painted surfaces.

2. Polish the clean chrome wheels periodically. Use an automotive grade chrome polish.
3. Routinely and liberally apply a weather resistant wax to each polished chrome wheel.

Choose a product suitable for chrome finishes. Read and follow the product labels and instructions.

4. Chrome wheels exposed to road salt ( or salt in the air in coastal areas ) are more susceptible to corrosion if 

not properly cleaned. Clean chrome wheels more often if they're exposed to salt or other corrosive elements.

If light rust is found on the chrome finish, use steel wool ( # 0000 

 OTT grade ) to remove it.  Gently rub the 

affected areas with the steel wool until the corrosion has been removed.  Clean and polish the wheel as outlined 
above.

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

Starting out going up a steep incline.

Driving at low RPM or low ground speed 
(at approximately 3-7 MPH).

Insufficient warm-up of ATV/Quadricycles 
exposed to low ambient temperatures.

Slow and easy clutch engagement.

Utility use/plowing snow, dirt, etc.

Towing/pushing at lowRPM/low ground 
speed.

Shift transmission to low range during loading of the

  

ATV/Quadricycle

  

to 

prevent belt burning.

When starting out on an incline, use low range or dismount the ATV/
Quadricycle (after first applying the park brake) and perform the K-turn as 
described on page 73.

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.

Warm the engine at least 5 minutes. With the transmission in park, advance 
the throttle to about 1/8 throttle in short bursts, 5 to 7 times.  The belt will 
become more flexible and prevent belt burning.

Use the throttle quickly and effectively for efficient engagement.
