Air Filter

Air Filter Maintenance
To maintain the highest performance from your
engine and to reduce excessive wear that could
cause engine failure the engine requires a
continuous flow of clean air. Air is taken into the
engine through an air filter to clean the air prior
to mixing it with fuel and oil in the carburetor.
During normal operation the filter
accumulates dirt from the air and will need to
be cleaned to maintain the proper air flow.
The filter should be cleaned every 30 days,
more often if you ride in a dusty or dirty
environment and the element should be
replaced every year.
The air filter box is located on the left side of the
engine under the front fender. It is a black box
about 6" square and is attached to the
crankcase with two bolts and the carburetor by
a tube.
To clean the filter
Remove the air filter box cover.
Remove the filter element from the air box.
Wash the element in a non-flammable solvent
such as Air-Filter cleaner from your local auto
parts dealer.
1. Dry the element completely before
continuing.
2. Soak the element in clean engine oil until
completely saturated.
3. Squeeze out the excess oil until the
element does not drip any oil.
4. Allow the element to dry then reinstall the
element and cover.

Braking Systems

Your ATV unit is equipped with dual front
mechanical drum brakes and a rear hydraulic disc
brake. The front brakes are applied by squeezing
the brake lever on the right-handle bar, while the
rear brake is applied by squeezing the brake lever
on the left-handle bar.
Proper maintenance of the brake system is a
necessary part of safe operation of your unit. The
brake systems should be inspected and tested
before each riding session.
Front Brake System Inspection
Visually inspect the brake cables for any signs of
wear. Inspect the cables for frays and kinks that
inhibit the free movement of the cable. Replace
frayed or kinked cable before operating your unit.
Inspect the cables for rust or corrosion. Replace any
brake cable that show signs of corrosion as this
could cause a reduction in cable strength that can
lead to the cable breaking.
Inspect the brake arm, spring, rod and fastener for
signs of wear or damage. Operate the brake lever
while watching the brake mechanism for proper
operation. Tighten, repair or replace parts as needed
to insure safe brake operation. Clean any build-up of
mud or debris from the brake mechanism.
The brakes are equipped with a wear indicator to
alert you when your brake shoes need replacing.
Apply light pressure to the brake lever and slowly
push the unit forward. If you hear a high pitched
metallic scraping sound, you need to replace your
brake shoes. The minimum shoe lining thickness is
1.5mm.
