DO NOT allow the engine to operate with
an empty oil tank. Doing so will result in
extensive damage to your engine. This
damage is not covered under the warranty.
Check the oil tank level manually during every
other refueling operation.
The oil tank capacity is 1.1 liters, 1.2qt.
Fill the tank with high quality JASO FC grade
2 cycle engine oil. Using lower grade oil can
cause exhaust smoke and result in damage to
your engine.
Your first tank of fuel should be a pre-mix fuel
with a 50:1 fuel to oil ratio. This will insure the
engine is lubricated and give the oil pump
time to bleed any air from the oil line that may
have occurred during shipping.
Tires and Wheels
Tire & Wheel inspection
It is important to inspect your tires and wheels
for damage and wear before each riding
session. Inspect each tire for cuts, tears and
punctures. Inspect the wheel rim for dents
and separation of the wheel from the tire bead.
Replace any tire or wheel found to be
damaged.
Operating your ATV with damaged tires or
wheels is dangerous. Damaged tires or
wheels can result in a sudden loss of tire
pressure and control which could result in
injuries.
Check your tire pressure before each riding
session and at each refueling operation. Always
check the pressure when the tires are cool. Use
the tire pressure gauge that came with your ATV
to check the tire pressure.

7psi Maximum (Hot – after riding awhile)
