Always test the remote
switch before beginning a riding session. The
remote switch is operated by a battery which
should be replace one a year. You can obtain

Fuel Tank

The fuel tank fill cap is located on top of the
unit just ahead of the seat. The cap contains
a vent to prevent a vacuum from forming in
the tank as fuel is used. The vent tube must
be attached to the cap and inserted in the
vent tube holder hole while operating the unit.
The fuel cap vent and vent tube must be
clean and clear of obstructions for the unit to
operate normally. You can check the vent and
vent tube by blowing air through the tube. If
you can not blow through the vent tube and
cap you must clean the vent and tube or
replace them.
Every time you refuel your unit, check the
rubber seal inside the cap for cuts, tears and
dirt. Clean or replace the seal if it becomes
worn or torn. The seal must be in good
condition to insure a proper seal of the cap to
the tank to prevent fuel spills. DO NOT allow
dirt or other debris to enter the tank when
refueling.
Replace the cap if damaged or if it will not seal
to the tank.
Tighten the cap snugly, being careful not to over
tighten. Over tightening the cap can cause
damage to the cap or seal.
The fuel tank capacity is 4.5 liters, 1.2 gal,
including a reserve of 0.8 liters, 0.2 gal.
Use unleaded automobile gasoline with an
octane level of 91 or higher.
NEVER REFUEL YOUR ATV when the
engine is HOT.
Wait 30 minutes after turning
off the unit before refueling. Spilling fuel on a
HOT engine could cause a fire. Wipe up any fuel
spills before re-starting.

Fuel Valve

The unit is equipped with a three way fuel valve
located on the left side of the unit just below the
seat.
The valve has three settings; "OFF", "ON" and
"RES". With the valve in the "OFF" position fuel
is held in the tank and is prevented from flowing
to the carburetor. The valve should be placed in
the "OFF" position whenever the unit is not being
operated. Place the valve in the "ON" position for
normal operation of the unit. This allows fuel to
flow to the carburetor for normal operating. The
"RES" position allows fuel to flow from the small
