necting the + (red) lead to the + (positive) battery ter-
minal and the - (black) lead to the - (negative) battery
terminal.

clamps; then secure with the two 6 mm flange cap
screws and tighten securely.
4. Place the handlebar cover into position on the han-
dlebar cover mount and secure with the two 5 mm
cap screws with washers.
5. Make sure the cables (brake and throttle) are routed
down and away so there is no sticking or binding.
Make sure there is maximum right/left steering capa-
bility and the brake and throttle cables are not
affected.

Tire Inflation Pressure

Operating an ATV with improper or uneven tire infla-
tion pressure is hazardous. Always maintain proper
tire inflation pressure.
Use a low-pressure gauge to measure the air pressure in the
tires. Check the air pressure in all tires before use of the
ATV. Recommended tire pressure is 27.6 kPa (4.0 psi).
 NOTE: The ATV is equipped with low-pressure
tubeless tires of the size and type listed. Do not
under any circumstances substitute tires of a differ-
ent type or size.
