Tire Pressure
Tire Inspection
Tire Tread Depth
Always replace tires when tread depth is worn to 1/8” (3 mm) or
less.
ELECTRICAL AND IGNITION SYSTEM
Battery Maintenance
Keep battery terminals and connections free of corrosion. If
cleaning is necessary, remove the corrosion with a stiff wire
brush. Wash with a solution of one tablespoon baking soda and
one cup water. Rinse well with tap water and dry off with clean
shop towels. Coat the terminals with dielectric grease or
petroleum jelly.
NOTE: Absorbed Glass Mat (AGM) batteries are
permanently sealed at the time of manufacture.
AGM batteries are designed to minimize gassing and
water loss, but can vent if overcharged.
IMPORTANT: Never attempt to open the battery. If the
seal is broken, the battery will be ruined and will fail
within a few weeks.
NOTE: If battery voltage is below 12.6V, fully charge
the battery before putting into service. Charge for 3-
5 hours at a voltage not to exceed 14.6V or 10 Amps.
Voltage should reach at least 14.4V before end of
charge.
Tire Pressure Inspection (PSI - Cold)
Front Rear
7 psi (48 kPa) 5 psi (34.5 kPa)
WARNING
Operating an ATV with worn tires will increase
the possibility of the vehicle skidding and
possible loss of control.
Worn tires can cause an accident.
Always replace tires when the tread depth
measures 1/8” (.3 cm) or less.
CAUTION
Maintain proper tire pressure.
Refer to the warning tire pressure decal
applied to the vehicle.
Improper tire inflation may affect
ATV maneuverability.
When replacing a tire always use original
equipment size and type.
The use of non-standard size or type tires may
affect ATV handling.
Tread
Depth 1/8” (3 mm)
WARNING
Battery electrolyte is poisonous. It contains sulfuric
acid. Serious burns can result from contact with
skin, eyes or clothing. Antidote:
External: Flush with water.
Internal: Drink large quantities of water or milk.
Follow with milk of magnesia, beaten egg, or
vegetable oil. Call physician immediately.
Eyes: Flush with water for 15 minutes and get
prompt medical attention.
Batteries produce explosive gases. Keep sparks,
flame, cigarettes, etc. away. Ventilate when
charging or using in an enclosed space. Always
shield eyes when working near batteries. KEEP
OUT OF REACH OF CHILDREN.
