Cleaning and Storage
Storage Tips
Battery Maintenance (Conventional)
Remove the battery and add distilled water to the proper level. Do not
use tap water, which may contain minerals that reduce battery life.
Apply dielectric grease to the terminal bolts and terminals. Charge the
battery at 1.4 amps or less until the specific gravity of each cell is
1.265 or greater. Store the battery in a cool, dry place.
Charge can be maintained easily by using Polaris Battery Tendert
charger (PN 2871076) or by charging about once a month to make up
for normal self-discharge. Battery Tendert can be left connected
during the storage period, and will automatically charge the battery if
the voltage drops below a pre-determined point. Check the fluid level
monthly.
Battery Maintenance (Sealed)
Remove the battery and recharge it as outlined on page 105. Store the
battery in a cool, dry place.
Engine Anti-Freeze
Test engine coolant strength and change if necessary. Coolant should
be replaced every two years.
Storage Area/Covers
Set the tire pressure and safely support the ATV with the tires 1-2" off
the ground. Be sure the storage area is well ventilated, and cover the
machine with a genuine Polaris ATV cover. NOTE: Do not use plastic
or coated materials. They do not allow enough ventilation to prevent
condensation, and may promote corrosion and oxidation.
