Battery

Battery electrolyte is poisonous. It contains acid! Serious burns can result from 

contact with the skin, eyes, or clothing. If contact occurs, seek immediate medi-

cal attention.
KEEP OUT OF REACH OF CHILDREN.
EXTERNAL: Flush with water.
INTERNAL: Drink large quantities of water or milk. Call physician immediately.
EYES: Flush with water for 15 minutes and get prompt medical attention.
Batteries produce explosive gases. Keep sparks, open flames, cigarettes, etc. 

away. Ventilate when charging or using in closed space. Always shield eyes 

when working near batteries.

Battery Fluid

A poorly maintained battery will 

deteriorate rapidly. Check the battery 

fluid level often. The fluid level 

should be kept between the upper and 

lower level marks.

NOTICE: Tap water contains minerals 

that will damage a battery and 

shorten its life. Use only distilled 

water to refill your battery. 

Never allow cleaning solution or 

tap water to enter the battery.

Battery Connections

Keep battery terminals and connections free of corrosion. When clean-

ing is necessary, remove the corrosion with a stiff wire brush. Wash ter-

minals and connections with a solution of one tablespoon baking soda 

and one cup water. Rinse well with tap water and dry with clean shop 

towels. Coat the terminals with dielectric grease or petroleum jelly.

Battery Removal

WARNING! Improperly connecting or disconnecting battery cables can result in 

an explosion and cause serious injury or death. When removing the battery, 

always disconnect the negative (black) cable first. When reinstalling the battery, 

always connect the negative (black) cable last.

1. Disconnect the battery hold-down straps.
2. Remove the battery vent tube from battery.
3. Disconnect the black (negative) battery cable first.
4. Disconnect the red (positive) battery cable last.
5. Carefully lift the battery out of the snowmobile. Do not tip it side-

ways or spill electrolyte.

NOTICE: If electrolyte spills, immediately wash it off with a solution of one table-

spoon baking soda and one cup water to prevent damage to the vehi-

cle.

Battery Installation

WARNING! Battery electrolyte contains acid. Avoid skin contact with electrolyte 

as severe burns may result.

Using a new battery that has not been fully charged can damage the bat-

tery and result in a shorter life. It can also hinder vehicle performance. 
1. Ensure that the battery is fully charged.
2. Place the battery in the battery holder. Attach the hold down strap.
3. Install the battery vent tube. The vent tube must be free of obstruc-

tions and securely installed. Route the vent tube properly to prevent 

kinks and to allow for proper drainage.

WARNING! Batteries contain gases that can explode. If the battery vent tube is 

pinched or kinked, battery gases could accumulate. Always ensure that the vent 

tube is free of obstructions and is securely installed as recommended. 

Whenever removing or installing the battery, disconnect the negative (black) 

cable first and reinstall the negative cable last to avoid the possibility of 

explosion.

4. Coat the terminals with dielectric grease or petroleum jelly.
5. Connect and tighten the red (positive) cable first.
6. Connect and tighten the black (negative) cable last.
7. Verify that cables and vent tube are properly routed.
