UNDERSTANDING WARNINGS
As with all snowmobiles, caution must be observed to ensure operator
safety. Particular caution must be taken to make sure that the
snowmobile is in excellent operating condition at all times. It is
strongly recommended that the operator as well as an adult check
major and vital safety components each time before riding.
All Polaris snowmobiles have been designed and tested to provide safe
operation when used as directed. Failure of critical machine
components may result from operation with any modification;
especially those which increase speed or power. There is a significant
possibility of loss of control at higher speeds.
Due to our concern for the safety of our customers and the general
public, Polaris hereby requests that consumers do not install on a
Polaris snowmobile any equipment which is intended to increase the
speed or power of the machine, or make any other modifications to the
machines for these purposes. Any modifications to the original
equipment or the snowmobiles substantially increase the risk of bodily
injury. Be aware that these modifications may create a substantial
safety hazard.
Polaris hereby informs you that the warranty on a snowmobile is
terminated on the entire machine if any such equipment has been added
to the machine or any modifications have been made to the machine
which increase its speed or power.
We also advise you to strictly follow the recommended maintenance
program outlined on pages A--37-A--67. This preventive maintenance
program is designed to ensure that all critical components on the
snowmobile are thoroughly inspected by your dealer at various mileage
intervals.
Your snowmobile is not a toy. It is a well-engineered and
well-constructed recreational vehicle. The following information is
provided to aid you in its safe operation.
