GENERAL INFORMATION
Certain parts of the primary clutch can be replaced (recoil
spring, calibration weights, etc.) to improve the performance of
the vehicle at high altitude. The "High Altitude Technical Data"
appendix at the rear of this manual contains all the information
for calibration at high altitude.
Such modifications should only be carried out by
experienced mechanics because of the effect the
modifications could have on vehicle performance.
Any repair of the primary clutch must be carried out by an
authorized Snow Hawk dealer or by a competent person.
When installing parts, follow to the letter all the points
given in the procedure and respect the assembly
tolerances.
