ESU00245 

Strap

For RS90M

The strap 

1

 should be used only by experienced opera-

tors to assist them when traverse (side-hill) riding.

WARNING

Improper use of the strap on the handlebar can
result in severe injury or death. 

Use the strap only as an operator grip point when
needed to shift weight uphill to maintain balance
during traverse (side-hill) riding. Only experi-
enced operators should traverse slopes steep
enough to require strap use. 

Keep the right hand on the right handlebar grip
for steering, and grip the strap with the left hand
to shift weight uphill for balance during traverse
riding. 

Ride cautiously while using the strap. Do not
accelerate or decelerate abruptly while holding
onto the strap. 

Do not use the strap to lift the snowmobile. 

Do not use the strap as a mounting point for
cargo or accessories.
