WARNING!
1. It is advisable to have an Öhlins dealer
or other qualified person install the shock
absorber.
2. Follow the instructions in the vehicle
service manual when changing the shock
absorber.
3. When working on a raised vehicle, make
sure that it is securely supported to prevent
it from falling.
1
Compress the front part of the rear
suspension so that the limiter strap is no
longer tight.
A tip: Put a large piece of wood
under the front part of the rear suspension to
raise it and thereby loosen the tension of the
limiter strap.
2
Remove the screw of the limiter strap. Note
the position of the screw! The screw must
be installed in the same position as before
installation.
3
Raise the rear end of the snowmobile so that
the track is off the ground. Make sure the
vehicle is securely supported so that it will
not fall over.
