WITH SET-UP DATA
During storage and transportation, espe-
cially at high ambient temperature, some
of the oil and grease used for assembling
may leak and stain the packaging. This is
in no way detrimental to the product, wipe
off the excessive oil/grease with a cloth.
INSTALL THE SHOCK ABSORBER
WARNING!
It is advisable to have an Öhlins dealer install the
shock absorber.
WARNING!
Make sure that all screws are tightened to the
correct torque and that nothing fouls or restricts
movement of the shock absorber when the sus-
pension is fully compressed or extended.
WARNING!
Make sure the vehicle is securely supported so
that it will not tip.
1
Raise the front end of the vehicle so that the
original shock absorbers are in a neutral posi-
tion.
CAUTION!
Do not apply lifting force to the A-arms.
2
Remove the original shock absorbers.
3
Install the Öhlins shock absorbers. The cylin-
der head should be at the top and the piggy-
back reservoir facing the rear of the vehicle.
Fasten the upper attachment fi rst.
4
Fasten the lower attachment. Raise or lower
the wheels slightly to make the attachment fi t.
5
Tighten the attachment screws to the correct
torque. Consult your ATV Owners manual.
6
Read more about your shock absorber in the
Öhlins Owner’s Manual. See also Set-up data
for this specifi c shock absorber kit on the
