Before installation

Öhlins Racing AB can not be held
responsible for any damage what-
soever to shock absorber or vehicle,
or injury to persons, if the instruc-
tions for fitting and maintenance are
not followed exactly.
Similarly, the warranty will become
null and void if the instructions are
not adhered to.

WARNING!

1. Installing a front fork, that is not
approved by the vehicle manufac-
turer, may affect the stability of your
vehicle. Öhlins Racing AB cannot
be held responsible for any per-
sonal injury or damage whatsoever
that may occur after fitting the front
fork. Contact an Öhlins dealer or
other qualified person for advice.

2. Please study and make certain
that you fully understand all the
mounting instructions and the own-
ers manuals before handling this
front fork kit. If you have any ques-
tions regarding proper installation
procedures, contact an Öhlins
dealer or other qualified person.

3. The vehicle service manual must
be referred to when installing the
Öhlins front fork.

Öhlins products are subject to con-
tinual improvement and develop-
ment. Consequently, although these
instructions include the most up-to-
date information available at the time
of printing, there may be minor dif-
ferences between your suspension
and this manual. Please consult your
Öhlins dealer if you have any
questions with regard to the contents
of the manual.

NOTE!

During storage and transportation,
especially at high ambient tempera-
ture, the oil and grease used for
assembling may run out inside the
packing and damage the expanded
polystyrene packing material. This is
not unusual and is in no way detri-
mental to the shock absorber.
