It is essential to clean your shock after each day of riding without waiting! Nothing is worse for the life of
your seals than dirt and dust.
The cleaning process is also extremely simple: wipe off the body and the seal with a clean, soft rag. You can
occasionally lubricate the exterior of the seal with fork oil.
Do not under any circumstances use degreaser. On the same note, do not power wash the shock's
seals! It will only push the mud inside the shock and get it stuck between the shaft and the seals.

The oil service and full service should be performed by a BOS-approved service center.
Only BOS service centers are able to identify and appraise a damaged or worn part,
especially in case of shock or wear on structural elements such as the chamber, the shaft,
the body.
What is the basic set up?
Your shock has been set up for your bike, with a specific internal valving spring weight. You can find all the
information about standard settings for your bike in the chartlist on the BOS website bos-suspension.com.
Where can I purchase original stickers?
You can purchase these items through your approved BOS center, or on the BOS store on bos-
suspension.com.
I noticed some play between my shock and the frame, what can I do?
Check that your mounting hardware is torqued to your manufacturer’s specifications. If it is, the rear shock
mounting hardware must be replaced. Contact an approved BOS service center, or connect on
bosmtb.com.
My shock makes a whistling or clicking sound when I compress it.
These sounds are normal to the functioning of the hydraulics when the rebound or low-speed compression
circuit is closed or almost closed. Check your settings and bring them closer to the base settings in your
product’s user manual to reduce this noise.
