Bos Deville 2014 User manual - Manual (Page 7)

CAUTION
To get the correct oil level in the cartridge side, you must bleed the air while you are pouring the oil. Once
there is no air remaining in the cartridge you can adjust the level.
IMPORTANT
This is strongly recommended to use BOS Bi'oil oil, otherwise it could significantly alter the behaviour of the
fork and reduce the life of the wear parts.
How to measure the oil level, in the cartridge side :
– Push down the stanchion
– Pull out the rebound rod
– Measure the distance between the top of the stanchion and
the oil (A)
Oil level Deville (all models)
