Pressurizing 

Rebuildable Shocks

To pressurize the gas shock absorber, a regulator

system and a nitrogen tank will be needed.

AG271

„ NOTE: Before inserting the needle into the blad-
der, lubricate the needle with light oil to make
installation easier.

1. Insert the Inflation Needle (p/n 0744-020) into

the shock bladder; then open the valve on the

filler handle.

FS079

2. Turn the nitrogen tank valve open and slowly

rotate the regulator T-handle inward until the

gauge reads 200 lb of pressure; then close filler

valve and remove inflation needle.

3. Install the screw into the bladder housing and

tighten securely.

! WARNING

Never have a nitrogen bottle in the area without hav-
ing it chained or secured. If the bottle should tip over
and the regulator break off, the gas inside it is under
1800 lb of pressure and personal injury may result.

! WARNING

Always rotate the regulator T-handle to its loose
position each time when finished using the system.
Each time before the nitrogen tank valve is opened,
check to make sure the regulator T-handle is turned
out. When opening the nitrogen tank valve, never
stand in front of the regulator in case there should
be a problem.
