SHOCK OIL FILLING
Fully extend the piston rod so the piston is at the
bottom of the shock body.
Hold the shock upright and slightly overll the shock
body with shock oil.
Let the oil settle and allow air bubbies to rise to the
top. Slowly move the piston up and down until no
more air bubbies appear. Add shock oil as necessory.
Pull the piston rod most of the way out of the shock
body. Let the shock rest for 5 minutes to allow the air
bubbles to escape.

SHOCK OIL & SPRING ASSEMBLE
* When installing the shock cap assembly
on the shock body, some oil will leak
out.... this is normal.
* Fully tighten the cap and clean off any
excess oil.
* After the shock is assembled, the shock
rod will push itself out of the shock body
fairly quickly.
