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.
