b. Outrigger Cylinder Disassembly
Note: An additional o-ring may be included at the base
of the cylinder rod. This additional o-ring may be
discarded, as it served only in a temporarily protective
role.
1. Clean the outrigger cylinder (4) with a suitable
cleaner before inspection. Remove all dirt, debris
and grease from the cylinder.
IMPORTANT: Avoid using excess force when clamping
the cylinder in a vise. Apply only enough force to hold the
cylinder securely. Excessive force can damage the
cylinder tube (5).
2. Place the outrigger cylinder in a soft-jawed vise or
other acceptable holding equipment if possible.
3. Slowly remove the counterbalance valve (6) and the
pilot-operated check valve (7) from the outrigger
cylinder.

WARNING:
Significant pressure may be
trapped inside the cylinder. Exercise caution
when removing a counterbalance valve or a pilot-
operated check valve from a cylinder. Escaping
hydraulic fluid under pressure can penetrate the
skin, causing death or serious injury.
