FILLING AND BLEEDING PROCEDURE
Images may not reflect actual tool
1.
Disconnect air supply from the powerunit.
2.
Fill oil reservoir approximately 3/4 full. Use hydraulic oil (AW
-
32 or equivalent).
3.
Carefully remove button head cap screw (402482) and stat
-
o
-
seal (S572) from hole (marked #1) on the right side of head cylinder (745366).
4.
Provide a suitable container to bleed oil into.
5.
Reduce air pressure to 40 psi. (2.76 bar) during bleeding procedure. Connect air supply to powerunit.
6. Point the bleed port towards a container, push lever (704345) down and hold. (Block bleed port using a small piece of rubber material
before releasing lever (704345) to prevent ingestion of air into powerunit).
7
Repeat until clear oil streams from port. Check reservoir after each cycle and refill when required. Do NOT drain reservoir below minimum.
8.
On last cycle of oil, hold lever (704345) down. Install button head cap screw (402482) and stat
-
o
-
seal (S572) prior to releasing the lever
(704345) and torque to 35
-
40 inch lbs. (3.95
-
4.52 Nm). (Do NOT over
-
tighten)
9. Check stroke of
.620” (15.8
mm) using instructions a thru c and diagrams below. We recommend using dial calipers.
a. With the lever (704345) released, check dimension (A).
b. Holding lever (704345) in, check dimension (B).
c. Subtract dimension (A) from dimension (B). If stroke is not consistent within
1/64” (.0156)
repeat steps 1
-
9 until stroke met.
For your consideration, Gage Bilt offers a depth gage (Pt.# A
-
1935) to help simplify and more accurately check your tool stroke.
Please contact Gage Bilt for more information.
WARNING:
Do not cycle tool without air bleeder assembly (704153), or the screw and stat
