assembly (704153) to manifold-handle (744303) hole marked #3 in an upright position.
3. Connect the tool to air supply and cycle tool ten times, holding the lever (704345) down for 2-3 seconds between cycles to remove
any air from the tool.

7. Disconnect air supply. Remove air bleeder assembly (704153) and replace button head cap screw (402482) and stat-o-seal (S572)
on the head cylinder assembly (752120). Torque to 35-40 inch lbs. (3.95 - 4.52 Nm). (Do NOT over-tighten).
8. Connect air supply. Cycle tool 5-6 times and check stroke of .500" (12.7 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) check dimension (B).
c. Subtract dimension (A) from dimension (B). If stroke is not consistent within 1/64" (.396 mm) repeat bleeding procedure 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.
