What if I have to remove the cylinder for replacement or maintenance?

Please note that it is not recommended to tamper with or attempt to remove the cylinder without sufficient techical knowledge.

Specific Trouble Shooting Scenarios

ISSUE: Press cycles down fine, but sometimes does not return right away, or the return stroke is very slow.

RESOLUTION: First check for leaks in the power valve.  Any air hissing from exhaust ports on the valve means you need a cylinder seal Kit.  Secondly, check the A-1030 , mechanically, the impulse pin should be retracted during the up stroke.  Replace A-1030 as first suspect part.   Replace E-power valve as secondary suspect part.
