Problem:
• A cylinder that has been replaced exhibits slow or hesitation in movement (starts to move then stops,
then starts to move again).
The cylinder barrel clamps may have been over tightened causing the barrel to compress, restricting
piston movement. Loosen and retighten the barrel clamps. (See Bolt Torque Requirements section). If the
system has been operated or continues be operated with over torqued clamps, damage to the piston rings
will occur resulting in an internal bypass in the cylinder.
Problem:
• After a cylinder has been replaced, it moves properly and engages the check valve, but the next
cylinder stops before reaching the check valve.
The cylinder was not installed in the correct position and is physically stopping the next cylinder from
reaching it’s check valve.
