GENERAL AIR CIRCUITRY TROUBLE SHOOTING
IF A CYLINDER IS NOT FUNCTIONING CORRECTLY HERE ARE A COUPLE
OF ITEMS TO CHECK:
Most cylinders have an extend and retract port. To adjust the extend motion of a
cylinder you must adjust the flow control on the retract port; this regulates the air flow
exhausting from the cylinder and the opposite is true for the retract motion.
1. Check the air pressure to the machine.
2. Check the flow controls to see that they are adjusted correctly and to the proper
specifications.
3. Check for and obstructions to the cylinders such as screws or a misplaced tool etc… *
FOLLOW ALL SAFETY GUIDELINES AND SIGNS DURING THIS PROCESS.
4. Check the solenoid air valves:
The solenoid valves can be manually operated by pushing the slotted button on the end
of the valve. If you wish to keep the valve open, the push button assembly can be
removed using an open ended wrench and inserting a 3/8” N.C. cap screw. DO NOT
over tight when reassembling the valve.
5. If the valve seems to be leaking, the seals may be dry or contaminated with water or it
maybe that the cylinder “O” rings are damaged and air is passing from one side to the
