A.
INSTALLATION:
(Follow All Safety Lockout/Tagout Procedures)
The cylinder is shipped from the factory with the MIRACALUBE self-lubrication
system (filled at the factory at the time of assembly). It is not necessary to add
grease or other lubrication to the unit prior to installation.
The cylinder is shipped with protective caps in the ports. Do not remove these
caps until the piping is ready for installation. If the cylinder has been in storage
for an extended time, it is advisable to exercise the cylinder; i.e., flex the internal
seals by stroking the piston before installation. Insure the air line used is equipped
with suitable filters, pressure control and a water trap.
Alignment of the piston rod with the work is necessary for the cylinder to operate
satisfactorily and insure long seal and rod bearing life. Be sure all mounting
surfaces are clean, smooth, flat and in alignment. Before finish piping of the
cylinder, stroke the cylinder using the air line to check the mounting arrangement
for misalignment or binding of attached mechanisms. The piston rod should
extend and retract without any unsteady or jerky motion.
If the cylinder is equipped with cushions, adjust the cushion screws to produce the
desired effect for the load, speed and air line pressure to which the cylinders will
be subjected under normal operating conditions.
B.
TROUBLE SHOOTING:
1.
JERKY ACTION:
Check for misalignment. Look for a bent or scored piston rod. The rod
bushing may be damaged. Check the cylinder tube for dents or bumps.
Confirm that the air cylinder supply pressure and volume are adequate to
operate the cylinder under normal conditions.
2.
AIR LEAKAGE:
a.
Loss of Power or No Power:
1.
Check the air pressure at the machine. Then check the operating
pressure at the control valve for the cylinder and check the line
pressure at the cylinder port(s).
2.
Apply air pressure to one port of the cylinder and check for
escaping air from the opposite port or the exhaust port of the control
valve.
