Service Information
WARNING: INSTALLATION
and MOUNTING
The user of these devices must conform to all applicable
electrical, mechanical, piping and other codes in the
installation, operation or repair of these devices.
INSTALLATION! Do not attempt to install, operate or
repair these devices without proper training in the
technique of working on pneumatic or hydraulic
systems and devices, unless under trained
supervision.
Compressed air and hydraulic systems contain high
levels of stored energy. Do not attempt to connect,
disconnect or repair these products when a system is
under pressure. Always exhaust or drain the
pressure from a system before performing any
service work. Failure to do so can result in serious
personal injury.
MOUNTING! Devices should be mounted and
positioned in such a manger that they cannot be
accidentally operated.
INSTALLATION
Before installing this cylinder, all air lines in the system
should be blown clean to remove any moisture or loose
material. Also, the area in which the cylinder is to be
mounted should be free of any foreign objects, which may
damage the cylinder barrel. To further ensure a long,
trouble-free service, an efficient air filter should be installed
in the system’s supply line.
Start the installation by removing one cotter pin and clevis
pin from the clevis on the cap end of the cylinder. Set the
cylinder into the mounting position with the cap clevis
mating with the mounting eye. Reinstall the clevis pin
through the clevis lugs, and the cotter pin into the clevis pin.
Spread the ends of each cotter pin so that they will not fall
out. You can now connect the piston rod end to the
mounting bracket, noting proper alignment to eliminate any
binding.
Remove the thread protectors from each pipe port in the
head and cap; connect air lines from the directional control
valve. Use pipe dope on the air line fittings, not any kind of
tape. Be sure no foreign matter enters the ports or air lines
during the time they are open.
If the cylinder is to be painted, be sure that the piston rod is
covered, the ports are closed, and the clevis pin is covered
where it rides in the clevis.
The supply air and atmospheric (ambient) condition must
be maintained within a temperature range of –40°F to
+225°F.
OPERATION
When the cylinder installation is completed correctly, air
pressure delivered from the directional valve to the port on
the cap end of the cylinder will extend the piston rod. A shift
of the valve to exhaust that air and to apply air pressure to
the port on the head end will retract the piston rod.
