General Safety Information
• Remove port plugs before
attempting to pressurize the cylinder.
• Keep hands and clothing away from
the air cylinder during operation.
• Do not exceed the pressure rating of
any component in the system.
• Protect airlines connected to the
cylinder from damage or puncture.
• Check airlines for weak or worn
conditions on a periodic basis and
before each use; making certain all
connections are secure
Remove all system
pressure prior to
cylinder disassembly!
Assembly
All cylinders are shipped fully
assembled. Mounting kits require
attachment to the cylinder using four
screws, included in the kit. Mounting
attachment instructions are shown
below for each mounting kit and rod
clevis.
MOUNTS
SIDE LUG MOUNT (STOCK NOS.
1A254 THRU 1A259)
Attach one side lug plate to the head
and one to the cap of the cylinder using
screws provided. Tapped holes are
machined in the head and cap for this
purpose. The tapped holes may also be
used for flush mounting the cylinder to
a flat surface.
FRONT / REAR FLANGE MOUNT
(STOCK NOS. 6X470, 6X472, 6X474,
6X478, 6X480 AND 1AO16)
NOTE:
Eight (8) screws are provided
with each kit. (4) long and (4) short.
Front Flange – Secure rectangular
mounting flange to the head (rod end)
of the cylinder using (4) long screws.
The mounting screws pilot into the
internal threads of (4) sleeve nuts
located in the cylinder head.
Rear Flange – Secure rectangular
mounting flange to the cap of the
cylinder using (4) short screws. The
mounting screws thread into (4) tapped
holes located in the cylinder cap.
REAR CLEVIS MOUNT (STOCK NOS.
6X471, 6X473, 6X475, 6X479, 6X481
AND 1A017)
Fasten the rear clevis mount to the cap
using the (4) screws provided.
Mounting screws thread into (4) tapped
holes located in the cylinder cap. Rear
Clevis Mount is supplied with a pivot pin.
ROD CLEVIS (STOCK NOS. 6X476,
6X482, AND 1A018)
Grip the piston rod using wrench flats
while threading the Rod Clevis onto
threads of piston rod. Rod Clevis is
supplied with a pivot pin.
EYE BRACKET (STOCK NOS. 6X477,
6X483 AND 1A019)
Eye Brackets are used as a mounting
accessory with Rear Clevis Mount or
Rod Clevis. (4) thru holes in each corner
of the Eye Bracket provide a means of
mounting the Eye Bracket to a flat
surface. The single eye of the bracket
mates with the double ears of either
the Rear Clevis Mount or Rod Clevis.
Align holes in both components and
insert pivot pin.
NOTE:
Eye Brackets are
not supplied with a pivot pin.
Installation
• To prolong cylinder life the use of a
filter, regulator and lubricator is
recommended.
• Proper alignment of the piston rod in
relationship to the load being moved
is essential for trouble-free operation.
• Eliminate any binding of the piston
rod over the full length of both the
extension and retraction stroke.
• Use Teflon tape or pipe thread
sealant to ensure leak-proof
connections.
• Do not scar or deform the surface of
the chrome-plated piston rod. Use
the wrench flats when attaching
accessories to the piston rod.
