PMM-1 Portable Swage Instructions
I. Preparation of PMM-1 Portable Swaging
Machine
Clean and lubricate Acme lead screw assembly.
Use lightweight lithium or molybdenum-based
grease.
Clean and relubricate as required, particularly if
the tool has been exposed to dust or dirt
during storage.
II. Versatile Features of PMM-1 Include
Three methods of mounting: bench, vise, or
horizontal unsecured for ground or flat work
surface.
Swage die retaining clips for horizontal position.
Thumbscrew for quick change of coupling
pushers.
Optional crank handle box end wrench part
number 821072.
III. Swaging in Vertical Bench Mounting Position
Install appropriate pusher, part number selected
from coupling style charts in 4660 Parflex
catalog fitting section.
Clean and lubricate bore of swage dies with
high film strength Oil. Repeat after two or three
swages. Use Parker 702 oil when swaging stain-
less steel couplings and lubricate each coupling.
Install two-piece split die in bowl. Select proper
die for specific coupling style and hose size from
assembly tool selection chart in the 4660 cata-
log.
After having properly inserted hose into coupling
and marking insertion depth, remove or elevate
one die segment to allow installation of hose and
coupling.
Insert coupling all the way into pusher and exert
an upward force; replace die segment in bowl of
swager. Verify proper alignment with mating die
half.
If lubrication has not previously been
accomplished, now is another opportunity to
lubricate dies.
Note: To avoid premature wear of dies, it is es-
sential to distribute oil around the complete bore
of dies.
Using an appropriate wrench, begin clockwise
rotation of hex drive nut. As skirt of coupling
approaches the die opening, properly align entry
of coupling by deflecting the hose as required
continuing to exert an upward force on hose and
coupling to keep it fully inserted in pusher.
Note: The crank style box end wrench part num-
ber 821072 is recommended as it
eliminates slipping and provides easier nonstop
rotation of drive nut.
Continue swaging stroke until bottom face of
pusher fully contacts top face of dies.
Retract pusher sufficiently to allow removal of
swaged coupling.
Measure swaged diameter of coupling and
inspect threads of male style couplings for any
indication of damage. On female swivel style
couplings, inspect for free rotation and condition
of nut.
IV. Swaging in Horizontal or Unsecured Position
Position torque reaction arm at 90° to the center
line of the machine.
Following insertion of hose/coupling assembly
into machines, it is necessary in this position to
secure the die halves with the spring retaining
clips provided.
In the horizontal position, it is easier and
recommended to insert both die halves at the
same time after the hose and coupling have
been inserted.
Each of the previously specified procedures
also applies to use of the PMM-1 swager in this
position.
V. Vise Mounting
Secure PMM-1 swager in vise using only the lug
or ear provided.
DO NOT ATTEMPT to vise mount by gripping the
round and tapered base of the machine. To do so
can result in serious injury.
Using the vise lug, the machine may be mounted
at an inclined angle or may be mounted
horizontally using the full area of the mounting
lug; this will be determined by the work area
arrangements.
Note: When using the PMM-1 swager in the reaction
arm position or the vise mounted position,
it will not be possible to maintain constant
rotation of the driving nut. It is recommended,
however, that a continuous, smooth stroke be
maintained whenever possible.
