1a
Install the 6" main pusher (MPUSH600) by sliding it
onto the rod cap of the ram cylinder. Make sure that the
pusher is all the way on the rod cap.
For 1¼" - 5" couplings proceed to Step 1b.
For 6" couplings, proceed to Step 2.
1b
For 1¼" - 5" couplings insert the appropriate size adapter
pusher into the 6" main pusher (MPUSH600). Shown
here is the 2" adapter pusher (50TPUSH200) being
inserted.
2
Install the required die holders ensuring that the seams
between the die holder halves do not line up. The die
holders are designed to fit one inside the other.
A guideline for selecting die holders is:
50TDH6003 1¼" - 3" I.D. hose
50TDH9004 4" - 6" I.D. hose
Caution! Never use a swaging die as a die holder!
Secure the die holders with tie down bars to prevent the
die holders from slipping out of the die bed unexpectedly.
3
Accurately measure the hose O.D. with a diameter tape.
Each end of the hose should be measured to guarantee
the correct ferrule and die selection. Select the correct
ferrule and die based upon the hose free O.D. just
measured from the die chart.

Assuring that the hose end is cut square, chamfer the
I.D. of the hose ⅛" at a 45° angle. This will aid in stem
insertion. If the hose is to be static grounded, follow hose
manufacturers procedure for proper static grounding.
5
Lubricate the I.D. of the hose and the O.D. of the stem
with Dixon Coupling Lubricant or equivalent. Insert the
stem all the way into the hose until the ring on the stem
comes in contact with the end of the hose.
6
Slide the ferrule over the stem and over the O.D. of the
hose until the turned over portion of the ferrule rests on
the ring of the stem.
7a
Lubricate the outside of the ferrule with Crisco®
(recommended) or high viscosity oil or heavy duty grease.

7b
Lubricate the I.D. of both die halves with Crisco®
(recommended) or high viscosity oil or heavy duty grease.
8
Bring the hose with the stem and ferrule through the die
bed. Insert the stem into the pusher so that the ferrule
contacts the pusher. Make sure that there is sufficient
room between the die holders and the end of the ferrule
to comfortably insert the die halves into the die holders.
9
Lifting up the hose, insert one die half under the hose.
Lower the hose so that it rests on the die. Insert the other
die half. Make sure that the seams of the die do not line
up with the seams on the die holders.
10
Continue to jog the cylinder until pressure begins to
register on the gauge. Leave the directional control lever
in the "FORWARD" position. Loosen the bolt on the tie
down bar that is holding the die in place. Move the tie
down bar so that the entire flange on the pusher will clear.
Move any other tie down bars that may interfere with the
pusher. When the pusher contacts the die release the
pressure. Important! Inspect the position of the stem and
ferrule with the pusher. Make sure the collar (ring) on the
stem is in contact with the ferrule before proceeding.

Move the directional control lever to the "REVERSE"
position and depress the button on the remote. Retract
the cylinder far enough (approximately 1") to allow a tie
down bar be placed so that the die does not come out
of the die holder. Secure the tie down bar by tightening
the bolt. Continue retracting the cylinder until there is
sufficient room for the stem and ferrule to clear the die
bed.
12a
Position a rubber sheet or pad under the die bed. While
holding the die in place with one hand, loosen the bolt
on the tie down bar and move the tie down bar so that it
clears the die. Slowly slide the hose towards the pusher.
When the die clears the die holder, one or both halves
may fall to the floor. If one half remains on the ferrule, tap
it with a mallet until it releases. If both halves remain on
the ferrule, it may require the halves be pried apart at the
seam.
12b
Wipe excess lubricant from hose and ferrule. Bring hose
with stem and ferrule back through die bed.
