Before you begin, make sure the ram is fully
retracted. Install 25PUSH400 (also referred to as
the pusher hat) onto the main pusher plate. Install
the MISCPUSH into the 25PUSH400 and secure
with set screw.
Insert Die Holders into the Die Bed Plate as
follows:
a) DH9-004 - Die holder. This is necessary to
hold all of the other die holders.
b) DH6-003 - Die holder for 1 1/4” - 3” I.D.
hose dies.

Secure the die holders with the keeper plates supplied.
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.
Make sure the hose end is cut square. If the hose is to
be static grounded, follow hose manufacturers
procedure for proper static grounding.
Slide the ferrule onto the hose. Place a mark on the
hose at the end of the ferrule. Move the ferrule 1/8”
from the mark just made towards the end of the hose.
Place a second mark on the hose at the end of the
ferrule.

Lubricate the O.D. of the stem and the I.D. of the hose
with Dixon lubricant or equivalent.
Insert the end of the fitting into hose. Assemble ferrule
onto stem by sliding turned over portion of ferrule past
notched section of the stem collar. Rotate the ferrule
90° (1/4 turn). With ferrule and stem engaged, continue
installing stem until ferrule reaches the second mark
made on the hose.
Lubricate the outside of the ferrule with Crisco®
(recommended) or a high viscosity oil or heavy duty
grease.

Lubricate the I.D. of die halves with Crisco® (recommended) or a high viscosity oil or heavy duty grease.
Insert the hose with fittings through the bottom of
the ram (between the die holders) to allow enough
room to install the die halves into the die holder.

“Jog” the ram by quickly depressing and releasing the
“on” button on the remote control switch, (or by
depressing the foot pedal) until the ferrule enters the
opening of the die. Go slowly as the ferrule enters the
die, making sure that the end of the ferrule does not
contact the face of the die.
Make sure that the stem and ferrule are forced securely
against the pusher until the swaging process has begun.
To complete the swaging process, depress and hold
the “on” switch of the remote control unit (or depress
the foot pedal). Once the ferrule has entered the die
and starts to be reduced (approximately 1/3 of the
way), it will no longer need the operator to keep
it seated into the pusher. Continue the swage until the
pusher meets the die.

Note: The spacer ring will enter the die.

Lift the hose assembly up and remove the pusher,
spacer ring and die halves from the
die bed. Remove excess lubricant.
Note: If gauge reads 10,000 PSI before swaging is
complete, than the ferrule or die used for that hose
end may be incorrect.
