Before you begin, make sure the ram is fully
retracted. Install
25PUSH400 (also referred to
as the pusher hat) onto the main pusher plate.
This is required for all standard Holedall fittings.
Make sure the bolt holes align with the 1/2”
bolts and wing nuts supplied.
Select the proper pusher for the I.D. of the hose.
The pusher should be the same size as the stem.
There are separate pushers required for 1 1/4”
through 3” I.D. hose.
Insert the selected pusher into the
25PUSH400
and secure it with the set screws provided.
For Unirange (1” and below) remove the
25PUSH400 and install the 25PUSH100 as well
as the correct pusher for the size of Unirange
coupling. There is a separate pusher for each
unirange assembly size.
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.
Insert Die Holders into the Die Bed Plate as follows:
a)
DH9-004 - Master Die Holder to hold all of
the other die holders.
b)
DH9-004-1 - Die Holder for 4” I.D. hoses only.
c)
DH6-003 - Die Holder for 1 1/4” - 3” I.D. hose
dies (fits into DH9-004).
d)
DH3-001 - Die Holder for 1/4” - 1” I.D. hose
dies (DH6-003 and DH9-004 also required).
Secure the Die Holders with the tie down bars supplied.
