DESCRIPTION
Main components of this crimping head
include a “C”
-Head, which houses the stationary die, a cylinder which
contains the hydraulic chamber, a piston (ram) which holds and controls the moving die, and a quick-
disconnect coupling (cylinder half) which mates with the coupling on the hose to release or supply pressure. A
dust cap covers the quick-disconnect coupling.

CRIMPING HEAD INSTALLATION
DANGER
Verify that the hydraulic pressure to hose or handle control is released and that power supply is disconnected from electric
power unit, if applicable.
CAUTION
Prior to installing the head, verify that the pump and hose being used are working properly, and are adjusted to and rated at
68948 kPa [10,000 psi]. An incorrectly adjusted or rated pump/hose could result in severe tooling damage, as well as
personal injury.
1. Remove protective dust caps from both quick connect/disconnect couplers.
2. Thoroughly clean the coupling on the pump/hose and the coupling on the crimping head.
3. Mate both quick-disconnect couplers and tighten the collar of the coupler assembly on the crimping
head (see Figure 1).
CAUTION
Oil flow must be unobstructed between power unit and crimping head. Verify that all couplers are fully mated and tightened.
NOTE
If crimping head must be removed after being in production, pressure must be released in the hydraulic system before head is
removed. If using Electric Hydraulic Power Unit 1804700-1 or 2, disconnect power unit from power supply. When using
Hydraulic Foot Pump PN 1583659-1 or Hydraulic Hand Pump PN 1583661-1, depress the pressure release pedal to release
pressure.

DIE INSTALLATION AND REMOVAL
(FIGURE 2)
DANGER
To avoid personal injury, avoid accidently depressing foot switch or handle control of power unit when changing dies.
CAUTION
Operating
the crimping head WITHOUT the dies installed will damage the “C”
-Head or ram.
Installation
1. Back out the set screws in the crimping head and ram (the ram must be raised slightly to gain access
to the set screw).
2. Insert the dies into the crimping head and the ram, ensuring the
“
flats
”
of the die shanks are facing the
set screws. Tighten the set screws.
3. Activate the power unit and slowly close the dies to verify proper alignment.
4. C
omplete the cycle and allow the ram to return to the “DOWN” position.
Removal
DANGER
To avoid personal injury, avoid accidently depressing foot switch or handle control of power unit when changing dies.
CAUTION
Operating
the crimping head WITHOUT the dies installed will damage the “C”
-Head or ram.
1. Back out the set screw in the crimping head and remove the stationary die.
2. Raise the ram enough to expose the set screw and back it out until the moving die can be removed.
