stationary die, a cylinder which contains the head's
Crimping
hydraulic chamber, a piston (ram) which holds and
Head
controls the moving die, and a quick--disconnect
("C"- - Head)
coupling (cylinder half) which mates with the coupling
on the hose to release or supply pressure. A dust cap
covers the quick--disconnect coupling.

3. INSTALLATION

Quick- - Disconnect
Coupling

3.1. Head Installation

(Figure 1)
Prior to installing the head, ensure 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.
Oil flow must be unobstructed between the power
unit and the crimping head. Ensure that all
!
couplings are fully mated and tightened.
If a crimping head must be removed after the
power unit was in operation, be sure to release
the pressure in the hydraulic system. When using
Hydraulic Power Unit 1804700- - [ ],
DISCONNECT THE POWER UNIT FROM THE
POWER SUPPLY. When using Hydraulic Foot
Pump 1583659- - 1 or Hydraulic Hand Tool
1583661- - 1, depress the pressure release pedal
to release pressure.
