1. INTRODUCTION
This instruction sheet provides operation and
maintenance instructions for the 12 Ton Hydraulic
Crimping Head 1901820–1. See Figure 1.
The crimping head is designed to use dies that crimp
the terminals in Figure 2. Figure 2 also lists the wire
sizes onto which the terminals and splices are
crimped, as well as the instruction sheet for the
crimping dies.

2. DESCRIPTION
(Figure 1)
Main components of Hydraulic Crimping Head
1901820–1 include a “C”–head, which houses the
stationary die, the upper and lower die release
buttons which release the dies, a cylinder which
contains the head’s 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.
3. INSTALLATION
3.1. Head Installation
Prior to installing the head, ensure that the pump
and hose being used are working properly, and
are adjusted to and rated at 10,000 psi. An
incorrectly adjusted or rated pump/hose could
result in severe tooling damage, as well as
personal injury.
1. Release the hydraulic pressure to the hose.
Disconnect electric power unit from power supply.
2. Remove protective dust caps.
3. Thoroughly clean the coupling on the
pump/hose and the coupling on the crimping head.
4. Mate both quick–disconnect couplings and
tighten the collar of the coupler assembly on the
hose.
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.
3.2. Die Installation
To avoid personal injury, do NOT accidentally
depress the footswitch or handle control when
installing or removing dies.
