GENERAL

The Astro Tool 612179 7-step crimp tool is a cycle
controlled, precision crimp tool capable of crimping
wire barrel sizes 12 to 20.
Observe the precision ratchet action by opening and
closing the tool several times. Note that the tool cannot
be opened without fully completing the crimp cycle.
When held, the tool fits your hand for less fatiguing one
hand operation.

BASIC TOOL OPERATION

NOTE: For proper crimping, the Basic Tool must be
used with an appropriate Positioner or Turret Assembly.
1. Select the proper Positioner or Three Position
Turret Assembly for the contact to be crimped.
2. Attach the head to the turret ring on the tool using
the captive socket head cap screws. A 9/64 hex wrench
is required. Verify that the guide pin is properly located
prior to tightening the cap screws. The turret will need
to be in the "un-locked" position before attaching to the
tool.
