Operation Procedure
1.
Select the proper dies for the connector to be
crimped.
2.
Install dies in jaws making certain that they are
properly secured by the spring-loaded, positive lock,
die buttons.
3.
Insert conductor into the connector and align the tool
and die on the connector. Start in the center for
splices and “H” frames, and on the end, nearest the
pad, for terminals.
To help minimize hand and arm fatigue and
perceived handle force during use, hold the
crimping tool with your hands at the end of the
handles.
Inspection and Adjustment
Check tools periodically for correct adjustment. As with
any tool, a slight amount of wear may occur over time.
This wear may be corrected by readjusting the tool as
follows:
1.
Remove any die inserts from the tool and make sure
the jaw tips are free of dirt, etc.
2.
Open tool and close handles until jaw tips just touch.
DO NOT CLOSE HANDLES COMPLETELY!
3.
Check that the index marks (red grooves) on the
toggle link and frame line up.

4.
If the marks line up, the tool is in proper adjustment.
5.
If the marks do not line up, loosen the locking set
screw using a 1/4" (6.4 mm) hex key, and then turn
the adjustment screw clockwise or counterclockwise
until the marks line up.
6.
Tighten the locking set screw securely; the tool is
now properly adjusted and ready for use.

4.
Operate the tool by closing, and allowing, the handle
butt/stop blocks to touch. Normally a “pop” will be
heard as the tool goes over center after the crimp is
made.
5.
Continue crimping the connector until the correct
number of crimps have been completed. Work from
the center to the outer edges for splices and “H”
frame connectors, alternating sides if possible, for
the best compression connection.
6.
Reposition tool for next crimp, if required. Unless
non-bowing dies are used, it is recommended that
the tool be rotated 90
°
for each adjacent crimp on
large splice connections.
