B. Crimp Tools with an Insulation Crimp Adjustment
The insulation crimp part of the hand crimp tool has three positions:
• 1 for a tight crimp
• 2 for a medium crimp
• 3 for a loose crimp.
It is necessary to test each combination of a tool, a terminal lug, and a wire to find the correct
adjustment:
(1) Set the adjustment to the loose position.
(2) Put a terminal lug in the crimp jaw of the crimp tool.
(3) Push the end of the wire into the insulation grip of the terminal lug until it stops.
Make sure that:
• The insulation is not removed from the end of the wire
• The end of the wire insulation is against the forward end of the insulation grip of the terminal
lug
• The wire insulation does not go into the crimp barrel of the terminal lug.
(4) Crimp the terminal lug.
(5) Examine the insulation support.
(6) Bend the wire back and forward once to make sure that the wire does not come out of the
terminal lug.
