lever located inside the
movable handle. Pressing up
on this lever will release the
ratchet, and the handles
should then easily open. The
jam or miscrimp can then be
removed.
Low Pull-off Force
This tool is supplied as new, set to the right preload force necessary to crimp the M225 series
contacts. However, over time, this force may fall off slightly. The tool can be adjusted to cater
for this wear and raise the preload force to give correct crimps.
If you need to carry out this procedure, Harwin recommend that you crimp a number of samples
before and during adjustment, until the pull-off force achieved exceeds the minimum values
shown on the first page of this instruction sheet.
Ensure that the crimp
tool is at the fully open
position.
Rotate the setting wheel to a different setting – the higher the number displayed, the higher the
preload force.
Release the link to lock the wheel in place.
If the wheel has been set to the maximum setting possible, then the tool is no longer capable of
achieving the minimum pull-off force and should be replaced.

Hold the hand tool as shown in the above figure and
