Crimp Tool
Adjustment of crimp force and height
Crimp force adjustment is done in the factory (120 – 180 N when unloaded). Tool
frame and jaws are connected that way, an optimal crimping result will be obtained
based on the hand force indicated above. In case the result (e.g. crimp height, pull-
out force, etc.) does not meet the requirements of the plug manufacturer, the following
reasons can be considered:
a) Normal wear of tool
Readjustment possible
b) Worn dies
Dies have to be replaced
The quality personnel is authorized to control and readjust these parameters as
described below:
- Unscrew the set screw by means of a screw driver
- Rotating the adjustment wheel anticlockwise, the crimp force increases
and the crimp height decreases ( + )
- Rotating the adjustment wheel lockwise, the crimp force decreases
and the crimp height increases ( - )
- When readjusting the hand force shall not exceed 180 N
- Before using the tool, the operator has to check the adjustment wheel being
firmly secured by the set screw
Maintenance
Keep the tool clean and properly stored when not in service. The joints need to be
regularly oiled and the circlips securing the bolts have to be always in place. Never
use abrasives or hard material to clean the jaws. Please contact the manufacturer
when the tool needs to be repaired or in case of readjustment problems.
