Adjusting the Handle Pre-Load
The tool is calibrated at the factory to the optimum pre-load required to achieve a proper crimp. It may
become necessary, over the life of the tool, to adjust the handle pre-load force.
Follow the steps below to adjust the crimping force of the hand tool to obtain proper crimp parameters
(Figure 5):
• Remove 2 mm locking
screw from the
adjustment wheel using
TORX head wrench.
• Using a small
screwdriver, turn the
adjustment wheel to the
next marked position.
• The tool uses an
eccentric axle linkage
mechanism. To increase
the handle pre-load,
move the wheel
clockwise to the next
highest odd number, or
counterclockwise to the
next highest even number.
• Turn the wheel until the desired number is located over the 2 mm tapped hole.
• Replace the 2 mm locking screw, aligning the nearest notch in the setting wheel.
• Check the crimp against the specifications, and conduct a pull test after the tool handle pre-load force
is adjusted. Repeat the steps until the desired crimp performance is obtained.
