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.
