8.

Keeping the cable steady in the crimp, fully close the hand crimp tool until the ratchet
releases. Let the crimp tool open.

9.

After crimping remove the assembly. The process is then repeated for each crimp required.

TOOL MAINTENANCE

1.

Keep the tool clean and free from dirt and foreign matter. Ensure that all retaining pins and
clips are in place before use, and that signs of wear are not visible. If the pivots are worn,
the tool must be replaced, or crimp integrity will be compromised.

2.

Oil at all pivots and bearings using a light cycle oil.

3.

At regular intervals, check the crimp tool jaws for wear or damage, and inspect sample crimps
for form and function. Minimum pull-off forces (as shown in the previous table) should be
achieved when sample is tested. If forces are not achieved, calibrate the tool.

TOOL CALIBRATION

The operating force at the point shown should be 150N (15kg, 33lbs) min.

40mm

If adjustment of the tool becomes necessary due to pull-off forces not being maintained, the
following instructions should be followed.

1.

Remove Hex socket grub screw using a 2mm A/F Hex key.

2.

Using a screwdriver, turn the numbered wheel via the wheel adjustment screw. To increase

the pre-load (and therefore the crimp pull-off force), turn the screw until the next number is
shown. Even numbers are found by turning the screw clockwise, odd numbers are anti-
clockwise. Turn the screw until the required number is level with the Hex socket grub screw
hole.
