GENERAL INFORMATION
The Z22-020 Hand Crimp Tool consists of a ratchet mechanism hand tool and a set of jaws. The
jaws comprise of upper and lower crimp dies.
The contact is correctly crimped when the tool is free to open at the fully closed position, i.e. when
the ratchet releases.
CRIMPING PROCEDURE
1.
Ensure that the wire to be crimped is within the specified range of sizes for the contact and
the crimp tool. Failure to use the specified wire size will result in poor quality crimps and
possible tool damage.

2.
Strip the wire insulation to the dimensions shown below. Care should be taken to avoid
cutting or displacing the conductors. If the conductors are displaced, they may be re-aligned
with a gentle twist.
1.0mm max (M22-304/5)
1.5mm max (M22-306/8)
Ø1.4mm max
3.
Make certain that the hand crimp tool is in the fully open position, and that the jaws are free
from dirt and debris.
4.
If the socket is on a reel, break or cut off a contact from the strip of bandolier.
5.
Place the contact into the correct crimp cavity in the fixed jaw. The markings on the jaw
indicate the correct crimp cavity according to the wire size being used. The orientation of the
contact is with the crimp end uppermost, with the open side of the crimp facing towards the
moving jaw.
6.
Partially close the crimp tool until the wire stop comes across the face of the fixed jaw.
7.
Take the pre-stripped wire and insert it into the contact so the conductors and insulation are
positioned in the crimp. The conductors should be touching the wire stop.
