wire, the pneumatic tool is activated to crimp the
product to the wire.
3. HEAD INSTALLATION AND REMOVAL
NOTE
i
Crimping heads are coated with a preservative to
prevent rust and corrosion. Wipe this preservative
from the crimping head, particularly from the
crimping surfaces.
3.1. Installation
DANGER
To avoid personal injury, ALWAYS disconnect
pneumatic tool from air supply before installing or
removing the crimping head.
4. WIRE SELECTION AND PREPARATION
4.1. Wire Selection
Select wire for the terminals and splices according to
Application Specification 114--2121.
4.2. Wire Preparation
If using stranded copper wire, strip the wire to
dimensions shown in Figure 2. DO NOT nick wire
strand or use wires with nicked or missing conductor
strands.
NOTE
i
Do not strip film- insulated copper or
film- insulated aluminum wire.
DANGER
DO NOT operate pneumatic tool without the
proper crimping head installed. After crimping
head is installed, make sure that the quick pins
are FULLY tightened to avoid personal injury or
damage to the tool.
1. Remove quick pins from tool holder. Refer to
Figure 1.
2. Insert crimping head into tool holder as shown in
Figure 1.
3. After crimping head is properly aligned, insert
and tighten quick pins provided with the tool holder.
See Figure 1.
NOTE
i
Tyco Electronics recommends using LOCTITE{
242 removable threadlock, or equivalent, to
prevent the quick pins from loosening.
4. Connect pneumatic tool to an adequate air
supply between 620--690 kPa [90--100 psi]. For
specific information on air line requirements and air
hose installation, refer to the customer manual
packaged with the pneumatic tooling assembly.
3.2. Removal
DANGER
To avoid personal injury, ALWAYS disconnect
pneumatic tool from air supply before removing
crimping head.
Remove quick pins from crimping head; then remove
crimping head from tool holder.

5. CRIMPING PROCEDURE
DANGER
To avoid personal injury, ALWAYS keep fingers
clear of crimping jaws when operating the tool.
Never place anything within the crimping jaws
except terminals and splices.
5.1. Terminal Crimping Procedure
1. Open crimping jaws by squeezing rollers
together simultaneously; then position the terminal
in the crimping chamber on the lower jaw, as
shown in Figure 3, Detail A. The terminal is
properly positioned when the back of the terminal
is facing the upper jaw and the wire barrel is
against the locator.
2. After terminal is properly positioned, release
rollers to allow crimping jaws to spring shut,
holding terminal in place.
3. Insert stripped wire into terminal wire barrel until
the end of the conductor butts against the locator.
4. Activate the tool to complete the crimp. Open
crimping jaws by squeezing the rollers together
simultaneously; then remove crimped terminal.
