Pneumatic Crimping Head Assembly 314991-1
408-4198
When crimped, the wire size will appear on both sides
of the terminal wire barrel. The wire size appearing on
the crimped wire barrel should always agree with the
wire size stamped on the terminal tongue.
4. CRIMPING PROCEDURE
Strip the wire using the appropriate strip–length
dimension provided in Figure 2. Do NOT nick or cut
the wire strands. Proceed as follows:
3. HEAD INSTALLATION AND REMOVAL
NOTE Crimping heads are coated with a preservative to
prevent rust and corrosion. Wipe this preservative
i
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
the crimping head.
DANGER Do NOT operate tool without having crimping
head installed and lockscrew tightened.
1. Remove assembly pins from mounting lugs as
shown in Figure 1.
2. Pull toggle arm forward and insert toggle lever
of crimping head all the way into hole in toggle arm
until it snaps in place. See Figure 1.
3. Align holes in crimping head links with holes in
mounting lugs.
4. Insert assembly pins.
CAUTION Be sure assembly pins are fully inserted or
damage to tool or pins will occur.

1. Check that wire size stamped on terminal
corresponds with the wire size stamped on the
crimping head link.
2. Place terminal in dies. See Figure 3. Bottom of
terminal tongue should face top of tool and
terminal barrel should rest against locator.
3. Insert stripped wire in terminal until end of wire
conductor butts against locator as shown in
Figure 3.
5. Connect pneumatic tool to an adequate air
supply between 585–690 kPa [85–100 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
the crimping head.
1. Remove assembly pins.
2. Lower head away from mounting lugs, twist
