1. INTRODUCTION
1.1Hand Tool Function
The HT-0110 is a manually operated hand tool designed for crimping loose piece (individual)
Crimp-to-Wire Male Pin terminals to wire sizes of 22-26 AWG.
1.2Physical Description
The major components that make up the HT-0110 are identified in Figure 1. These include a
frame, lever, tooling, tooling holders and a terminal holder. The heart of the hand tool is the
tooling. The tooling performs the crimping operation and is divided into top and bottom
component groups. The top group consists of those parts which remain stationary with the
frame. The bottom group contains those parts that move with the lever. The HT-0110 is
equipped with tooling for crimping two different ranges of wire sizes..
1.3Principles of Operation
The lever attaches to the lower tooling and provides the mechanical advantage to generate
the necessary crimping pressure. As the lever is closed, a ratchet mechanism engages to
prevent the lever from opening until the crimping cycle is complete.
When the lever is pulled closed, the lower tooling and terminal are pushed up against the
upper tooling. The crimp is formed between the wire and insulation barrel anvils and the wire
and insulation crimpers.
Once closed, the ratchet releases and allows a spring to pull the lever open

CAUTION
If the terminal and the tooling are not compatible, damage to the tooling could result. If you
wish to use a terminal with a part number other than the one that was ordered for the HT-
0110 check with your distributor to be sure that the new terminal number is compatible with
your hand tool.

2. OPERATION
2.1Operating Procedures
WARNING
To prevent hand injury, keep fingers from between the upper and lower tooling and
from between the lever and handle when closing hand tool.
1. Hold the hand tool so that the lever is on the left. With your index finger, push and hold
the terminal holder in its forward position (see Figure 2).
NOTE
When inserting a terminal into the terminal holder you will notice a slight drag (interference)
on the terminal. The drag is caused by the spring ball plunger (see Figure 13 item no. 21)
applying downward pressure on the pin end of the terminal.
This downward pressure helps to orient and hold the terminal in the terminal holder until
crimped.
2. Insert the pin end of the terminal, with “U” shaped barrels
up, into the terminal holder and against the pin shoulder.
While holding the terminal against the shoulder, release
the terminal holder. This ensures that the terminal
remains in the proper position while moving over the
anvil.
Figure 2. Positioning Terminal for
Crimping

Instruction manual HT110 www.foehrenbach.be
Date : Octobre 2007 Documentrev. : 4 Page : 6 / 13/
3. While grasping the lever and the handle portion of the frame, insert a wire so that the end
of the insulation is centered between the wire barrel and the insulation barrel of the
terminal (see Figure 3). An alternate method is to position the end of the insulation
against the tonker (see Figure 13, item no. 2) which protrudes from between the crimpers
(3 & 4). Then close the hand tool lever completely. This will crimp the terminal to the
wire(s).
4. Release the lever to open the hand tool and remove the crimped terminal by lightly pulling
straight out on the wire.
CAUTION
The crimp height for this hand tool was factory adjusted. Any changes to this crimp
height adjustment could cause a defective crimp or damage to the tooling.
2.2Terminal Inspection
The crimped terminal should be inspected to ensure that the tooling is correctly aligned and
that the wire was correctly inserted. Make the following visual checks (see Figure 4).
NOTE
If inspection of the crimped terminal reveals any defects, the terminal has not been properly
crimped and should be discarded.
•Check that all wire strands were crimped within the wire barrel.
•Check that the end of the wire insulation lies between the insulation and the wire barrel.
•Check that the bellmouth(s) were formed correctly.
•Check that the wire barrel seam is even and tightly closed.

Next, obtain a crimp height micrometer and measure the areas of the terminal shown in
Figure 5. If the crimp heights do not meet the specifications listed in Section 1, Paragraph
2.4, refer to Section 5 for proper adjustment procedures.
