Over--tightening the cam setscrew may damage

4. Properly align tool holder ratchet pawl with the

cam teeth and push tool holder onto power unit so

that it passes over the friction ring on the power

unit piston. See Figure 2.

5. Slide power unit locking ring toward tool holder

until it butts against the stop ring on the power unit.

Then turn ring clockwise to engage threads on the

bottom of the tool holder. Tighten locking ring to

fully secure the tool holder.

When tool holder is properly installed, the locking

ring should be butted against the stop ring, and

threads of the tool holder should not be visible. If

not properly installed, check that correct

combination of cam and tool holder is used and

that they are aligned properly.

6. Rotate the tool holder one full turn in each

direction and note that the power unit locking ring

rotates with the tool holder.

To avoid personal injury, periodically check that

locking ring is tightly securing the tool holder.

After installation, ALWAYS ensure that the tool

holder pivot pins are fully tightened to avoid

personal injury or damage to the tool.

Removal is the reverse of installation.

3.2. Crimp Head Adapter and Crimping Die Installation

Refer to the instruction sheet packaged with the crimp

head adapter for the particular product to be crimped.

4. CRIMP HEIGHT ADJUSTMENT

The tool holder features an adjustable eccentric and a

ratchet mechanism with a range of settings. The

position of the pawl ensures that the tool completes

the cycle. The eccentric controls the amount of cam

pressure exerted on the crimping dies during the

crimping procedure. Although the ratchet is preset

prior to shipment, it is important that you verify the

crimp height. Also, general use and subsequent wear

may cause the tool to go out of adjustment. It is

recommended that the crimp height be inspected, and

adjusted, if necessary, on a regular basis by quality

control personnel.

1. Connect pneumatic tooling 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 instructions packaged

with the pneumatic tooling assembly.

2. Place a contact in the crimp nest and place a

properly prepared wire of the correct size into the

wire barrel.

3. Place a .025--mm [.001--in.] shim between the

crimping dies where the dies bottom against each

other.
