on the bottom of the tool holder. Tighten locking

ring to fully secure the tool holder.

When tool holder is properly installed, the tool

holder 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 assembly of cam and tool holder is being

used and that they are aligned properly.

6. Rotate the tool holder one full turn in each

direction and note that the tool holder locking ring

rotates with the holder.

To avoid personal injury, periodically check that

tool holder 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.

7. For instructions on installing the crimping head

(and, if applicable, die set), refer to the instruction

sheet packaged with the head.

4. CRIMP HEIGHT ADJUSTMENT

The tool holder assembly 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

head jaws or dies during the crimping procedure.

Although the ratchet is preset prior to shipment, it is

important that the crimp height be verified. 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 tool to an adequate air

supply between 620 to 690 kPa [90 to100 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 on the crimp nest and place a

properly prepared wire of the correct size into the

wire barrel.

3. Place a 0.025--mm [.001--in.] shim between the

crimping jaws where the jaws bottom against each

other.

4. Slowly crimp the contact onto the wire until the

crimping jaws or dies bottom on the shim. Check

that the ratchet releases after the jaws or dies

bottom.

To avoid personal injury, DISCONNECT TOOL

FROM AIR SUPPLY before adjusting the pawl

position. After the adjustment, ALWAYS ensure

that the tool holder pivot pins are fully tightened

to avoid personal injury or damage to the tool.

5. If the ratchet releases before the jaws or dies

bottom, loosen the three securing screws (see

Figure 1), remove the eccentric adjustment screw

and rotate the eccentric clockwise to a higher

setting. Repeat as required.

If the ratchet does not release and the tool will

not return, slowly actuate the tool until the force

of the cam teeth is off the pawl, then push on the

pawl with a small screwdriver until the pawl is

released from the teeth, release the tool handle

and allow the tool to return. See Figure 3.
