Drive Roll and Idler Rolls

General

The Python

®

gun comes standard with a knurled drive roll and a grooved

idler roll, which will handle both steel and aluminum wire with diameters from
.030-1/16 inch. Optional insulated V-groove drive rolls are also available for
aluminum wire if desired (see Optional Kits).

Drive roll tension is accomplished with a unique spring-loaded pressure
screw. The Python

®

comes from the factory with the pressure adjustment

screw preset.

NO ADJUSTMENT IS REQUIRED FOR ALL SIZES

AND TYPES OF WIRES

.

Drive Roll Installation/Removal

NOTE: Neither of the handles needs to be removed to access the Drive

or Idler Rolls.

1. Pull the Cam Lever away from the idler roll.

This will relieve the pressure against the
drive roll (as shown in Figure 1).

2. Align the Drive Roll Removal Tool (P/N

931-0100) over the flats of the drive roll (as
shown in Figure 2). Hold the gun with one
hand or on a table top, with the other hand
give the Removal Tool a quick snap-turn in
the CLOCKWISE DIRECTION.

3. Once the drive roll is loose, continue to spin drive roll in the clockwise

direction to remove the drive roll from the gun.

4. Install a new drive roll on the left-hand threaded shaft. The drive roll will

self-tighten when it is feeding wire.

Idler Roll Installation and Removal
(Reference Figure 3)

1. Using a slot type screwdriver, loosen idler screw, taking care not to lose

lock washer under idler roll.

2. Insert new idler roll and lock washer onto screw, insuring that idler groove

is toward top and lock washer is beneath.

3. Tighten.

NOTE: Lock washer must be under idler roll or it will not turn freely.
