2. Align the drive roll removal tool (P/N

931-0100) over the ats 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 screw until tight.

Figure 3

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

Insulated Drive Roll Kits

Used to prevent preheating of the wire which may soften it and clog the liner.

This picking up of current at the drive rolls rather than at the contact tip is

usually not a problem unless using too large of a contact tip or excessively

oxidized aluminum wire.
