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