• Loosen the clamping collar screw using a 3/16" Allen wrench. The clamping collar screw is accessed from the bottom of the feed plate. It is the screw which is perpendicular to the feeding direction.

• Loosen the retaining screw, which is also accessed from bottom of feeder, using a 3/16" Allen wrench. Continue to loosen the screw until the feed plate can be easily pulled off of the wire feeder.

3. Loosen, but do not remove, the screw on the lower right face of the feed plate with a 3/16" Allen wrench.

4. Remove the screw on the left face of the feed plate. If changing from high speed (larger gear) to low speed (smaller gear), line the lower hole on the left face of the feed plate with the threads on the clamping collar. Line the upper hole with the threads to install larger gear for high speed feeder. If feed plate does not rotate to allow holes to line up, further loosen the screw on right face of feed plate.
