Turn drive belt adjustment crank to position both side drive belts against sides of box (Figure 11-1).

11.2 Box Height Adjustment

Turn height adjustment crank to position upper taping head onto box. Turn clockwise to lower head, counterclockwise to raise head. Upper taping head must contact and hold top box flaps closed

(Figure 11-2).

Figure 11-1

The top flap compression rollers have an adjustable slide mounting to provide side compression through the full range of box widths.

Manually move box forward so front of box is aligned with top flap compression rollers.

11.4 Changing the Tape Leg Length

Taping heads are preset to apply 70mm [2.75 inches] long tape legs. To change tape leg length to 50mm [2.0 inches], refer to Instructions below and also to Manual 2, "Removing Taping Heads Procedure - Changing the Tape Leg Length".

11.5 Run Boxes to Check Adjustment

Push electrical switch "On" (I) to start drive belts.

Move box forward under upper taping head until it is taken away by drive belts. If box is hard to move under head or is crushed, raise head slightly.

If the box movement is jerky or stops under the upper head, move the side drive belts in slightly to add more pressure between the box and drive belts.

Important – If drive belts are allowed to slip on box, excessive belt wear will occur.
