Position a new DRIVE MOTOR BELT over the DRIVE MOTOR and FRONT ROLLER PULLEYS taking note to properly align the ribs within the grooves of the PULLEYS. Relocate the FRONT ROLLER back into operating position.

Step 7

Use a hex key wrench to tighten the TENSIONING SCREWS and WASHERS at the REAR ROLLER by ALTERNATELY turning the SCREWS clockwise an EQUAL number of times each until the STRIDING BELT is snug, but not overstretched, against the REAR ROLLER.

Step 8

Check the tension of the DRIVE BELT using a BELT TENSIONING GUAGE. (Belt tension=100 lb+/-5 lb). The DRIVE BELT tension can be adjusted by loosening or tightening the LOCK NUT of the TENSIONING BOLT located next to the LIFT ACTUATOR.

CHECKING THE DRIVE BELT PULLEY ALIGNMENT:

It is a good practice to check the alignment of the DRIVE MOTOR BELT PULLEY and the FRONT ROLLER PULLEY whenever servicing or replacing the DRIVE MOTOR BELT. With the power switch OFF and the machine unplugged from the electrical outlet, lay a straightedge flat against the outside of the FRONT ROLLER PULLEY and the DRIVE MOTOR PULLEY. The flat faces of the two PULLEYS should be in-line (coplanar). If the PULLEYS are not in-line, loosen the two DRIVE MOTOR PULLEY SET SCREWS and adjust the DRIVE MOTOR PULLEY on the MOTOR SHAFT accordingly. Tighten the SET SCREWS to secure the PULLEY into position.
