Chapter 4: Mixer Assembly

Belt Tension Adjustment

Adjustment of belt tension is achieved by tightening the hex nuts located on the four jack screws of the
motor base.

1. Adjust the motor base equally at all four jack screws to maintain the shaft alignment.

2. When the V-belt tension is correct, tighten the top nut on the jack screws to lock the motor base in

position.

NOTE:

Refer to the

Mixer Specifications, page 19

for belt drive and belt tensioning details.
