Tensioning the Drive Belts.
The tightening and loosening of the Drive Belts is done by way of moving the Air End vertically either towards or
away from the Motor. To adjust the Belt tension, simply:
1. loosen the (4) Slider Bolts holding the Air End in place
2. tighten (turn clock-wise) the Adjusting Nut on the Top of the Belt Tensioner Screw
3. re-torque the (4) Slider Bolts to 150 ft lbs (203.4 Nm)
Belt tensions for both new and older Belts are noted below.
