Replacing the V-Belt

Disconnect machine from power source before making any adjustments.

1.Release blade tension as described in the Blade Tension section.

2.Release belt tension by loosening the two hex cap screws (A, B, Fig. 25). The pivot bolt (B) is not visible.

3.Raise the motor and place a block of wood under the motor to take the tension off the belt.

4.Open the lower wheel door (C, Fig. 26) and remove the hex nut and washer (D, Fig. 26).

5.Remove the wheel (E, Fig. 27). If the lower wheel does not come off easily you may need to use a pulley puller to remove it.

Note: If you are doing a pulley alignment only, skip Step 6.

6.Remove the old belt (F, Fig. 27) and install the new belt.

7.Since the wheel is still off, this is the most convenient time to check the wheel and motor pulley alignment. Jump to the Pulley Alignment procedure (following page) at this time. At the conclusion you will be redirected back here.

8.Reinstall the lower wheel, hex nut and washer and tighten the hex nut.

9.Remove the wood block or support from below the motor.
