Replacing V-Belt
1. Disconnect machine from power source.
2. Release blade tension by turning blade
tension handwheel clockwise.
3. Release belt tension by loosening the two
hex cap screws (A, Figure 19, the pivot bolt
is not shown in the photo). 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 and remove hex
nut, and washer (B, Figure 20).
5. Remove the wheel (C, Figure 21). If the
lower wheel does not come off easily you
may need to use a pulley puller to remove
the lower wheel.
6. Remove the old belt (D, Figure 21) and
install the new belt.
7. Reinstall the lower wheel and tighten the
hex nut.
8. Remove the wood block or support from
below the motor and adjust the belt tension.
See “Adjusting the Belt Tension.”
9. Set the blade tension. See “Adjusting Blade
Tension” on the previous page.
10. Check the blade tracking. See “Adjusting
Blade Tracking” on the previous page.
Adjusting Belt Tension
The belt comes adjusted from the factory. If
future adjustment is needed:
1. Disconnect machine from power source.
2. Set the belt tension by lightly pressing down
on the motor and tightening the hex cap
screw (A, Figure 19, the pivot bolt is not
shown in the photo).
Note: The weight of the motor should put
enough tension on the belt. You just want to
push down lightly to take up any slack.
