Changing the Drive Belt

Referring to Figures 22 and 23:

Disconnect the cut-off saw from its electrical power source.

1.Set the arm at the full horizontal position.

2.Open the drive belt cover to expose the V-beltand pulleys.

3.Loosen the belt tension adjust knob located in the rear under the motor (see Figure 23 for knob direction). Lift the motor upward to loosen the belt.

4.Remove the worn V-belt.

5.Put the replacement V-beltin the pulley position for the speed you require (refer to the Blade Speeds section on page 9).

6.Tighten the V-belt by turning the belt tension adjust knob (see Figure 23). The belt must be secure enough so it does not slip when the machine is running. Do not over tighten. This will cause premature wear on belt and pulley bearings.

7.Reinstall drive belt cover and install knob.

Replacing the Drive Motor

Disconnect the cut-off saw from its electrical power source.

Referring to Figure 24:

1.Remove the drive V-belt (see Changing the Drive Motor Belt above).

2.Open the motor junction box and disconnect the power cord wires from their terminals.

3.Remove four screws and washers (A) that secure the motor (B) to the mounting plate (C).

4.Installation of a new motor is a reversal of the above steps. Also, complete steps 6 through 8 in Changing Blade Speed (page 9) to complete tensioning of the V-belt to the correct tension — use a straight edge to be certain the motor pulley is correctly aligned with the speed reducer pulley.
