Blade Speed
The blade speed can be adjusted to 1700 or 3500
FPM. Speed adjustments are made by moving the
V-belt position on the motor and wheel pulleys.
Most woodcutting can be performed successfully
at the higher blade speeds. Slower blade speeds
generally produce better results when cutting
hardwoods, intricate curves, or when an excep-
tionally smooth cut is desired.
Use the chart below as a general guide to
blade speed:
Type of Cutting Operation
Blade Speed
(FPM)
Most Species of Wood 3500
Super Dense Hardwood 1700
Fast/Average Feed Rate 3500
Requires Slow Feed Rate 1700
Rough Edges Acceptable 3500
Requires Smooth Edges 1700
Quick, Production Cuts 3500
Detailed, Intricate Cuts 1700
To adjust the blade speed:
1. DISCONNECT BANDSAW FROM POWER!
2. Loosen the motor mount cap screws shown
in Figure 70, and rotate the motor to loosen
the V-belt.

3. Refer to Figure 71 to locate the correct V-belt
position for the desired blade speed and
move the V-belt to the indicated pulleys.

4. Rotate the motor to tension the V-belt, then
tighten the motor mount cap screws.
5. Check the V-belt tension by applying mod-
erate pressure between the pulleys (see
Figure 72). If deflection is not approximately
3
⁄4", re-tension the V-belt until it is.
