Changing Blade Speed
1. Disconnect the machine from the power
source.
2. Place saw arm in the horizontal position.
3. Loosen tensioning plate hex nut (A, Fig.10).
4. Open pulley cover (B, Fig. 10). Lift motor
with one hand while placing the belt (C, Fig.
10) on the desired pulley combination.
5. Tension belt by pressing down on the motor
while tightening hex nut (A, Fig. 10) until
finger pressure on the belt between the two
pulleys causes approximately 1/2" deflection.
Close pulley cover. Don’t over tighten the
belt.
6. Close pulley cover and connect to power
source.
The general rule for band saw blade speed is
the harder the material being cut, the slower the
blade speed. Reference Figure 11 for a guide to
blade speed for a type of material being cut.
Adjusting Blade Guides
1. Disconnect machine from the power
source.
2. Loosen knob (A, Fig. 12) and slide blade
guide assembly (B, Fig. 12), as close as,
possible without interference to the material
being cut. Tighten knob.
3. Loosen bolt (C, Fig.12) and slide blade
guide assembly (D, Fig. 12), as close as,
possible without interference to the material
being cut. Tighten bolt
Adjusting Blade Tension
1. Disconnect machine from the power
source.
2. Open blade cover and observe the position
of the blade on the wheel. If the blade is not
next to the wheel flange, adjust blade
tracking following the steps under "Adjusting
Blade Tracking".
3. If the blade is next to the wheel flange,
loosen the blade guide assembly lock knob
and hex head bolt (A & C, Fig. 12) and slide
the blade guide assemblies as far apart as
possible. Lock in place.
4. Depress blade. Finger pressure should
cause approximately .004" deflection. Turn
blade tension knob (B, Fig. 12) until the
proper tension is achieved. Re-position
guides for cutting material.
