OPERATION MANUAL
5.6 SELECTING SPEEDS
This band saw has operating speeds of 20, 29, or 50
MPM. The speed can easily be adjusted by changing the
V-belt placement. Figure 5.9 shows an illustration of each
pulley belt combination, and the list below shows the
blade speeds in meters per minute.
Position 1
will have a blade speed of 20 m/min
Position 2
will have a blade speed of 29 m/min
Position 3
will have a blade speed of 50 m/min
To change the blade speeds:
1. DISCONNECT THE BAND SAW FROM THE POWER!
2. Open the belt drive cover (Fig. 5.10)
3. Loosen the V-belt tension hex screw to allow the
motor to pivot ( Fig. 5.11)..
4. Raise the motor to relieve the belt tension and
position the belt in the desired pulley alignment.
5. Release the motor and let the motor weight tension
the belt.
6. Position the V-belt tension hex screw back against the
frame of the band saw.
