Band Saw Settings
2.1
Selecting the Correct Blade Speed
This band saw can be operated at two different speeds. By changing the V-ripped belt on the pulleys either 370 m/min (20.2
fps) or 800 m/min (43.7 fps) are possible. The band saw blade speed most suitable for the job at hand should be found by
making trial cuts in a piece of scrap wood.
We recommend:
800 m/min for all timber
370 m/min for hardwoods, certain plastics and NF-metals.
Change of Saw Blade Speed
Slacken the V-ripped belt with the crank located at the side of the lower wheel
housing. Both the lower band saw wheel and the motor pulley are 2-stepped,
Place belt on either front or rear V-grooved step on both pulleys (see also label
in the lower door). Adjust belt tension pulley position on its shaft accordingly,
then tighten the belt.
