Adjusting Blade Speed
This machine equipped with mechanic variable speed
control device allow for variable blade speed.
Adjust the blade speed while the machine is running.
The dial sticking out of the motor cover (right side)
controls the variable speeds between 66-264FPM
(20-80MPM).
Rotate the governor (A) by following the level (B) in
the scale to get desired speed for cutting the work
piece
Adjusting Feed Rate
Rate of feed is adjusted by turning the cutting
pressure control knob on the control panel. Rate of
feed is important to band saw performance; excessive
pressure may break the blade or stall the saw.
Insufficient pressure rapidly dulls the blade.
Material chips or shavings are the best indicator of
proper seed and pressure. The ideal ship is thin,
tightly curled, and warm to the touch. Chips that range
from golden brown to black indicated excessive force.
Blue chips indicate extreme heat from too high a blade
speed, which will shorten blade life. Thin or powdered
chips indicate insufficient feed pressure.
Down-Bow Dampener
The dampener functions to produce a finer cut by
reducing the rate of bow descent as the blade nears
the table. The width of measurements of the blades
between inch size and mm size are slightly different.
This saw is equipped with inch size blade at the
factory. If the user did not get the inch type but instead
got a mm size blade, it is necessary to adjust the
dampener by turning the cap screw clockwise about
1/4 revolution, and also adjust the shut-off limit switch.
Otherwise, the saw bow will not automatically rise up
after completing the cut.
