Adjust the variable blade speed only while the
machine is running. The dial (A, Fig. 6) sticking
out of the belt cover (right side) controls the
variable speeds between 66 FPM to 264 FPM.
Preset the height, which the arm stops when it
raises automatically. The height the arm raises
depends upon the piece you want to cut. The
limit switch is lowered or raised by loosening a
locking handle (A, Fig. 7). Tighten the locking
handle when the limit switch has been properly
adjusted.
The blade will stop after the material has been
cut, and the arm reaches its lowest position.
The arm will automatically rise to the preset
height.
Rate of downfeed is adjusted by turning the
downfeed knob on the control panel. Rate of
feed is important to bandsaw 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 speed and downfeed. The ideal chip
is thin, tightly curled, and warm to the touch.
Chips that range from golden brown to black
indicate excessive force. Blue chips indicate
extreme heat from too high a band speed, which
will shorten blade life. Thin or powdered chips
indicate insufficient downfeed rate.
A detailed explanation on feed rate can be found
in the enclosed "Guide to Band Sawing"
published by American Saw and Manufacturing
Company. Reprinted by permission.
