Changing Blade Speeds
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.
Semi-Automatic Arm
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.
Automatic Shut-Off
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.
Adjusting Feed Rate
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.
