3. When the saw has completed about 1/3 of
the cut, increase the feed rate slightly and
allow the saw to complete the cut.
4. Keep the feed rate at the same setting and
begin a second cut on the same or similar
workpiece.
5. When the saw has completed about 1/3 of
the cut, increase the feed rate while
watching the chip formation until cutting is at
its most efficient rate (refer to “Evaluating
Cutting Efficiency” below). Allow the saw to
complete the cut.
6. The blade is now considered ready for use.
Setting Blade Speed
1. Consult the Speed and Pitch selection chart
on the front of the band saw. A chart is also
included on page 23 of this manual. Select
the speed setting for the material to be cut.
2. Model 8020FW: While the machine is NOT
running, move the gear selector lever
(Figure 15) to the required speed setting
(high or low).
Move the gear selector lever
only when the machine is NOT running, to
prevent damage to the gearbox.
3. Start the saw using the pushbutton.
4. Turn the variable speed handwheel (Figures
14 and 15) to the required speed. Turning
the handwheel clockwise increases speed.
Turning counterclockwise decreases speed.
Rotate the speed setting
handwheel only when the band saw is
running.
Evaluating Cutting Efficiency
The best way to determine whether the blade is
cutting efficiently is to observe the chips formed
by the cutting.
•
If the chip formation is powdery, then the
feed is much too light, or the blade is dull.
•
If the chips formed are curled, but colored –
blue or straw colored from heat generated
during the cut – then the feed rate is too
high.
•
If the chips are slightly curled and are not
colored by heat – the blade is sufficiently
sharp and is cutting at its most efficient rate.
