CUTTING CIRCLES
1. Adjust the blade guard assembly to 1/8” above the
workpiece.
2. Use both hands while feeding the work into the blade.
Hold the workpiece firmly against the table. Use gentle
pressure. Do not force the work. Allow the blade to cut.
3. The smallest diameter circle that can be cut is deter-
mined by the width of the blade. For example, a 1/4”
wide blade will cut a minimum diameter of approxi-
mately 1-1/2”.

BLADE SELECTION
Blade teeth are sharp. Use care when handling a saw blade.
There are a variety of different types of bandsaw blades on the market to suit various cutting applications. The accom-
panying “Blade Selection” chart is provided as a general reference tool; your results may vary based on usage, expe-
rience and personal preference. Ask your local tool dealer for suggestions for 80” bandsaw blades in 1/8” to 1/2”
widths, based on what is available in your area.
Do not cut ferrous metals with this bandsaw.
SELECTING BLADE SPEED
This bandsaw is equipped with 2 speed settings: High - 2710 Feet Per Minute (FPM) and Low- 1580 FPM, allowing you to
achieve better results by selecting a more appropriate blade speed based on the cutting operation being performed.
Some general guidelines to consider for selecting blade speed:
Some general guideline to consider when choosing band-
saw blades:
• Wider blades with coarse teeth are best suited to cutting
straight lines, re-sawing and for sweeping curves, but will
not turn tight corners. They will cut quickly and aggres-
sively but do have a tendency to bind (or get stuck in
the cut) if turned to sharply.
• Narrower, thinner blades with finer teeth will cut more
slowly but can turn much tighter corners for cutting
more intricate work.
Common causes of blade breakage:
• Poor guide bearing alignment and adjustment.
• Forcing or twisting a wide blade around a short radius.
• Feeding the workpiece too quickly.
• Dull teeth.
• Too much blade tension.
• Setting blade guard assembly too high above the work-
piece.
• Lumpy or improperly finished braze or weld on the
blade.
• Continuous running of blade when not cutting.
