WARNING
Disconnect band saw from power source when changing
or adjusting blades. Wear leather gloves when handling
band saw blades. Never wear gloves when operating saw.
This band saw has two blade speeds.
•
For the high speed 3340 ft/min, the belt should be fitted
to the rear pulley on both the motor and band wheel
(see Figure 18).
• For the low speed 1620 ft/min, the belt should be fitted
to the front pulley on both the motor and bandwheel
(see Figure 18).

BLADE SELECTION
• Blades vary depending on type of material, size of
workpiece and type of cut that is being performed.
• Characteristics that make blades different are width,
thickness and pitch.
BLADE WIDTH
• Width of blade describes distance from tip of a tooth to
back of blade.
• Width of blade affects rigidity of blade. A wider blade
wanders less and produces a straighter cut.
• Width of blade also limits the smallest radius which can
be cut. A ¼" wide blade can cut about a ½" radius.
BLADE THICKNESS
• Blade thickness describes the distance between sides
of blade. A thicker blade has more rigidity and stronger
teeth.
• A narrow thick blade is used to cut curves while a wide
thin blade is used to make long, straight cuts.
BLADE PITCH
• Pitch describes number of teeth per inch or tooth size.
A blade with more teeth per inch produces a smoother
cut.
• The type of material being cut determines number of
teeth which should be in contact with work.
• For soft materials, the proper blade has between 6 to 8
teeth per inch.
• When cutting hard materials, where shocking is more
detrimental, use a blade with 8 to 12 teeth per inch.
• There should always be at least three teeth in contact
with cut to avoid shocking blade.
• Blade shocking occurs when pitch is too large and blade
tooth encounters too much material. This can strip teeth
from blade.
• Blade manufacturers are prepared to supply information
about blades for specific applications.
TYPE OF CUT
• Contour cutting is done by guiding workpiece freehanded
to produce curved shapes.
• Beveled cutting is done by tilting saw table and using
proper work guide method.
• Regardless of which work guiding method is used, a
workpiece which overhangs table by more than 5"
needs proper support.
CONTOUR SAWING
• When contour sawing, use both hands to keep work
piece flat against table and guided along desired path.
• Avoid positioning hands in line with blade. If hands slip,
they could contact blade.
• Try to stand to front of the saw and use hands over the
portion of table which is to right of blade and before cut.
• Cut small corners by sawing around them. Saw to
re move scrap until desired shape is obtained.
BEVEL CUTTING
Refer to Figure 14.
For bevel cuts, the table tilts 0 through 45 degrees.
Perform bevel cutting by tilting table to desired degree.
• Unlock table by loosening wing nut located on the
backside of the unit.
• Tilt table to desired position.
• Lock table in position by tightening wing nut.
MITRE GAUGE
• Use mitre gauge (optional accessory) for securing and
holding workpiece at desired angle to produce angled
cuts. Use scale to adjust gauge to desired angle.
WARNING
Never use mitre gauge and rip fence at the same time.
The blade might bind in the workpiece. Operator could be
injured and/or workpiece could be damaged.
BLADE CLEANING BRUSH
• Make sure that brush is in contact with blade to properly
remove foreign particles from drive wheel.
