OPERATION

WARNING:
Do not allow familiarity with tools to make you
careless. Remember that a careless fraction of a
second is sufficient to inflict severe injury.
WARNING:
Always wear eye protection with side shields
marked to comply with ANSI Z87.1. Failure to do
so could result in objects being thrown into your
eyes, resulting in possible serious injury.
WARNING:
Do not use any attachments or accessories not
recommended by the manufacturer of this tool.
The use of attachments or accessories not rec-
ommended can result in serious personal injury.
WARNING:
To avoid blade contact, adjust the blade guide to
just clear the workpiece. Failure to do so could
result in serious personal injury.
APPLICATIONS
You may use this tool for the purposes listed below:
 Scroll cutting and circle cutting of wood and wood com-
position products
 Relief cutting of wood and wood composition products
BASIC OPERATION OF THE BAND SAW
A band saw is basically a "curve cutting" machine that can also
be used for straight-line cutting operations like cross cutting,
ripping, mitering, beveling, compound cutting, and resaw-
ing. It is not capable of making inside or non-through cuts.
This band saw is designed to cut wood and wood composi-
tion products only.
Before starting a cut, lock the mobile stand and watch the
saw run. If you experience excessive vibration or unusual
noise, stop immediately. Turn the saw off, remove the switch
key, and unplug the saw. Do not restart until locating and
correcting the problem.
CUTTING PROCEDURES
 Hold the workpiece firmly against the saw table.
 Use gentle pressure and both hands when feeding the
work into the blade. Do not force the work; allow the
blade to cut.
 The smallest diameter circle that can be cut is determined
by blade width. A 1/4 in. wide blade will cut a minimum
diameter of 1-1/2 in.; a 1/8 in. wide blade will cut a mini-
mum diameter of 1/2 in.
 Keep your hands away from the blade. Do not hand hold
pieces so small your fingers will go under the blade guard.
 Avoid awkward operations and hand positions where a
sudden slip could cause serious injury from contact with the blade. Never place hands in blade path.
 Use extra supports (tables, saw horses, blocks, etc.) when
cutting large, small or awkward workpieces.
 Never use a person as a substitute for a table extension
or as additional support for a workpiece that is longer or
wider than the basic saw table.
 When cutting irregularly shaped workpieces, plan your
work so it will not pinch the blade. For example, a piece
of molding must lay flat on the saw table. Workpieces
must not twist, rock or slip while being cut.
When backing up the workpiece, the blade may bind in the
kerf (cut). This is usually caused by sawdust clogging the kerf
or when the blade comes out of the guides. If this happens:
 Wait until the saw has come to a full and complete stop.
 Place the switch in the OFF (O) position then remove the
switch key from the switch assembly. Store key in a safe
place.
 Unplug the saw from the power source.
 Wedge the kerf open with a flat screwdriver or wooden
wedge.
 Open front cover and turn the upper wheel by hand while
backing up the workpiece.
RELIEF CUTS
Relief cuts are made when an intricate curve (too small a
radius for the blade) is to be cut. Cut through a scrap sec-
tion of the workpiece to curve in pattern line then carefully
back the blade out. Several relief cuts should be made for
intricate curves before following the pattern line as sections
are cutoff of curve "relieving" blade pressure.
