OPERATION

WARNING:

Do  not  allow  familiarity  with  tools  to  make  you  care-
less. Remember that a careless fraction of a second is 
sufficient to inflict serious injury.

WARNING:

Always wear safety goggles or safety glasses with side 
shields  when  operating  power  tools.  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  recommended  can 
result in serious personal injury.

WARNING:

To avoid blade contact, adjust the blade guide assembly 
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  

composition 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 
resawing. 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, 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 

minimum 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

  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  
section 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.
