Craftsman 315.21636 Saw User Manual


 
This scroll saw is designed to cut wood, wood compo-
sition products, plastic, and nonferrous metals (alumi-
num, brass, copper).
GENERAL OPERATION
Please read and understand the following items
concerning your scroll saw before attempting to use
the saw.
There is a learning curve for each person who
wants to use this saw. During that period of time
it is expected that some blades will break until
you learn how to use and adjust the saw.
Allow the saw to cut material by guiding the
workpiece into the blade as it moves. Do not
force the work.
The blade teeth cut material only on the down
stroke.
You must guide the workpiece into the blade
slowly because the teeth of the blade are very
small and can only remove material on the down
stroke.
Scroll saw blades wear out and must be replaced
frequently for best cutting results. Scroll saw
blades generally stay sharp for 1/2 hour to 2
hours of cutting, depending on type of material
and speed of operation.
To get accurate cuts, be prepared to compen-
sate for the blade's tendency to follow the wood
grain as you are cutting wood.
In cutting wood, best results are achieved when
cutting wood less than one inch thick.
When cutting wood thicker than one inch, the
user must guide the workpiece very slowly into
the blade and take extra care not to bend or twist
the blade while cutting.
When choosing a blade to use with your scroll
saw, consider the following carefully:
Very fine, narrow blades should be used to
scroll cut in thin material 1/4 in. thick or less.
Most blade packages state the size or thick-
ness and type of material which that blade is
intended to cut. Package should also state the
radius, o_size of curve, which can be cut with
that blade.
Wider blades cannot cut curves as tight or
small as thinner blades.
Blades wear faster:
When cutting plywood and other laminates.
When cutting material thicker than 3/4 in.
When cutting hardwood.
When side pressure is applied to the blade.
ON/OFF KNOB WITH VARIABLE SPEED
See Figure 16.
Your scroll saw has an easy access On/Off knob with
variable speed.
Pull the knob out to turn ON the saw, and push
the knob in to turn OFF the saw.
Note: After saw is turned on, a hesitation before blade
movement is normal.
_IL WARNING: Never leave the saw unattended
until the blade has come to a complete stop to
prevent serious personal injury.

By turning the knob, the variable speed control
may be adjusted from the high speed of approxi-
mately 1600 SPM (Strokes Per Minute) to the
low speed of approximately 500 SPM Suggested
speeds are identified under Choice of Blade and
Speed, page 18. Turn the On/Off knob to the
right or clockwise to increase strokes per minute
and to the left or counterclockwise to reduce the
strokes per minute.
This motor has an electronic control that regulates the
speed and provides overload protection to the motor.
If the motor fails to start after about 2 seconds, push
the knob OFF and disconnect the saw from the power
source. Refer to the troubleshooting chart.
Note: If the internal overload protector has been
tripped, pushing the On/Off knob OFF will reset it.
