basic scroll saw operation
NOTE: Make certain set screws in blade holders are
tight prior to each use of the scroll saw
WARNING: NEVER OPERATE WITHOUT TABLE
INSERT IN PLACE.
This scroll saw accepts a wide variety of blade
widths and thicknesses: 5" to 6" isrtgih plain end
type blades and 5" length pin type blades The blade
size (thickness and width) and the number of teeth
per Inch are determined by the type of material and
the smaiiest radius being cut
NOTE: Use wider blades to achieve straightest cuts
A s c r o t i s a w i s basically a "curve cutting" machine, it
can also be used for straight-line cutting operations
such as cross cutting, ripping, mitering, beveling,
and compound cutting.
Using the proper blade for the material and
thickness being cut will help the operator to follow
pattern lines. (Use wider blades to achieve the
straightest c u t s ) Blade teeth should always point
down.
When a blade is dull, or when insufficient blade
tension is being used, the blade may have a
tendency to twist or break
To minimize blade breakage and to produce more
accurate results, be sure the blade is not forced into
the workpiece. Too much pressure should not be
applied on the wood as it is fed into the blade.
Steady, even pressure will produce more uniform,
cleaner cutting with less blade breakage.
Loosen blade tension knob when scroll saw is not in
use., Follow procedure to tension blade before use.
The scroll saw has the capability of inside cutting
(piercing), Pin-type blades are recommended when
inside cutting as the best type of blade to use for
maximum performance Driil an over-sized hole in
scrap section of workpiece Locate two (2) blade
holder keys among loose parts Position each key
over one installed blade holder to secure holder
while installing blade through workpiece. Release

INSTALLATION-GETTING TO KNOW YOUR
SCROLL SAW) Remove two (2) blade holder keys
and store for future use.
Plain-end blades can be used for inside cutting.
Follow the procedure for pin-type blades, and
loosen set screws in upper and lower blade holders
using set screw wrench When installing blade in
blade holders, tighten set screws with wrench
Use caution when cutting off material which is
irregular in cross section which could pinch the
blade before the cut is completed A piece of
molding for example must lay flat on the table and
not be permitted to rock while being cut
Use caution when cutting off round material such as
dowel rods, or tubing They have a tendency to roll
while being cut causing the blade to "bite" Always
use a “V" block, or ciamp round materia! to a miter
SAWING/SCROLLING
1 Adjust the guard to just contact the top of the
workpiece
2, Use both hands while feeding the work into the
blade Hold the workpiece firmly against the
table Use gentle pressure, and do not force the
work, but ailow the blade to cut
3 Avoid putting side loads on the blade during
cutting to keep cut square to tabie
NOTE; When very sharp curves are to be cut, narrow
blades should be used Remove blade clips when
using narrow blades
BEVEL SETTING/CUTTING
WARNING: TO AVOID RUNNING THE MITER
GAUGE INTO THE GUARD, ALWAYS SET THE
BEVEL ANGLE TO THE RIGHT AS SHOWN
Loosen bevel lock knob and tilt housing of saw to
the desired angle degree by reading bevei scales
Adjust the guard to just contact the top of the
workpiece.. Perform bevel cuts by feeding
workpiece into blade without a guide or using the
