WARNING:
Failure to turn the saw off and unplug the saw from the
power source could result in accidental starting causing
possible serious injury.
ADJUSTING DROP FOOT
■
Loosen the drop foot lock knob.
See Figure 4, page 9.
■
Center the drop foot around the saw blade to the desired
position.
■
Tighten the drop foot lock knob.
ADJUSTING BLADE TENSION
See Figure 12.
■
Turn off and unplug the saw from the power source.
WARNING:
Failure to turn the saw off and unplug the saw from the
power source could result in accidental starting causing
possible serious injury.
■
Turning the blade tension knob clockwise decreases (or
loosens) blade tension.
■
Turning the blade tension knob counterclockwise
increases (or tightens) blade tension.
Note:
Adjustments to blade tension can be made at any
time.
Fig. 12
ADJUSTMENTS
Check tension by the sound the blade makes when plucked
like a guitar string. This method of adding tension to the blade
can be developed with practice and requires knowing your
scroll saw.
■
Pluck the back straight edge of blade while turning
tension adjusting knob. Sound should be a musical note.
Sound becomes less flat as tension increases. Sound
decreases with too much tension.
Note:
Be careful not to adjust blade too tight. Too much
tension may cause the blade to break as soon as you start
cutting. Too little tension may cause the blade to bend or
break before the teeth wear out.
OPERATION
BASIC OPERATION OF THE SCROLL SAW
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.
Note:
After the saw is turned
ON
, a hesitation before blade
movement is normal.
CUTTING PROCEDURES
■
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.
■
Plan the way you will hold the workpiece from start to
finish.
■
Keep your hands away from the blade. Do not hand hold
pieces so small your fingers will go under the blade guard.
■
Hold the workpiece firmly against the saw table.
■
The blade teeth cut material only on the down stroke.
■
Use gentle pressure and both hands when feeding the
work into the blade. Do
not
force the work.
■
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.
■
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.
■
To get accurate cuts, compensate for the blade's
tendency to follow the wood grain as you are cutting
wood.
■
Use extra supports (tables, saw horses, blocks, etc.)
when cutting large, small or awkward workpieces.
■
Never use another 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. Workpieces must not
twist, rock or slip while being cut.
