BASIC SCROLL SAW OPERATIONS

Follow these instructions for operating your scroll station to get the best
results and to minimize the likelihood of personal injury.
To avoid being pulled into the saw blade
WARNING
!
DO NOT WEAR:
loose fitting gloves
loose clothing
jewelry
DO:
tie back long hair
roll long sleeves over elbows
◆
The saw does not cut wood by itself. You allow the saw to cut wood
by guiding the wood into the blade as it moves.
◆
The blade teeth cut ONLY on the down stroke.
◆
The drop foot should always be lowered until it just rests on top of
the workpiece.
◆
You must feed the wood into the blade slowly because the teeth of
the blade are very small and they can only cut wood when they are
on the down stroke. The blade will flex backwards when applying
feed pressure. Too much feed pressure will cause blade breakage.
Let the blade do the work.
◆
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 the saw and receive the greatest
benefit from the blades.
◆
Best results are achieved when cutting wood less than
25 mm thick.
◆
When cutting wood thicker than 25 mm, the user must feed the
wood very slowly into the blade, increase blade tension and take
extra care not to bend or twist the blade while cutting in order to
maximize blade life.
◆
Teeth on scroll saw blades wear out and blades must be replaced
frequently for best cutting results. Scroll saw blades generally stay
sharp for 1/2 hour to 2 hours of cutting.
◆
To get accurate cuts, be prepared to compensate for the blade's
tendency to follow the wood grain as you are cutting.
When choosing a blade to use with your scroll saw consider the following
carefully:
◆
Choose a blade that allows at least 3 teeth to be in contact with the
workpiece at all times.
◆
Very fine, narrow blades should be used to scroll cut in thin wood
(6 mm thick or less).
◆
To cut thicker wood, use wider blades with fewer teeth per mm.
◆
Most blade packages state the size or thickness of wood for which
that blade is intended to cut, and the radius (size of curve) which
can be cut with that blade.
◆
Wider blades can't cut curves as tight or as small as thinner blades.
◆
This saw uses 127 mm long, Pin-or Plain-End type blades without
adapter (See RECOMMENDED ACCESSORIES).
◆
Blades wear faster when:
(1) cutting plywood, which is very abrasive,
(2) sawing wood which is thicker than the 19 mm blade stroke,
(3) sawing hardwood or

OPERATION
(4) side pressure is placed on the blade.
Your new scroll saw accepts 127 mm Pin-End blades or 127 mm Plain-
End blades (See RECOMMENDED ACCESSORIES ).
The blades can be used in either 0° (forward facing) or 90° (to the left)
position. In order to change sawing direction.
1. Remove bolt from upper and lower blade holders.
2. Remove blade holders and rotate 90° so the blade slot faces the
left side of the saw.
3. Reinstall bolts and tighten securely.
Always disconnect plug from the power source before

making any adjustments or changing any accessory.

REMOVING AND INSTALLING BLADES

1. Release blade tension by lifting up the quick release tension lever
(Figure 10) and turning counterclockwise.
2. Open easy access door (Figure 1 (L)) and loosen the blade wing
knobs (Figure 8 (A)) on the upper and lower blade holders. Remove
blade from the upper and lower blade holders by pulling forward on
blade and then lifting the blade through the access hole in the table.
Slight downward pressure against the upper holder may be helpful .
Table insert may be removed for better access. Table insert
NOTE
must be replaced before operating the saw.
3. Install the blade by inserting one end of the blade through the
access hole in the table.
4. FOR PIN-END BLADES: hook the blade pin in the pin recess in the
lower blade holder. Slide the top blade pin into the pin recess of the
upper blade holder. You may need to press down lightly on the
upper blade holder to install the blade.Check that the pins are
properly located in the blade holders.
FOR PLAIN-END BLADES: Install the blade by inserting one end
of the blade through the access hole in the table and centering the
blade in the blade slot in the upper and lower blade holders.
In order to cut, and avoid uncontrollable lifting of the work
NOTE
piece, the teeth of the blade used on the scroll saw should
always point downward as shown in (Figure 8) when installed.
5. To properly secure the blade securely tighten the wing knob on the
upper and lower holders.
6. Tension blade (see BLADE TENSION below).
◆
Move quick release tension lever to "down" position to tighten the
blade,. As the lever is lowered, tension will be applied to the blade
(Figure 11).
Moving the lever downward should require moderate,
ATTENTION
steady pressure only.
INCREASING THE TENSION: If heavy pressure is needed, the
blade is too tight. Loosen tension by rotating the quick release ten-
