Selecting The Correct Speed; Scroll Saw Operation; Oiling The Arm Bearings - 909 LS1620 Instruction Manual

3. Determine the optimum speed by making a trial cut in a
scrap piece of material.
Note. Using the correct speed for the job increases the life
of the saw blade.

Selecting the correct speed

The below table shows the suggested blade and speed to
be used for different materials and applications.

Scroll saw operation

1. Ensure that the table insert is in place and flush with
the table.
2. Start saw.
3. Adjust the speed to suit the workpiece being cut.
4. To begin the cut guide the wood into the moving saw
blade, the blade teeth cut only on the down stroke.
5. The saw will not cut wood by itself, you allow the saw to
cut wood by guiding the wood into the blade as it moves.
6. The drop foot (5) should always be lowered until it just
rests on top of the workpiece to prevent your workpiece
from lifting during operation but not so much that the
workpiece drags. To lower or raise the drop foot loosen
the drop foot locking knob (6) and position the drop foot
so it rests on top of the work piece. Retighten the drop
foot locking knob.
7. Ensure that you feed the wood into the blade slowly
because the teeth of the blade are very small and
they can only remove wood when they are on the
down stroke.
Blade Teeth
Width
per Inch
6 - 10 2.8mm
10 - 15 2.8mm
15 - 18 2.4mm
Strokes
Thickness
per Minute
0.5mm 1200–1600
0.5mm 600–1200
0.3mm 550–600
8. The blade will flex backwards when applying feed
pressure. Too much feed pressure will cause blade
breakage.
9. Best results are achieved when cutting wood less than
25 mm thick.
10. When cutting wood thicker than 25 mm, the user must
feed the wood into the blade very slowly, increase blade
tension and take extra care not to bend or twist the
blade while cutting in order to maximise blade life.
11. Teeth on scroll saw blades wear quickly and as a result
must be replaced frequently for best cutting results.
Scroll saw blades generally stay sharp for 30 minutes
to 2 hours of cutting.
12. Once finished, turn off the saw and unplug the tool from
the power point to prevent unauthorised use.

Oiling the arm bearings

The saws arm bearings should be lubricated after every
50 hours of use. Ensure plug is removed from the mains
power supply.
1. Turn the saw on its side.
2. Squirt a generous amount of
SAE 20 oil around the shaft
end and bronze bearings.
3. Let the oil soak in overnight in
this position.
4. Next day repeat the above
procedure for the opposite
side of the saw.
