6. Slowly rotate entire motor by hand to adjust
oscillation. Clockwise rotation will make blade
movement more aggressive on downstroke.
Counterclockwise will
aggressive on upstroke. See Figure 23.
TIP: If more rotation is needed, turn off saw and
install motor mount screws in second set of
holes behind motor flange.
7. When desired oscillation is achieved, securely
tighten motor mount screws (M).

9.8 Arm lift retention

Refer to Figure 24.
If arm will not remain in position after being raised,
loosen hex nut (14mm wrench) and slightly turn
adjustment screw clockwise
screwdriver, until arm remains in raised position. Do
not overtighten. Tighten hex nut.

9.9 Blower nozzle

Adjust blower nozzle away from operator, and as
close to blade as needed without interfering with
blade or workpiece movement.

10.0 Operations

10.1 General operating tips

1. Always use a clean, sharp blade.
2. Maintain proper posture to avoid strain. Saw
table should be set approximately level with
operator's elbows.
3. Avoid wrist or finger strain which can occur by
constantly pushing workpiece against table.
Always use hold-down whenever possible.
4. Guide the wood into the blade slowly to prevent
blade breakage.
5. You will achieve best results when cutting wood
less than 1-inch thick. When cutting stock
thicker than 1-inch, guide the stock very slowly
into the blade, taking care not to bend or twist
the blade.
6. Blade should have minimum 3 teeth in contact
with workpiece at all times.

7. Make relief cuts as needed to prevent binding
of blade in workpiece.
8. A blade has a tendency to follow the wood
grain. Be prepared to compensate for this to
achieve accurate cuts.
9. Use caution when sawing round pieces, such
as dowels, which tend to roll while cutting.
10. Keep fingers away from cutting path. Avoid
awkward hand positions or getting fingers
wedged between saw arm and workpiece when
cutting small workpieces.
11. For fretwork, drill all needed pilot holes at the
same time before moving to the scroll saw. Drill
pilot holes as close as possible to reference
lines.
12. As a general rule, select the narrowest blades
recommended for intricate curve cutting, and
widest blades for straight cuts or large curve
cuts.
13. Run saw only at high enough speed to
efficiently do the work. Constant running at
maximum speed is not necessary for most
operations, may reduce control of the cutting
process, and may hasten wear on the saw.

10.2 On/off controls

With foot pedal: Push on/off switch to ON position
(I). Press foot pedal to operate saw, release pedal
to stop.
Without foot pedal: Push on/off switch to ON
position (I); saw will operate. Press switch to OFF
position (O) to stop.
If foot pedal is not used and
power outage occurs during operation, blade
will resume motion when power is restored.
Turn off switch immediately after power outage
to avoid accidental restart.

10.3 Procedure

1. Install blade appropriate for desired operation.
Make sure blade is properly tensioned, and
teeth point forward and down toward table.
2. Position blower nozzle and hold-down.
For straight cutting or outside curve cutting:
3. Turn on saw and allow blade to reach full
operating speed.
4. Set speed using variable control knob.
5. Hold workpiece firmly against table and feed
workpiece directly into front edge of blade with
steady pressure. See Figures 25 and 26. Do not
use excessive pressure – allow the blade to do
the work. Compensate for blade drift.
