ASSEMBLY
Required tools for assembly:
1. Combination square
2. Phillips screwdriver
3. Slotted screwdriver
Attach the plastic tubing to the sawdust blower and tube
on the top of the saw housing.
Apply a coat of paste wax to the saw table surface to allow
the workpiece to slide easily across the surface. Wipe the saw
table thoroughly with a dry cloth to remove excess wax.
Mounting Scroll Saw to Workbench
Warning! To avoid serious personal injury from
unexpected tool movement, always securely mount scroll
saw to a workbench.
If the scroll saw is to be used in a permanent application,
we recommend that you secure it in a permanent location
such as a workbench. When mounting the saw to a workbench,
holes should be drilled through the supporting surface
of the workbench.
► Each hole in the base of the saw should be bolted securely
using machine bolts, washers, and nuts (not included).
Bolts should be of sufficient length to accommodate
the saw base, washers, nuts, and the thickness
of the workbench.
► Place scroll saw on workbench. Using the saw base as
a pattern, locate and mark the holes where the scroll saw
is to be mounted.
► Drill four holes through the workbench.
► Place scroll saw on workbench aligning holes in the saw
base with the holes drilled in the workbench.
► Insert all four bolts (not included) and tighten securely with
washers and nuts (not included).
Note: All bolts should be inserted from the top. Install
the washers and nuts from the underside of the bench.
Supporting surface where scroll saw is mounted should
be examined carefully after mounting to insure that no
movement during use can result. If any tipping or walking
is noted, secure workbench or supporting surface before
beginning cutting operations.
Clamping Scroll Saw to Workbench (Fig. B)
If the scroll saw is to be used in a portable application,
it is recommended that you fasten it permanently to
a mounting board that can easily be clamped to a workbench
or other supporting surface. The mounting board should be
of sufficient size to avoid tipping of saw while in use. Any good
grade plywood or chipboard with a 3/4 in. (19mm) thickness
is recommended.
► Mount saw to board using holes in saw base as a template
for hole pattern. Locate and mark the holes where scroll
saw is to be mounted.
► Follow last three steps in previous section called
"Mounting Scroll Saw to Workbench".
If lag bolts are being used, make sure they are long
enough to go through holes in the saw base and
the material the saw is being mounted to.
If machine bolts are being used, make sure they are long
enough to go through holes in the saw base, the material
the saw is being mounted to, and the washers and nuts.
Note: It may be necessary to countersink washers and nuts
on the bottom side of mounting board.
ADJUSTMENTS
Warning! To prevent accidental starting that could cause
possible serious personal injury, turn off the saw and unplug
the saw from the power source before making any adjustments.
Drop Foot (Fig. C)
To prevent workpiece from lifting, the drop foot should be
adjusted so it just rests on the top of the workpiece. The drop
foot should not be adjusted so that the workpiece drags.
Always retighten the drop foot lock knob after each adjustment
has been made.
► Loosen the drop foot lock knob.
► Lower or raise the drop foot to the desired position.
► Retighten the drop foot lock knob.
The tall, front part of the drop foot acts as a blade guard
to prevent accidental contact with the blade.
Sawdust Blower (Fig. C)
Warning! Failure to turn the saw off, remove the switch
key, and unplug the saw from the power source could result in
accidental starting causing possible serious injury.
The sawdust blower is designed and preset to direct air
to the most effective point on the cutting line. Be sure drop
foot is properly adjusted to secure workpiece and direct air
to the cutting surface.
► Plastic tubing should be connected to the bellows tube
before starting the saw.

Warning! Failure to turn the saw off, remove the switch
key, and unplug the saw from the power source could result
