It is strongly recommended the foot pedal be
secured in place using screws through the two
holes. It may be secured directly to the floor or a
wide board laid beneath the saw.
7.7 Dust collection
A dust collector or shop vacuum can be connected
to the 2-1/2-inch diameter dust port with a hose and
reducing adaptor (not provided). Secure the hose to
the port with hose clamp or cable tie.
A collector with minimum 300 CFM extraction is
recommended.
8.0 Electrical connections
The JWSS-18B Scroll Saw is prewired for 120-volt
power. The saw comes with a plug designed for use
on a circuit with a grounded outlet that looks like the
one pictured in A, Figure 8-1.
Before connecting to power source, be sure switch
is in off position.
It is recommended that the scroll saw be connected
to a dedicated 15 amp circuit with circuit breaker or
fuse. If connected to a circuit protected by fuses, use
time delay fuse marked "D". Local codes take
precedence over recommendations.
8.1 GROUNDING INSTRUCTIONS
This machine must be grounded. In the event of a
malfunction or breakdown, grounding provides a
path of least resistance for electric current to reduce
the risk of electric shock. This tool is equipped with
an electric cord having an equipment-grounding
conductor and a grounding plug. The plug must be
plugged into a matching outlet that is properly
installed and grounded in accordance with all local
codes and ordinances.
Do not modify the plug provided - if it will not fit the
outlet, have the proper outlet installed by a qualified
electrician.
Improper connection of the equipment-grounding
conductor can result in a risk of electric shock. The
conductor with insulation having an outer surface
that is green with or without yellow stripes is the
equipment-grounding
conductor.
replacement of the electric cord or plug is
necessary, do not connect the equipment-grounding
conductor to a live terminal.
Check
electrician or service personnel if the grounding
instructions are not completely understood, or if
in doubt as to whether the tool is properly
grounded. Failure to comply may cause serious
or fatal injury.
Use only 3-wire extension cords that have 3-prong
grounding plugs and 3-pole receptacles that accept
the tool's plug.

This tool is for use on a nominal 120-V circuit, and
has a grounded plug that looks like the plug
illustrated in sketch A in Figure 8-1. A temporary
adaptor that looks like the adaptor illustrated in
sketches B and C may be used to connect this plug
to a 2-pole receptacle as shown in sketch B if a
properly grounded outlet is not available. The
temporary adaptor should be used only until a
properly grounded outlet (sketch A) can be installed
by a qualified electrician. The green colored rigid
ear, lug, or the like extending from the adaptor must
be connected to a permanent ground such as a
properly grounded outlet box cover. Whenever the
adaptor is used, it must be held in place by a metal
screw.
In Canada, the use of a temporary adaptor is not
permitted by the Canadian Electrical Code, C22.1.

8.2 Extension cords
The use of extension cords is discouraged; try to
position machines near the power source. If an
extension cord is necessary, make sure it is in good
condition. When using an extension cord, be sure to
use one heavy enough to carry the current your
product will draw. An undersized cord will cause a
drop in line voltage resulting in loss of power and
overheating. Table 2 shows correct size to use
depending on cord length and nameplate ampere
rating. If in doubt, use the next heavier gauge. The
smaller the gauge number, the heavier the cord.
