Motor Specifications
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 Scroll Saw is designed to use a Variable Speed RPM motor.
It is wired for operation on 110-120 volts, 60 Hz. alternating cur-
rent. Before connecting the motor cord to power source, make
certain the switch is in the "OFF" position and be sure the elec-
tric current is of the same characteristics as stamped on the
nameplate.
Connection To A Power
Source
This machine must be grounded while in use to protect the oper-
ator from electric shock.
Plug power cord into a 110-120V properly grounded type outlet
protected by a 15-amp dual element time delay fuse or circuit
breaker.
Not all outlets are properly grounded. If you are not sure that
your outlet, as pictured below, is properly grounded; have it
checked by a qualified electrician.
To avoid electric shock, do not touch the

3-PRONG PLUG
This power tool is equipped with a 3-conductor cord and
grounding type plug, approved by Underwriters Laboratories
and the Canadian Standards Association. The ground con-

prong in the attachment plug at the other end.
This plug requires a mating 3-conductor grounded type outlet
as shown. It must be grounded in accordance with all local
codes and ordinances.
If the outlet you are planning to use for this power tool is of the
two-prong type, DO NOT REMOVE OR ALTER THE
GROUNDING PRONG IN ANY MANNER. Have a qualified
electrician replace the TWO-prong outlet with a properly
grounded THREE prong outlet.
Improper connection of the equipment-grounding conductor
can result in a risk of electric shock. If repair or replacement of
the electric cord or plug is necessary, do not connect the
equipment-grounding conductor to a live terminal.
Check with a qualified electrician or service personnel if the
grounding instructions are not completely understood, or if in
doubt as to whether the tool is properly grounded.
The temporary adapter should be used only until a properly
grounded outlet can be installed by a qualified electrician.
The green grounding lug extending from the

ADAPTER
NOTE: The adapter illustrated is for use only if you already
have a properly grounded 2-prong receptacle. Adapter is not
allowed in Canada by the Canadian Electrical Code. Always
use proper extension cord.
The use of any extension cord will cause some loss of power.
To keep this to a minimum and to prevent overheating and
motor burn-out, use the table below to determine the mini-
mum wire size (A.W.G.) extension cord. Use only 3-wire exten-
sion cords which have 3-prong grounding type plugs and 3-
pole receptacles which accept the tool's plug. Make sure your
extension cord is in good condition.
