POWER SUPPLY
1, Motor Specifications
The A-C motor used in this saw is a capacitor-start,
non-reversible type having the following specifications:
Voltage ............................. 120/240
Amperes .............................. 11/5.5
Hertz (cycles) ............................. 60
Phase ................................ Single
RPM .................................. 3450
Rotation as viewed from saw blade end .... Clockwise
CAUTION: Your saw is wired for 120V operation.
Connect to a 120V, 15-Amp. branch circuit and use a
15-Amp. time-delay fuse or circuit breaker. If the
motor is used for 240V operation, connect to a
15-Amp. branch circuit and use a 15-Amp. time-delay
fuse or circuit breaker.
This machine must be grounded while in use to protect
the operator from electric shock.
IF YOU ARE NOT SURE THAT YOUR OUTLET IS
PROPERLY GROUNDED, HAVE IT CHECKED BY A
QUALIFIED ELECTRICIAN.
WARNING: DO NOT PERMIT FINGERS TO TOUCH
THE TERMINALS OF PLUGS WHEN INSTALLING
OR REMOVING THE PLUG TO OR FROM THE
OUTLET.
WARNING: IF NOT PROPERLY GROUNDED THIS
POWER TOOL CAN INCUR THE POTENTIAL
HAZARD OF ELECTRICAL SHOCK.
PARTICULARLY WHEN USED IN DAMP
LOCATIONS IN PROXIMITY TO PLUMBING. IF AN
ELECTRICAL SHOCK OCCURS THERE IS THE
POTENTIAL OF A SECONDARY HAZARD SUCH AS
YOUR HANDS CONTACTING THE SAWBLADE.
IF POWER CORD IS WORN OR CUT, OR DAMAGED
IN ANY WAY, HAVE IT REPLACED
IMMEDIATELY.
If your unit is for use on less than 150 volts it has a
plug that looks like below.

GROUNDING PRONG
This power tool is equipped with a 3-conductor cord
and grounding type plug which has a grounding prong,
Listed by Underwriters' Laboratories. The ground
conductor has a green jacket and is attached to the tool
1.
housing at one end and to the ground prong in the
attachment plug at the other end.
This plug requires a mating 3-conductor grounded type
outlet as shown.
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. Use an adapter as shown and always connect
the grounding lug to known ground.
It it recommended that you have a qualified electrician
replace the TWO prong outlet with a properly grounded
THREE prong outlet.
An adapter as shown below is available for connecting
plugs to 2-prong receptacles. The green grounding lug
extending from the adapter must be connected to a
permanent ground such as to a properly grounded
outlet box.

ELECTRICAL CONNECTIONS
WARNING: CHANGES IN ELECTRICAL
CONNECTIONS SHOULD BE MADE BY A
QUALI FlED ELECTRICIAN.
Changing Motor Connections
a. Under normal home workshop usage, and if proper
(full) voltage is supplied to the motor, your saw will
operate efficiently on 120V, as connected at the
factory. However, if any of the following conditions
exists, it will be advisable for you to reconnect the
motor for 240V operation - to obtain the
efficiency and performance for which your saw is
designed:
(1} Heavy-duty operations.
(2} Either an undersized or an overloaded branch
circuit serving the saw motor.
(3) Low voltage supplied by the power source,
which the power company cannot correct.
b. Motor wiring connections for 120V (as made at the
factory) are described below. Necessary
reconnections for 240V operation are also described
following. Whenever changing connections from
120V to 240V or vice-versa, make certain that a//
necessary steps (including proper fusing of the
branch circuit) are completed.
