use one heavy enough to carry the current your product
will draw. The table on the following page shows the cor-
rect size to use depending on cord length and nameplate
amperage rating. If in doubt, use the next heavier gauge.
The smaller the gauge number, the larger diameter of the
extension cord. If in doubt of the proper size of an exten-
sion cord, use a shorter and thicker cord. An undersized
cord will cause a drop in line voltage resulting in a loss of
power and overheating.
USE ONLY A 3-WIRE EXTENSION CORD THAT HAS
A 3-PRONG GROUNDING PLUG AND A 3-POLE
RECEPTACLE THAT ACCEPTS THE TOOL’S PLUG.

SAFETY INSTRUCTIONS
THE USE OF AN EXTENSION CORD
WITH THIS MACHINE IS NOT RECOMMENDED. For
best power and safety, plug the machine directly into a
dedicated, grounded electrical outlet that is within the
supplied cord length of the machine.
If an extension cord needs to be used, it should only be
for a limited operation of the machine. The extension
cord should be as short as possible in length, and have
a minimum gauge size of 14AWG.
Check extension cords before each
use. If damaged replace immediately. Never use a tool
with a damaged cord, since touching the damaged
area could cause electrical shock, resulting in serious
injury.
Use a proper extension cord. Only use cords listed by
Underwriters Laboratories (UL). Other extension cords can
cause a drop in line voltage, resulting in a loss of power
and overheating of tool. When operating a power tool out-
doors, use an outdoor extension cord marked “W-A” or “W”.
These cords are rated for outdoor use and reduce the risk
of electric shock.
DO NOT MODIFY ANY PLUG. If it will not t the electrical
receptacle, have the proper electrical receptacle installed
by a qualied electrician.
IMPROPER ELECTRICAL CONNECTION of the
equipment grounding conductor can result in risk of
electric shock. The conductor with the green insulation
(with or without yellow stripes) is the equipment ground-
ing conductor. DO NOT connect the equipment grounding
conductor to a live terminal if repair or replacement
of the electric cord or plug is necessary.
CHECK with a qualied electrician or service personnel if
you do not completely understand the grounding
instructions, or if you are not sure the tool is properly
grounded when installing or replacing a plug.
USE ONLY A 3-WIRE EXTENSION CORD THAT HAS
THE PROPER TYPE OF A 3-PRONG GROUNDING PLUG
THAT MATCHES THE MACHINE’S 3-PRONG PLUG AND
ALSO THE 3-POLE RECEPTACLE THAT ACCEPTS THE
TOOL’S PLUG. *
REPLACE A DAMAGED OR WORN CORD IMMEDIATELY.
This tool is intended for use on a circuit that has an
electrical receptacle as shown in FIGURE A. It shows a
3-wire electrical plug and electrical receptacle that has a
grounding conductor. If a properly grounded electrical
receptacle is not available, an adapter as shown in
FIGURE B can be used to temporarily connect this plug to
a 2-contact ungrounded receptacle. The adapter has a rigid
lug extending from it that MUST be connected to a perma-
nent earth ground, such as a properly grounded receptacle
box. THIS ADAPTER IS PROHIBITED IN CANADA.
FIGURE C shows the type of the 220V, 3-wire electrical
plug and receptacle that has a grounding conductor that is
required if the motor wiring is changed.
IN THE EVENT OF A MALFUNCTION OR BREAKDOWN,
grounding provides the path of least resistance for electric
current and reduces the risk of electric shock. This tool
is equipped with an electric cord that has an equipment
grounding conductor and requires a grounding plug (not
included). The plug MUST be plugged into a matching elec-
trical receptacle that is properly installed and grounded in
accordance with ALL local codes and ordinances.
THIS TOOL MUST BE GROUNDED
WHILE IN USE TO PROTECT THE OPERATOR FROM
ELECTRIC SHOCK.
EXTENSION CORDS
Keep the extension cord clear of
the working area. Position the cord so that it will not
get caught on lumber, tools or other obstructions while
you are working with your power tool.
* Canadian electrical codes require extension cords
to be certied SJT type or better.
** The use of an adapter in Canada is not acceptable.
