grounded in accordance with all codes and ordinances. Never remove the
grounding prong or modify the plug in any way. Do not use any adapter
plugs. Check with a qualified electrician if you are in doubt as to whether
the outlet is properly grounded. If the tools should electrically malfunction or
break down, grounding provides a low resistance path to carry electricity away
from the user.
5.
6.
Double insulated tools are equipped with a polarized plug (one blade is
wider than the other). This plug will fit in a polarized outlet only one way. If
the plug does not fit fully in the outlet, reverse the plug. If it still does not
fit, contact a qualified electrician to install a polarized outlet. Do not
change the plug in any way. Double insulation
eliminates the need for the
three wire grounded power cord and grounded power supply system.
Avoid body contact with grounded surfaces such as pipes, radiators,
ranges, and refrigerators. There is an increased risk of electric shock if your
body is grounded.
7.
8.
Do not expose power tools to rain or wet conditions. Water entering a power
tool will increase the risk of electric shock.
Do not abuse the Power Cord. Never use the Power Cord to carry the tools
or pull the Plug from an outlet. Keep the Power Cord away from heat, oil,
sharp edges, or moving parts. Replace damaged Power Cords immediately.
Damaged Power Cords increase the risk of electric shock.
9.
When operating a power tool outside, use an outdoor extension cord
marked “W-A” or “W”. These extension cords are rated for outdoor use, and
reduce the risk of electric shock.

GROUNDING
WARNING!
Improperly connecting the grounding wire can result in the risk of electric shock. Check
with a qualified electrician if you are in doubt as to whether the outlet is properly grounded.
Do not modify the power cord plug provided with the tool. Never remove the grounding
prong from the plug. Do not use the tool if the power cord or plug is damaged. If damaged,
have it repaired by service facility before use. If the plug will not fit the outlet, have a proper
outlet installed by a qualified electrician.
GROUNDED TOOLS: TOOLS WITH THREE PRONG PLUGS
1.
Tools marked with “Grounding Required” have a three wire cord and three prong
grounding plug. The plug must be connected to a properly grounded outlet. If
the tool should electrically malfunction or break down, grounding provides a low
resistance path to carry electricity away from the user, reducing the risk of electric
shock. (See Figure A.)
2.
3.
The grounding prong in the plug is connected through the green wire inside the
cord to the grounding system in the tool. The green wire in the cord must be the
only wire connected to the tool’s grounding system and must never be attached
to an electrically “live” terminal. (See Figure A.)
Your tool must be plugged into an appropriate outlet, properly installed and
grounded in accordance with all codes and ordinances. The plug and outlet
should look like those in the following illustration. (See Figure A.)

DOUBLE INSULATED TOOLS: TOOLS WITH TWO PRONG PLUGS
4.
5.
Tools marked “Double Insulated” do not require grounding. They have a special
double insulation system which satisfies OSHA requirements and complies with
the applicable standards of Underwriters Laboratories, Inc., the Canadian
Standard Association, and the National Electrical Code. (See Figure B.)
Double insulated tools may be used in either of the 120 volt outlets shown in the
following illustration. (See Figure B.)

EXTENSION CORDS
1.
2.
Grounded tools require a three wire extension cord. Double Insulated tools
can use either a two or three wire extension cord.
As the distance from the supply outlet increases, you must use a heavier gauge
extension cord. Using extension cords with inadequately sized wire causes a
serious drop in voltage, resulting in loss of power and possible tool damage.
(See Figure C, next page.)
3.
4.
The smaller the gauge number of the wire, the greater the capacity of the cord.
For example, a 14 gauge cord can carry a higher current than a 16 gauge cord.
(See Figure C.)
When using more than one extension cord to make up the total length, make
sure each cord contains at least the minimum wire size required.
(See Figure C.)
5.
If you are using one extension cord for more than one tool, add the nameplate
amperes and use the sum to determine the required minimum cord size.
(See Figure C.)

7.
If you are using an extension cord outdoors, make sure it is marked with the
suffix “W-A” (“W” in Canada) to indicate it is acceptable for outdoor use.
Make sure your extension cord is properly wired and in good electrical condition.
Always replace a damaged extension cord or have it repaired by a qualified
electrician before using it.
8.
Protect your extension cords from sharp objects, excessive heat, and damp or
wet areas.

To replace the Motor Carbon Brushes: It may become necessary at sometime
to replace or clean the two Carbon Brushes (36) when the Motor performance
decreases, or stops working completely. The Carbon Brushes are located on
each side of the Motor Housing (33). To replace the Carbon Brushes, remove
the two Brush Holder Covers (37). Then, remove the two Carbon Brushes from
the two Brush Holders (35). If either Carbon Brush is worn down more than
halfway, replace both Carbon Brushes. If the Carbon Brushes are just dirty,
however, they may be cleaned by rubbing them with a pencil eraser. When
reusing Carbon Brushes, reinstall the brushes in the same orientation as
previously to prevent excess wear. When installing the Carbon Brushes, make
sure the carbon portion of the Carbon Brushes contact the Motor’s Rotor (27) and
that the springs face away from the Motor. Also, make sure the springs operate
freely. After replacement or cleaning, replace the two Brush Holder Covers.
NOTE: New Carbon Brushes tend to arc or spark when first used until they wear
and conform to the Motor’s Rotor. (See Figure I.)
