must be ANSI-approved and breath-
ing protection must be NIOSH-ap-
proved for the specific hazards in the
work area.
c.Do not expose tools to rain or wet
conditions. Water entering a tool
will increase the risk of electric shock.
4. Tool use and care
d.Do not abuse the cord. Never use
the cord for carrying, pulling or
unplugging the tool. Keep cord
away from heat, oil, sharp edges or
moving parts. Damaged or entan-
gled cords increase the risk of electric
shock.
a.Do not force the tool. use the
correct tool for your application.
The correct tool will do the job better
and safer at the rate for which it was
designed.
b.Disconnect the plug from the pow-
er source and allow to cool before
making any adjustments, changing
accessories, or storing this tool.
Such preventive safety measures
reduce the risk of damage or injury.
e.If operating a tool in a damp loca-
tion is unavoidable, use a Ground
Fault Circuit Interrupter (GFCI)
protected supply. Use of a GFCI
reduces the risk of electric shock.
c.Store idle tools out of the reach of
children and do not allow persons
unfamiliar with this tool or these
instructions to operate the tool.
Tools are dangerous in the hands of
untrained users.
3. Personal safety
a.Stay alert, watch what you are do-
ing and use common sense when
operating a tool. Do not use a
tool while you are tired or under
the influence of drugs, alcohol or
medication. A moment of inattention
while operating tools may result in
serious personal injury.
d.Maintain tools. Check for mis-
alignment or breakage of parts and
any other condition that may affect
the tool’s operation. If damaged,
have the tool repaired before use.
Many accidents are caused by poorly
maintained tools.
b.use personal protective equip-
ment. Always wear eye protection.
Safety equipment such as fresh air
mask, non-skid safety shoes, hard
hat, or hearing protection used for
appropriate conditions will reduce
personal injuries.
5. Service
a.Have your tool serviced by a quali-
fied repair person using only iden-
tical replacement parts. This will
ensure that the safety of the tool is
maintained.
c.Do not overreach. Keep proper
footing and balance at all times.
This enables better control of the tool
in unexpected situations.
Safety Warnings
d.Only use safety equipment that
has been approved by an appropri-
ate standards agency. Unapproved
safety equipment may not provide
adequate protection. Eye protection

5. When using a handheld tool, maintain
a firm, controlling grip on the tool.
6. Do not leave the tool unattended
when it is plugged into an electrical
outlet. Unplug the tool from its elec-
trical outlet and allow to cool down
before leaving.
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 a qualified
service technician before use.
If the plug will not fit the
outlet, have a proper outlet
installed by a qualified

of reach of children.
8. Any power cord must be properly
grounded. Ground Fault Circuit Inter-
rupter (GFCI) should also be imple-
mented – it prevents sustained elec-
trical shock.

10. The warnings, precautions, and in-
structions discussed in this instruction
manual cannot cover all possible con-
ditions and situations that may occur.
It must be understood by the operator
that common sense and caution are
factors which cannot be built into this
product, but must be supplied by the
operator.
1. Tools marked with “Grounding Re-
quired” 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 3-Prong Plug
and Outlet.)
4. When using more than one exten-
sion cord to make up the total length,
make sure each cord contains at
least the minimum wire size required.
(See Table A.)
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 Table A.)
2. The grounding prong in the plug is
connected through the green wire in-
side 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 3-Prong Plug
and Outlet.)
6. 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.
7. Make sure the extension cord is prop-
erly wired and in good electrical con-
dition. Always replace a damaged
extension cord or have it repaired by
a qualified electrician before using it.
3. The 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
preceding illustration. (See 3-Prong
Plug and Outlet.)
8. Protect the extension cords from
sharp objects, excessive heat, and
damp or wet areas.
Extension Cords
RECOMMENDED MINIMuM WIRE
1. Grounded tools require a three wire
extension cord. Double Insulated
tools can use either a two or three
wire extension cord.

2. As the distance from the supply outlet
increases, you must use a heavier
gauge extension cord. Using exten-
sion cords with inadequately sized
wire causes a serious drop in voltage,
resulting in loss of power and pos-
sible tool damage.

3. 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 Table A.)
