increase the risk of electric shock.  
d. When operating a power tool  
outdoors, use an extension cord  
suitable for outdoor use. Use  
of a cord suitable for outdoor use  
reduces the risk of electric shock.  
f. Only use safety equipment that has  
been approved by an appropriate  
standards agency. Unapproved  
safety equipment may not provide  
adequate protection. Eye protection  
must be ANSI-approved and breathing  
protection must be NIOSH-approved for  
the specific hazards in the work area.  
e. If operating a power tool in a damp  
location is unavoidable, use a  
Ground Fault Circuit Interrupter  
(GFCI) protected supply. Use of a  
GFCI reduces the risk of electric shock.  
4. Power tool use and care  
3. Personal safety  
a. Do not force the power tool. Use  
the correct power tool for your  
application. The correct power tool  
will do the job better and safer at  
the rate for which it was designed.  
a. Stay alert, watch what you are  
doing and use common sense when  
operating a power tool. Do not use  
a power tool while you are tired  
or under the influence of drugs,  
alcohol or medication. A moment of  
inattention while operating power tools  
may result in serious personal injury.  
b. Do not use the power tool if the  
switch does not turn it on and  
off. Any power tool that cannot  
be controlled with the switch is  
dangerous and must be repaired.

accessories, or storing power  
tools. Such preventive safety  
conditions will reduce personal injuries.  
c. Prevent unintentional starting.  
Ensure the switch is in the off‑  
position before connecting to power  
source and/or battery pack, picking  
up or carrying the tool. Carrying  
power tools with your finger on the  
switch or energizing power tools that  
have the switch on invites accidents.  
measures reduce the risk of starting  
the power tool accidentally.  
d. Store idle power tools out of

be implemented – it prevents  
sustained electrical shock.  
Vibration Safety  
This tool vibrates during use. Repeated  
or long-term exposure to vibration  
may cause temporary or permanent  
physical injury, particularly to the  
hands, arms and shoulders. To reduce  
the risk of vibration-related injury:

GROUNDING  
TO PREVENT  
ELECTRIC SHOCK  
AND DEATH FROM INCORRECT  
GROUNDING WIRE  
Extension Cords  
1. Grounded tools require a three  
wire extension cord. Double  
CONNECTION:  
Insulated tools can use either a  
two or three wire extension cord.  
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 service facility  
2. 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 Table A.)  
before use. If the plug will not fit 3. The smaller the gauge number of  
the outlet, have a proper outlet  
installed by a qualified  
electrician.  
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.)  
Double Insulated Tools: Tools  
with Two Prong Plugs  
4. 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 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.)  
Outlets for 2‑Prong Plug  
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.  
1. 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.  
7. Make sure the 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.  
2. Double insulated tools may be used in  
either of the 120 volt outlets shown in the
