GENERAL SAFETY RULES
WARNING!
READ AND UNDERSTAND ALL INSTRUCTIONS
Failure to follow all instructions listed below may result in
electric shock, fire, and/or serious injury.
SAVE THESE INSTRUCTIONS
WORK AREA
1.
Keep your work area clean and well lit.
Cluttered benches and dark areas
invite accidents.
2.
Do not operate power tools in explosive atmospheres, such as in the
presence of flammable liquids, gases, or dust.
Power tools create sparks
SKU 91110
PAGE 2
which may ignite the dust or fumes.
3.
Keep bystanders, children, and visitors away while operating a power tool.
Distractions can cause you to lose control. Protect others in the work area from
debris such as chips and sparks. Provide barriers or shields as needed.
ELECTRICAL SAFETY
4.
Grounded tools must be plugged into an outlet properly installed and
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.
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.
6.
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.
Do not expose power tools to rain or wet conditions.
Water entering a power
tool will increase the risk of electric shock.
8.
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 immedi-
ately.
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.
PERSONAL SAFETY
10.
Stay alert. Watch what you are doing, and use common sense when oper-
ating a power tool. Do not use a power tool while tired or under the influ-
ence of drugs, alcohol, or medication.
A moment of inattention while operat-
ing power tools may result in serious personal injury.
SKU 91110
PAGE 3
11.
Dress properly. Do not wear loose clothing or jewelry. Contain long hair.
Keep your hair, clothing, and gloves away from moving parts.
Loose
clothes, jewelry, or long hair can be caught in moving parts.
12.
Avoid accidental starting.
Be sure the Power Switch is off before plugging
in.
Carrying power tools with your finger on the Power Switch, or plugging in
power tools with the Power Switch on, invites accidents.
13.
Remove adjusting keys or wrenches before turning the power tool on.
A
wrench or a key that is left attached to a rotating part of the power tool may result
in personal injury.
14.
Do not overreach. Keep proper footing and balance at all times.
Proper
footing and balance enables better control of the power tool in unexpected
situations.
15.
Use safety equipment. Always wear eye protection.
Always wear ANSI
approved safety glasses under a properly shaded welding helmet. Respirator ,
leather work shoes with rubber soles, hard hat or hearing protection must be
used for appropriate conditions.
TOOL USE AND CARE
16.
Use clamps (not included) or other practical ways to secure and support
the workpiece to a stable platform.
Holding the work by hand or against your
body is unstable and may lead to loss of control.
17.
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 is designed.
18.
Do not use the power tool if the Power Switch does not turn it on or off.
Any tool that cannot be controlled with the Power Switch is dangerous and must
be replaced.
19.
Disconnect the Power Cord Plug from the power source before making any
adjustments, changing accessories, or storing the tool.
Such preventive
safety measures reduce the risk of starting the tool accidentally.
20.
Store idle tools out of reach of children and other untrained persons.
Tools
are dangerous in the hands of untrained users.
21.
Maintain tools with care. Keep cutting tools sharp and clean.
Properly
maintained tools with a sharp cutting edge are less likely to bind and are easier
to control. Do not use a damaged tool. Tag damaged tools “Do not use” until
repaired.
SKU 91110
PAGE 4
22.
Check for misalignment or binding of moving parts, breakage of parts, and
any other condition that may affect the tool’s operation. If damaged, have
the tool serviced before using.
Many accidents are caused by poorly main-
tained tools.
23.
Use only accessories that are recommended by the manufacturer for your
model.
Accessories that may be suitable for one tool may become hazardous
when used on another tool.
SERVICE
24.
Tool service must be performed only by qualified repair personnel.
Service
or maintenance performed by unqualified personnel could result in a risk of injury.
25.
When servicing a tool, use only identical replacement parts. Follow
instructions in the “Inspection, Maintenance, And Cleaning” section of this
manual.
Use of unauthorized parts or failure to follow maintenance instructions
may create a risk of electric shock or injury.
GROUNDING
WARNING!
Improperly connecting the grounding wire can result in the risk of electric
shock. Check with a qualfified 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 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 elec-
tric shock.
(See Figure A, next page.)
2. 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.
