SPECIFIC SAFETY RULES
Hold tool by insulated gripping surfaces when performing an operation where the cutting tool may contact
hidden wiring or its cord.
Contact with a “live” wire will make exposed metal parts of the tool “live” and shock the operator.
ADDITIONAL SAFETY RULES
■
Know your power tool. Read operator’s manual
carefully. Learn its applications and limitations,
as well as the specific potential hazards related
to this tool.
Following this rule will reduce the risk
of electric shock, fire, or serious injury.
■
Always wear safety glasses. Everyday eye-
glasses have only impact-resistant lenses; they
are NOT safety glasses.
Following this rule will re-
duce the risk of serious personal injury.
■
Protect your lungs. Wear a face or dust mask if
the operation is dusty.
Following this rule will re-
duce the risk of serious personal injury.
■
Protect your hearing. Wear hearing protection
during extended periods of operation.
Following
this rule will reduce the risk of serious personal in-
jury.
■
Inspect tool cords periodically and, if damaged,
have repaired at your nearest authorized service
center. Constantly stay aware of cord location.
Following this rule will reduce the risk of electric
shock or fire.
■
Check damaged parts. Before further use of the
tool, a guard or other part that is damaged should
be carefully checked to determine that it will
operate properly and perform its intended func-
tion. Check for alignment of moving parts, bind-
ing of moving parts, breakage of parts, mount-
ing, and any other conditions that may affect its
operation. A guard or other part that is damaged
should be properly repaired or replaced by an
authorized service center.
Following this rule will
reduce the risk of shock, fire, or serious injury.
■
Do not abuse cord. Never carry the tool by the
cord or yank it to disconnect it from the recep-
tacle. Keep cord away from heat, oil, and sharp
edges.
Following this rule will reduce the risk of elec-
tric shock or fire.
■
Make sure your extension cord is in good condi-
tion. When using an extension cord, be sure to
use one heavy enough to carry the current your
product will draw. A wire gage size (A.W.G.) of at
least 16 is recommended for an extension cord
100 feet or less in length. A cord exceeding 100
feet is not recommended. If in doubt, use the next
heavier gage. The smaller the gage number, the
heavier the cord.
An undersized cord will cause a
drop in line voltage resulting in loss of power and
overheating.
■
Inspect for and remove all nails from lumber be-
fore using this tool.
Following this rule will reduce
the risk of serious personal injury.
■
Drugs, alcohol, medication. Do not operate tool
while under the influence of drugs, alcohol, or
any medication.
Following this rule will reduce the
risk of electric shock, fire, or serious personal injury.
■
Save these instructions. Refer to them frequently
and use them to instruct others who may use
this tool. If you loan someone this tool, loan them
these instructions also.
WARNING:
Some dust created by power sanding, sawing,
grinding, drilling, and other construction activities
contains chemicals known to cause cancer, birth
defects or other reproductive harm. Some examples
of these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement
and other masonry products, and
• arsenic and chromium from chemically-
treated lumber.
Your risk from these exposures varies, depending
on how often you do this type of work. To reduce
your exposure to these chemicals: work in a well
ventilated area, and work with approved safety
equipment, such as those dust masks that are
specially designed to filter out microscopic particles.

fied repair personnel.

formed by unqualified personnel could result in a risk
of injury.
■
When servicing a tool, use only identical replace-
ment parts. Follow instructions in the Mainte-
nance section of this manual.
