General Safety Information
WARNING! Read and understand all instructions. Failure
to follow all instructions listed below may
result in electric shock, fire, and/or serious
personal injury.
SAVE THESE INSTRUCTIONS!

Work Area Safety

• Keep your work area clean and well lit. Cluttered
benches and dark areas invite accidents.
• Do not operate tools in explosive atmospheres,
such as in the presence of flammable liquids,
gases, or dust. Tools create sparks which may ignite
the dust or fumes.
• Keep bystanders, children, and visitors away while
operating a tool. Distractions can cause you to lose
control.

Electrical Safety

• 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 qual-
ified electrician if you are in doubt as to whether
the outlet is properly grounded. If the tool should
electrically malfunction or break down, grounding pro-
vides a low resistance path to carry electricity away
from the user.
Grounding prong
• Avoid body contact with grounded surfaces such
as pipes, radiators, ranges and refrigerators. There
is an increased risk of electrical shock if your body is
grounded.
• Don't expose electrical tools to rain or wet condi-
tions. Water entering a tool will increase the risk of
electrical shock.
• Do not abuse cord. Never use the cord to carry the
tools or pull the plug from an outlet. Keep cord
away from heat, oil, sharp edges or moving parts.
Replace damaged cords immediately. Damaged
cords increase the risk of electrical shock.

• When operating a tool outside, use an outdoor
extension cord marked "W-A" or "W". These cords
are rated for outdoor use and reduce the risk of elec-
trical shock.
• Use only three-wire extension cords which have
three-prong grounding plugs and three-pole re-
ceptacles which accept the tool's plug. Use of other
extension cords will not ground the tool and increase
the risk of electrical shock.
• Use proper extension cords. (See chart.) Insufficient
conductor size will cause excessive voltage drop and
loss of power.

• Before using, test the Ground Fault Circuit Inter-
rupter (GFCI) provided with the power cord to in-
sure it is operating correctly. GFCI reduces the
risk of electrical shock.
• Extension cords are not recommended unless
they are plugged into a Ground Fault Circuit In-
terrupter (GFCI) found in circuit boxes or outlet
receptacles. The GFCI on the machine power cord will
not prevent electrical shock from the extension cords.
• Keep all electrical connections dry and off the
ground. Do not touch plugs or tool with wet hands.
Reduces the risk of electrical shock.

Personal Safety

• Stay alert, watch what you are doing and use com-
mon sense when operating a power tool. Do not
use tool while tired or under the influence of drugs,
alcohol, or medications. A moment of inattention
while operating power tools may result in serious per-
sonal injury.
• Dress properly. Do not wear loose clothing or jew-
elry. 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.
• Avoid accidental starting. Be sure switch is OFF
before plugging in. Carrying tools with your finger on
the switch or plugging tools in that have the switch ON
invites accidents.
• Remove adjusting keys or switches before turning
