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 power tools in explosive atmo-
spheres, 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 qualified
electrician if you are in doubt as to whether the out-
let 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.
• Avoid body contact with grounded surfaces. There
is an increased risk of electrical shock if your body is
grounded.
• Do not expose electrical tools to rain or wet con-
ditions. 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 power tool outside, use an out-
door extension cord marked “W-A” or “W”. These
cords are rated for outdoor use and reduce the risk of
electrical 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, loss
of power.
• Keep all electric 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, jew-
elry, 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 before turning the tool
ON. A wrench or a key that is left attached to a rotating
part of the tool may result in personal injury.
• Do not over-reach. Keep proper footing and bal-
ance at all times. Proper footing and balance enables
better control of the tool in unexpected situations.
• Wear hearing protectors, ear plugs or muffs when
using tool. Noise level may affect hearing with pro-
longed use.
• Use safety equipment. Always wear eye protec-
