General Safety Rules
WARNING
Read and understand all instructions. Failure to follow all in-
structions listed below may result in electric shock, fire,
and/or serious injury.
SAVE THESE INSTRUCTIONS!
Work Area
• Keep 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 li-
quids, gases, or dust. Power tools create sparks
which may ignite the dust or fumes.
• Keep bystanders, children, and visitors away while
operating a power tool. Distractions can cause you to
lose control.
Electrical Safety
• Grounded tools must be plugged into an outlet
properly installed and grounded in accordance
* The text used in the General Safety Rule section of this manual is verbatim, as required, from the applicable UL/CSA 745 1st edition standard. This section con-
tains general safety practices for many different types of power tools. Not every precaution applies to every tool, and some do not apply to this tool.

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 tool 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 such
as pipes, radiators, ranges and refrigerators. There
is an increased risk of electric shock if your body is
grounded.
• Do not expose power tools to rain or wet condi-
tions. Water entering a power tool will increase the risk
of electric shock.
• Do not abuse the cord. Never use the cord to carry
the tool 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 electric shock.
• When operating a power tool outside, use an out-
door extension cord marked "W-A" or "W". These
