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 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. 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.
5. Do not expose power tools to rain or wet conditions. Water entering a power tool
will increase the risk of electric shock.
6. 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.
7. 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.
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 immediately. Damaged Power
Cords increase the risk of electric shock.
