Extension cord safety
WARNING: Keep the extension cord clear of the working area. Position the cord
so it will not get caught on the workpiece, tools or any other obstructions while you are working with the
power tool.
Make sure any extension cord used with this tool is in good condition. When using an extension cord, be
sure to use one of heavy enough gauge to carry the current the tool will draw. An undersized cord will
cause a drop in line voltage resulting in loss of power and overheating.
The table below shows the correct size to use according to cord length and nameplate ampere rating. If
in doubt, use the next heavier gauge. The smaller the gauge number the heavier the cord.
Be sure your extension cord is properly wired and in good condition. Always replace a damaged exten-
sion cord or have it repaired by a qualied electrician before using it. Protect your extension cord from
sharp objects, excessive heat and damp or wet areas.
Use a separate electrical circuit for your power tools. This circuit must not be less than 14 gauge wire
and should be protected with either a 15 A time delayed fuse or circuit breaker. Before connecting the
power tool to the power source, make sure the switch is in the OFF position and the power source is the
same as indicated on the nameplate. Running at lower voltage will damage the motor.
