Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy 
enough to carry the current your product 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 be used according to cord length and 
nameplate ampere rating. When in doubt, use a heavier cord. The smaller the gauge number, the heavier the cord. 

Make sure your extension cord is properly wired and in good condition. Always replace a damaged extension cord 
or have it repaired by a qualified person before using it. Protect your extension cords from sharp objects, excessive 
heat and damp/wet areas.

wear. Keep the floor clear of oil, scrap, and other debris. 

17. NEVER LEAVE A RUNNING TOOL UNATTENDED. Turn the power switch to OFF. Do not leave the 
tool until it has come to a complete stop. 

18. NEVER STAND ON A TOOL. Serious injury could result if the tool tips or is accidentally hit. DO NOT store 
anything above or near the tool.

cleaning, or working on the tool.

lower voltage will damage the motor.
