If using an extension cord make sure it is in good condition first. 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 that will result in a loss of power and 

overheating. TABLE 1, Page 10 shows the correct AWG size to use depending on cord 

length and nameplate ampere rating. If in doubt, use the next heavier gage. The smaller 

the gage number, the heavier the cord.

DO NOT

 wear loose clothing, gloves, neckties, rings, bracelets, or other jewelry that may 

be caught in moving parts. Non-slip footwear is recommended.  Wear protective hair 

covering to contain long hair.

Keep proper footing and balance at all times by not overreaching.

Clamps or a vise should be used to hold work whenever practical. Keeping your 

hands free to operate a power tool is safer.

Keep tools clean for the best and safest performance.  Always follow maintenance 

instructions for lubricating, and when changing accessories.

Power tools should always be disconnected before servicing or when changing 

accessories, such as blades, bits, cutters, and the like.

Make the workshops kid proof by using padlocks, master switches or by removing starter 

keys.

A power tool will do a job better and safer operating at the rate for which it was designed.

DO NOT

 force a tool or an attachment, to do a job that it was not designed to do.
