TABLE A
USE PROPER EXTENSION CORD.9. 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. Table A shows
the correct size to use depending on
cord length and nameplate ampere
rating. If in doubt, use the next heavier
gauge. The smaller the gauge number,
the heavier the cord.
WEAR PROPER APPAREL. Do not wear10. loose clothing, gloves, neckties, rings,
bracelets, or other jewelry which may get
caught in moving parts. Nonslip footwear
is recommended. Wear protective hair
covering to contain long hair.

is dusty. Everyday eyeglasses only have
impact resistant lenses, they are NOT
safety glasses.
SECURE WORK. Use clamps or a vise12. to hold work when practical. It’s safer
than using your hand and it frees both
hands to operate tool.
DON’T OVERREACH. Keep proper
13. footing and balance at all times.
MAINTAIN TOOLS WITH CARE. Keep
14. tools sharp and clean for best and safest
performance. Follow instructions for
lubricating and changing accessories.
