TABLE A
USE PROPER EXTENSION CORD. 7.
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 wear 8.
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.
ALWAYS USE SAFETY GLASSES. Also 9.
use face or dust mask if cutting operation
is dusty. Everyday eyeglasses only have
impact resistant lenses, they are NOT
safety glasses.
MAINTAIN TOOLS WITH CARE. Keep 10.
tools sharp and clean for best and safest
performance. Follow instructions for
lubricating and changing accessories.
DISCONNECT TOOLS before servicing; 11.
when changing accessories, such as
blades, bits, cutters, and the like.
REDUCE THE RISK OF 12.
UNINTENTIONAL STARTING. Make
sure switch is in off position before
plugging in.
USE RECOMMENDED ACCESSORIES. 13.
Consult the owner’s manual for
recommended accessories. The use of
improper accessories may cause risk of
injury to persons.
CHECK DAMAGED PARTS. Before 14.
further use of the tool, a guard or other
part that is damaged should be carefully
checked to determine that it will operate
properly and perform its intended
function – check for alignment of moving
parts, binding of moving parts, breakage
of parts, mounting, and any other
conditions that may affect its operation.
A guard or other part that is damaged
should be properly repaired or replaced.
