tions of this tool DO NOT modify this Bench Grinder in
any way°
BEFORE USING THE BENCH GRINDER
To avoid serious injury and damage to the tool, read
and follow all of the Safety and Operating instructions
before operating the Bench Grinder..
1.. Some dust created by using power tools contains
chemicals known to the State of California to cause
cancer, birth defects, or other reproductive harm.
Some examples of these chemicals are:
o Lead from lead-based paints.
• Crystalline silica from bricks, cement, and other
masonry products.
o Arsenic and chromium from chemically treated
lumber..
Your risk from these exposures varies, depending
on how often you do this type of work_ To reduce
your exposure to these chemicals: work in a well-
ventilated area, and work with approved safety
equipment, such as those dust masks that are
specially designed to filter out microscopic particles°
2.. READ the entire Owner's Manual.. LEARN how to
use the tool for its intended applications.
3,. GROUND ALL TOOLS. If the toot is supplied with
a 3-prong plug, it must be plugged into a 3-contact
electrical receptacle,. The 3rd prong is used to
ground the tool and provide protection against acci-
dental electric shock.. DO NOT remove the 3rd
prong.. See Grounding Instructions on page 4.
4., AVOID A DANGEROUS WORKING ENVIRON-
MENT. DO NOT use electrical tools in a damp
environment or expose them to rain..
5. DO NOT use electrical tools in the presence of
flammable liquids or gases..
6, ALWAYS keep the work area clean, welt lit, and
organized.. DO NOT work in an environment with
floor surfaces that are slippery from debris, grease,
and wax..
7_ KEEP VISITORS AND CHILDREN AWAY. DO NOT
permit people to be in the immediate work area,
especially when the electrical tool is operating_
DO NOT FORCE THE TOOL to perform an opera-
tion for which it was not designed. Itwill do a safer
and higher quality job by only performing operations
for which the tool was intended.
9_
WEAR PROPER CLOTHING. DO NOT wear loose
clothing, gloves, neckties, or jewelry', These items
can get caught in the machine during operations
and pul! the operator into the moving parts,. The
user must wear a protective cover on their hair, if
the hair is long, to prevent itfrom contacting any
moving parts°
10.
ALWAYS WEAR EYE PROTECTION, Any power
tool can throw debris intothe eyes during opera-
tions, which could cause severe and permanent
eye damager ALWAYS wear Safety Goggfes (that
complywith ANSI standard Z87..1) when operating
power tools,.Safety Goggles are available at Sears

26 USE A PROPER EXTENSION CORD IN GOOD
CONDITION. When using an extension cord, be
sure to use one hearty enough to carry the current
your product will draw. The table at right shows the
correct size to use depending on cord length and
nameplate amperage rating_ If in doubt, use the
next heavier gauge The smaller the gauge number,
the larger diameter of the extension cord. If in doubt
of the proper size of an extension cord, use a short-
er and thicker cord, An undersized cord will cause
and overheating USE ONLY A 3-WIRE EXTENo
SlON CORD THAT HAS A 3-PRONG GROUND-
ING PLUG AND A 3-POLE RECEPTACLE THAT
ACCEPTS THE TOOUS PLUG.
GUIDELINES FOR
EXTENSION CORDS
If you are using an extension cord outdoors, be sure
it is marked with the suffix "W-A" ('_V'_in Canada) 1o
indicate that it is acceptable for outdoor user
Be sure your extension cord is properly sized, and

IN THE EVENT OF A MALFUNCTION OR BREAK-
DOWN, groundingprovidesthe path of least resistance
for electric current and reduces the riskof electric
shock. This tool is equipped with an electric cord that
has an equipment groundingconductor and a ground-
ing plug.The plug MUST be plugged into a matching
electrical receptacle that is properlyinstalled and
grounded in accordance with ALL local codes and ordi-
nances°
DO NOT MODIFY THE PLUG PROVIDED. If it will not
fit the electrical receptacle, have the proper electrical
receptacle installed by a qualified electrician
IMPROPER ELECTRICAL CONNECTION of the equip-
ment grounding conductor can result in risk of electric
shock. The conductor with the green insulation (with or
without yellow stripes) isthe equipment grounding con-
ductor. DO NOT connect the equipment grounding con-
ductor to a live terminal if repair or replacement of the
electric cord or plug is necessary_
CHECK with a qualified electrician or service personnel
ifyou do not completely understand the grounding
instnJctions, or if you are not sure the tool is properly
grounded.
USE ONLY A 3-WIRE EXTENSION CORD THAT HAS
A 3-PRONG GROUNDING PLUG AND A 3-POLE
RECEPTACLE THAT ACCEPTS THE TOOL'S PLUG.
REPLACE A DAMAGED OR WORN CORD IMMEDI-
ATELY.
