SAFETY RULES FOR
SANDERS AND GRINDERS
1. Always wear safety goggles or other eye protection when
using this tool.
2. When grinding, always keep guard in place.
3. Use only grinding wheels having a maximum operating
speed at least as high as “NO LOAD RPM" marked on the
tool’s nameplate. This precaution also applies to any
accessory on any tool.
4. Before using, inspect recommended accessory for cracks
or flaws. If such a crack or flaw is evident—discard the
wheel! The wheel should also be inspected whenever you
think the tool may have been dropped.
5. When starting the tool (with a new or replacement wheel
installed) hold the tool in a well protected area and let it run
for one minute. If the wheel has an undetected crack or
flaw, it should burst In less than one minute. Never start the
tool with a person in line with the wheel. This Includes the
operator.
6. In operation, avoid bouncing the wheel or giving it rough
treatment. If this occurs, stop the tool and inspect the
wheel.
7. Always use guards with depressed-center or flaring cup
grinding wheels.
8. Clean your tool out periodically following the procedure in
the maintenance section.
9. When using a 3 wire sender or grinder on job sites where
arc or resistance welding is being performed, the cord set
on this tool could be damaged by heavy welding currents
using the cord as a parallel return path. To maintain the
protection the ground wire provides, the cord should be
inspected frequently and replaced as necessary. Avoid
unnecessary contact between the metallic exterior of the
tool and grounded conductive surfaces.
FOR TOOLS EQUIPPED WITH 3-WIRE
CORD & REQUIRE GROUNDING,
PLEASE READ THE FOLLOWING:
GROUNDING
This tool should be grounded while in use to protect the
operator from electric shock. The tool is equipped with an
approved three-conductor cord and three prong grounding
type plug to fit the proper grounding type receptacle. The
green (or green and yellow) conductor in the cord is the
grounding wire. Never connect the green (or green and
yellow) wire to a live terminal. If your unit is for use on less
than 150 volts. It has a plug like that shown in Figure A. If it is
for use on 150 to 250 volts, it has a plug like that shown in
Figure D. An adapter, Figures B and C, is available for con­
necting Figure A plugs to two-prong receptacles. The green-
colored rigid ear, lug, etc., must be connected to a permanent
ground such as a properly grounded outlet box. No adapter is
available for a plug as shown in Figure D. ADAPTER SHOWN
IN FIGURES B & C IS NOT FOR USE IN CANADA.

FOR TOOLS EQUIPPED WITH 2-WIRE
CORDS, AND ARE DOUBLE INSULATED,
PLEASE READ THE FOLLOWING:
DOUBLE INSULATION
DOUBLE-INSULATED tools are constructed throughout
with TWO separate “layers” of electrical insulation or one
DOUBLE thickness of insulation between you and the tool’s
electrical system.
Tools built with this insulation system are not intended to be
grounded. As a result, yourtool is equipped with a two-prong
plug which permits you to use extension cords without
concern for maintaining a ground connection.
NOTE: DOUBLE INSULATION does not take the place of
normal safety precautions when operating this tool. The
insulation system is for added protection against injury
resulting from a possible electrical Insulation failure within
the tool.
CAUTION: When servicing all tools, USE ONLY IDENTICAL
REPLACEMENT PARTS. Repair or replace damaged cords.
EXTENSION CORDS
Double insulated tools have 2-wire cords and can be used
with 2-wire or 3-wire extension cords. Tools that have 3-wire
cords requiring grounding must only be used with extension
cords that have 3-prong grounding type plugs and 3-pole
receptacles. Make sure which construction your tool is
before choosing an extension cord. Only round jacketed
extension cords should be used, and we recommend that
they be listed by Underwriters Laboratories (U.L.) (C.S.A. in
Canada). If the extension will be used outside, the cord must
be suitable for outdoor use. Any cord marked as outdoor can
also be used for Indoor work. The letter “WA” on the cord
jacket Indicate that the cord Is suitable for outdoor use.
An extension cord must have adequate wire size (AWG or
American Wire Gauge) for safety, and to prevent loss of
power and overheating. The smaller the gauge number of the
wire, the greater the capacity of the cable, that is 16 gauge
has more capacity than 18 gauge. When using more than one
extension to make up the total length, be sure each Individual
extension contains at least the minimum wire size.
To determine the minimum wire size required, refer to the
chart below.

Before using an extension cord. inspect it for loose or
exposed wires, damaged insulation, and defective fittings.
Make any needed repairs or replace the cord if necessary.
Black & Decker has extension cords available that are U.L.
(C.S.A. in Canada) listed for outdoor use.
