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
letters “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 Е
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. BE
To determine the minimum wire size required, refer to the chart below.

power supply and switéh is in
“OFF” position.
2. Be sure the guard assembly i is
securely attached to the spindle
housing.
3. Put the backing flange onto the tool
spindle as shown.
4. Check rated speed on depressed
- center wheel. Never use wheel with |
rated speed lower that the speed
on the nameplate of the tool.
5. Place the Depressed Center Wheel |
“onthe tool spindle as shown.
_ 6. Thread the Clamp Washer on tool
~ spindle as shown. Hold the tool
- spindle by engaging the Spindle
“Lock Pin, and tighten Clamp
Washer with Spanner Wrench.
When using a Depressed Center
Wheel, hold the tool so that an angle
of approximately 30° exists between |
— the wheel and the work.
Wire Cup and
Knotted Wire
1. Disconnect tool from | power : source.
- Rest Grinder on its back with ©
spindle facing up.
2. Ensure that the rated speed of the
wire brush is equal to or higher
than the rated speed of the grinder
found onthe nameplate.
3. Thread brush onto spindle and
tighten.
4. Common applications for knotted
wire cup brush include cleaning
welds, angles, corners and paint
removal.
5. Usage of the knotted wire wheel
brush is the same as the wire cup
brush. They can also be used to
finish irregular surfaces and
corners. |
Maintenance
of Tool
Cleaning
Blowing dust and grit out of the
motor housing using compressed air
is a necessary regular maintenance
procedure. Dust and grit containing
particles from metal grinding often
accumulate on interior surfaces and
- could create an electrical shock
hazard if not frequently cleaned out.
ALWAYS WEAR SAFETY
GLASSES. |
CAUTION: NeVer úse vents |
or other harsh chemicals for cleaning
the non-metallic parts of the tool. Use
clean, dry rag only.
Lubrication
B&D tools are properly lubricated
| atthe factory and are ready for use.
“ Tools should be relubricated regularly
every sixty days to six months,
depending on usage. (Tools used
constantly on production for heavy-
duty jobs and tools exposed to heat
may require more frequent
lubrication.) This lubrication should
only be attempted by trained power
tool repairpersons such as those at
B&D Service Centers or in other
qualified service organizations.
Your tool is equipped with the
Black & Decker brush checkpoint
system. When the brushes become
worn out, the tool will automatically
| stop a and prevent biie to the
centers or other qua lified service
organizations.

. CONSIDER WORK AREA ENVIRONMENT. Don't expose power tools to rain. Don't use power
tools in damp or wet locations. Keep work area well lit.
. GUARD AGAINST ELECTRIC SHOCK. Prevent body contact with grounded surfaces. For
example: pipes, radiators, ranges, refrigerator enclosures.
KEEP CHILDREN AWAY. All visitors should be kept away from work area. Do not let vis itors
contact tool or extension cord.
. STORE IDLE TOOLS. When not in use, tools should be stored in dry, and high or locked- -up
place—out of reach of chi laren.

Rubber gloves and non- -skid footwear are recommended when working outdoors. Wear protective
— hair covering to contain long hair.
. USE SAFETY GLASSES. Also use face or dustmask if cutting operation is dusty.
10.
DON'T ABUSE CORD. Never carry tool by cord or yank it to disconnect from receptacle. Keep cord
from heat, oil, and sharp edges.
SECURE WORK. Use clamps or a vise to hold work. It's safer than using your hand and it frees both
hands to operate tool. |
DON'T OVERREACH. Keep proper footing and balance at all times.
MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for better and safe performance.
Follow instructions for lubricating and changing accessories. Inspect tool cords periodically and if

DISCONNECT TOOLS. When not in use, before servicing, and when changing accessories, such
as blades, bits, cutters.
REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to see that keys and
adjusting wrenches are removed from tool before turning it on.
AVOID UNINTENTIONAL STARTI ING. Don't carry plugged-in tool with finger on switch. Be sure
switch is off when plugging in
OUTDOOR USE EXTENSION CORDS. When tool is used outdoors, use only extension cords
intended. for use outdoors and so marked. More detailed information can be found on page 8.
STAY ALERT. Watch what you are doing. Use common sense. ‘Do not operate tool when you are
tired.
CHECK DAMAGED PARTS. Before 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 by an authorized service center unless otherwise indicated
elsewhere in this instruction manual. Have defective switches replaced by authorized service
center. Do not use tool if switch does not turn it on and off.

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 receptacie. The green
(or green and yellow) conductor in the
- cord is the grounding wire. Never
connect the green (or green and
уе! low) wire to a live terminal. Your
‘unit is for use on less than 150 volts
- and has a plug like that shown in
Figure A. An adapter, Figures B and C,
is available for connecting Figure A

E DOUBLE-INSULATED tools are
constructed throughout with TWO
separate “layers” of electrical
“insulation or one DOUBLE thickness ...

tool's electrical system. -
— Tools built with this insulation
system are not intended to be
grounded. As a result, your tool is
equipped with a two-prong plug which _
permits you to use extension cords
witnout concern for maintaining a
ground connection. See page 8 for
additional extension cord information.
NOTE: DOUBLE INSULATION |
does not take the place of normal
safety precautions when operating

NOTE: Examine the two figures —
at the left. One of them will represent:
your sander/grinder. Examine the one
that most closely resembles your tool
and find the SPINDLE LOCK PIN.
When using an abrasive disc,
hold the tool so that an angle of 10° to
15° exists between the disc and the
work, as shown in Figure 4. If only the . ” :
