1. ALWAYS WEAR SAFETY GOGGLES WHEN USING THIS TOOL.
2. DO NOT USE GRINDING WHEELS ON THIS TOOL.
3. FOLLOW ALL SAFETY RULES LISTED ON NEXT PAGE OF THIS MANUAL
4. USING A DUST MASK IS RECOMMENDED.
MOTOR
Your tool Is powered by a Black & Decker built motor. Be sure your power supply
agrees with nameplate marking. VOLTS AC means Alternating Current (25 to 60
cycles) ONLY. VOLTS AC/DC means it will also operate on Direct Current. Voltage
variation of more than 10% will cause loss of power and over-heating. All B&D tools
are factory-tested; if this tool does not operate, check the power supply.
BRUSHES
Carbon Brushes should be regularly inspected for wear. To inspect brushes, unplug
tool, unscrew the plastic brush inspection caps (located in top and bottom motor
housing) and the spring and brush assemblies may be withdrawn from the tool.
Keep brushes clean and sliding freely in their guides. Carbon brushes have varying
symbols stamped into them, and if the brush is worn down to the line closest to the
spring, they must be replaced. New brush assemblies are available at Service
Centers; see TOOLS, ELECTRIC in the Yellow Pages.
EXTENSION CORD
When using the tool at a considerable distance from power source, a 3 conductor,
grounding-type extension cord of adequate size must be used for safety, and to
prevent loss of power and over-heating. Use the table below to determine the mini
mum wire size required.
Use only three wire extension cords which have three-prong grounding-type plugs and
three-pole receptacles which accept the tool's plug. Replace or repair damaged cords.

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 connecting Figure A plugs to two-prong recep
tacles. 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.
GROUNDING (continued)
0«}UNDEO OUTLET BOX
We recommend that you NEVER disassemble the tool or try to
do any rewiring in the electrical system. Any repairs should be
performed only by B&D Service Centers or other qualified
service organizations. Should you be determined to make a
repair yourself, remember that the green colored wire is the
“grounding" wire. Never connect this green wire to a “live”
terminal. If you replace the plug on the power cord, be sure to
connect the green wire only to the grounding (longest) prong
on a 3-prong plug.
To start tool, depress trigger: to stop, release trigger. To lock
trigger in “ON” position for continuous operation, depress
trigger, push in locking button, and release trigger. To release
locking mechanism and turn off tool, depress trigger and release.
ATTACHING DISCS
1. Place Backing Pad and sanding
disc on spindle of toot.
2. Screw Clamp Washer PARTIALLY
on the spindle.
3. V'/ith one hand, depress the spin
dle lock button and hold the
button down. Grasp the pads and
sanding disc with the other hand
Rg. I
and turn by hand to tighten the
entire assembly (fig. 1).
To remove pads and discs: depress
spindle lock button: grasep the pads
and disc: and turn pad and disc
assembly in opposite direction.
OPERATION
Grasp the control handies firmly and
operate the tool freely without forced
effort or unnecessary pressure. For
maximum efficiency, the tool must
be positioned so that the sanding
disc is at the proper angle to the
work. Fig., 2 (marked “RIGHT”) illus
trates how the tool is tipped slightly
in order to let the maximum amount
of abrasive contact the work without
affecting the smoothness of the sand
ing action. Fig. 3 and Fig. 4 (marked
“WRONG”) show incorrect positions
which allow either too little or too
much abrasive contact. If only the
outer edge of the sanding, disc is
used (as in Fig. 3), a rough cut sur
face will result. If the sanding disc
is pressed flat against the work (as
in Fig. 4), the cutting action will be
irregular and bumpy, and the toot
will be difficult to control.

CLEANING
Blowing dust and grit out of the main
housing by means of an air hose is
recommended and may be done as
often as dirt is seen collecting in and
around the ventilator vents. The
motor should be running while air
is being blown into the air vents.
