fully. Learn its applications and limitations as well as the
specific potential hazards peculiar to this tool.
2. GROUND ALL TOOLS - UNLESS DOUBLE-INSULATED. If
tool is equipped with three-prong plug, it should be
plugged into a three-hole electrical receptacle. lf adapter
is used to accommodate two-prong receptacle, the adapter
wire must be attached to a known ground, Never remove
third prong.
3. KEEP GUARDS lN PLACE and in working order.
4. KEEP WORK AREA CLEAN. Cluttered areas and benches
invite accidents.
5. AVOID DANGEROUS ENVIRONMENT. Don't expose power
tools to rain. Don't use power tool in damp or wet locations.
And keep work area well lit.
5. KEEP CHILDREN AWAY. All visitors should be kept safe
distance from work area.
7. STORE IDLE TOOLS. When not in use, tools should be
stored in dry, high or locked-up place - out of reach of
c h i l d r e n .
8. DON'T FORCE TOOL. lt will do the job better and safer at
the rate for which it was designed.
9. USE RIGHT TOOL. Don't force small tool or attachment to
do the job of a heavy duty tool.
10. WEAR PROPER APPAREL. No loose clothing or jewelry to
get caught in moving parts. Rubber gloves and footwear
are recommended when working outdoors.
11. USE SAFETY GLASSES with-most tools. Also face or dust
mask if cutting operation is dusty.
12. DON'T ABUSE CORD. Never carry tool by cord or yank it
to disconnect from receptacle. Keep cord from heat, oil
and sharp edges.
13. SEGURE WORK. Use clamps or a vise to hold work. lt's
safer than using your hand and it frees both hands to
operate tool.
14. DON'T OVERREACH. Keep proper footing and balance at

ADDITIONAI. SAFETY RUIES FOR SAWS
1. DISCONNECT PLUG from power supply before changing
blades, making cutting depth or cutting angle adjustments,
inspecting, cleaning or when saw is not being used.
2. KEEP GUARDS lN PLACE and in working order. When re-
tracting the lower blade guard, always use the retracting
lever on the guard.
3. NEVER TIE BACK the lower blade guard or its retracting
lever.
4. KEEP HANDS AWAY from cutting area. Never reach under-
neath the material for any reason.
5. KEEP BI-ADE SHARP. Dull blades may cause the saw to
swerve or stall under pressure.
6. lF YOU DROP OR DAMAGE the saw, unplug it first; then
check to see if the blade and lower blade guard operate
freely before resuming operations.
7. NEVER REMOVE the spring attached ts the back of the
lower blade guard for any reason. lf spring should become
damaged, replace spring before attempting to use the saw.

i4oroR
Your Black & Decker tool is powered by a B&D-built motor.
Be sure your power supply agrees with voltage marked on name-
plate. Volts 5O/6O Hz means Alternating Gurrent only. Volts
DC-60 Hz means it will also operate on Direct Current. Voltage
variation of more than 1oo/o will cause loss of power and over-
heating. All B&D tools are factory-tested. lf this tool does not
operate, check the power supply line for blown fuses and the
plug and receptacle for proper contact.

GROUND'NG
This tool should be grounded while in use to protect the oper-
ator 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 con.
nect the green (or green and yellow) wire to a live terminal. lf
your unit is for use on less than 150 volts, it has a plug like
that shown in Figure A. lf it is for use on 150 to 250 volts, it
has a plug like that shown in Figure D. An adapter, Figures B
and G is available for connecting 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 plug shown in Figure D.
Adaptor shown in Figures B & C is Not for Use in Canada.

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. lf 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.
EXTENS'ON CORD
When using the tool at a considerable distance from power
sorlrce, a 3-conductor, grounding-type extension cord of ade-
quate size must be used for safety, and to prevent loss of
power and over-heating. To determine the minimum size wire
required in an extension cord, see table below:

Note: The lower the wire size number, the heavier the wire, and
the farther it will carry current without a voltage drop.
Use only three wire extension cords which have three.prong
g.rounding-type plugs and three-pole receptacles which accept
the tool's plug. Replace or repair damaged cords.
I.UBR'CAI'ON
Place two drops of machine oil in oil holqin the center of the
outer end of motor housing at approximately 15 hour intervals
of running time. lt is recommended that, at least once a year,
you take o.r send the tool to a B&D Service Center for a thorough
cleaning, inspection and lubrication of the gear case.
