IMPORTANT SAFETY INSTRUCTIONS
WARNING; When using Electric Tools, basic safety precautions should always be
followed to reduce risk of fire, electric shock, and personal injury, including the following:
READ ALL INSTRUCTIONS
1. KEEP WORK AREA CLEANXIuttered areas and benches invite injuries.
2. 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.
3. GUARD AGAINST ELECTRIC SHOCK. Prevent body contact with grounded surfaces.
For example: pipes, radiators, ranges, refrigerator enclosures.
4. KEEP CHILDREN AWAY. All visitors should be kept away from work area. Do not let
visitors contact tool or extension cord.
5. STORE IDLE TOOLS. When not in use, tools should be stored in dry, and high or
locked-up place—out of reach of children.
6. DON’T FORCE TOOL. It will do the job better and safer at the rate for which it was
intended.
7. USE RIGHT TOOL. Don’t force small tool or attachment to do the job of a heavy-duty
tool. Don’t use tool for purpose not intended, for example, don’t use circular saw for
cutting tree limbs or logs.
8. DRESS PROPERLY. Do not wear loose clothing or jewelry. They can be caught in
moving parts. Rubber gloves and non-skid footwear are recommended when working
outdoors. Wear protective hair covering to contain long hair.
9. 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.
11. 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.
12. DON’T OVERREACH. Keep proper footing and balance at all time-.
13. 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 damaged have repaired by authorized service facility. In
spect extension cords periodically and replace if damaged. Keep handles dry, clean,
and free from oil and grease.
14. DISCONNECT TOOLS. When not in use, before servicing, and when changing
accessories, such as blades, bits, cutters.
15. REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to see that
keys and adjusting wrenches are removed from tool before turning it on.
16. AVOID UNINTENTIONAL STARTING. Don’t carry plugged-in tool with finger on
switch. Be sure switch is off when plugging in.
17. OUTDOOR USE EXTENSION CORDS. When tool is used outdoors, use only extension
cords intended for use outdoors and so marked.
18. STAY ALERT. Watch what you are doing. Use common sense. Do not operate tool
when you are tired.
19. 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 mov
ing 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.
20. DO NOT OPERATE portable electric tools near flammable liquids or in gaseous or
explosive atmospheres. Motors in these tools normally spark, and the sparks might
ignite fumes.
CIRCULAR SAW SAFETY INSTRUCTIONS
1. Disconnect plug from power supply before changing blades, making cutting depth or
cutting angle adjustments, inspecting, cleaning or when saw is not used.
2. Keep guards in place and in working order. Never wedge or tie lower guard open.
Check operation of lower guard before each use. Do not use if lower guard does not
close briskly over saw blade. CAUTION : If saw is dropped, lower guard may be bent,
restricting full return.
3. KEEP BLADES CLEAN AND SHARP. Sharp blades minimize stalling and kick back.
4. DANGER: KEEP HANDS AWAY FROM CUTTING AREA. (See fig. 7) Keep hands away
from blades. Do not reach underneath work while blade is rotating. Do not attempt to
remove cut material when blade is moving. CAUTION: Blades coast after turn off.
5. SUPPORT LARGE PANELS. Large panels must be supported as shown in FIGURE 8
tominimizethe risk of blade pinching and kick back. When cutting operation requires
the resting of the saw on the work-piece, the saw shall be rested on the larger portion
and the smaller piece cut off. (See FIGURE 7)
6. USE RIP FENCE. Always use a fence or straight edge guide when ripping.
7. GUARD AGAINST KICK BACK. Kick back occurs when the saw stalls rapidly and is
driven back towards the operator. Release switch immediately if blade binds or saw
stalls. Keep blades sharp. Support large panels as shown in FIGURE 8. Use fence or
straight edge guide when ripping. Don’t force tool. Stay alert, exercise control. Don’t
remove saw from work during a cut while the blade is moving.
8. LOWER GUARD. Raise lower guard with the retracting handle.
9. ADJUSTMENTS. Before cutting be sure depth and bevel adjustments are tight.
10. USE ONLY CORRECT BLADES IN MOUNTING. Do not use blades with incorrect size
holes. Never use defective or incorrect blade washers or bolts.
11. AVOID CUTTING NAILS. Inspect for and remove all nails from lumber before cutting.
SAVE THESE INSTRUCTIONS
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 threeprong 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 twoprong 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.

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 Cen
ters 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, THESE INSTRUCTIONS

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. 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.
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.SA in Canada) listed for outdoor use.

MOTOR
Your Black & Decker tool is powered by a B & D-built motor. Be sure your power
supply agrees with the nameplate marking.
Volts 50/60 Hz or “AC only” means your tool must be operated only with alter
nating current and never with direct current. Volts DC-60Hz or AC/DC means your
tool may be operated with either alternating or direct current.
Voltage decrease 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.
