WORK AREA

Keep your work area clean and well lit. Cluttered benches and dark areas invite accidents.
Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids,

gases, or dust. Power tools create sparks which may ignite the dust or fumes.
Keep bystanders, children, and visitors away while operating a power tool. Distractions can cause you

to lose control.

LECTRICAL SAFETY

Double insulated tools are equipped with a polarized plug (one blade is wider than the other .) This plug
will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it
still does not fit, contact a qualified electrician to install a polarized outlet. Do not change the plug in
any way. Double insulation eliminates the need for the three wire grounded power cord and

grounded power supply system.
Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refrigerators. There is

• Do not force tool. Use the correct tool for your applicatio

CAUTION! Always wear eye protection while operating this power tool.

LUSH-TO CUTTING

he exclusive, compact design of the motor housing and spindle housing permits extremely close cutting to floors,
orners and other difficult areas. When using an off-set shank blade for flush cutting reverse the blade as shown in

gure 3.

CAUTION: When sawing into walls, floors or wherever "live" electrical wires may be encountered, DO NOT
OUCH ANY METAL PARTS OF THE TOOL! Hold the saw only by its plastic handle to prevent electric shock if
ou saw into a "live" wire.

WOOD CUTTING

efore cutting any type of wood, be sure it is firmly anchored or clamped to prevent slippage. Check blade chart for

pe and length of blade necessary for best results. Place blade lightly against work to be cut, switch on saw motor

nd allow it to obtain maximum speed before applying pressure (see Figure 4). Always hold saw firmly with both

ands while cutting. Whenever possible, the saw shoe must be held firmly against the material being cut. This will

revent the saw from jumping or vibrating and minimize blade breakage.

OCKET CUTTING

he initial step in pocket cutting is to measure the surface area to be cut and mark clearly with a pencil, chalk or
criber. Insert pocket cutting blade in blade clamp, and tighten blade clamp securely. Next, tip the saw backward
ntil the back edge of the shoe is resting on the work surface and the blade is not touching the surface. Now switch

otor on, always permitting blade to attain maximum speed. Grip handle steadily and begin a slow, deliberate
pward swing with the handle of the saw, as shown in Figure 5. Blade will begin to feed into material. Always be
ure blade is completely through material before continuing with pocket cut.

OTE: In areas where blade visibility is limited, use the edge of the saw shoe as a guide. Lines for any given cut should

e extended beyond edge of cut to be made.

METAL CUTTING

his unit has different metal cutting capacities depending upon the type of blade used and the metal to be cut. Use

finer blade for ferrous metals (metals containing iron or steel) and a coarse blade for non-ferrous materials. In thin
auge sheet metals it is best to clamp wood to both sides of metal sheet. This will ensure a clean cut without exces­ve vibration or tearing of metal. Always remember not to force the saw as this reduces blade life and causes cost-

blade breakage.

OTE: When cutting metals you should spread a thin film of oil or other coolant along the line ahead of the saw cut

or easier operation and longer blade life. For cutting aluminum, kerosene is preferred.

UBRICATION

our tool was properly lubricated before leaving the factory. Once every year take or send your tool to a Black &

ecker service center, or authorized service station, for a complete cleaning, inspection and lubrication. Tools used
ontinuously on production jobs will need relubrication more often. Tools "out of service" for long periods should be

elubricated before being put back to work.When these tools are used on sports cars, boats etc., it has been found

at they are subject to accelerated wear and possible premature failure, as the fiberglass chips are highly abrasive

bearings, brushes, commutators and other parts.

onsequently it is not recommended that this tool be used for continuous production work on any fiberglass materi-

. During any use on fiberglass it is extremely important that the tool is cleaned frequently by blowing through with

n air jet.

CCESSORIES

he accessories listed in this manual are available at extra cost from your local dealer or Black & Decker service
enter.

CAUTION: The use of any accessory or attachment other than those recommended in this manual may be

azardous.

ROJECT TIPS

1. Cut only with sharp blades; they cut cleaner, faster and put less strain on the motor while cutting.

2. When cutting, always ensure that the shoe is resting against the workpiece. This will improve operator con-

ol and minimize vibration.

3. Blades available include both straight and slightly angled shanks. If you are using a straight shanked

lade in wood, hold the saw at a slight angle to the cutting plane to improve cutting performance.

4. For longer blade life, use bi-metal blades. These utilize a carbon steel back welded to high speed steel

eth making the blade more flexible and less prone to breaking.

MPORTANT

T o assure product SAFETY and RELIABILITY, repairs, maintenance and adjustments should be performed by

Black & Decker service centers or other qualified service organizations, always using Black & Decker

replacement parts.
