SWITCHES
Pulling the Trigger Switch turns the tool "ON"; releasing the
trigger turns the tool "OFF" To lock switch "ON", depress
trigger, hold In locking button, and release trigger. Release but
ton and tool will stay "ON". To then turn tool "OFF", depress
and release trigger.
The reversing switch is mounted on the top of the tool and for
driving fasteners is placed in the forward position. To reverse
rotation for fastener removal, first release trigger to turn tool
"OFF", then move toggle switch back to reverse tool.
For maximum tool life avoid excessive reverse operation. For
those operations where the tool is used primarily in reverse, see
your Black and Decker Distributor or Black and Decker Service
Center.
MOTOR
Your Black and Decker tool is powered by a B&D 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 following: Supply line for blown
fuses; plug and receptacle for contact; carbon brushes for
contact.
COMMUTATOR AND BRUSHES
Inspect carbon brushes often. Replace when brushes are worn
down to the identifying letter or groove or when spring exerts
insufficient pressure to hold brush against commutator. Keep
brushes clean and sliding freely in guides. Inspect commutator
for dirt and exessive wear. If dirty or rough, clean lightly with
very fine sandpaper (not emery cloth). If badly worn or
grooved, send tool to our nearest service station for repair
(see back page).
GROUNDING
These units are equipped with approved 3-conductor cord and
3-prong grounding type attachment plug to be used with the
proper grounding type receptacle, in accordance with the
National Electrical Code and Canadian Electrical Code.
IF YOUR UNIT REQUIRES LESS THAN 150 VOLTS IT HAS A
PLUG THAT LOOKS LIKE FIG. "A". It will fit directly into the
proper type of 3-wire grounding receptacle. The unit is then
grounded automatically each time it Is plugged in.
Shown in Fig. "B" is a special grounding adaptor (not allowed
in Canada by the Canadian Electrical Code) which is available
from your dealer and will permit using a 2-wire receptacle.
The green grounding wire extending from the side of the
adapter must be connected to a PERMANENT GROUND.
IF THE UNIT REQUIRES FROM 150 TO 250 VOLTS, IT HAS A
PLUG LIKE FIGURE "C". No adapter is available and it should
be used in the proper standard matching 3-wire grounding
receptacle.

CABLE
The cable is the "life line" of your tool—keep it clean by
wiping it off occasionally. Keep it out of oils and greases which
ruin the rubber. Coil it neatly when not in use and avoid
dragging it across sharp surfaces or using it as a handle to lift
the tool. When using the tool at a considerable distance from
power source, an extension cable of adequate size must be
used to prevent loss of power and over-heating. Use the table
below for 115-volt tools. For 220-volt tools, use wire size corres
ponding to an extension length of V2 the contemplated length.
