TRIGGER SWITCH & FORWARD / REVERSE / LOCK BUTTON
A forward / reverse control button determines the direction of the tool and also serves as a
lock off button. To select forward rotation, release the trigger switch and depress the forward
/ reverse control button as shown in Figure 5. To select reverse, depress the forward / reverse
control button the opposite direction. The center position of the control button locks the tool
in the off position.
AUTOMATIC ELECTRIC BRAKE
The power unit is equipped with an electric blade brake which stops the tool heads within 1-1/2
seconds of trigger release. This is automatic and requires no adjustment.
Occasionally, under certain conditions, the brake will not function properly and won't stop the
tool in the 1-1/2 seconds as discussed above. If this condition occurs, turn the tool on and off
four or five times. If the problem still persists, have the tool serviced at a Black & Decker serv-
ice center or company authorized service facility.
Note: Ensure the forward / reverse switch is in the center (lock off) position.
KEYLESS CHUCK
To insert a drill bit or other accessory:
1. Grasp the rear half of the chuck with one hand and use your other hand to rotate the front
half in the counterclockwise direction, (Fig.6).
2. Insert the bit or other accessory fully into the chuck, and tighten securely by holding the
rear half of the chuck and rotating the front portion in the clockwise direction as viewed from
the chuck end.
WARNING: Do not attempt to tighten drill bits (or any other accessory) by gripping the front
part of the chuck and turning the tool on. Damage to the chuck and personal injury may occur
when changing accessories.
TORQUE CONTROL
The torque adjustment collar shown in Fig. 5 has 24 settings. There are 23 screwdriving set-
tings and a drilling setting which is represented by the drill bit symbol. For screwdriving pro-
ceed as follows:
Set the torque adjustment to position "1". Fit and tighten the first screw. If the clutch of your
drill starts to ratchet before the screw is correctly seated, rotate the adjustment collar as nec-
essary, until the clutch slips when the head of the screw is flush with the surface of the mate-
rial. Use this torque setting for the rest of the screws.
DRILLING TIPS
Always remove batteries from drill when attaching or removing accessories. When using a
keyless chuck, hand tighten firmly.
• Use sharp drill bits only.
• Support and secure work properly, as instructed in the Safety Instructions.
• Use appropriate and required safety equipment, as instructed in the Safety Instructions.
• Secure and maintain work area, as instructed in Safety Instructions.
• Run the drill very slowly, using light pressure, until the hole is started enough to keep the drill
bit from slipping out of it.
• Apply pressure in a straight line with the bit. Use enough pressure to keep the bit biting but
not so much as to stall the motor or deflect the bit.
• Hold the drill firmly to control its twisting action..
• DO NOT CLICK THE TRIGGER OF A STALLED DRILL OFF AND ON IN AN ATTEMPT TO
START IT. DAMAGE TO THE DRILL CAN RESULT.
• Minimize stalling on breakthrough by reducing pressure and slowly drilling through the last
part of the hole.
• Keep the motor running while pulling the bit out of a drilled hole. This will help reduce jam-
ming.
• Use a cutting lubricant when drilling metals. The exceptions are cast iron and brass which
should be drilled dry. The lubricants that work best are sulphurized cutting oil or lard oil.
Bacon grease will also serve.
• When using twist drill bits to drill holes in wood, it will be necessary to pull the bits out fre-
quently to clear chips from the flutes.
DRILLING
• Make sure switch turns drill on and off.
WARNING: It is important to support the work properly and to hold the drill firmly to prevent
loss of control which could cause personal injury.
CIRCULAR SAWING
WARNING: Always remove battery from tool before any of the following operations.
ATTACHING AND REMOVING THE BLADE
NOTE: This saw is designed to cut wood and plastic. Do not use masonry or metal cut-
ting blades.
The first time the blade bolt is removed from saw without a blade installed, it may be neces-
sary to place the blade wrench on the bolt head and tap it sharply in the counter clockwise
direction.
Assemble blade and clamp washers, as shown in Fig. 11 The blade wrench is stored on the
side of the circular saw head above the spindle lock button (Figure 12).To prevent blade rota-
tion while tightening the blade clamping screw, depress the spindle lock button as shown in
Fig. 15. Tighten the blade clamping screw securely.
OPERATING INSTRUCTIONS
WARNING: To reduce the risk of serious personal injury, read, understand and follow all
important safety warnings and instructions prior to using tool.
GENERAL CUTS (IMPORTANT: Read safety warnings and instructions.
GUARD AGAINST KICKBACK
With battery removed, follow all assembly, adjustment and set up instructions.
Make sure lower guard operates. Select the proper blade for the material to be cut.
• Measure and mark work for cutting.
• Support and secure work properly (See Safety Rules and Instructions).
• Use appropriate and required safety equipment (See Safety Rules).
• Secure and maintain work area (See Safety Rules).
• With battery inserted, make sure switch turns saw on and off.
USING THE CIRCULAR SAW
Use both hands on the power unit to control the circular saw and run the saw at fulll speed at
all times.
The circular saw is equipped with a switch to prevent running in a reverse direction. To start
the saw, push in on the forward/reverse button from the blade side of the saw. Next, push in
on the blade release button shown in Figure 12. Squeeze the trigger and the tool will run. At
this time the button can be released. The tool will continue to run as long as the trigger is
depressed.
To turn the tool off, release the trigger switch. There is no provision for locking the tool on, and
the switch should never be locked on by any other means.
KERF PLATE
Align mark on kerf plate (Figure 14) with drawn pencil line and advance blade into cut.
POCKET CUTTING (SEE FIG. 15)
Pocket cutting is used to cut a hole in a piece of material without cutting from the side.
• Measure and mark work.
• Tilt saw forward and rest front of the shoe on material to be cut. Align so that cut will begin at
the back of the drawn rectangle.
• Using the retracting lever, retract blade guard to an upward position, with the blade just
clearing the material, start motor and gradually lower the saw into the material.
WARNING: As blade starts cutting the material, release the retracting lever immediately.
• Never tie the blade guard in a raised position.
• When the shoe rests flat on the material being cut, complete the cut in forward direction.
• Allow the blade to come to a complete stop before lifting saw from material.
• When starting each new cut, repeat the above steps.
