For reverse (counterclockwise) rotation,
push in the control switch from the left
side of the tool (Fig. 7). Check direction
of rotation before use.

To lock the trigger, push the control switch
to the center position (Fig. 8). The trigger
will not work while the control switch is in
the center locked position. Always lock the
trigger or remove the battery pack before
performing maintenance, changing acces-
sories, storing the tool and any time the
tool is not in use.

Starting, Stopping & Controlling
Speed
1. To start the tool, pull the trigger.
2. To stop the tool, release the trigger
and an electric brake stops the tool
instantly.
All models feature variable speed control.
To vary the speed, simply increase or de-
crease pressure on the trigger. The further
the trigger is pulled, the greater the speed.
Drilling
Set the torque selector collar to the drill
position
Place the bit on the work surface and ap-
ply firm pressure before starting. Too much
pressure will slow the bit and reduce drill-
ing efficiency. Too little pressure will cause
the bit to slide over the work area and dull
the point of the bit.
If the tool begins to stall, reduce pressure
slightly to allow the bit to regain speed. If
the bit binds, reverse the motor to free the
bit from the workpiece.
Drilling
Materials and Plastic
When drilling in wood, composition materi-
als and plastic, start the drill slowly, gradu-
ally increasing speed as you drill. When
drilling into wood, use wood augers or
twist drill bits. Always use sharp bits.
When using twist drill bits, pull the bit out of
the hole frequently to clear chips from the
bit flutes. To reduce the chance of splin-
tering, back work with a piece of scrap
wood. Select low speeds for plastics with
a low melting point.

When drilling in metal, use high speed steel

twist drills or hole saws. Use a center
punch to start the hole. Lubricate drill bits
with cutting oil when drilling in iron or steel.
Use a coolant when drilling in nonferrous
metals such as copper, brass or aluminum.
Back the material to prevent binding and
distortion on breakthrough.
Drilling in Masonry
When drilling in masonry, select the
hammer-drill
(Cat. No. 0613-20, 0614-20, and 0624-20
only). Use high speed carbide-tipped bits.
Drilling soft masonry materials such as cin-
der block requires little pressure. Hard ma-
terials like concrete require more pressure.
A smooth, even flow of dust indicates the
proper drilling rate. Do not let the bit spin in
the hole without cutting. Do not use water
to settle dust or to cool bit. Both actions
will damage the carbide.
