Starting, Stopping and Controlling Speed
(Cat. No 2706-20)
1. To start the tool, grasp the handles firmly and pull
the trigger.
NOTE: An LED is turned on when the trigger is pulled.
2. To vary the speed, increase or decrease the pres-
sure on the trigger. The further the trigger is pulled,
the greater the speed.
3. To stop the tool, release the trigger. Make sure
the bit comes to a complete stop before laying the
tool down.
(Cat. No. 2757-20)
The tool may be operated at any speed from 0 to
full speed.
1. To start the tool, pull the trigger.
NOTE: An LED is turned on when the trigger is
pulled.
2. To vary the driving speed, increase or decrease
pressure on the trigger. The further the trigger is
pulled, the greater the speed, up to the maximum
speed set by the speed control.
3. To stop the tool, release the trigger and the electric
brake stops the tool instantly.
APPLICATIONS
To reduce the risk of electric shock,
WARNING
check work area for hidden pipes
and wires before drilling or driving screws.
(Cat. No. 2706-20)
Place the bit on the work surface and apply firm pres-
sure before starting. Too much pressure will slow the
bit and reduce drilling 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 in Wood, Composition Materials
and Plastic
When drilling in wood, composition materials and
plastic, select the
Start the drill slowly, gradually 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
splintering, back work with a piece of scrap wood. Se-
lect low speeds for plastics with a low melting point.
Drilling in Metal
When drilling in metal, select the
ating mode. 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
drill-only operating mode.

Drilling in Masonry
When drilling in masonry, select the
operating mode. Use high speed carbide-tipped bits.
Drilling soft masonry materials such as cinder block
requires little pressure. Hard materials like concrete
require more pressure. A smooth, even flow of dust in-
dicates 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.
Driving Screws and Nut Running
Drill a pilot hole when driving screws into thick or hard
materials. Select the
the torque selector collar to the proper position and
set the speed to low. Use the proper style and size
screwdriver bit for the type of screw you are using.
With the screwdriver bit in the screw, place the tip of
the screw on the workpiece and apply firm pressure
before pulling the trigger. Screws can be removed
by reversing the motor.
Overloading
Continuous overloading may cause permanent dam-
age to tool or battery pack.
Impacting Techniques
(Cat. No. 2757-20)
The longer a bolt, screw, or nut is impacted, the tighter it
will become. To help prevent damaging the fasteners or
workpieces, avoid excessive impacting. Be particularly
careful when impacting smaller fasteners because they
require less impacting to reach optimum torque.
Practice with various fasteners, noting the length of
time required to reach the desired torque. Check the
tightness with a hand-torque wrench. If the fasteners
are too tight, reduce the impacting time. If they are not
tight enough, increase the impacting time.
Oil, dirt, rust or other matter on the threads or under
the head of the fastener affects the degree of tightness.
The torque required to loosen a fastener averages
75% to 80% of the tightening torque, depending on
the condition of the contacting surfaces.
On light gasket jobs, run each fastener down to a
relatively light torque and use a hand torque wrench
for final tightening.
