WARNING:
Do not hold the chuck body with one hand and use the
power of the drill to tighten the chuck jaws on the drill
bit. The chuck body could slip in your hand, or your
hand could slip and come in contact with the rotating
drill bit. This could cause an accident resulting in serious
personal injury.
WARNING:
Always unplug the tool when installing or removing bits,
adjusting settings, or when the tool is not in use. Failure
to unplug the tool may result in accidental starting and
serious personal injury.
INSTALLING BITS
See Figure 2 - 3, page 10.
 Unplug the drill.
 Open or close the chuck jaws to a point where the open-
ing is slightly larger than the bit size you intend to use.
Also, raise the front of the drill slightly to keep the bit from
falling out of the chuck jaws.
 Insert the drill bit (not included).
WARNING:
Make sure to insert the drill bit straight into the chuck
jaws. Do not insert the drill bit into the chuck jaws at
an angle then tighten, as shown in figure 3. This could
cause the drill bit to be thrown from the drill, resulting in
possible serious personal injury or damage to the chuck.
 Tighten the chuck jaws securely on the bit.
NOTE: Rotate the chuck body in the direction of the
arrow marked LOCK to close the chuck jaws. Do not use
a wrench to tighten or loosen the chuck jaws.
REMOVING BITS
See Figure 2, page 10.
 Unplug the drill.
 Open the chuck jaws.
NOTE: Rotate the chuck body in the direction of the arrow
marked UNLOCK to open the chuck jaws. Do not use a
wrench to tighten or loosen the chuck jaws.
 Remove the drill bit.
OPERATION
LOCK-ON BUTTON
See Figure 4, page 10.
This drill is equipped with a lock-on feature, which is
convenient for continuous drilling for extended periods of
time.
To lock-on:
 Depress the switch trigger.
 Push in and hold the lock-on button, located on the side
of the handle.
 Release the switch trigger.
 Release the lock-on button and the drill will continue
running.
 To release the lock, depress and release the switch trigger.
If the lock-on feature is engaged during use and the drill
becomes disconnected from the power supply, disengage
the lock-on feature immediately.
WARNING:
Before connecting the drill to a power supply source,
always check to be sure it is not in lock-on position
(depress and release the switch trigger). Failure to ensure
that it is not locked-on could result in accidental starting
of the drill resulting in possible serious injury. Do not lock
the switch trigger in applications where the drill may need
to be suddenly stopped.
DRILLING
See Figures 5 - 6, pages 10 - 11.
A level is located on the top of the motor housing to help
keep the drill bit level during use.
 Depress and release the switch trigger to be sure the drill
is in the OFF position before connecting it to a power
supply.
 Check the direction of rotation selector for the correct
setting (forward or reverse).
 Secure the material to be drilled in a vise or with clamps
to keep it from turning as the drill bit rotates.
 Plug the drill into power supply. Hold the drill firmly and
place the bit at the point to be drilled.
 Depress the switch trigger to start the drill.
 Move the drill bit into the workpiece, applying only enough
pressure to keep the bit cutting. Do not force the drill or
apply side pressure to elongate a hole. Let the tool do
the work.
