OPERATION
USING THE AUXILIARY HANDLE ASSEMBLY
See Figure 6, page 14; figure 7, page 15.
An auxiliary handle is packed with the drill for ease of
operation and to help prevent loss of control. The handle can
be rotated 360°, and it can also be mounted on the opposite
side for left hand use.
To adjust the auxiliary handle assembly,
Loosen the handle assembly by turning the handle
counterclockwise.
Rotate the auxiliary handle assembly to the desired
operating position.
Securely tighten by turning the auxiliary handle
clockwise.
Be sure the auxiliary handle is securely tightened against the
depth stop clamp. This secures the depth stop rod at the
desired depth of cut. It also secures the auxiliary handle.
NOTE: For convenience and ease of starting threads, the
hex nut has been trapped inside the molded slot in the
auxiliary handle.
The depth stop rod helps control the depth of drilled
holes.
NOTE: When properly installed, the teeth on the depth stop
rod should be aligned with the teeth indicator on the depth
stop clamp.
Adjust the depth stop rod so that the drill bit extends beyond
the end of the rod to the required drilling depth.
When drilling holes with the depth stop rod installed, the
desired hole depth has been reached when the end of the
rod comes in contact with the surface of the workpiece.
SELECTING HAMMER MODE OR DRILLING
MODE
See Figure 8, page 15.
To adjust for type of drilling, slide the selector on top of the
motor housing to hammer mode or drilling mode. The ham-
mer mode symbol is on the right and the drill bit symbol is
on the left.
NOTE: The hammer drill has not been designed for reverse
hammering.
Use carbide-tipped bits and select hammer mode when
drilling in hard materials such as brick, tile, concrete, etc.
Select normal drill mode when drilling with twist drills, hole
saws, etc., in soft materials.
LOCk-ON BUTTON
See Figure 9, page 15.
This drill is equipped with a lock-on feature, which is conve-
nient 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 Figure 10, page 15.
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.
WARNING:
Be prepared for binding at bit breakthrough. When
these situations occur, the drill has a tendency to
grab and kick in the opposite direction and could
cause loss of control when breaking through
material. If not prepared, this loss of control can
result in possible serious injury.
When drilling hard, smooth surfaces, use a center punch
to mark the desired hole location. This will prevent the
drill bit from slipping off-center as the hole is started.
When drilling metals, use a light oil on the drill bit to keep
it from overheating. The oil will prolong the life of the bit
and increase the drilling action.
If the bit jams in the workpiece or if the drill stalls, stop
the tool immediately. Remove the bit from the workpiece
and determine the reason for jamming.
