OPERATION
DRILLING
See Figure 10.
n Attach auxiliary handle.
WARNING:
Do not force the tool. Forcing the tool can result in
jamming and loss of balance or footing, which could
result in personal injury.
n Depress and release switch trigger to be sure the drill is
in OFF position before connecting it to power supply.
n Check the direction of rotation lever for correct setting
(forward or reverse). See Figure 7.
n Secure the material to be drilled in a vise or with clamps
to keep it from turning as the drill bit rotates.
n Plug the drill into power supply source.
n Hold the drill firmly and place bit at the point to be
drilled.
WARNING:
To avoid loss of control or serious personal injury, al-
ways use both hands when operating this tool. Grip
the auxiliary handle firmly with one hand and grip the
switch handle of the tool with the other hand.
n Depress the switch trigger to start the drill. Do not lock
the switch ON for jobs where the drill may need to be
stopped suddenly.
n 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 drill and
bit do the work.
WARNING:
Be prepared for binding or bit breakthrough. When
these situations occur, drill has a tendency to grab
and kick opposite to the direction of rotation and
could cause loss of control when breaking through
materials. If not prepared, this loss of control can
result in possible serious injury.

HELPFUL HINTS
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. However, the
variable speed feature allows starting holes without center
punching if desired. To accomplish this, operate the drill at
a low speed until the hole is started.
Pulse mode allows you to drill on hard surfaces without a
center punch.
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 work piece or if the drill stalls, stop the
tool immediately. Remove the bit from the work piece and
determine the reason for jamming.
