[] Loosen the chuck jaws from drill bit.
To loosen: grasp and hold the collar of the chuck
with one hand, while rotating chuck body with your

Depress the switch trigger to start your drill. Do not
lock the switch ON for jobs where your drill may
need to be stopped suddenly.
Move the drill bit into the workpiece applying only
enough pressure to keep the bit cuffing. Do not
force your drill or apply side pressure to elongate
a hole. Let your ddll and bit do the work. See
Figures 8 and 9.
ARNING: 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.
When drilling hard, smooth surfaces use a center
punch to mark the desired hole location. This will
prevent the ddll 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 your drill at a low speed until
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 work piece or if your drill stalls,
stop the tool immediately. Remove the bit from the
work piece and determine the reason for jamming.
See Figures 8 and 9.
A convenient feature provided with your drill is a level.
It is recessed in the motor housing on your ddll. It can
be used to keep drill bits level during both horizontal
and vertical drilling operations.
