IMPORTANT INFORMATION FOR RECHARGING HOT BATTERIES
When using your drill-driver continuously, the batter-
ies in your battery pack will become hot. You should
let a hot battery pack cool down for approximately 30
minutes before attempting to recharge.
Note: This situation only occurs when continuous use
of your drill causes the batteries to become hot. It
does not occur under normal circumstances. Refer to
"CHARGING BATTERY PACK" for normal recharg-
ing of batteries. If the charger does not charge your
battery pack under normal circumstances, return both
the battery pack and charger to your nearest Sears
repair center for electrical check.

,_ WARNING: Always wear safety goggles or
safety glasses with side shields when operating
tools. Failure to do so could result in objects
being thrown into your eyes, resulting in possible
serious injury.
DRILLING
See Figure 9.
Fig. 9
When drilling hard smooth surfaces use a center
punch to mark desired hole location. This will prevent
the drill bit from slipping off center as the hole is
started. However, the low speed feature allows
starting holes without center punching if desired. To
accomplish this, simply operate your drillat a low
speed until the hole is started.
The material to be drilled should be secured in a vise
or with clamps to keep it from turning as the drill bit
rotates.
Hold tool firmly and place the bit at the point to be
ddlled. Depress the switch trigger to start tool.
Move the drill bit into the workpieca applying only
enough pressure to keep the bit cutting. Do not force
or apply side pressure to elongate a hole.
_k 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 rotationand could cause loss of
control when breaking through matedal. If not
prepared, this loss of control can result in
possible sedous injury.
When drilling metals, use a light oil on the drill bit to
keep itfrom overheating. The oil will prolong the life of
the bit and increase the drilling action.
If the bit jams in workpiece or ifthe drill stalls, release
switch trigger irnmediately. Remove t,le bit from the
workpiece and determine the reason for jamming.
LEVEL DRILLING
See Figure 10.
A convenient feature provided with your drill is a level.
It is recessed in the motor housing on top of your drill.
It can be used to keep drill bit level during ddlling
operations.
