IMPORTANT INFORMATION FOR RECHARGING HOT BATTERIES
When using your drill-driver continuously, the batteries in your battery pack will become hot. You should let ahot
battery pack cool down for approximately 30 minutes before attempting to recharge. When the battery pack
becomes discharged and is hot, this will cause the red light on your battery charger to flash. When battery pack
cools down, red light will glow continuously indicating fast charging mode, 1 hour charge time. The green light
indicates slow charging mode, requiringovernight charging for batteries to reach full charge. Once the battery
pack cools down, it will recharge battery pack in fast charging mode as normal.
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 YOUR DRILL-DRIVER" for normal recharging 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.
A WARNING:

It can be used to keep drill bits level during drilling
operations.
Fig. 11
Fig. 12
When drilling hard smooth surfacesuse a center punch
to mark desired hole location.This willprevent the drill
bitfrom slippingoff center as the hole is started. How-
ever, the low speed feature allows startingholes without
center punching if desired. To accomplishthis, simply
operate your drillat a low speed untilthe hole is started.
The material to be drilledshould be secured in a vise or
with clamps to keep it fromtuming as the drillbit rotates.
Hold tool firmly and placethe bitat the pointto be drilled.
Depress the switchtrigger to start tool.
Move the drill bitinto the workpieceapplyingonly
enough pressureto keep the bitcutting.Do not force or
apply side pressureto elongate a hole.
_llb 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 material. If not
prepared, this loss of control can result in
possible serious injury.
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 workpiece or if the drill stalls, release
switch trigger immediately. Remove the bit from the
workpiece and determine the reason for jamming.

BATTERIES
Your drill's battery pack is equipped with 11 nickel-
cadmium rechargeable batteries. Length of service
from each charging will depend on the type of work
you are doing.
The batteries in this tool have been designed to
provide maximum trouble free life. However, like all
batteries, they will eventually wear out. Do not
disassemble battery pack and attempt to replace the
batteries. Handling of these batteries, especially
when wearing rings and jewelry, could result in a
serious burn.
To obtain the longest possible battery life, we suggest
the following:
•Store and charge your batteries in a cool area.
Temperatures above normal room temperature
will shorten battery life.
•Never store batteries in a discharged condition.
Recharge them immediately after they are
discharged.
•All batteries gradually lose their charge. The
higher the temperature the quicker they lose their
charge. If you store your tool for long periods of
time without using it, recharge the batteries every
month or two. This practice will prolong battery
life.
OVERLOAD
Your drill has a built-in overload protector to protect
the motor during overloading or prolonged use. The
overload protector automatically activates to break the
circuit. When this occurs, allow your drill to cool a few
seconds before resuming operation.
