IMPORTANT INFORMATION FOR RECHARGING HOT BATrERIES
When using your drift-driver continuously, the batteries in your battery pack will become hot. You should let a hot 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 lighton your battery charger to flash. When battery pack cools down, red light will glow continuously indicatingfast charging mode, 1 hour charge time. The green light indicates slow charging mode, requiring overnight charging for battedes to reach full charge. Once the battery pack cools down, itwill recharge battery pack infast 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 cimumstancas, return both the battery pack and charger to your nearest Sears repaircenter for electrical check.
"_k WARNING:
The operation of any power tool can result in foreign objects being thrown into your eyes, - which can result in severe eye damage. Before beginning power tool operation, always wear safety goggles or safety glasses with side shields and a full face shield when needed. We recommend Wide Vision Safety Mask for use over eyeglasses or standard safety glasses

See Figure 12.
A oonvenlent new feature provided with your ddfl is a level. It is recessed in the motor housing on top of your ddll. It can be used to keep ddll bits level dudng ddlfing operations.
LEVEL
Fig. 13
When drilling hard smooth surfaces use a center
punch to mark desired hole location. This will prevent the ddll 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 ddlled 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
drilled. Depress the switch tdgger to start tool.
Move the ddll bitinto the workpiece applying only
enough pressure to keep the bit cutting. Do not force
or apply side pressure to elongate e hole.
_1= WARNING: Be prepared for binding or bit
breakthrough. When these situations occur, ddll
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 sedous injury.
When drilling metals, use a light oil on the drill bit to
keep it from overheating. The oil willprolong the life of
the bit and increase the drilling action.
If the bit jams in workpiece or if the ddUstalls, release switch trigger immediately. Remove the bit from the
workpiece and determine the reason for jamming.

BATTERIES Your ddil's battery pack is equipped with 14 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 battedes. Handling of these battsdes, especially when
weadng rings and jewelry, could result in a sedous
bum.
To obtain the longest possible battery life, we suggest the following:
DO NOT abuse power tools. Abusive practices can
damage tool as well as workpiece. Only the parts shown on parts list, page fifteen, are
intended to be repaired or replaced by the customer. All other parts should be replaced by a qualified
service technician at an authorized service facility.
_k WARNING: Do not attempt to modify this tool or
create accessories not recommended for use
with this tool. Any such alteration or modification
is misuse and could result in a hazardous
condition leading to possible serious personal
injury.
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 battedes gradually lose their charge. The higher the temperature the quicker they lose their charge. If you store your tool for long pedods of time without using it, recharge the battedes every month or two. This practice will prolong battery
life.
OVERLOAD Your ddll has a built-inovedoad 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.
