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 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, requiring overnight charging for battedes 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 cimumstancas, return both the battery

pack and charger to your nearest Sears repair center 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 with side shields, available at Sears Retail Stores.

• Connect charger to power supply.

• Place battery pack in charger aligning raised rib in charger with groove in battery pack.

• Press down on battery pack to be sure contacts on battery pack engage properly with charger contacts.

• Red light should turn on. Red light indicates fast charging mode.

If red light is flashing, this indicates battery pack is deeply discharged or hot.

If battery pack is hot, red light should become

steady after battery pack has cooled down.

If battery pack is deeply discharged, red light should become steady after voltage has increased, normally within 30 minutes.

If after one hour red light is still flashing, this indicates a defective battery pack and should be replaced.

Green light on indicates battery pack is in slow

charging mode or fully charged.

Yellow light on and red light flashing indicates defective battery pack. Return battery pack to your

nearest Sears Repair Center for checking or replacing.

• When your battery pack becomes fully charged, the

red light will turn OFF and the green light will turn

ON.

• If you remove battery pack from charger and reinsert It immediately (less than 5 seconds) back in charger, the green light will come on

Indicating full charge and slow charging mode

until removed from charger, if you remove battery pack from charger and wait more than 5

seconds before reJnsertlng it back in charger, the charger will function normally.

• After normal usage, 1 hour of charging time is

required to be fully charged. A minimum charge time of 1-1/2 hours is required to recharge a completely discharged tool.

• The battery pack will become slightly warm to the touch while charging. This is normal and does not

indicate a problem.

• DO NOT place charger in an area of extreme heat

or cold. It will work best at normal room temperature.

LEVEL DRILLING

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 drill at 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 bit into 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.

11

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 ddU stalls, 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:

• 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-in ovedoad 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.
