FOR
RECHARGING
HOT BATTERIES
When using your hammer drill continuously, the batteries in your battery pack will be.t_omehot. 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 charge_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 ovemight 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 HAMMER DRILL" for normal recharging of batteries. If the charger does not charge your battery pack under normal circumstances, retum both the
battery pack and charger to your nearest Sears repair center for electrical check.
CHARGER
See Figure 2.
Your charger has a "key hole" hanging feature for convenient, space saving storage. Screws should be installed
so that center distances are 1-7/16 inches apart.

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.
If battery pack is deeply discharged, red light should
become steady after voltage has increased,
normally within 30 minutes.
WARNING: Do not allow familiarity with your
hammer drill to make you careless. Remember
that a careless fraction of a second is sufficient
Green light on indicates battery pack is in slow
charging mode or fully charged.
If after one hour red light is stillflashing, this
indicates a defective battery pack and should be
replaced.
Yellow light on and red light flashing indicates

See Figure 4.
Your ddll has a two-speed gear train designed for

speed. When using drill in the HI speed range, speed
will increase and unit will have less power and torque.
When using drill in the LO speed range, speed will
decrease and unit will have more power and torque.
Use HI speed for fast drilling or driving applications

DRILLING
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.
See Figure 16.
If the bit jams in workpiece or if the ddll stalls, release
switch trigger immediately. Remove the bit from the
workpiece and determine the reason for jamming.

For maximum performance, use high speed steel
bits for wood ddlling.
•
Turn mode selector ring on hammer ddlt to normal
ddlling action.
•
Begin drilling at a very low speed to prevent the bit
from slipping off the starting point. Increase the
speed as the ddll bit bites into the material.
•
When drilling through holes, place a block of wood
behind the workpiece to prevent ragged or
splintered edges on the back side of the hole.
•
Do not lock the trigger on forJobs where your
hammer drill may need to be stopped
suddenly.
METAL

For maximum performance, use high speed steel
bits for metal or steel drilling.

When drilling hard smooth surfaces use a canter

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 pbnching if desired. To
accomplish this, simply operate your drill at a low
speed until the hole is started.

DRILLING
When drilling large holes in metal, we recommend
that _ou ddll with a small bit at first, then finish with
a larger bit. Also, lubdcate the bit with oil to
improve dqlling action and increase bit life.
MASONRY
•
DRILLING
For maximum performance use carbide-tipped
masonry impact bits when ddlling holes in
bdck, tile, concrete, etc.
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 rotation and could cause loss of
•Tum
control when breaking through material. If not
prepared, this loss of control can result in
possible serious injury.
•
Apply light pressure and medium speed for best
results in brick.
•
Apply additional pressure and high speed for hard
matadals such as concrete.
•
When drilling holes in tile, practice on a scrap
piece to determine the best speed and pressure.
