INSULATION
Double insulation is a concept in safety, in electric
power tools which eliminates the need for the usual
three-wire grounded power cord. All exposed metal
parts are isolated from internal metal motor
components with protecting insulation. Double
insulated tools do not need to be grounded.
A

RULES
FOR SAFE OPERATION
(Continued)
WEAR PROPER APPAREL. Do not wear loose
clothing or jewelry that can get caught in tool's
moving parts and cause personal injury. Rubber
gloves and nonskid footwear are recommended
when working outdoors. Wear protective hair
covering to contain long hair and keep it from
being drawn into nearby air vents.
MAKE SURE YOUR EXTENSION CORD IS IN
GOOD CONDITION. When using an extension
cord, be sure to use one heavy enough to carry
the current your product will draw. An undersized
cord will cause a drop in line voltage resulting in
loss of power and overheating, A wire gage size
(A,W.G.) of at least 16 is recommended for an
extension cord 100 feet or less in length. A cord
exceeding 100 feet is not recommended. If in
doubt, use the next heavier gage. The smaller
the gage number, the heavier the cord.
ALWAYS WEAR SAFETY GLASSES. Everyday
eyeglasses have only impact-resistant lenses;
they are NOT safety glasses.

VARIABLESPEED
The following guidelines may be used in determining
correct speed for various applications:
See Figure 4.
Your hammer ddll has a variable speed control
selector designed to allow operator control and
adjustment of speed and torque limits. Speed and
torque can be increased or decreased by rotating the
variable speed control selector in the direction of the
arrows shown in figure 4.
Low speed is ideal when minimum speed and power
is required. For example: starting holes without center
punching, driving screws, mixing paint, and drilling in
ceramics.
VARIABLESPEED
CONTROLSELECTOR
High speed produces best results when maximum
power is required. For example: drilling in wood; soft
metals such as aluminum, brass, and copper;
concrete; and when using driving accessories.
Medium speed is suitable for drilling hard metals,
plastics, and laminates.
KEYLESS CHUCK

•
Plug your drill into power supply source.
•
Hold your drill firmly and place the bit at the point
to be drilled.
•
Depress the switch trigger to start your drill. Do not
lock the switch on for jobs where your drill may
need to be stopped suddenly.
•
Move the drillbit intoworkpiece applying only
enough pressure to keep the bit cutting. Do not
force your drill or apply side pressum to elongate a
hole. Let your drill and bit do the work.
See Figure 11.
j
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 variable 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.
,_
When drilling metals, use a light oil on the drill bit to
keep it from overheating. The oil will prolongthe life of
the bit and increase the drilling action.
Fig. 11
•
•
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
control when breaking through material. If not
prepared, this loss of control can result in
possible serious injury.
Depress and release the switch trigger to be sure
your drill is in off position before connecting it to
power supply.
Check the direction of rotation lever for correct
setting (forward or reveme). See Figure 3.
If the bit jams in workpiece or if the drill stalls, stop the
tool immediately. Remove the bit from the workpiece
and determine the mason for jamming.

All of the bearings in this tool are lubricated with a
sufficient amount of high grade lubricant for the life of
the unit under normal operating conditions. Therefore,
no further lubrication is required.
Avoid using solvents when cleaning plastic parts.
Most plastics are susceptible to damage from various
types of commemial solvents and may be damaged
by their use. Use clean cloths to remove dirt, carbon
dust, etc.
The use of any extension cord will cause some loss of
power. To keep the loss to a minimum and to prevent
tool overheating, use an extension cord that is heavy
enough to carry the current the tool will draw.
EXTENSION
CORDS
A wire gage size (A.W.G.) of at least 16 is
recommended for an extension cord 100 feet or less
in length. When working outdoors, use an extension
cord that is suitable for outdoor use. The cord's jacket
will be marked WA.
WARNING: Do not at any time let brake fluids,
gasoline, petroleum-based products, penetrating
oils, etc. come in contact with plastic parts. They
contain chemicals that can damage, weaken or
destroy plastic.
_k
It has been found that electdc tools are subject to
accelerated wear and possible premature failure when
they are used on fiberglass boats, sports cars,
wallboard, spackling compounds, or plaster. The
chips and grindings from these materials are highly
abrasive to electric tool parts such as bearings,
brushes, commutators, etc. Consequently, it is not
recommended that this tool be used for extended
work on any fiberglass material, wallboard, spackling
compounds, or plaster. During any use on these
materials it is extremely important that the tool is
cleaned frequently by blowing with an air jet.
CAUTION: Keep extension cords away from the
ddUing area and position the cord so that it will
not get caught on lumber, tools, etc., during
drilling operation.
WARNING: Check extension cords before each
use. If damaged, replace immediately. Never use
tool with a damaged cord since touching the
damaged area could cause electrical shock
resulting in serious injury.
Extension cords suitable for use with your hammer drill
are available at your nearest Sears Retail Store.
