RULES FOR SAFE OPERATION

DOUBLE INSULATION is a concept in safety, in electric

power tools, which eliminates the need for the usual three
wire grounded power cord and grounded supply system.
Wherever there is electric current in the tool there are two
complete sets of insulation to protect the user. All exposed
metal parts are isolated from internal metal motor components
with protecting insulation.

WARNING:

Do not attempt to operate this tool until you have read
thoroughly and understand completely all instructions,
safety rules, etc. contained in this manual. Failure to
comply can result in accidents involving fire, electric
shock, or serious personal injury. Save owner's manual
and review frequently for continuing safe operation, and
instructing others who may use this tool.

READ ALL INSTRUCTIONS

1. KNOW YOUR POWER TOOL. Read owner's
manual carefully. Learn its applications and
limitations as well as the specific potential hazards
related to this tool.

2. GUARD AGAINST ELECTRICAL SHOCK by
preventing body contact with grounded surfaces.
For example: Pipes, radiators, ranges, refrigerator
enclosures.

3. KEEP GUARDS IN PLACE and in working order.

4. KEEP WORK AREA CLEAN. Cluttered areas and
benches invite accidents.

5. AVOID DANGEROUS ENVIRONMENT. Don't use
power tool in damp or wet locations or expose to
rain. Keep work area well lit.

6. KEEP CHILDREN AND VISITORS AWAY. All
visitors should wear safety glasses and be kept a
safe distance from work area. Do not let visitors
contact tool or extension cord.

7. STORE IDLE TOOLS. When not in use tools
should be stored in a dry and high or locked-up
place - out of the reach of children.

8. DON'T FORCE TOOL. It will do the job better and
safer at the rate for which it was designed.

9. USE RIGHT TOOL. Don't force small tool or
attachment to do the job of a heavy duty tool. Don't
use tool for purpose not intended - for example - A
circular saw should never be used for cutting tree
limbs or logs.

10. WEAR PROPER APPAREL. Do not wear loose
clothing or jewelry that can get caught in tool's

IMPORTANT - Servicing of a tool with double insulation
requires extreme care and knowledge of the system and
should be performed only by a qualified service technician.
For service we suggest you return the tool to your nearest
Sears Store for repair. Always use original factory replacement
parts when servicing.

WARNING:

The double insulated system is intended to protect the
user from shock resulting from a break in the tool's
internal wiring. Observe all normal safety precautions
related to avoiding electrical shock.

moving parts and cause personal injury. Rubber
gloves and non-skid footwear are recommended
when working outdoors. Wear protective hair
covering to contain long hair and keep it from being
drawn into nearby air vents.

11. ALWAYS WEAR SAFETY GLASSES. Everyday
eyeglasses have only impact-resistant lenses; they
are NOT safety glasses.

12. PROTECT YOUR LUNGS. Wear a face mask or
dust mask if operation is dusty.

13. PROTECT YOUR HEARING. Wear hearing
protection during extended periods of operation.

14. DON'T ABUSE CORD. Never carry tool by cord or
yank it to disconnect from receptacle. Keep cord
from heat, oil and sharp edges.

15. SECURE WORK. Use clamps or a vise to hold
work. Both hands are needed to operate the tool.

16. DON'T OVERREACH. Keep proper footing and
balance at all times. Do not use on a ladder or
unstable support.

17. MAINTAIN TOOLS WITH CARE. Keep tools sharp
at all times, and clean for best and safest
performance. Follow instructions for lubricating
and changing accessories.

18. DISCONNECT TOOLS. When not in use, before
servicing, or when changing attachments, blades,
bits, cutters, etc., all tools should be disconnected
from power supply.

19. REMOVE CHUCK KEY. Form habit of checking to
see that chuck key is removed from chuck before
turning tool on.

20. AVOID ACCIDENTAL STARTING. Don't carry
plugged-in tools with finger on switch. Be sure
switch is off when plugging in.

RULES FOR SAFE OPERATION (Continued)

21. 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.

22. OUTDOOR USE EXTENSION CORDS. When
tool is used outdoors, use only extension cords
suitable for use outdoors. Outdoor approved cords
are marked with the suffix W-A, for example ­SJTW-A or SJOW-A.

23. KEEP BITS CLEAN AND SHARP. Sharp bits
minimize stalling and kickback.

24. KEEP HANDS AWAY FROM DRILLING AREA.
Keep hands away from bits. Do not reach
underneath work while bit is rotating. Do not attempt
to remove material while bit is rotating.

25. NEVER USE IN AN EXPLOSIVE ATMOSPHERE.
Normal sparking of the motor could ignite fumes.

26. INSPECT TOOL CORDS PERIODICALLY and if
damaged, have repaired at your nearest Sears
Repair Center. Stay constantly aware of cord
location.

27. INSPECT EXTENSION CORDS PERIODICALLY
and replace if damaged.

28. KEEP HANDLES DRY, CLEAN, AND FREE
FROM OIL AND GREASE. Always use a clean
cloth when cleaning. Never use brake fluids,
gasoline, petroleum-based products or any strong
solvents to clean your tool.

29. STAY ALERT. Watch what you are doing and use
common sense. Do not operate tool when you are
tired. Do not rush.

30. CHECK DAMAGED PARTS. Before further use of
the tool, a guard or other part that is damaged
should be carefully checked to determine that it will
operate properly and perform its intended function.
Check for alignment of moving parts, binding of
moving parts, breakage of parts, mounting, and
any other conditions that may affect its operation.
A guard or other part that is damaged should be
properly repaired or replaced by an authorized
service center unless indicated elsewhere in this
instruction manual.

31. DO NOT USE TOOL IF SWITCH DOES NOT
TURN IT ON AND OFF. Have defective switches
replaced by an authorized service center.

32. DRILLING INTO ELECTRICAL WIRING IN

WALLS CAN CAUSE DRILL BIT AND CHUCK
TO BECOME ELECTRICALLY LIVE. Do not touch

the chuck or metal housing when drilling into a
wall; grasp only the insulated handle(s) provided
on the tool.

33. INSPECT FOR and remove all nails from lumber
before drilling.

34. DRUGS, ALCOHOL, MEDICATION. Do not
operate tool while under the influence of drugs,
alcohol, or any medication.

35. WHEN SERVICING USE ONLY IDENTICAL

CRAFTSMAN REPLACEMENT PARTS.

36. POLARIZED PLUGS. To reduce the risk of electric
shock, this tool has a polarized plug (one blade is
wider than the other). This plug will fit in a polarized
outlet only one way. If the plug does not fit fully in
the outlet, reverse the plug. If it still does not fit,
contact a qualified electrician to install the proper
outlet. Do not change the plug in any way.

37. SAVE THESE INSTRUCTIONS. Review them
frequently and use them to instruct others who
may use this tool. If you loan someone this tool,
loan them these instructions also.

WARNING:

Some dust created by power sanding, sawing,
grinding, drilling, and other construction activities
contains chemicals known to cause cancer, birth
defects or other reproductive harm. Some examples
of these chemicals are:

• lead from lead-based paints,

• crystalline silica from bricks and cement and other
masonry products, and

• arsenic and chromium from chemically-treated
lumber.

Your risk from these exposures varies, depending on
how often you do this type of work. To reduce your
exposure to these chemicals: work in a well ventilated
area, and work with approved safety equipment,
such as those dust masks that are specially designed
to filter out microscopic particles.

OPERATION

WARNING:

Always wear safety goggles or safety glasses with side
shields when operating your hammer drill. Failure to do so
could result in dust, shavings, loose particles or foreign
objects being thrown into your eyes, causing possible
serious injury.

ELECTRICAL CONNECTION

Your hammer drill has a precision built electric motor. It
should be connected to a power supply that is 120 volts,
60 Hz, AC only (normal household current). Do not
operate this tool on direct current (DC). A voltage drop of
more than 10 percent will cause a loss of power and the
motor will overheat. If your tool does not operate when
plugged into an outlet, double-check the power supply.

KNOW YOUR HAMMER DRILL

Before attempting to use your hammer drill, familiarize
yourself with all operating features and safety requirements.

See Figure 1.

WARNING:

If any parts are missing, do not operate your hammer drill
until the missing parts are replaced. Failure to do so could
result in possible serious personal injury.

WARNING:

Do not allow familiarity with your hammer drill to make you
careless. Remember that a careless fraction of a second
is sufficient to inflict severe injury.
