RULES FOR SAFE OPERATION

DOUBLE INSULATION is a safety concept 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:

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.

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, 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 the
tool's moving parts and cause personal injury.
Rubber gloves and non-skid footwear are

12. PROTECT YOUR LUNGS. Wear a face 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.

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

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. NEVER USE THIS OR ANY POWER SANDER
FOR WET SANDING. Failure to comply can result
in electrical shock causing serious injury or worse.

24. KEEP HANDS AWAY FROM SANDING AREA.

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. INSPECT FOR and remove all nails from lumber
before sanding.

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

34. WHEN SERVICING USE ONLY IDENTICAL

CRAFTSMAN REPLACEMENT PARTS.

35. 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.

36. 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.
