ELECTRICAL

Double insulated tools are equipped with 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 a polarized outlet.
Do not change the plug in any way. Double insulation [] eliminates the need for the three-wire
grounded power cord and grounded power supply
system.
• Avoid body contact with grounded surfaces such
as pipes, radiators, ranges, and refrigerators.
There is an increased risk of electric shock if your
body is grounded.
• Don't expose power tools to rain or wet conditions. Water entering a power tool will increase the
risk of electric shock.
• Do not abuse the cord. Never use the cord to
carw the tools or pull the plug from an outlet.
Keep cord away from heat, oil, sharp edges, or
moving parts. Replace damaged cords Immediately, Damaged cords increase the risk of electric
shock.

•

Use safety equipment.
Alwayswear
eye protection. Dust mask, nonskid safety shoes, hard hat, or
hearing protection must be used for appropriate
conditions,
Do not wear loose clothing or jewelw. Contain
long hair. Loose clothes, Jewelry, or long hair can be
drawn into air vents.
Do not use on a ladder or unstable support. Stable
footing on a solid surface enables better control of the
tool in unexpected situations.

•

DOUBLE INSULATION

EXTENSION

Double insulation is a concapt 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 the internal metal motor components with
protecting insulation, Double insulated tools do not need
to be grounded,

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.

Important: Servicing of a tool with double insulation
requires extreme care and knowredge of the system and
should be performed only by a qualified service
technician. For service, we suggest you return the tool
to your nearest authorized service center for repair,
When servicing, use only identical Craftsman
replacement ports.

length. When working outdoors, use an extension cord
that is suitable for outdoor use, This type of cord is
designated with '%'A" on the cord's jacket.

A wire gage size (A,W,G,) of at least 14 is
recommended for an extension cord 50 feet or less in

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

ELECTRICAL

CORDS

CAUTION: Keep extension cords clear of the
working area. While you are working with a power
tool, position the cord so that it will not get caught

SELECTING

SANDING

BELTS

Selecting the correct size and type of sanding belt is an
important step in achieving a high quality sanded finish.
Aluminum oxide, silicon carbide, and other synthetic
abrasives are best for power sanding.
in general, when sanding, coarse grit removes the most
material and fine grit produces the best finish. The
condition of the surface to be sanded determines which
grit wilt do the best job. If the surface is rough, start with
a coarse grit and send until the surface is uniform, Then
use medium grit to remove scratches left by the coarser
grit. Finally, use finer grit for finishing the surface.
Always continue sanding with each grit until the surface
is uniform,

WARNING:
The belt sander should never be
connected to a power supply when you are
assembling parts, mak)ng adjustments, cleaning,
performing maintenance, or when the tool is not in
use. Disconnecting the tool prevents accidental
starting that could cause serious Iniury.

Electric tools used on fiberglass material, wallboard,
spackling compounds, or plaster are subject to
accelerated wear and possible premature failure
because the fiberglass chips and grindings are highly
abrasive to bearings, brushes, commutators, etc.
Consequently, we do not recommend using this tool for
extended work on these types of materials. However. iI
you do work with any of these materials, it is extremely
important to clean the tool using compressed air.
WARNING:
Always wear safety goggles or safety
glasses with side shields during power tool
operation or when blowing dust. if operation is
dusty, also wear a dust mask. Failure to do so
could result Jnpossible serious injury.

GENERAL

repaired or replaced by the customer. All other parts are
an important part of the double insulation system and
should be serviced only by a qualified Sears service
technici_,n.

LUBRICATION
All the bearings in this tool are lubricated with a
sufficient amount of high grade lubricant for the life of
the tool 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
commercial solvents and may be damaged by their use.
Use clean cloths to remove dirt, carbon dust, etc.
