gNTRODUCTION
DOUBLE INSULATION
is a concept in safety, in
etectric 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 the internal metal motor
components
with protecting
insulation..
IMPORl'ANT_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.
RULES
FOR SAFE OPERATION
Your Craftsman 4-inch Dustless Belt Sander is suitable
for coarse, medium and fine sanding of wood, metals,
plastics and other materials. It is ideal when used for
smoothing rough boards, chamfering, rounding edges
and many other general sanding applications. It is ideal
for refinishing
large pieces of furniture,
stairs and
other large surfaces. Its balanced design makes it easy
to use.
The built-in dust collection system will remove most of
the sanding dust from the work and eliminate the dust
in the air -- usually associated
with power sanding°
SWITCH
A trigger switch controls operation of the Sander',
The trigger switch can be locked on for continuous
operatiom
To lock, pull trigger, press lock button
inward, and release trigger, Pull trigger and release
to stop°
1. KNOW YOUR POWER TOOL _ Read owner's manual carefulty,_ Learn its applications and limitations
as well as the specific potential hazards peculiar to this tool.
2, GROUND ALL TOOLS -- UNLESS DOUBLE-INSULATED.
If tool is equipped
with three-prong
plug, it should be plugged into a three-hole electrical receptacle, tf adapter is used to accommodate
two-prong
receptacle,
the adapter wire must be attached to a known ground. (Usually the screw
securing receptacle cover plate)_ Never remove third prong.
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 toot in damp or wet locations or expose to
r&in. Keep work area well tit.
6 KEEP CHILDREN AWAY. Al! visitors should be kept safe distance from work area.
7. STORE IDLE TOOLS. When not in use, tools should be stored ;n dry, high or-locked-up place_out
of

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 toot..
10 WEAR PROPER APPAREL. No loose clothing or jewetry to get caught in moving parts_ Rubber gloves
and footwear are recommended
when working outdoors,
11 USE SAFETY GLASSES with most tools. Also face or dust mask if cutting operation is dusty_
12 DON'T ABUSE CORD. Never carry toot by cord or yank it to disconnect
from receptacle. Keep cord
from heat, oil and sharp edges°
!3. SECURE WORK. Use clamps or a vise to hold work it's safer than using your hand and it frees both

OPERATION
PREPARING
FOR OPERATION
Your Sander is equipped with its own built-in auxiliary handle
located at the front of the unit, This handle allows for twohand use which wilt aid in maintaining
complete control and
keeping sanding area level with work piece (See Fig, 1),
Selecting the correct size and type sanding belt is an extremely
important
step in achieving
a high quality
sanded finish,.
Aluminum oxide silicone carbide and other synthetic abrasives
are best for power sanding.
In general, coarse grit will remove the most material and finer
grit will produce best finish in all sanding operations,
The
condition of the surface to be sanded will determine which grit
belt will do the job, If the surface is rough, start with a coarse
grit belt sanding until surface is uniform., Medium grit belt may
then be used to remove scratches left by the coarser belt and
finer grit belt used for finishing
of the surface. Always continue sanding with each grit belt until surface is uniform°

INSTALLING
AND ADJUSTING
SANDING
BELT
Be sure power cord is disconnected from power supply.
1. Release tension on belt by pushing the front
pulley
squarely against the top or edge of workbench (See Fig. 2).
When the pulley is pushed back it will lock in that position,
allowing slack in the belt so it can be removed. NOTE: Idler
pulley rubbing housing when in the released position,
without sandpaper, does not damage toot operation. The
sanding belt, when assembled,
will not allow pulley to
project as far.
2, To install new belt, place belt over both pulleys, making
sure that arrow on inside of belt is pointing in the direction
of rotation which is clockwise when looking into open side
of sander.
3,. Make sure fingers are not in a position to get mashed. Pull
hard on lever (A) until pulley is released and tension
is
applied to bett. The lever will move freely at first and then
become harder to pull
4,, To adjust belt, connect sander to power supply,, Stand
sander on end as illustrated (See Fig,, 3), Pull switch trigger
and release immediately
while observing tracking of belt.
5o tf belt runs outward, turn tracking screw (B) clockwise and
counterclockwise
if belt runs inward. This should be done
until you are sure belt will not come in contact with rub
strip,
6 Start sander and fine adjust the tracking screw (B) until belt
stabilizes. When correctly adjusted, the outer edge of the
belt will be even with outer edge of wear plate,
Note: Belt life will be increased if a few seconds are spent
adjusting
the belt tracking properly°
TO OPERATE
Clamp or otherwise secure the work to prevent it moving under
the Sander., With Sander off work, press the trigger switch and
when the motor reaches its maximum speed, lower the Sander
on the work with a slight forward motion
Using the main
handle to control the Sander and the front handle only to guide
it, move it slowly over the work, Allowing the Sander to remain
in one place will result in an uneven surface, The Sander was
designed to provide the proper weight on the sand belt and
extra pressure wil! only result in uneven work, stow cutting
from slow belt speed, clogged belts and possible motor burnouL
Use the proper belt when heavy cutting is desired, not heavy
pressure. The importance of this cannot be over-emphasized,
the weight has been built into the tool to give the most efficient pressure at the proper location.

GENERAL
DUST PICK-UP The dust bag assembly
is slipped
with a twisting motion over the blower exhaust.. The
bag may be turned toward the side as required for
the operator's convenience
Although the bag is of
ample size it should
be emptied
frequently
to
maintain the pick-up efficiency.
The bag is emptied
by grasping the fitting and twisting it off the blower
exhaust. Opening the zipper at the bottom of the bag
will allow complete cleaning.. When sanding, some
dust, paper, belt threads and etc. may collect on the
blower and reduce the efficiency of the blower.. To
clean blower (See Fig. 5) remove screws (A) and
blower
housing
coupling
(B)_. Replace
blower
housing coupling (B) and screws (A).. Do not over
tighten screws (A)o
All 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.
EXTENSION
Only the parts shown outside Section A on page six
are intended to be replaced by the customer,. Parts
listed in Section A represent an important part of the
double insulation
system and should be serviced
only by a qualified service technician°
Avoid using solvents when cleaning
plastic parts.
Most plastics
are susceptible
to various types of
commercial
solvents and may be damaged by their
use. Use clean cloths to remove dirt, carbon dust,
etc.
When electric tools are used on fiberglass
boats,
sports cars, etc., it has been found that they are
subject to accelerated wear and possible premature
failure, as the fiberglass
chips and grindings
are
highly
abrasive
to
bearings,
brushes,
commutator,etc.
Consequently
it is not recommended
that this tool be used for continuous
production
work on any fiberglass material. During any use on
fiberglass it is extremely important
that the tool is
cleaned frequently
by blowing with an air jet°
CORDS
The use of any extension cord wil! cause some loss
of power° To keep the toss to a minimum
and to
prevent tool overheating,
follow the recommended
cord sizes on the chart at right. Extension cords are
available at Sears Catalog Order or Retail Stores.,
