Read and understand all instructions. Failure to follow all instructions
listed below, may result in electric shock, fire and/or serious personal injury.
SAVE THESE INSTRUCTIONS
Work Area
Keep your work area clean and well lit.
Cluttered benches and dark areas invite
accidents.
Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gases, or dust. Power
tools create sparks which may ignite the
dust or fumes.
Keep by-standers, children, and visitors
away while operating a power tool.
Distractions can cause you to lose control.
Electrical Safety
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. Before
plugging in the tool, be certain the outlet
voltage supplied is within the voltage
marked on the nameplate. Do not use "AC
only" rated tools with a DC power supply.
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. If operating the power tool in
damp locations is unavoidable, a Ground
Fault Circuit Interrupter must be used to
supply the power to your tool. Electrician's
rubber gloves and footwear will further
enhance your personal safety.
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 carry 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.
When operating a power tool outside,
use an outdoor extension cord marked
"W-A" or "W." These cords are rated for
outdoor use and reduce the risk of electric
shock. Refer to "Recommended sizes of
Extension Cords" in the Accessory section
of this manual.
Personal Safety
Stay alert, watch what you are doing and
use common sense when operating a
power tool. Do not use tool while tired or
under the influence of drugs, alcohol, or
medication. A moment of inattention while
operating power tools may result in serious
personal injury.
Dress properly. Do not wear loose
clothing or jewelry. Contain long hair.
Keep your hair, clothing, and gloves
away from moving parts. Loose clothes,
jewelry, or tong hair can be caught in
moving parts. Keep handles dry, clean and
free from oil and grease.
Avoid accidental starting. Be sure switch
is "OFF" before plugging in. Carrying
tools with your finger on the switch or
plugging in tools that have the switch "ON"
invites accidents.
Remove adjusting keys or wrenches
before turning the tool "ON". A wrench or
a key that is left attached to a rotating part
of the tool may result in personal injury.
Do not overreach. Keep proper footing
and balance at all times. Proper footing
and balance enables better control of the
tool in unexpected situations.
Use safety equipment. Always wear eye
protection. Dust mask, non-skid safety
shoes, hard hat, or hearing protection must
be used for appropriate conditions.
Tool Use and Care
Use clamps or other practical way to
secure and support the workpiece to a
stable platform. Holding the work by hand
or against your body is unstable and may
lead to loss of control.
Do not force tool. Use the correct tool for
your application. The correct tool will do
the job better and safer at the rate for which
it is designed.
Do not use tool if switch does not turn it
"ON" or "OFF". Any tool that cannot be
controlled with the switch is dangerous and
must be repaired.
Disconnect the plug from the power
source before making any adjustments,
changing accessories, or storing the
tool. Such preventive safety measures
reduce the risk of starting the tool
accidentally. Store idle tools out of reach
of children and other untrained persons.
Tools are dangerous in the hands of
untrained users.
Maintain tools with care. Keep cutting
tools sharp and clean. Properly
maintained tools, with sharp cutting edges
are less likely to bind and are easier to
control. Any alteration or modification is a
misuse and may result in a dangerous
condition.
Check for misaUgnment or binding of
moving parts, breakage of parts, and any
other condition that may affect the tools
operation. If damaged, have the tool
serviced before using. Many accidents are
caused by poorly maintained tools. Develop
a periodic maintenance schedule for your
tool.
Use only accessories that are
recommended by the manufacturer for
your model. Accessories that may be
suitable for one tool, may become
hazardous when used on another tool.
Service
Tool service must be performed only by
qualified repair personnel. Service or
maintenance performed by unqualified
personnel could result in a risk of injury. For
example: internal wires may be misplaced
or pinched, safety guard return springs may
be improperly mounted.
When servicing a tool, use only identical
replacement parts. Follow instructions in
the Maintenance section of this manual.
Use of unauthorized parts or failure to
follow Maintenance Instructions may create
a risk of electric shock or injury. Certain
cleaning agents such as gasoline, carbon
tetrachloride, ammonia, etc. may damage
plastic parts.
Accessories must be rated for at least
the speed recommended on the tool
warning label. Wheels and other
accessories running over rated speed can
fly apart and cause injury.
Hold tool by insulated gripping surfaces
when performing an operation where the
cutting tool may contact hidden wiring or
its own cord. Contact with a "live" wire will
make exposed metal parts of the tool "live"
and shock the operator. If cutting into
existing walls or other blind areas where
electrical wiring may exist is unavoidable,
disconnect all fuses or circuit breakers
feeding this worksite.
The following warning is intended for flex
shaft tools and accessories: Do not
operate the flexible shaft with a sharp
bend. Over bending the shaft can generate
excessive heat on the jacket or hand piece.
The recommended minimum is 6" radius.
Always disconnect the power cord from
the power source before making any
adjustments or attaching any
accessories. You may unexpectedly cause
the tool to start leading to serious persohal
injury.
Be aware of the switch location, when
placing the tool down or when picking
the tool up. You may accidentally activate
the switch.
The following warning is intended for flex
shaft tools and accessories: Always hold
the hand piece firmly in your hands
during the start-up. The reaction torque of
the motor, as it accelerates to full speed,
can cause the shaft to twist.
Always hold the tool with two hands
during start-up. The reaction torque of the
motor can cause the tool to twist.
Always wear safety goggles and dust
mask. Use only in well ventilated area.
Using personal safety devices and working
in safe environment reduces risk of injury.
After changing the bits or making any
adjustments, make sure the collet nut
and any other adjustment devices are
securely tightened. Loose adjustment
device can unexpectedly shift, causing loss
of control, loose rotating components will
be violently thrown.
Do not reach in the area of the spinning
bit. The proximity of the spinning bit to your
hand may not always be obvious.
Allow brushes to run at operating speed
for at least one minute before using
wheel. During this time no one is to stand
in front or in line with the brush. Loose
bristles or wires will be discharged during
the run-in time.
Wire and bristle brushes must never be
operated at speeds greater than
15,000/min. Direct the discharge of the
spinning wire brush away from you.
Small particles and tiny wire fragments may
be discharged at high velocity during the
"cleaning" action with these brushes and
may become imbedded in your skin.
Bristles or wires will be discharged from the
brush at high speeds.
Wear protective gloves and face shield
with wire or bristle brushes. Apply wire
or bristle brushes lightly to the work as
only the tips of the wire/bristles do the
work. "Heavy" pressure on bristles will
cause the wire or bristle to become
overstressed, resulting in a wiping action
and will cause the bristles/wire to be
discharged.
Carefully handle both the tool and
individual grinding wheels to avoid
chipping or cracking. Install a new wheel
if tool is dropped while grinding. Do not
use a wheel that may be damaged.
Fragments from a wheel that bursts during
operation will fly away at great velocity
possibly striking you or bystanders.
Never use dull or damaged bits. Sharp
bits must be handled with care.
Damaged bits -can snap during use. Dull bits
require more force to push the tool,
possibly causing the bit to break.
Use clamps to support workpiece
whenever practical. Never hold a small
workpiece in one hand and the tool in the
other hand while in use. Allow for
sufficient space, at least 6", between
your hand and the spinning bit. Round
material such as dowel rods, pipes Or
tubing have a tendency to rol! while being
cut, and may cause the bit to "bite" or jump
toward you. Clamping a small workpiece
allows you to use both hands to control the
tool.
Inspect your workpiece before cutting.
When cutting irregularly shaped
workpieces, plan your work so it will not
slip and pinch the bit and be torn from
your hand. For example, if carving wood,
make sure there are no nails or foreign
objects in the workpiece. Nails or foreign
objects can cause the bit to jump.
Never start the tool when the bit is
engaged in the material. The bit cutting
edge may grab the material causing loss of
control of the cutter.
Avoid bouncing and snagging the wheel,
especially when working corners, sharp
edges etc. This can cause loss of control
and kick-back.
The direction of feed with the bit into the
material when carving, routing or cutting
is very important. Always feed the bit
into the material in the same direction as
the cutting edge is exiting from the
material (which is the same direction as
the chips are thrown). Feeding the tool in
the wrong direction, causes the cutting
edge of the bit to climb out of the work and
pull the tool in the direction of this feed.
If the workpiece or bit becomes jammed
or bogged down, turn the tool "OFF" by
the switch. Wait for all moving parts to
stop and unplug the tool, then work to
free the jammed material. If the switch to
the tool is left "ON" the tool could restart
unexpectedly causing serious perspnal
injury.
Do not leave a running tool unattended,
turn power off. Only when tool comes to a
complete stop it is safe to put it down.
Do not grind or sand near flammable
materials. Sparks from the wheel could
ignite these materials.
Do not touch the bit or collet after use.
After use the bit and collet are too hot to be
touched by bare hands.
Regularly clean the tool's air vents by
compressed air. Excessive accumulation
of powdered metal inside the motor housing
may cause electrical failures.
Do not allow familiarity gained from
frequent use of your rotary tool to
become commonplace. Always remember
that a careless fraction of a second is
sufficient to inflict severe injury.
Do not alter or misuse tool. Any alteration
or modification is a misuse and may result
in serious personal injury.
This product is not intended for use as a
dental drill, in human or veterinary
medical applications. Serious personal
injury may result.
When using the steel saws, cutoff
wheels, high speed cutters or tungsten
carbide cutters, always have the work
securely clamped. Never attempt to hold
the work with one hand while using any
of these accessories. The reason is that
these wheels will grab if they become
slightly canted in the groove, and can kick-
back causing loss of control resulting in
serious injury. Your second hand should be
used to steady and guide the hand holding
the tool. When a cutoff wheel grabs, the
wheel itself usually breaks. When the steel
saw, high speed cutters or tungsten carbide
cutter grab, it may jump from the groove
and you could lose control of the tool.
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 chemicaUy-
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 ventitated area,
and work with approved safety equipment,
such as those dust masks that are specially
designed to filter out microscopic particles.

COLLET -- To loosen, first press shaft lock
button and rotate the shaft by hand until the
lock engages the shaft preventing further
rotation.
Do not engage lock while
the Rotary Tool is running.
With the shaft lock engaged use the collet
wrench to loosen the collet nut if necessary.
Change accessories by inserting the new
one into the collet as far as possible to
minimize runout and unbalance. With the
shaft lock engaged, finger tighten the collet
nut until the accessory shank is gripped by
the collet. Avoid excessive tightening of the
collet nut. The collet system is a superior
method of securing accessories.
COLLETS -- Two different size collets (see
illustration), to accommodate different shank
sizes, are available for your Rotary Tool. To
install a different collet, remove the collet nut
and remove the old collet. Insert the
unslotted end of the collet in the hole in the
end of the tool shaft. Replace collet nut on
the shaft. Always use the collet which
matches the shank size of the accessory
you plan to use. Never force a larger
diameter shank into a collet.
BALANCING ACCESSORIES -- For
precision work, it is important that all
accessories be in good balance (much the
same as the tires on your automobile). To
true up or balance an accessory, slightly
loosen collet nut and give the accessory Or

collet a 1/4 turn. Retighten collet nut and run
the Rotary Tool. You should be able to tell
by the sound and feel if your accessory is
running in balance. Continue adjusting in this
fashion until best balance is achieved. To
maintain balance on abrasive wheel points,
before each use, with the wheel point
secured in the collet, turn on the Rotary Tool
and run the Dressing Stone lightly against
the revolving wheel point. This removes high
spots and trues up the wheel point for good
balance.
The hanger is provided for the use of
hanging your tool while using the flex-shaft
or for storage. If you do not use the hanger,
remove it from the tool and snap it back into
place underneath the cord so it will be out of
the way while the tool is in use.
Remember, your new Craftsman Rotary Tool
is the finest power tool of its kind. But its
performance is only as good as the
accessories with which it is used.
We recommend only Craftsman
accessories be used. Use of any other
accessories may create a hazard. We hope
you'll enjoy many years of trouble free
pleasure from your Sears Craftsman Rotary
Power Toot.
lO
KEYLESS CHUCK -- The keyless chuck
holds various accessories with shank sizes
1/32" to !/8" and is intended for light duty
accessories such as drill bits, sanding
drums, polishing accessories, wire and
bristle brushes and cut-off wheels. The
keyless chuck allows you to change
accessories frequently, quickly and easily.
There are some applications which can
generate high forces on the bit or if you are
unable to generate finger tightening pressure
sufficient to secure the bit you must use the
supplied wrench to assist in securing the bit.
Attaching the Keyless Chuck and
Accessory Bit
Read and understand the
manual for use of the
keyless chuck with the tool. Insert and
securely tighten the shank of the
accessory well within the jaws of the
chuck. If an accessory is not properly
gripped within the jaws of a chuck it may
loosen and fly out during use possibly
striking you or bystanders.
To replace or attach the keyless chuck
accessory to your MultiPro rotary tool,
unplug the tool and engage the shaft lock
button then remove the collet and collet nut.
Thread the keyless chuck on the end of the
shaft. Engage the shaft lock button again,
insert the accessory shank into the chuck
and finger tighten until the shank is secure.
For small size drill bits, close the chuck to
the point where the bit will just fit in; then
tighten securely. This helps center the bit in
the keyless chuck correctly. In some high
force applications such as removing metal,
tile cutting or routing, the bit (tungsten
carbide cutters, high speed cutters, router
bits or tile cutters) and chuck will become
hot if overloaded for extended periods of
time. Overloading the chuck may cause the
bit to loosen and slip. It is recommended
that in these types of applications that the
bit be secured in the chuck with the supplied
wrench and work in intervals to allow cooling
of the bit and chuck. If the bit slips the tool
will begin to vibrate excessively, this is an
indication that you should shut the tool off,
re-position and tighten the bit then allow the
tool to run no-load for a few minutes to cool.
The chuck should be cleaned occasionally to
keep it functioning properly. Simply remove
the chuck from the tool and gently tap the
tip of the chuck on a fat surface to remove
any loose debris. In some applications the
keyless chuck may tighten up during use. If
this occurs, gently loosen using the wrench
included in your rotary tool kit.

The Rotary Tool is a handful of high-speed
power. It serves as a carver, grinder,
polisher, sander, cutter, power brush, drill
and more.
The Rotary Tool has a small, powerful
electric motor, is comfortable in the hand,
and is made to accept a large variety of
accessories including abrasive wheels, drill
bits, wire brushes, polishers, engraving
cutters, router bits, and cutting wheels.
Accessories come in a variety of shapes and
permit you to do a number of different jobs.
As you become familiar with the range of
accessories and their uses, you will learn just
how versatile the Rotary Tool is. You'll see
dozens of uses you hadn't thought of before.
The real secret of the Rotary Tool is its
speed. To understand the advantages of its
high speed, you have to know that the
standard portable electric drill runs at
speeds up to 2,800 revolutions per minute.
The Rotary Tool operates at speeds up to
35,000 revolutions per minute. The typical
electric drill is a low-speed, high torque tool;
the Rotary Tool is just the opposite - a high-
speed, low torque tool. The chief difference
to the user is that in the high speed tools,
the speed combined with the accessory
mounted in the collet does the work. You
don't apply pressure to the tool, but simply
hold and guide it. In the low speed tools, you
not only guide the tool, but also apply
pressure to it, as you do, for example, when
drilling a hole.
It is this high speed, along with its compact
size and wide variety of special accessories,
that makes the Rotary Tool different from
other power tools. The speed enables it to
do jobs low speed tools cannot do, such as
cutting hardened steel, engraving glad, etc.
Getting the most out of your Rotary Tool is a
matter of learning how to let this speed work
for you.

USING THE ROTARY POWER TOOL
The first step in learning to use the Rotary
Tool is to get the "feel" of it. Hold it in your
hand and feel its weight and balance. Feel
the taper of the housing. This taper permits
the Rotary Tool to be grasped much like a
pen or pencil. The Variable Speed tool has a
unique comfort grip on the nose and back
seating, which allows the user added
comfort and control during use. You can feel
the difference!
When you turn on the tool for the first time,
hold it away from your face. Accessories can
be damaged during handling, and can fly
apart as they come up to speed. This is not
common, but it may happen.
Practice on scrap materials first to see how
the Rotary Tool cuts. Keep in mind that the
work is done by the speed of the tool and by
the accessory in the collet. You should not
! lean on or push the tool into the work.
Instead, lower the spinning accessory lightly
to the work and allow it to touch the point at
which you want cutting (or sanding or
etching, etc.) to begin. Concentrate on
guiding the tool over the work using very
little pressure from your hand. Allow the
accessory to do the work.
Usually, it is best to make a series of passes
with the tool rather than attempt to do all the
work in one pass. To make a cut, for
example, pass the tool back and forth over
the work, much as you would a small paint
brush. Cut a little material on each pass until
you reach the desired depth. For most work,
the gentle touch is best. With it, you have
the best control, are tess likely to make
errors, and will get the most efficient work
out of the accessory.
For best control in close work, grip the Rotary
Tool like a pencil between your thumb and
forefinger.
_ henever you hold the tool, be careful
This blocks the air flow and causes the motor to overheat.
The "handgrip" method of holding the tool is
used for operations such as grinding a flat
surface or using cutoff wheels.
not to cover the air vents with your hand.

OPERATJN G SPEEDS
Set the speed indicator to fit the job; to achieve
the best job results when working with different
materials, the speed of the Rotary Tool shoukt
be regulated.
Models 610960 & 610950
Rotary Tools have an
integral speed control and an external
speed control should never be used with
these tools.
To select the right speed for each job, use a
practice piece of material. Vary' speed to find
the best speed for the accessory you are using
and the job to be done.
NOTE: Speed is affected by voltage
changes. A reduced incoming voltage will
slow the RPM of the tool, especially at the
lowest setting. If your tool appears to be
running slowly increase the speed setting
accordingly.
There are three basic types of Rotary Tools:
single speed, two-speed and variable speed
models.
• Single speed has one ON-OFF switch,
When the switch is on, the toot runs at
35,000 RPM.
• On the two-speed-model, there is a LO and
HI switch. When the switch indicator is on
the low setting, the tool runs at about 15,000
RPM. When the switch indicator is on the
high setting, the tool runs at about 35,000
RPM.
• On the variable speed model, there are
switch setting indicators marked with a
line. Slide to the number on the housing to
select the operating speed needed from
5,000 - 35,000 RPM.
You can refer to the charts on pages ?6 & 27'
to determine the proper speea, based on the
material being worked and the t_!_e o; t': _tb_ro:_
other accessory being used. These charts
enable you to select both the correct acces-
sory and the optimum speed at a glance.
If you have a single-speed or two-sF-ee'd
model, you will be able to use many
accessories to do a wide assortment of jobs.
For the majority of applications, all models of
the Rotary Tool should be used at top speed.
NEEDS FOR SLOWER SPEEDS
Certain materials, however, (some plastics, for
example) require a relatively slow speed
because at high speed the friction of the
accessory generates heat and causes the '
plastic to melt.
S_ow speeds (15,000 RPM or less) usually are
best for polishing operations employing the felt
polishing accessories. They may also be best
for working on delicate projects as "eggery"
work. delicate wood carving and fragile model
parts. All brushing applications require lower
speeds to avoid wire discharge from the
holder.
Higher speeds are better for carving, cutting,
routing, shaping, cutting dadoes or rabbets in
wood.
Hardwoods, metals and glass require high
speed operation, and drilling should also be
done at high speeds.
The speed of the Rotary Tool is controlled
by setting this indicator on the housing.

"Model610950Wir::Brusil Seiting.
The point to remem.ber is this: You can do the
great majority of work with the single speed at
its regular speed of 35.000 RPM. But for
certain materials and types of work, you need
slower speeds -- which is the reason the
variable speed models were developed.
To aid you in determining the optimum
operational speed for different materials and
different accessories, we have constructed
table that appears on pages 26 & 27. By
referring to this table, you can determine the
recommended speeds for each type of
14
accessory. Look this table over and become
familiar with it.
Ultimately, the best way to determine the
correct speed for work on any material is to
practice for a few minutes on a piece of
scrap, even after referring to the chart. You
can quickly learn that a slower or faster
speed is more effective just by observing
what happens as you make a pass or two at
different speeds. When working with plastic,
for example, start at a slow rate of speed
and increase the speed until you observe
that the plastic is melting at the point of
contact. Then reduce the speed slightly to
get the optimum working speed.
Some rules of thumb in regard to speed:
1. Plastic and materials that melt at low
i temperatures should be cut at low
;speeds.
2. Polishing, buffing and cleaning with a wire
brush must be done at speeds not greater
than 15,000 RPM to prevent damage to
the brush.
3. Wood should be cut at high speed.
4. Iron or steel should be cut at high speed if
using tungsten carbide accessory, but at
slower speeds if using high speed steel
cutters. If a high speed steel cutter starts
to chatter -- this normally means it is
running too slow.
5. Aluminum, copper alloys, lead alloys, zinc
alloys and tin may be cut at various
speeds, depending on the type of cutting
being done. Use paraffin or other suitable
lubricant on the cutter to prevent the cut
material from adhering to the cutter teeth.
Increasing the pressure on the tool is not the
answer when it is not cutting as you think it
should. Perhaps you should be using a
different cutter, and perhaps an adjustment
in speed would solve the problem. Leaning
on the tool does not help. The correct speed
will make using the rotary tool effortless.
BRUSHING PRESSURE
1. Remember, the tips of a wire brush do the
work. Operate the brush with the lightest
pressure so only the tips of the wire come in
contact with the work.
2. If heavier pressures are used, the wires
will be overstressed, resulting in a wiping
action; and if this is continued, the life of the

brush will be shortened due to wire fatigue.
3. Apply the brush to the work in such a way
that as much of the brush face as possible is
in full contact with the work. Applying the
side or edge of the brush to the work wil!
result in wire breakage and shortened brush
life.

cap. This could cause disengagement of
center core from handpiece. If tool stops
when shaft is bent, center core may be
lodged in driver cap. Loosen shaft and
remove core from driver cap. Then screw
flexible shaft onto rotary tool housing again.
Flex-Shaft Collet Assembly
The collet assembly consists of a co!let nut
and collet. To change bits use the wrench
and a bit. Insert the shank portion of any bit
(1/8" shank recommended) through the
opening in the flex-shaft hand piece to lock
the shaft. With the shaft secured, use the
wrench to loosen or tighten the collet nut as
shown in Figure 4. With the collet nut loose,
insert an accessory or bit as deeply as
possible to avoid wobble during use.
Retighten the collet nut.
Collet Removal and Replacement
Four different size collets to accommodate
different shank sizes, are available for your
flex-shaft. To install a different collet, remove
the collet nut and remove the old collet.
Insert the unslotted end of the collet in the
hole in the end of the flex-shaft. Replace
collet nut on the shaft. Always use the
collet which matches the shank size of
the accessory you plan to use,
Never force a larger diameter shank into a
collet.

Flexible Shaft Lubrication
The flexible shaft should be lubricated after
every 25-30 hours of use. To lubricate,
unscrew the flexible shaft assembly from the
motor housing. Pull the center core out of
the flexible shaft assembly. Wipe a very thin
film of a good quality, high temperature
grease on to the center core.
