Safety Instructions
Before using your Foredom®power tool,
please read safety instructions.
They are
for your protection and should always be
followed to reduce the risk of personal
injury or damage to the tool.
•Always wear proper eye and face protection.
Wear safety glasses or face shields when-
ever you operate a Foredom or any power
tool to prevent serious eye or face injuries.
•Secure the work piece or item that you are
working on
in a vise or other work holding
device. Holding it with your hand can result
in serious hand injury.
•Always use a proper dust collection system or
wear a respirator
to prevent the inhalation of
dust particles, polishing compounds, or
other debris into the lungs.
•Do not wear loose fitting clothing or jewelry.
Loose clothing or jewelrycan become
entangled in the rotating accessory. Do not
wear items such as neckties, necklaces, or
bracelets when operating power tools. Be
sure to
tie back or secure long hair.
• Secure power tool to motor hanger or work
surface.
Flexible shaft power tools can
“jump” at start up or vibrate during opera-
tion. The tool should be properly secured in
order to prevent it from vibrating off of the
motor hanger or work bench.
• Never operate any accessory at speeds above
its maximum rated speed.
When properly
used, all of Foredom's accessories can be
operated at the speed ratings listed in the
Foredom Accessory Catalog or specified on
kits and packages.
Always find out the
manufacturer's speed rating before using
accessories other than those from Foredom.

heavy canvas or leather apron. It will protect
you from dust, debris and chips as well as
help prevent injury if the handpiece slips off
the workpiece. It will also help prevent loose
clothing from getting caught in a rotating
cutter, bur or other accessory.
•Never use or continue to use any
accessory which appears to be damaged,
loose, vibrating, or out of balance. Inspect
each accessory for cracks or flaws before
using it. Avoid knots, imperfections in the
wood or metal objects like nails, which
could damage or catch the accessory.
•Always insert the shank or arbor of an
accessory or mandrel into the collet or
chuck of the handpiece as far as possible in
order to provide proper support and tighten
the collet or chuck securely.
•Never use excessive side pressure which
may bend or break the shank or arbor of an
accessory. Let the speed of the accessory
do the work.
•Do not stall the motor by jamming or using
excessive pressure on the accessory. This
can result in damage to the motor or
flexible shaft.
•Never operate the motor with the outer
sheath removed from the flexible shaft.
•Always disconnect the power cord before
servicing the motor or removing the flexible
shaft or sheath.
•Never operate your power tool during a
perceptible power decrease. Turn power tool
off and do not use until power is
fully restored.
•Use proper grounding procedures. This tool
should be grounded while in use to protect the
operator from electric shock. The tool is
equipped with an approved 3-conductor cord
and a 3-prong grounding type plug to fit the
proper grounding receptacle. The green (or
green and yellow) conductor in the cord is the
grounding wire. Never connect the green (or
green and yellow) wire to a live terminal. If
your unit is for use on less than 150 volts, it
has a plug that looks like sketch A below.
An adapter (sketches B and C) can be used for
connecting plugs as shown in sketch A to
2-prong receptacles. The green colored rigid
ear, lug, etc., extending from the adapter must
be connected to a permanent ground such as
aproperly grounded outlet box. Some juris-
dictions, including Canada, prohibit the use
of 3 to 2 prong adapters. Where prohibited,
they should not be used. Use only 3-wire
extension cords that have 3-prong grounding
type plugs and 3-pole type plugs and 3-pole
receptacles that accept the tool’splug. Always
disconnect the power cord before servicing
the tool. Never use in an area where
flammable vapors are present.

N ever change motor direction
while the motor is running.
OFF– no rotation.
FORWARD –counterclockwise shaft rotation.
Forward is going to be the most commonly
used setting. Right-handed people will get the
most control in the forward direction.
Forward Motor Rotation
•ONLY use chisel or hammer handpieces in
Forward rotation. Using a chisel or hammer
handpiece in reverse can damage the hand-
piece, flexible shaft, motor and may
cause injury.
•Use the forward motor direction ONLY for
fluted burs, drills and cutters. Most will cut
efficiently only when turning in this direction.
•Many mandrels have right-hand threaded
arbor screws, which will unscrew in the
reverse direction.
•Dust and debris flies away from the user
when operated in forward in the left hand.
REVERSE –clockwise shaft rotation.
Advantages of Reverse Rotation
•Left-handed users will have better control in
the reverse direction.
•For right handed use, dust and debris flies
away in reverse.
•Alternating motor direction helps to extend
the life of mounted abrasive points, buffs,
brushes, sanding bands, and Typhoon®burs.
•Reverse helps with accomplishing symmetri-
cal grinding and carving techniques.
•Reverse is good for “backing out” stuck drill
bits and extending the life of sanding bands
and abrasive accessories.
•Alternating motor direction makes it easier
and faster to polish metals.
•Be sure to use a mandrel with a left-hand
threaded arbor screw.
•Be sure to insert the shank of the
accessoryas far as possible into the collet
or chuck to give it maximum support.
• Always wear proper eye and face protection.
Wear safety glasses or face shields when-
ever you operate a Foredom or any power
tool to prevent serious eye or face injuries.

Assembly Instructions
Always make sure your power tool is
unplugged during assembly!
After identifying all the components of your
power tool, assemble it in the following manner:
Assembly and Adjustment of Flexible Inner
Shaft, Outer Sheath, and Handpiece
Proper assembly and adjustment of the
flexible shaft and sheath are critical for the
correct operation of your Foredom power
tool. The exposed tip (handpiece end) of the
flexible shaft
(with handpiece
removed) must
extend 3/4″
(19mm) beyond
the sheath.
Important Note:
The shaft and sheath should be checked
and adjusted (if necessary) even if you
received them assembled and attached
to the motor!
2. With the handpiece removed, place the entire
unit on a flat surface with the shaft and sheath
extended straight. Loosen the set screw on the
motor connector. Adjust the exposed tip (hand-
piece end) of the flexible shaft so that it extends
3/4″(19mm) beyond the sheath, as shown
above. This is done by moving the sheath in or
out of the motor connector (motor end) as
shown at left.
3. When the correct adjustment is made,
re-tighten the set screw in the motor connector
and re-attach handpiece onto the flexible shaft.
IMPORTANT!
Please follow these directions to
assemble and adjust the shaft
and sheath.
To check the shaft and sheath you must first
remove the handpiece.
1. The handpiece is easy to remove from
the flexible shaft. To remove, simply pull the
handpiece off the shaft and sheath with a firm
grip. To re-attach, look into the back end of the
handpiece for the keyway. Be sure that the key
tip of the flexible shaft is properly lined up with
the keyway slot in the back end of the handpiece
and push it on. If it is not in line, turn the shaft
tip or the handpiece to the correct position
(see illustration below).

Be sure to follow the grounding
instructions on page 3 of this manual
while attaching the speed control to a
power outlet.
Wait for motor to stop rotating
before switching between forward
or reverse.
To turn motor off, remove foot from foot pedal
speed control, or turn dial speed control to “off”
position, and set rocker switch to “off” (center)
position on motor.
Connecting the Foot Speed Control
The electrical specifications for your power tool are
listed on the label on back of motor. It shows proper
voltage and currents to use with your power tool.
A 115 Volt, 50/60 cycle (Hz) motor can be used with
the models C.FCT-1 and C.SCT-1 foot controls on 115
Volt AC current only. The 230 Volt, 50/60 cycle (Hz)
motor can be used with the models C.FCH-2 and
C.SCH-2 foot controls on 230 Volt AC current only.
To connect the foot control to the motor, insert the 3-
prong plug on the end of the motor power cord into
the socket connector on the shorter power cord on
the foot control. With the motor fwd/off/rev switch in
the “off” position, plug the 3-prong plug on the
longer power cord from the foot control into a proper
3-prong power outlet.
When your foot is not pressing the foot
control, the motor should not be running.
Your foot must maintain steady contact with the pedal
during operation. Holding the handpiece in your hand,
put the motor fwd/off/rev switch in the desired “on”
position, begin with a light touch, start out slowly
and gradually increase the
speed. Finding the right speed
for any specific task is a
matter of experimentation
and experience.

Hanging Motor Installation
M.SR Motors should be hung up
about 30″–40″above the work
surface and to the right of the
work if you are right handed or to
the left of the work if you are
left handed.
Use a safety clip or hook like the
one shown to prevent the motor from jumping or
twisting off an open hook at start up or during use.
Properly securing the motor will help to prevent
injury to the user.
All Foredom motor hangers have this type of safety
clip (see page 15). If an “open hook” is used be sure
to secure the motor to it with wire or heavy tape.
Connecting the
Table-Top Dial Speed Control
The motors can also be used with the C.EM-1 (115
volt) or C.EMH-2 (230 Volt) dial speed control on AC
current. Connect the control to the motor by inserting
the 3-prong plug on the end of the motor power cord
into the socket connector on the shorter power cord
on the dial control. With motor fwd/off/rev switch in
the “off” position and the dial indicator arrow also
in the “off” position on the control, plug the
3-prong plug on the longer power cord from
the dial control into a proper 3-wire outlet (see page
3). Holding the handpiece in your hand, put the
motor fwd/off/rev switch in the desired “on”
position, begin with a light touch, start out
slowly and gradually increase the speed.
Finding the right speed for any specific
task is a matter of experimentation
and experience.

Do not bend shaft and sheath
at tight angle
Shafts and sheaths last longer when they are used
without sharp bends. If used at angles or loops,
wear will occur at the points of greatest friction.
When operating your Foredom tool be careful not
to bend the flexible shaft too much at either the
handpiece or motor shaft connections. Excessive
heat and wear will occur if the bend is too great.
Follow these guidelines for trouble-free use:
a 4″or larger radius, as shown, should be
maintained for shafts on all motors. In its normal
curved position All Foredom SR Series flexible
shaft power tools can tolerate up to 12 lbs. of
torque. There is no way to avoid ultimate wear and
under normal conditions a flexible shaft machine
may require several replacement shafts and
sheaths during its lifetime. (Follow shaft and
sheath assembly instruction in the Assembly
section of this manual.)

General Guidelines
Read all the safety instructions in this
manual before operating your Foredom®
Power Tool. Proper eye and face protection
must be worn to protect you from injuries
caused by flying debris, chips, or sparks
which might result from the work
being done.
It is possible to use rotary or chisel
handpieces not made by Foredom with
your Foredom flexible shaft power tool.
However, this is not recommended since
their function and safety cannot be
assured by Foredom.
Your Foredom motor may be operated in a
vertical or horizontal position, but it should not
be enclosed or confined so as to restrict air
circulation. If the motor is hung up above a
workbench, be sure it is fastened securely to
the wall or motor hanger. The motor may devel-
op a high operating temperature (up to 100oF +
ambient) after prolonged use, and it will be too
hot to hold. This will not harm the motor which
is designed to operate at this temperature for
prolonged periods.
Do not force the tool
Let the speed of the tool do the work. Avoid
using too much pressure. Generally, slower
speeds are used for rougher, heavier work or
when greater control over the accessory is
required for precise, delicate work. Higher
speeds are used for buffing, cutting and
polishing. Read Accessory Recommendations
on page 11 of this manual.
Voltage Decreases
Never operate a power tool during a perceptible
power decrease. Turn off tool and unplug until
full power is restored.
Always wear proper eye and face
protection when operating a Foredom
power tool.
Wait for motor to stop rotating before
switching between forward or reverse.
To turn motor off, remove foot from foot pedal
speed control, or turn dial speed control to “off”
position, and set rocker switch to “off” (center)
position on motor.

Ruby Carvers have ruby crystals firmly bonded to
ametal frame. These long lasting abrasives provide
asmooth finish on hard materials such as steel,
porcelain, glass, acrylic, soft and precious metals
and wood. Unique CeramCut Blue
®
Stones are
made from a mixture of special man-made ceramic
grain and aluminum oxide bonded together. The
ceramic provides a faster cutting action and is
more durable so burs hold their shape longer than
standard abrasives. They are ideal for use on any
hard metal such as steel, stainless steel, chrome
cobalt, platinum and titanium, as well as on wood.
Unique V Stones
TM
have extra hard and long lasting
vitrified aluminum oxide and ceramic grain with a
special glass bead binder that makes them
extremely long lasting, cool running and very
aggressive — 40 to 60 grit. They work on the
same materials as CeramCut Blue Stones, but
much more aggressively. Unique Scotch-Brite
TM
Radial Bristle Discs from 3M have thin flexible
plastic bristles that get into hard to reach areas on
flat and curved surfaces. Use on metal, acrylic,
plaster,ceramics and wood without the need for
compounds. These long lasting abrasives come in
many size diameters and grits. Unique Scotch-
Brite
TM
EXL Unitized Wheels from 3M in 1/2″, 1″
and 3″diameters are ideal for light deburring,
oxide and fire-scale removal, cleaning, blending
and decorative finishing on all metals. Unique CW
Ceramic Impregnated Polishing Wheels are used
for smoothing and polishing precious metals
including platinum, gold, and silver. They also work
on titanium, chrome cobalt, and all hard alloys.
Wheels are 7/8″in diameter and come in six grits.
Burs and Cutters
Vanadium Steel Cutters are suitable for all
materials except hardened steel and glass. They
are used for cutting grooves and countersinking in
soft materials, carving and hollowing woods, slot-
ting and grooving woods, plastics, etc. Steel
Cutters are good for shaping, grooving, slotting
and cutting in wood, plastic and soft metals. Use
Carbide Burs on wood, plastic and tough alloys.
Carbide is generally referred to as the “hardest
man-made metal”. Engraving Burs are used for
fine detailed work on metal and other hard materi-
als. Generally use medium speeds for stock
removal and higher speeds for finishing work
and when using smaller points.
Cut-Off Wheels are used to cut off, groove, and
trim metal, wood and ceramics.
General Accessory
Recommendations
Foredom’s wide assortment of rotary accessories
makes your flexible shaft power tool very versatile.
Use it for grinding, sanding, carving, engraving,
brushing, cutting, buffing, and polishing on virtually
any material. The Foredom Accessory Catalog offers
the right accessories for your specific applications.
Accessories may be purchased from your local
dealer or directly from Foredom.
Always let the speed of the power tool do the work.
Avoid forcing the tool or applying too much pressure.
Experience will help you choose the right speed for the
work you are doing. It's always a good idea to practice
on a scrap piece of the same material you plan to use
to determine the best accessories and speeds.
Always follow the manufacturer’s RPM or speed
recommendations when selecting accessories.
Your motor is supplied with a variable speed control
that allows you to operate it at the most suitable
speed for each job. The motor has a maximum speed
rating of 18,000 RPM.
Always use an accessory which has the same
or a higher speed rating than your tool. Using an
accessory with a lower speed rating can result
in serious injury.
Rotary Accessories and Motor Rotation: Running the
motor in forward and reverse can help to extend the
life of mounted abrasive points, Typhoon
®
burs, buffs,
and brushes.
Use only the forward motor direction for fluted
burs and cutters. Most will cut efficiently
only when turning in this direction.
Abrasive Points, Wheels, and Discs
Use Aluminum Oxide (red color) for fast cutting
on high-tensile, tough materials such as steel and
malleable iron. Also use on glass and porcelain, etc.
Aluminum Oxide (white color) points have an
extremely fine grit for producing a fine, high finish on
high-tensile materials including stainless steel and
glass. Use Silicon Carbide (green color) for low-
tensile, brittle or “smeary” types of metals such as
aluminum or brass. They are ideal for use on any hard
metal such as steel, stainless steel, and titanium, as
well as wood. Rubber Bonded Abrasive Wheels are
used for removing rust and for polishing with various
grits. For best results, use finer grits for finishing at
high speeds and coarser grits for stock removal at
lower speeds. Abrasive Discs are for grinding,
smoothing, and cleaning glass, high speed steel,
and other tough materials.

Unique Typhoon
®
Carbide Burs provide very fast and
aggressive material removal. Made for use on soft
and hard woods, diestone, and plastics (do not use
Typhoon burs on metal). They have aligned teeth that
leave a smoother finish than other types of non-flut-
ed tungsten carbide burs. Professional Jeweler’s
Burs with 2.35mm (3/32″)shanks are for jewelry
making applications.
Drills
Step Drills are used to drill wood, precious metals,
mild steel, bone, and mother of pearl. Diamond
Coated Twist Drills,made of wire gauge steel with
diamond coating, are used to drill extremely fine
holes in stone, ceramics, tile, glass, and hard metals.
Plated and Sintered
Diamond Points and Discs
are used to remove stock from extremely hard
materials such as tungsten and tantalum carbide
cutting tools, dies and molds, broaches, and for
grinding and pre-polishing synthetic jewels and
precious metals, fiberglass and reinforced plastics,
PVC and ceramics. Sintered diamonds last far longer
than plated diamonds and can be re-sharpened as
desired with a wet dressing stone to expose new
diamond particles.
Sanding Drums, Bands, Discs,
Cartridge Rolls and Flap Wheels
These are used for removing rust, smoothing rough
surfaces and for sanding jobs on wood, plastic and
metal. (Avoid using too much pressure which will
cause clogging or a build-up on the work surface.)
For best results, use medium speeds for coarser grits
and larger diameters. Use higher speeds for finishing
work or with smaller sizes. Also available are various
shapes of 1″Cartridge Rolls and Flap Wheels for
mounting on mandrels Unique 3M Ceramic Purple
Coated Abrasive Bands and Discs contain patented
Cubitron
TM
ceramic aluminum oxide mineral that
sharpens itself with use. They last 2 to 4 times longer
than traditional aluminum oxide discs and remove
material faster with less heat and loading.
Cotton or Felt Bobs and Buffs
Solid Felt Buffs or Bobs are used in combination
with gritty or smooth compounds for a variety of
buffing and polishing operations on plastic, wood,
and metal. They vary in shape and come in three
hardnesses — medium, hard, and rock hard.
Loosely-stitched Soft Cotton Buffs are used for
delicate work on precious metal and during polishing
operations. Generally use high speeds for cutting
down and buffing. Medium speeds are used for
more delicate, precise work and for polishing.
Brushes
Miniature Power Brushes are generally used on
metal surfaces and hard-to-reach areas. They are
ideal for deburring, surface finishing, edge blending,
roughening to create a good bonding surface, and
general cleaning. Use high speeds for cleaning and
deburring. Medium speeds are needed when clean-
ing hard-to-reach areas and edge blending. Unique
Scotch-Brite
TM
Radial Bristle Discs from 3M have
thin flexible bristles that get into hard to reach areas
on flat and curved surfaces. Use on metal, acrylic,
plaster, ceramics and wood without the need for
compounds. They can sand, smooth, polish, or
burnish metal, plastic, or wood to a bright finish.
Friction Grip Burs and Points
Hard to find Carbide burs and diamond coated
points with 1/16″(1.6mm) shanks for use in high
speed air turbines and Foredom collet handpieces
with 1/16″(1.6mm) collets. These accessories can
also be used with adapters in micromotors.
Compounds
Foredom has seven different compounds.
In addition to Emery, Tripoli, and Red and White
Rouges, there is unique Platinum Blue for
pre-polishing and cutting down platinum and other
metals, and for final polishing unique Platinum
White (8000 grit) that produces a deep luster on
platinum, other metals, and acrylics. Carnauba is
the hardest wax available. It produces a high luster
on wood and painted surfaces.
Bur and Tool Holders
Foredom has four rotating bur holders and two
small holders with covers. Two of the rotating
models have center cups for holding small tools
such as files and screwdrivers. A bur holder is the
perfect companion product for your collection of
burs, drill bits, and other accessories of various
size shanks.

Exposing the Inner Shaft
1. Remove
handpiece
(see page 5).
2. Loosen set
screw on motor
connector.
3. Slide outer
sheath out of
motor connector
and wipe
shaft clean.
4. Apply a very
light coating of
lubrication to shaft
starting at the top
and working
downward to
about one inch from the handpiece end. Apply
grease with your finger tip or small brush. Don’t
overdo, apply a light film of grease. Once the
machine is running, the shaft itself will spread the
grease. If too much grease is applied, the excess
will work its way into the handpiece and eventual-
ly seep out between the handpiece and sheath.
For this reason, apply a bit less near the hand-
piece end of the shaft.
Never operate the motor with the outer
sheath removed from the flexible shaft.
5. Replace and adjust sheath so that shaft key tip
extends 3/4″(19mm) from sheath. Retighten the
set screw in motor connector. See page 5, No. 2.
6. Clean outside of sheath by wiping with
acloth.
7. Hang motor over a trash can and run it for
about 10 minutes before attaching the hand-
piece. This provides enough time for the grease
to warm up,
spread and drain
off. Wipe off any
excess grease at
tip end of sheath.
8. Re-attach
handpiece.
IMPORTANT!
Maintenance Procedures
Always make sure your power tool
is unplugged during maintenance
procedures!
It is very important to routinely clean your
Foredom®Power Tool and lubricate the shaft
(NOT the motor), especially in areas that
generate a lot of dust.
Dirt and improper lubrication are the most
common causes of poor operation and
excessive wear.
Always disconnect power tool before
cleaning or servicing.
Note: The motor has permanently
lubricated ball bearings and does not
require additional lubrication.
Routine Cleaning of Motors
Foredom Motors
need air circulation
through the motor
housing to remove
waste heat and cool
the windings. Inlet
and outlet slots
provide the means for air flow. However, saw dust
and conductive debris (like metal filings or gold
dust) can enter in through these slots. If not
cleaned regularly, dust can collect, making a
bridge between parts, causing an electrical short.
In high dust environments, Foredom
recommends cleaning the motor every
40 hours of use.
Toremove dirt and dust buildup, motor brushes
should be removed, cleaned and replaced, and air
should be blown through the motor.
Routine Cleaning and
Lubrication of Flexible Inner Shaft
The shaft should be checked, wiped clean, and
relubricated with grease every 50 hours of use.
With every 200 hours of use, the shaft should be
thoroughly cleaned with solvent and lubricated.
Use Foredom flex shaft grease (p/n MS10006)
or high quality white lubricating grease.

Shaft and Sheath Adjustment
Place the entire unit on a flat surface with
shaft and sheath extended straight.
Adjust the exposed tip of the flexible shaft
at the handpiece end so that it extends 3/4″
(19mm) beyond the sheath.
This is done by moving the sheath in or out
of the motor connector. When the correct
adjustment is made, tighten the screw in
the motor connector.
Replacement of Motor Brushes
Motor brushes should be checked for wear
periodically. When new they are approximately
3/4″(19mm) long. Replace them when they
have worn to 1/4″(6mm). To remove brushes,
disconnect motor power cord and unscrew the
brush caps. Remove the worn motor brushes,
replace with new motor brushes, and screw
motor brush caps back on. Be sure to replace
both motor brushes even if one of them is less
worn than the other.

Always make sure your power
tool is unplugged when conducting
maintenance procedures!
Replacement of
Worn Shafts and Sheaths
Shafts and sheaths last longer when they are not
used at sharp angles or loops, since wear occurs
at the points of greatest friction. There is no way
to avoid ultimate wear, and under normal condi-
tions a flexible shaft machine may require several
replacement shafts and sheaths during its lifetime.
Toexpose the inner shaft follow steps 1, 2, and 3
on the previous page.
Next, remove motor
connector with 1″
open end or
adjustable wrench.
Motor connector
has a left hand
thread and must
be turned clockwise (right) for removal.
Loosen set screw on the flexible shaft motor
coupling and slide shaft off the motor shaft.
Installation of New Shaft
1. After removing old shaft, loosen set screw on
the new flexible shaft motor coupling and slide
coupling onto motor shaft.
2. Tighten set
screw securely
onto the flat of the
motor shaft.
3. Grease shaft prior
to putting on the
sheath. (See lubrica-
tion instructions on
page 13.)
4. Slide motor
connector back up
over the shaft and
tighten to the left
(counterclockwise).
5. Slide sheath over flexible shaft with plain
fitting directed toward the motor and into the
motor connector. (Each end of the sheath has a
metal fitting. One is plain, the other has a groove
around it to fit the handpiece.)
6. Adjust the shaft (page 5 and top right) and
tighten sheath set screw in motor connector.
