Safety Instructions
Before using your Foredom power tool, please
read safety instructions. They are for your protec-
tion 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 whenever 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 jewelry can become entangled
in the rotating accessory. Do not wear items such
as neckties, necklaces, or bracelets when operat-
ing power tools. Be sure to tie back or secure
long hair.
•Secure the 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, work bench or wall.
•Never use 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 packaging. Always find out the
manufacturer’s speed rating before using ac cessories other than those from Foredom.
•For added safety and comfort while using
this power tool for carving or other applica tions, it is recommended that you wear a 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 wear open shoes or sandals. Use
footwear that is tough enough to protect
your feet from falling tools.
•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 wood
or metal objects like nails, which could dam age 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
a properly 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’s plug. Always
disconnect the power cord before servicing
the tool. Never use in an area where
flammable vapors are present.
Never change motor direction while the motor is running.
Changing direction while motor is running can damage the motor or
flexible shaft or lead to premature wear. 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.

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.
At Foredom we define motor rotation this way:
Forward motor rotation means that the motor
is turning an accessory (bur, bit, drill, cutter,
etc.) counterclockwise when holding the
handpiece upright in your hand and you are
looking down on to the front of the accessory.
When the handpiece/accessory is applied to
the workpiece, your viewpoint changes to the
back end of the handpiece and accessory and
the forward rotation direction can be
described as clockwise.
Forward Motor Rotation
• ONLY use Chisel or Hammer handpieces or
Angle Grinder attachment for H.30

hand piece in Forward Rotation. Using Chisel or
Hammer handpieces or Angle Grinder
attachment in reverse can damage the hand piece, attachment, flexible shaft, or 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.

with built-in control
A complete Series SR flexible shaft power tool consists of a motor, flexible shaft and
sheath, speed control (foot or manual) and a handpiece. If you purchased a motor and control, a
handpiece will also be needed to operate the machine. Locate and identify all components, parts
and accessories you purchased before discarding the packing list and packing materials that
came with your power tool.
Please follow these directions to assemble
and adjust the shaft and sheath.
To check the shaft and sheath you
must first remove the handpiece
which is easy to do.
To remove:
1. First make sure your power
tool is unplugged. Simply pull the
handpiece off the shaft and sheath with
a firm grip.
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. This
is done by moving the sheath in or out of the
motor connector (motor end). Shown below.
3. When the correct adjustment is made,
re-tighten the set screw in the motor connector
and re-attach handpiece onto the shafting.
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, & Handpiece
Proper assembly and adjustment of the key tip
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!
To Re-attach Handpiece: while holding the black
colored metal outer sheath tip facing upward, turn
on the motor so that it is running at about half
speed and then turn it off. While the inner key tip is
still rotating, grip the handpiece and push it onto the
sheath tip with one firm motion until it snaps into
place (shown at right). This procedure will align the
key tip into the keyway slot (as shown at left). To
verify this, insert and tighten an accessory into
collet or chuck, turn on motor to low speed and
observe that the accessory rotates smoothly.
