off. Wipe off any excess grease at tip end of
the sheath.
8. Re-attach handpiece.
Never operate the motor with
the outer sheath removed from
the flexible shaft.
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
conditions a flexible shaft machine may require
several replacement shafts and sheaths during
its lifetime.
Installing New Shaft
1. Expose and remove the inner shaft following
steps 1, 2, and 3 at left.
2. Loosen 3/32 ″ hex set screw on the flexible
shaft motor coupling on the shaft. Replace with
new shaft.
3. Tighten set screw securely onto the flat of
the motor shaft.
4. Grease shaft prior to putting on the sheath.
Follow lubrication instructions at left.
5. Thread new shaft through sheath
and silencer spring. Tighten sheath nut
(counterclockwise).
6. Hang and run the motor for about 10
minutes before attaching the handpiece to allow
enough time for the grease to warm up, spread
and drain off. Wipe off any excess grease at tip
end of sheath.
7. Re-attach handpiece.
Assembly Instructions
Always make sure your power tool
is unplugged during assembly.
Connecting and Removing square drive
handpieces with locking rings to Series TXH,
SRH, LXH, and H flexible shafts–
1. Pull back
the locking ring
toward the front
end of the
handpiece while
you insert the
tip of the flex
shaft. You may need to rotate the handpiece slightly
until the square shaft tip engages the spindle.
2. Release the
locking ring
when you feel
the shaft
connect to the
handpiece. You
should hear
a click.
3. To remove a
handpiece, pull
back the locking
ring in the same
way and with a
strong action
remove the
shaft and sheath
from the
handpiece.

Routine Cleaning and Lubrication
of Flexible 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 (MS10006) or
high temperature, quality white lubricating grease.
Exposing the Inner Shaft
1. Remove handpiece
2. Use a 1 ″ adjustable wrench to remove the
outer sheath.
Sheath nut has a left hand thread and must be
turned clockwise (right) for removal.
3. The inner shaft is threaded through both a
silencer spring and the outer sheath. Slide the flex-
ible shaft out of the outer sheath to lubricate or
replace the it. The silencer spring tends to stay
inside the sheath – so it may not be visible when
you remove the inner shaft.
4. Apply a very light coating of lubrication to shaft
starting at the top and working downward to about a
few inches from the end. Apply grease with your fin-
ger tip or small brush. Don’t overdo, apply a very
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 eventually seep out between the
handpiece and sheath. For this reason, apply a bit
less near the handpiece end of the shaft.
5. Replace both spring and sheath and tighten
sheath nut (counterclockwise).
6. Wipe the exterior of sheath with a cloth.
7. Hang and run the motor for about 10 minutes
before attaching the handpiece to allow enough
time for the grease to warm up, spread and drain

Maintenance
Always make sure your power tool
is unplugged when conducting
maintenance procedures!
Motor – No lubrication of the motor is required,
however, it is important to keep the motor clean.
Remove any build up of dirt, chips, dust, or other
debris that may have entered through the slots
in the motor housing using a brush or by blowing
air through the motor (shown at right). It is also
important to check for and replace worn motor
brushes periodically – see page 4 and read
your manual for instructions.
Square Drive Handpieces – No lubrication
is required. Remove any build up of dirt, chips,
dust or other debris from collet seat or chuck.
Read the handpiece instructions for
additional information.
Speed Controls
Motors featured in this insert must be used in
combination with the speed controls shown
below. Damage to the motor will result if used
with the wrong control. Do Not plug the motor
directly into an AC electrical wall outlet.
