Assembly Instructions
Make sure the power switch on the back of the
control box is turned off. Check to see that the
voltage selector switch on the back of the control
box is set to the voltage to be used 110 or 220
volt. Next:
1. Connect the power cord
into the back of the
Control Box and into a power outlet.
2. To use the Foot Contol
, plug the Foot Control cord
into the port on the back of the control box. Align the
pins carefully and tighten the locking ring.
2. Plug the Handpiece
cord into the port on the front

en the locking ring.
3. Set the Speed Dial to '0'.
4. Make sure the handpiece collet is in the locked

and that the
collet and accessory can spin freely.
There are 2 dots on the metal ring – one will
line up with the Unlock symbol and the other
dot will line up with the Lock symbol when
you twist the front of the handpiece.
Operating the handpiece with the collet in the
open or Unlock position or with no bur or bit
in it can cause se vere damage to the motor
Operating Instructions
1. Be sure the On/Off Power Switch lights up when
you are ready to work. The switch must be in the

Always turn the Dial to '0' and On/Off Switch to
the Off position when not in use.

CAUTION Never run the handpiece when the
collet is open or in the intermediate position.
The spindle is locked and will not turn. This
will damage the motor.
Fuse Protection
1. To change a fuse
Unplug the power cord from
the AC receptacle in the back of the control box
to expose the Fuse Compartment.
2. Use the blade of a small screwdriver
in the
slot of the fuse holder and gently pry outward.
The active fuse is in the back of the holder and a
spare fuse is in the front compartment. If the
glass case of the active fuse is darkened, the fuse
is blown. From the underside of the drawer, push
out the blown fuse using a small screwdriver.
Be sure the micromotor is not being overloaded,
the line voltage is not low, and then replace the
blown fuse with the spare fuse. It is a good idea
to always keep a spare fuse in the front compart-
ment to avoid lost time if there is a future blown
fuse. To avoid overloading the micromotor
always use the same type and ampere rating as
the original: GDB 5 Amp, 250V, 5mm x 20mm.
If, after replacement, the fuse blows again, the
micromotor has a fault. The unit should be analyzed
by a qualified technician, or returned to the factory
for service. See Repair Services.

Maintenance
The H.MH-160 has permanently lubricated ball
bearings that do not require lubrication. Putting
even a small amount of oil into the handpiece can
damage it.
Cleaning the Handpiece
Use the Handpiece in as clean and dust free an
environment as possible.
If the Micromotor Handpiece is used for wood-
carving, it should be cleaned after every use.
A cloth with a small amount of alcohol solution
can be used to clean the outside of the hand-
piece if necessary.
Do not use any other cleaning fluids or
immerse handpiece in any liquid.
The H.MH-160 Handpiece is
not autoclaveable.
Cleaning the Bore in the Spindle
If you are working in dusty conditions or
generating a lot of dust particles you may need
to remove the collet for cleaning. With front of
Handpiece in ‘Unlock’ use a Q-tip to clean out
the bore in the spindle.
The metal nose cone needs to be tight
to hold the front housing in place, to insure
that the the full stroke of the collet operat-
ing mechanism works properly.
