Assembly Instructions
Do not plug into power outlet before connecting handpiece or
foot pedal.
Connecting Handpiece:
Attach the handpiece to the control by plugging the coiled cord into the
handpiece connection port on the lower right side of the front control panel
(see Figure 1). Be sure to align pins properly using keyway when plugging in
the cord.
NEVER turn or start the MH-145A Handpiece while chuck is in open
(unlocked) position. This can damage the handpiece. Always operate it
with a bur or other accessory in the chuck and with the chuck in the
closed position.
DO NOT operate the handpiece in the presence of any flammable liquid
or gas.
DO NOT cover the ventilation slots or handpiece motor with cloth or tape.
Air must pass freely through the intake and exhaust ventilation slots to prop-
erly cool the motor. If the power cord or plug to the handpiece is damaged,
repair or replace immediately. NEVER operate with a damaged power cord.
Connecting Foot Pedal:
The Foot Pedal Control can be used with either 115 Volt or 230 Volt models
of the control. Attach it by inserting the foot pedal connector pins into the
foot control connector port on rear panel of control (see Figure 2) using
keyway to properly align pins. Then tighten the threaded locking collar by
turning it clockwise. (It is not necessary to have the foot pedal connected to
the control box to operate the dial speed control.) The Micro Motor control
and handpiece are now ready to operate.

Power On/Off Switch and Indicator Light:
With the Power On/Off Switch in the ON position and the Control Selector
Switch in the MANUAL position, the Power Indicator Light will go on
immediately and the handpiece will run at the speed set on the
Dial Speed Control.
With the Power On/Off Switch in the ON position and the Control Selector
Switch in the FOOT position, the Power Indicator Light will go on but the
handpiece will not rotate until the Food Pedal is depressed.
Control Selector Switch:
With the Power On/Off Switch in the OFF position, select either foot or
manual speed control.
Forward/Reverse Rotation Selection Switch:
With Power On/Off Switch in OFF position, select the desired handpiece
direction by moving switch to FORWARD or REVERSE position. Do not
change handpiece direction while it is running. This can damage the
handpiece motor.
Manual Dial Speed Control:
The dial control will vary handpiece speed from low to full speed. It will only
function while Power On/Off Switch is in ON position and Control Selector
Switch is in MANUAL position.
Handpiece Overload Protection:
If the Handpiece is used with a locking ring left in the “R” position or in
overload condition, it will trigger the overload circuit protector. The Power

Immediately turn off control by putting Power ON/OFF switch in OFF
position. Put power switch in ON position again when overload condition
