Safety
Instructions
A Micro Grinder Handpiece is a high
speed rotary power tool which can be
dangerous and cause serious injury if it
is not used properly.
NEVER operate it without wearing
eye protection.
• ALWAYS wear proper eye and
face protection.
• ONLY use accessories rated for
speeds of 20,000 rpm or higher
when operating this micromotor.
• ALWAYS observe the manufacturer's
maximum speed rating when using
any accessory.
• NEVER use or continue to use any
accessory which appears to be damaged,
loose, vibrating, bent, or out of balance.
Inspect each accessory for cracks or flaws
before use.
• ALWAYS insert the shank or arbor of an
accessory or mandrel into the chuck of the
handpiece as far as possible in order to
provide proper support and close the chuck
securely. DO NOT use accessories with
shanks that are less than 1
″ long.
• NEVER use excessive side pressures
which may tend to 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 mounted
point, buff, wheel or accessory. This can
result in damage to the motor.
• WEAR a dust protector to prevent the
inhalation of harmful dust or debris from
grinding, carving or other operations per-
formed with this power tool.
• 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 properly 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.
• USE a dust collector (vacuum system) to
pull sawdust, grinding dust, or other debris
away from the work area and the control
box and handpiece intake vents.
• NEVER plug the Handpiece into
the Variable Speed Foot Control
Connection Port on the back of
the Control Box.
• ALWAYS plug the Handpiece into
the Handpiece Connection Port on the
Front of the Control Box.
• DO NOT operate the handpiece in the
presence of any flammable liquid or gas.
Assembly Instructions
Do not plug into a power outlet
before connecting the handpiece
or foot pedal. 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.

Connecting Handpiece
Attach the Micro Grinder handpiece to
the control box by plugging the coiled cord
into the Handpiece Connection Port on the
lower right side of the front control panel
(Figure 1). Use keyway for proper alignment
when plugging in the cord.
NEVER plug the handpiece into the
Variable Speed Foot Control
Connection Port.
Connecting
the Variable
Speed Foot
Control
The Variable Speed
Foot Control is
suitable for either
110 or 220 volt
operation. Attach it
by inserting the connector into the Variable
Speed foot control connection port on the
rear panel of the control (Figure 2) using
the keyway for proper alignment. It is not
necessary to have the foot pedal connected
to the control box to operate the dial speed
control. The Micro Grinder control and
handpiece are now ready to operate.
Connecting Power Cord
Before connecting the power cord plug
(Figure 2) to a power outlet, select the
proper voltage (110 or 220v) on the back
of the control box. Put the On/Off Selector
Switch in the OFF position and turn the dial
speed control to the OFF speed position.
Now plug in the power cord to an AC
current outlet.
Connecting Optional On/Off
Foot Switch
This switch (p/n
HP4-927) is avail-
able separately
and attaches by
inserting the
connector into
the On/Off foot
connection port
on the rear panel
of the control
(Figure 2) using
keyway for proper alignment. This switch
allows you to turn the motor on and off
without changing the speed set by the dial.
Operating Instructions
for HP4-917 Control Box
1. Power On/Off Switch
When the Power On/Off Switch is in the ON
position the switch lever will light up. This
switch must be in the ON position for
the handpiece to run with either the
dial speed control or the foot speed
control selected.
Always turn the Dial and Power On/Off
Switch to the Off position when not
in use.
2. Hand or Foot
Selector Switch
With the Dial and Power On/Off Switch in
the OFF position, select either foot or hand
speed control.
• With the Speed Control Selector Switch in
the Hand position, the handpiece will run at
the speed set by the Dial Speed Control.
• With the Speed Control Selector Switch in
the Foot position, the handpiece will not
operate until the Foot Pedal is depressed.
3. Forward/Reverse
Rotation Selection Switch
With the Power On/Off Switch in OFF
position, select the desired handpiece
rotation by moving the switch to Fwd. for
FORWARD or Rev. for REVERSE rotation.
Changing handpiece rotation
direction while in operation is
not recommended.
4. Regulating Speed
• The Dial Speed Control varies the
speed of the handpiece from minimum to
maximum when the Speed Control Selector
Switch is in the Hand position.
• The Dial also controls the maximum
speed that can be reached when using a
foot pedal.
To achieve maximum speed with a foot
pedal, the dial speed control must be
turned all the way to the Max setting.
5. Handpiece
Overload Protection
The red overload light will come on with an
audible alarm, and the handpiece will stop
when too much load is placed on the
handpiece. Immediately turn off control by
putting the Power ON/OFF switch in OFF
position. Put power switch in ON position
again when overload condition is correct-
ed. There may be a time delay of several
seconds before the overload trip resets. HP4-927
