PH3 20X Slim Rotary Handpiece

Introduction
Instruction Manual
for
20,000RPM Rotary Handpiece
Model: PH3 20X
#510-3330
The Gesswein Power Hand 3 M-20X Rotary Handpiece is engineered and
manufactured to a high degree of precision and will give you many years of
trouble-free service. Backed by a limited warranty that covers wear parts for
90 days and overall balance of parts for six months.
This DC electrically driven rotary motor is designed to be used with the
Power Hand 3 Controller (#510-3300). For use with Gesswein Power Hand 2X
controllers, the PH3 adaptor (#510-3304) is necessary to connect the
5 prong motor plug to the 3 prong controller receptacle. Controllers convert
the Alternating Current (AC) power supply to a variable Direct Current (DC)
by means of an I.C. “transistorized” automatically controlled circuit.
The Gesswein Power Hand 3 rotary motor series consists of six motors
and eight head assemblies with maximum operating speeds ranging from
8,000 to 55,000rpm. The maximum RPM speed is indicated on each motor
case housing.
To connect Power Hand 3 handpieces to Power
Hand 2X controllers, use the PH3 Adaptor 5 to 3
prong reducer plug. #510-3304.

The Gesswein Power Hand 3 Rotary
Handpiece uses a quick-tool-release
mechanism that allows for rapid tool changes.
To operate, turn the Collet Release Ring
toward the arrow pointing to the “R” or release
position (see Fig. 2). When in full “R” position,
the Collet Release Ring will make a click
sound; the collet is then fully open and ready
to accept a tool.

When changing tools, be sure that the
handpiece motor is not running. If you attempt
a tool change under this condition, the motor
will be stalled and damage will occur.

To change collets, rotate the Collet Release
Ring to the full “R” position and remove
the tool in the collet. Hold the collet
between thumb and forefinger and turn in a
counterclockwise direction until the collet is
removed. Insert the new collet and reverse
the procedure. It is best to tighten a replaced
collet by hand with the collet wrench
(#510-0180), securing until just tight.

4. Operating Procedure with Power Hand 3 Controller
If the collet cannot be loosened by hand using
the Collet Wrench, additional torque may be
required. To use the Collet Wrench, place
the triangular cutout in the wrench over the
collet (see Fig. 3), and turn counterclockwise
to loosen and clockwise to tighten the collet.
If more torque is required, hold the handpiece
with the Collet Wrench secure on the collet,
and tap the wrench with a solid tool (see
Fig. 3a) in a counterclockwise direction. This
procedure will loosen the collet, which can
then be removed by hand.
If the handpiece collet is so tight that the
above procedure will not loosen it, then
remove the Head Assembly from the Motor
Assembly. This can be done by grasping the
Motor Connecting Ring (see Fig. 1) and pulling
upward. Insert the Chuck Joint Wrench (see
Fig. 3b) into the Nylon Coupler (#510-0151),
hold the Head Assembly and Chuck Joint
Wrench securely in one hand, and with the
Collet Wrench in place on the collet, loosen
in a counterclockwise direction (for parts
drawing, refer to page 11.)
After a collet is replaced, be sure that the
Collet Release Ring is rotated to its full “S”
position and that the collet rotates freely
when turned by hand. If the collet does not
rotate freely, it is not fully seated in the Head
Assembly, and you must repeat the removalreplacement procedure.
With your rotary handpiece fitted with a selected tool, connect the Gesswein
Power Hand 3 Controller to an electrical supply and the handpiece to the
A motor or B motor output socket.

Put the Controller Main Switch to the “ON” position, which lights up the LED
lights of controller. Then select the A motor or B motor button depending
on which socket the handpiece is plugged in to. Check to make sure the
desired rotational direction is selected on the Fwd./Rev. button. Then press
the START/STOP button to supply power to your handpiece. RPM speed is
adjusted by the round dial in the center. It is always best to start at minimum
RPM and then increase to the desired RPM speed.
A Load Indicator light is located on the front panel of the PH3 Controller with
8 steps of LED lights from green to yellow to red. The display lights up as
force is being applied to the handpiece. For best results and long life, stay
within the green.

5. Precautions
6. Replacement of carbon brushes
A.Before operating your handpiece, be sure that the Collet Release Ring is
in the “S” or secure position. Failure to do so (referred to as “locked rotor
condition”) will cause the motor to stall and could possibly cause motor
damage.
Gesswein Power Hand 3 motors use a spring tension-type carbon brush
assembly. The approximate life of these brushes is 800-1,000 hours. Use the
set of two replacement carbon brushes supplied with your handpiece when
it becomes necessary to replace worn brushes. (Brushes should be changed
when handpiece is not running at maximum speed, or if it sounds as though
it’s running out of gas.) Please note that in the event you must change the
brushes, it is important that both be replaced at the same time. Replacement
of only one carbon brush will cause motor damage.
B.Do not attempt to change tools or rotate the Collet Release Ring while the
handpiece is running. This action will stop the motor abruptly, cause parts
damage, and could also possibly cause motor damage.
C.During use, avoid stalling the motor by pushing too hard on the work tool
or by exceeding the torque capacity of the handpiece motor.
D.The Gesswein Power Hand 3 Rotary Handpiece is designed not to
overheat with normal use. It can be used continuously and will provide
efficient, longlife performance if you apply just enough machining and
polishing pressure to maintain full motor speed.
E.The 3⁄ 32" (2.35mm), 1⁄ 8" (3.2mm) and 3.0mm collets are manufactured to
accept 3⁄ 32", 1⁄ 8" and 3.0mm ± 0.0008" shank tools respectively. Use only
tools that correspond to the collet size being used.
F.Do not use your handpiece in water or oil, and never allow any oil, water
or other fluids, dirt, or wood dust to enter the inner casing. Failure to
keep foreign matter out of the inner casing will cause damage to the ball
bearing assemblies.
Instructions for replacing carbon brushes
1. Disconnect the handpiece from the controller.
2. Remove the screw on the back of the motor cover.
3. D
etach the motor cord from the motor by grasping the motor cord and
pulling backwards. Do not hold the motor cap when pulling backwards
to avoid damaging the On/Off switch (Fig. 4).
Fig. 4
G.Do not subject the power cord on the handpiece to sharp bending or
rough treatment. Such treatment could break the cord wires or damage
the male connecting pins and female cord connectors.
H.Be careful not to point the handpiece at any part of the body while it is
running, particularly during startups.
I.Be careful when using Wire Burnishing Tools. DO NOT USE THESE TOOLS
AT SPEEDS FASTER THAN 14,000 -15,000RPM. Each tool is made of
individual piano wire. Operating a Wire Burnishing Tool at higher than
recommended speed could cause the wire to come free from the hub.

4. R
emove the 2 carbon brush screws and take out the carbon brushes. Be
careful not to lose screws.
5. Install the new Carbon Brushes and secure with screws (Fig. 5).
8. A
lign the On/Off motor switch with the square hole of the motor cap, and
gently insert motor cap (Fig. 7 & 8). Then insert the motor cap screw.
Fig. 7
Fig. 5
6. Gently
push down the On/Off motor switch to free the motor cord from
the motor cap. Be careful not to damage the On/Off motor switch. Then
plug the motor cord back into the motor (Fig. 6)
Fig. 8
Fig. 6
9. W
hile the power is off, plug handpiece into controller. Please speed up
gradually from minimum RPM and make sure nothing is abnormal with
behavior.
7. D
ust Removal - From time to time, it will be necessary to clean excessive
dust that accumulates in the motor cover. To remove this dust, remove
the motor cap (see instructions for replacing carbon brushes to remove
motor cap). If compressed air is available, use it inside the cover and the
motor armature air cooling vent. If air is not available, remove excessive
dust with a dry brush. If necessary, use a cloth moistened with detergent
to clean the cover, and blow into the air cooling vents to clean around the
armature. DO NOT USE any volatile liquid as a cleaner (i.e. paint thinner
or alcohol).
10. L
ubrication - Lubrication of your Gesswein Power Hand 3 Rotary
Handpiece IS NOT NECESSARY, and you should NOT let oil or other
fluids enter the Head Assembly (see Precautions).
Periodically cleaning the inner threads on handpiece collets will ensure
their easy collet removal when changing sizes. Twist a clean rolled-up
piece of tissue paper in and out of the threaded area.
