Introduction
Gesswein Power Hand 2X Recipro handpieces are manufactured to the highest stan-
dards available to provide many years of trouble-free service. Complete with Powerful
30V DC aircooled motors and sealed bearings. Backed by a limited warranty that covers
wear parts for 90 days and overall balance of parts for six months.
This DC electrically driven Recipro handpiece is designed to be used with Gesswein
Power Hand 2X Single, Standard, Dual, Jewelers’ Micromotor, Power Carver II and
Bright-Cutting Controllers. These controllers convert the Alternating Current (AC) power
supply to a variable Direct Current (DC) by means of an I.C. “transistorized” automatically
controlled circuit.

3. General Use
Tool Holder
The Recipro handpiece Spindle is designed to
accept tools with shank diameters from 1.5 to
4.0mm. To insert the desired polishing tool into
the spindle aperture, turn the Tool-Securing Screw
counterclockwise either by hand or with the tool
pin provided (see fig. 3). Once the tool has been
inserted, be sure to tighten securely by rotating the
Tool-Securing Screw back in the clockwise direction.
Stroke Adjustment
Remove the Recipro handpiece Cover by unfasten-
ing the Cover Screw located at the rear. The Hex
Socket Screw is located on the side of the Eccentric
Shaft. Loosen this set screw with the provided Allen
Wrench (see fig. 4). Stroke lengths are graduated
in millimeters (1.0mm = 0.4") and indicated by red
numbers on the Eccentric Collar. Hold the Recipro
in one hand with stroke adjustment numbers facing
you, and press your thumb against the Eccentric
Shaft. With your free hand, turn the Eccentric Collar
until the selected stroke length lines up with the red
Eccentricity Indicator. Now tighten the set screw
and replace the handpiece cover.
Floating Head
The Recipro handpiece has been designed to allow
the efficient polishing of both curved and flat sur-
faces. Better control can be maintained on a curved
work surface if the tool can float so it is always in
contact with the surface. When the Recipro hand-
piece is in its floating head position, the selected tool
will revolve around its axis 360° in both directions
while reciprocating. The normal fixed head position
is used for flat surfaces and holds the tool parallel to
the surface being polished.
To use the Floating Head feature, turn the Floating
Head-Securing Screw counterclockwise (see fig. 5).
In this position the head will rotate freely around its
axis while polishing. To return to the position of fixed
reciprocation, turn the securing screw clockwise.

4. Operating Procedure
With your Recipro handpiece adjusted for stroke and with a selected tool fitted, connect the
Gesswein Power Hand Controller to an electrical supply and the Recipro to Controller.
Set the slide Rheostat on the controller to “Low” or the “0” position. Put the Controller Main
Switch to the “ON” position, which lights up a pilot light that indicates your Recipro is ready
to use.
To increase the speed of the Recipro handpiece, move the Slide Rheostat toward “High”
or “10” and the desired reciprocating frequency and begin working. When the work is com-
pleted, put the Main Switch to “OFF.”
To operate your Recipro by using the optional Variable-Speed Foot Rheostat or optional On/
Off Foot Switch, please refer to the Power Hand Controller Instruction Manual for proper con-
nection. The handpiece will not reciprocate until the foot rheostat/switch is depressed. The
rheostat provides infinitely variable speed control; the switch only turns handpiece on and off
(operates at speed selected on control unit).
5. Precautions
A. For your personal safety, do not operate the Recipro handpiece with the cover removed.
Operation without the cover secured with the cover screw can cause foreign objects to
fall into the high-speed moving cam parts, causing bodily injury and handpiece damage.
B. Before operating your Recipro, be sure the desired tool is properly secured in the spindle
aperture.
C. Do not attempt to change tools or use the floating head feature while the handpiece is
operating.
D. During use, avoid pushing too hard on the work tool or exceeding torque capacity of the
Recipro motor.
E. After stoning operations with lubricants, prevent oil-abrasive slurry from entering the
handpiece by holding the Recipro with spindle pointed down.
F. When the Recipro is used against vertical walls of a workpiece, a hammering effect may
be felt in the handpiece and work tool. Although the Recipro has a spring-loaded cush-
ion to prevent damage caused by hammering or the restriction of stroke movements,
prolonged use of this nature can cause damage to the spindle, ball joint, metal bearings
and work tool.
G. Applications in which a sharp work tool strikes the surface of a workpiece should be
avoided.
H. Whenever possible, avoid using the Recipro in high humidity.
I. Always disconnect the Recipro from the Controller by the plug, not the cord.
J. Under normal circumstances, the Recipro handpiece will not overheat. If your Recipro
does overheat, please contact the Gesswein Repair Department.
6. Maintenance
Lubrication
It is necessary to lubricate the Recipro head assembly parts engaged in reciprocating
action. Lubrication should be scheduled for this portion of your Recipro once for each
eight hours of use.
The Recipro must periodically receive two small drops of oil. Lubrication is done through the
Lubrication Hole after removal of the small screw (part #103 – see p. 8-9 for parts drawing)
located in the top-front of the handpiece body. Two drops of light machine oil like the Spindle
Oil provided with the Recipro is sufficient to keep the spindle assembly working smoothly.
Cleaning
With prolonged use of the Recipro handpiece, oil, abrasives and dust from the workplace
atmosphere are likely to accumulate around and in the spindle aperture and under the
body cover. This accumulation could cause malfunction and damage to moving compo-
nents if not removed.
To remove the dirt from under the body cover, use a dry brush or a detergent-moistened
cloth. Periodically clean the spindle aperture with a cotton swab. Do not use paint thinner
or alcohol as a cleaner.
When the external surfaces of your handpiece become dirty, wipe with a cloth slightly
saturated with neutral cleaning liquid. Again, do not use a volatile liquid such as paint
thinner or alcohol.

Safety Recommendations — Prolonged –use of vibrating or reciprocating tools may result
in vibration-induced circulation problems in the hands. Always follow safe operating procedures.
Using hand protection (i.e., insulated gloves) and taking frequent breaks can help minimize but
not guarantee against injury. Operating these types of tools in cold weather or with a tight grip will
reduce the period of operation before risking potential injury. Individuals with a tendency to suffer
from poor circulation, frequently cold fingers or itchy hands should closely monitor the condition
of their hands. If symptoms appear, seek medical advice immediately.
Component Selection:
•PH3 controller
•Six motors (three high torque,
two standard, and one high speed)
•A selection of 8 heads
•Two reciprocating profilers
•One side-to-side profiler
•Belt Sander
Controllers and handpieces combine to create the most versatile finishing system in the
industry, offering rotary, profiling and belt sanding action.
