Notes before first use
We recommend pressureless tennis balls for use with the ball machine, as these retain their
bounce longer than balls with internal pressure when used with a ball machine. Balls with
pressure can also be used in principle.
The consistency of ball throws is dependent on the consistency of the tennis balls you use.
Tennis Tutor will throw slightly used tennis balls faster than it will throw older or worn tennis
balls. Consistent balls will produce consistent ball throws. A mixture of new and old balls will
produce inconsistent ball throws.
Inconsistent ball throws may also be caused by excess dirt and ink build-up on the ball
throwing wheels. Cleaning the ball throwing wheels as described in the section ‘Maintenance
and Cleaning’ will restore consistent performance.
IMPORTANT WARNINGS
DO NOT STAND IN FRONT OF BALL EJECTION OPENING.
DO NOT INSERT HANDS OR FOREIGN OBJECTS INTO THE MACHINE.
DO NOT OPERATE TENNIS TUTOR WHEN WET OR WITH WET BALLS
Operating the Tennis Tutor Plus Player ball machine
Take the connecting cable and plug the red plug of the cable into the red socket (marked
CHARGE) on the control panel of the ball machine.
Plug the black connector into the black socket to the left of the red socket. The other end of
the connection cable has two banana plug sockets. Please plug the cable of the battery into
the socket with the small red push button. Now the connection between the battery and the
ball machine is established. If you now press the Power ON switch, the machine will run.
Place the ball machine along the centre line of the court - i.e. in the middle. Position the ball
machine for faster balls at the baseline and for slower balls more towards the service line.
Switch the ball machine ON and set the control for the desired ball.
If you are using the ball distributor (OSCILLATOR), align the ball machine so that the balls are
evenly distributed on the left and right sides of the court.
Turn the ball machine OFF and wait for 5 seconds for the 10-second start-up delay to reset.
Turn the ball machine ON and move to your playing position.
TIP: The ball feed mechanism works best if you feed the balls into the basket from the front.
This reduces jamming.
Switch off the ball machine: Press Power (OFF) and pull out the black and red plugs above
the <Charge> label, please touch the plugs and do not pull on the plug's cable. Disconnect
the cable from the battery. It is best to place the cable in the small bag provided. Place the
battery in this bag as well.

The Reset button
1) A ball is stuck in the machine. Remove the ball before resetting the button. If you don’t
see the ball between the throwing wheels, look in the front corners of the machine.
2) The ball throwing wheels are excessively dirty or slick. This prevents the wheels from
properly grabbing the ball. Cleaning the ball throwing wheels as described in the section
‘Maintenance and Cleaning’ will restore proper performance.
3) The machine may need service. Do not repeatedly push the button if it continues to pop
out.
Control Panel
1) POWER - Pushing to the ON position begins a start-up time delay period of about 10
seconds before tennis balls are thrown.
2) BALL SPEED - Turning clockwise, from ‘1’ to ‘10’ increases the speed at which balls are
thrown.
3) ELEVATION - Pushing the UP arrow raises the ball trajectory, and pushing the DOWN
arrow lowers the trajectory. The elevation control automatically stops at both the highest and
lowest possible trajectories. It is best to move UP to the desired trajectory. The position of the
elevation setting is shown on the bar graph display.
4) BALL FEED - Turning clockwise increases the frequency of ball throws from one ball every
10 seconds at a setting of ‘1’, to one ball every 1-1/2 seconds at ‘10’.
5) SPIN - Turning clockwise from ‘flat’ increases the amount of topsin,
turning counter-clockwise from ‘flat’ increases the amount of underspin.
6) OSCILLATOR - Push the switch ‘ON’ for random oscillation.
7) REMOTE - For models with remote control only. See the section ‘Remote Control’.
8) BATTERY CHARGE JACK - The connection cable to the lithium-ion battery is connected
to the two sockets.
9) RESET BUTTON - See the section ‘Reset Button’.
PLAYER MODE
Set the Tennis Tutor at the center of the baseline. Before initiating PLAYER MODE™ it is best
to stop shooting balls by pressing the START/STOP button of the INTERVAL control.
Make sure the machine is set to move evenly to both the forehand and backhand sides. Push
the OFF/[CENTER] button. This will set the oscillator to the center position. Then physically
align the front edge of the machine parallel to the baseline.
Push either the BEGINNER, INTERMEDIATE, or ADVANCED buttons, and
PLAYER MODE™ automatically picks an appropriate interval, elevation, speed, and spin, then
changes both the side-to-side position and the depth of shots just like you were playing
someone of that ability. Restart ball throws by pushing the START/STOP button or by
pressing the BALL FEED button on the Remote Control.
The first ball thrown after pushing a PLAYER MODE™ button will be up the middle and to the
deepest position. Use the first throw as a reference for making any changes you desire in the
elevation, speed, or spin settings. Any changes you make will be saved even if you turn the
Tennis Tutor off, so the next time you practice you can resume with the same settings. Any

4
time you press a PLAYER MODE™ button it will delete any changes and revert to the default
settings.
The side-to-side position and depth of each shot are computer-programmed to simulate the
shot patterns of real players. The BEGINNER setting will not shoot any balls wide to the
corners, but will vary the depth of shot more than will the INTERMEDIATE and ADVANCED
settings. The INTERMEDIATE and ADVANCED settings will throw balls across the entire
width of the court, but more balls will be toward the center just like in a real match. The
ADVANCED setting has the most side-to-side variation, but the least variation in depth.
The Remote Control
The Multi-Function remote transmitter controls all functions of
the Plus Player model. Press the appropriate button on the
transmitter to adjust the various settings, just as you would on
the control panel of the machine. The machine will “beep” to
confirm each stage of adjustment.
NOTE: Tennis Tutor still draws power from the battery when the
ball feed is turned off with the remote control. To preserve the
battery charge turn Tennis Tutor ‘OFF’ when you are picking up
tennis balls.
Transporting the Tennis Tutor Ballmachine
Please remove all balls and close the four flaps of the ball container carefully so as not
to break off the small axles of the flaps.
To transport Tennis Tutor over flat terrain extend the towing bar and tow as shown.
To transport it over rough terrain or stairs lift it by the carrying handle.
To lift Tennis Tutor into the trunk of a car use two hands as shown.
Place one hand on the towing bar and one hand under the upper lip
of the ball ejection opening. Make sure the towing bar is securely in
place before lifting.
Do not store Tennis Tutor in the trunk of a car. Heat build-up inside a
car trunk can reach 180 degrees, which may damage your machine.

Charging the battery
The charger supplied has a cable with a banana plug socket. The battery has a cable with a
banana plug. Please connect both. If you now plug the cable of the charger into a socket
(220V), the charging process will begin. On the back of the charger you will see a dimly lit
diode. This lights up red at the beginning if the battery is not 100% fully charged. The diode
switches to green when the battery is 100% charged.
Checklist for optimal use of the lithium-ion battery:
Unnecessarily long charging should be avoided. Although the charger has built-in overcharge
protection, it should still be removed from the machine when the green diode on the charger
is lit.
•Use in the field between 20° and 60° C
•Charge at 0°to 45° C and at the latest when the ball throws become significantly
shorter. Deep discharging should be avoided at all costs.
•Storage between 10°and 20° C (dry) and a medium charge level (if stored for a longer
period, recharge a little every 6 months).
Maintenance and cleaning
We recommend that you clean the ball caster wheels at least every 100 operating hours in
order to
to avoid inconsistent ball throws caused by excessive dirt and ink deposits on the wheels.
Clean the ball throwing wheels only when the ball machine is switched off. Rub coarse
sandpaper (grit 40 to 60) over the ball ejection wheels through the ball ejection opening to
remove dirt and ink build-up. Sand the entire circumference of each wheel. Use enough
pressure to actually roughen the rubber surface of the wheels. The wheels should feel rough
after sanding.
Use a slightly damp cloth to clean the casing. Do not use chemical or abrasive cleaners. Use
a hoover to remove dirt from the inside of the unit. Do not use compressed air.
