1. First use of machine
When you use the machine for the first time “new out of the box”, there are some items to think of.
irst you should install some new parts in the machine and there are some subjects to think of when
using the machine:
•irst you find some fuses. You should install one fuse in the round fuseholder at the machine
panel. Install this after you are sure that no high power (110/220V) cable is connected to the
machine! irst turn (left) the fuse holder from the machine panel, then put the fuse in the
holder and turn the holder inside the machine panel again.
•The remote control (RC) works by 2x 1.5V batteries. These should first installed into the
RC. Open the battery space of the RC and put the batteries in the right way. Then close the
RC again.
•When you want to use the machine with the internal battery and you don't use the machine
at 220V with the power cable, you should assure that the internal battery is fully charged. To
do this, you should connect the round charger cable to the machine panel and the other
connector to the 110/220V. The machine could be turned off by doing this (AC/DC button in
middle). When the battery of the machine is still charging, the led on the charger is red, it
will turn into green when the battery is charged. You also hear the cooling in the charger
turning when it is still charging.
•When the remote control is turned “ON”, the batteries will slowly be empty after some time,
even when the RC isn't used during that period. When you finished using the ball machine,
turn off the RC by pressing the “Power button” for about 3 seconds.
•When you use the ball machine with the internal battery, you need to put the “Power button”
on the machine panel on “DC”. When using the machine on 220V, you need to switch the
machine on “AC”. After usage, turn of the machine by turning the Power switch to the
middle.
•When using the machine with the battery power, you should switch the “Power button” to
“DC”. When using the machine at 220V, the 220V cable should be connected to a 220V
socket at the tenniscourt, the “Power button” should then be switched to “AC”. After using
the machine, you should turn off the machine again by putting the Power button to the
middle position. The machine show a light when turning on the machine, either on DC or
AC.
•The ball bucket could easily be put upside down on the machine by moving the handle
through the rectangle hole of the ball bucket.
•When the Power has been set the right way and the power lamp is lighting, the Remote
Control (RC) could be turned on (press about 3 secs the power button on the RC), the RC
then show some values in blocks at the speed, frequency and some settings on the display of
the RC. Don't stand before the machine (the side where the balls will be shot out of the
machine) when the power has been turned on. When pressing the “>/||” button of the RC, the

shooting wheels will start turning and the machine automatically will start shooting after
about 3 seconds. Press again the “>/||” button to stop the machine.
•The 2 front feet, at the bottom of the machine, will be responsible for the right angle of the
machine. Even though it is not right to change the feet many times and the factory set the
best angle already in the factory, it is possible to make small changes in the angle of the
machine by turning the 2 feet some. The right angle is dependant from the preferable speed
of the balls and the type of balls. You can do this by holding the screw at the inside of the
machine with a wrench (nr 17, through the shooting hole) while turning the foot. or
example high level players like to shoot the balls at high speed and then it is preferable to
shoot just close over the net so the ball is shot inside the lines. More lower level players
might want to shoot at lower speed some higher over the net. The angle could easily be
changed by using the “lob-foot” which is in the middle under the machine, in-between the 2
front feet.
•You can turn on the remote control before turning on the machine. When you press a button
on the RC, all the settings are sent from the RC to the ball machine. This makes it easy to
first set the right setting on the RC and then turn on shooting on the machine, the machine
has then immediately the right location(s), the speed and the frequency for the balls.

2. The different functions of the machine
The machine has several functions for shooting the balls in different ways:
•The spin (topspin of slice)
•At different speed
•At different positions on the tenniscourt:
1. ixed position, the horizontal (3 positions) and vertical positions (2 positions) could be set
preferable.
2. At 2 different depths (“high/low”).
3. Horizontal at 2-line or 3-line (2 or 3 fixed positions) or vertical at 2 positions or horizontal
and vertical together.
4. Random, at 3 horizontal and 2 vertical positions.
5. Cross, where 2 balls are shot at 2 cross positions. Always one ball is shot short and one ball
is shot deep, both at different horizontal positions. There are 6 combinaltions of the 2 balls.

1. Fixed position
The ball could be shot at one position (Horizontal: Left, Middle, Right). This position could be set
with the “<” and “>” buttons on the Remote Control. The vertical position could be set short or
deep (by pressing “^” (deep) and “v” (short) buttons) but you can also set the position much higher
(lobs) but this is a bit more difficult:
1. Set the machine on a ixed Deep position (“ ” and then “^”), the display of the RC display a
“.” on the deep location.
2. Press the “High/Low” button, the display of the RC displays the “:”. The machine moves
now from short to deep position and at both locations a ball will be shot. Then the shooting
system (2 wheels) move to the highest (lob) position but don't shoot a ball there. Even
though, you can lock the preferred height when pressing “ ” during the movement.
3. After you locked the height, you can move the horizontal position with the “<” and “>”
buttons.

2. Depths
The machine can shoot at 2 different depths on the court (“High/low”). The horizontal position
(Left, Middle or Right) stay the same then. To let the machine also vary with the horizontal
position, you should use the “random function”.
To let the machine shoot at 2 different depths, you do:
1. Press the “High/low” button, the machine shoot balls to the left side (for right-handed
people: backhand) at 2 depths.
2. Press again “High/low” to shoot in the middle at 2 depths.
3. Press again “High/low” to shoot at the right side (for right-handed people: forehand).
4. Press again “High/low” to shoot at the left side again.
To stop shooting at 2 depths, press “ ” again.

3. 2-line and 3-line
The machine can shoot the ball at 2 or 3 horizontal positions. The 2-line could be used for 2 (groups
of) players to alternately get a ball at exact the same positions of the groups. When the player of the
left group hit the ball, the machine move to the right group and shoot the ball. The player at the left
group could then be ready for the next ball or move to the end of the queue again and the next
player can make ready to hit the next ball.
When using 3-line, the ball will be shot Left, Middle, Right, Middle, Left, etc. This means that the
Middle position gets more balls than the other positions, which is normally not the purpose.
Therefore the 3-line is more useful for 1 player that get the ball at 3 positions over the whole width
of the court.
With both functions (2-line and 3-line), you can choose if the balls should be shot short or deep.
Push the “Horizontal” button (see below for how many times) for the next functions:
1. 3-line short
2. 3-line deep
3. 2-line short
4. 2-line deep
Press “ ” to stop the 2-line/3-line.

4. andom balls
The machine can shoot the balls at random horizontal positions at the court or at 2 vertical positions
(2 depths) as well.
1. To let the machine shoot random horizontally and vertically, press the “Random” button
once. The display shows 6 points at the display.
2. To let the machine shoot random only horizontally, press “Random” again (after nr 1). The
display now show 6 blinking points. Attention, because you let the vertical movement now
stop to shoot at only one vertical position, it's important at which moment you press
“Random”. If the machine shoot at one of the 2 vertical positions/distances, the machine will
keep on shooting at this vertical position and only vary the horizontal position. When
varying in vertical positions, the shooting wheel moves first to the highest (lob) position
before moving to the shortest position. When you press on the “Random” button during this
movement, the machine will stop shooting. Normally this is not the purpose. When you only
want to move randomly horizontal, you should press the “Random” button when the vertical
position is one of the 2 distances (short or deep). If you pressed the wrong moment, you
should start at (1) “Random” again.

5. Cross balls
The machine could shoot 2 cross balls at 2 different positions (skew). There are 6 different
combinations of playing the 2 balls, the number of pressing “Cross” gives a different combination:
1. Right short, Left deep
2. Left short, Middle deep
3. Middle short, Right deep
4. Right short, Middle deep
5. Middle short, Left deep
6. Left short, Right deep
To stop the cross balls, press “ ” button.

3. Speed, Frequency, Topspin and Slice balls
All trainings, which could be set on the ball machine, can be changed for the speed. Also, just like a
tennis player, the ball machine can hit the balls with less/more speed or with
topspin/underspin(slice). The spin has a fixed speed, less topspin let the ball hit the ground more
deep and more topsin let the ball hit the ground more close to the net. The speed and
topspin/underspin couldn't be mixed together. When changing the speed, during topspin/underspin,
the topspin/underspin will be stopped.
