Thank you for purchasing a SPINSHOT Plus-2 tennis ball machine. This
manual contains important information concerning the proper use and
care of your ball machine. Please read the owners manual completely
before operating your machine.
What Tennis Balls to Use
Normal pressurized tennis balls or pressureless balls can be used in your
Spinshot tennis ball machine. Pressureless balls are recommended for their
longer life and more consistent bounce compared to pressurized balls.
The consistency of ball throws will depend on the consistency of the tennis
balls being used. A mixture of new and old balls will produce inconsistent
throws. Inconsistent ball throws can also be caused by excess dirt and ink
build up on throwing wheels. Cleaning the throwing wheels as described in
the Maintenance and Cleaning section will restore a consistent performance.
Important Warnings
Do not reach or look into the ball exit hole without turning the main power
off, and only after both wheels come to a complete stop.
Do not stand closer than 10 meters in front of the ball machine when the
power is on.
Do not place balls or foreign objects into the ball hopper while the feeder
tray is moving. It could cause jam and damage the feeder motor.
Overloading of balls into the ball hopper may result in a jam of the feeder.
No more than 120 balls should be put inside the ball hopper.
Do not use your machine while it is raining. Do not use wet tennis balls.

Section 2: Operating Your Tennis Ball Machine
Your tennis ball machine can be operated via the Control Panel situated
on the side of the machine, the Drill Maker App on your phone, the
Spinshot Remote Watch (sold separately).
Control Panel
POWER SWITCH
The power switch is used to turn the
machine on and off. After the machine
is powered on, both horizontal and
vertical motors will perform a functional
initialization for proper function of the
machine. The current battery voltage will be
displayed on the LCD screen.
Put the machine at the center of the
baseline and adjust to face the center of
the court to ensure the machine sweeps the
balls evenly across the court.
The machine will default to the last mode
set. To start the ball feed, press the PLAY
button and then press the button of the
chosen program. To stop the ball feed press
the PLAY button.
If at anytime the machine malfunctions, turn off the power switch to reset
the machine’s control logic. In most circumstances, the improper working of
the machine is caused by low battery voltage. In this case, please recharge
your battery to resume normal operation.

MOTOR T and B TRIP SWITCHES
The MOTOR switches protect the electronics and motors. When activated,
the switch pops out approximately 6 mm. In the event the switch is
activated, turn off the power and push the switch back in. Once the
throwing wheels have stopped moving, check for any balls jammed inside
the machine and remove them. Turn the power back on to resume normal
operation.
The activation of the motor switch can be caused by excessively dirty or slick
ball throwing wheels, which can prevent the wheels from properly gripping
the balls. Cleaning the ball throwing wheels as described in the Maintenance
and Cleaning section will restore proper performance.

To adjust the spin of the ball, press the SPIN button then press the UP or
DOWN buttons to adjust the spin level.
Select a negative value to produce backspin or slice, or a positive value to
create topspin. A setting of 0 will serve a at shot. Spin ranges from -9 (max
backspin) to 9 (max topspin).
A high level of either topspin or backspin will slow the ball speed. To
increase ball speed reduce the amount of spin on the ball.
It is possible to adjust the SPIN value while the machine is playing and it will
take effect immediately.
HEIGHT BUTTON
To adjust the height (trajectory) of the ball, press the HEIGHT button then
press the UP or DOWN buttons to adjust the height level.
The height setting will control the ball height when the machine is not
running in the vertical oscillation mode. The height setting will be displayed

This button is used only in the vertical oscillation modes. In the vertical
oscillation modes, the machine is serving balls at two height levels dened
by the h1 and h2 settings.
Press the h1-h2 button once to set the h1 level. Press the h1-h2 button
again to set the h2 level. This setting is only effective when the machine is
set on a vertical oscillation mode (horizontal vertical oscillation mode, 2-line
vertical oscillation mode or vertical oscillation mode).
w1-w2 BUTTON
This button is only used for horizontal 2-line oscillation modes (2-line
oscillation and 2-line vertical oscillation). In the horizontal 2-line oscillation
modes, the machine is serving balls at two widths dened by the w1 and w2
settings.
Press the w1-w2 button once to set the w1 placement. Press the w1-w2
button again to set the w2 placement.
The width ranges between 1 (far right of the court) and 20 (far left of the
court).
Oscillation Modes
Besides the programmable drills, the plus-2 model can support various
oscillation modes, or the combination of oscillation modes. Overall there are
ve types of oscillation:
1: Random Horizontal Oscillation
2: 2-Line Oscillation
3: Vertical Oscillation
4: Random Horizontal and Vertical Oscillation
5: 2-Line Horizontal and Vertical Oscillation
RANDOM = Random Horizontal Oscillation
In this mode the machine serves balls randomly across the width of the
court. Ball speed, height, spin and feed rate can be adjusted for the random
oscillation mode.
5

2-LINE = 2-Line Oscillation
The 2-Line oscillation setting serves balls to two preset locations on the
court allowing a user to practice alternating forehand and backhand shots.
Placement of these alternating shots can be dened by using the w1-w2
setting as described in the w1-w2 button section.
After the machine has been set to the 2-line oscillation mode, the user can
press VERTICAL to make the machine set to a 2-LINE HORIZONTAL AND
VERTICAL OSCILLATION.
VERTICAL = Vertical Oscillation
The vertical oscillation mode serves a combination of high balls and low
balls. The machine will serve balls at two height levels dened by the h1 and
h2 settings.
If machine has been in the random horizontal oscillation mode, pressing
this button will set the machine to RANDOM HORIZONTAL AND VERTICAL
OSCILLATION mode. If the machine has been in 2-line oscillation mode,
pressing this button will set the machine to a 2-LINE HORIZONTAL AND
VERTICAL OSCILLATION mode.
In all vertical oscillation modes, pressing the SPEED button a second time
will set the speed level for the second height level (h2).
MANUAL = Manual Mode
Pressing the MANUAL button will set machine back to manual mode without
oscillations.
Spinshot Remote Watch
The remote watch can be used to start and stop the ball feed and select
drills. A long click (over two seconds) will start and stop the ball feed. A
short click of the button selects the drill number equivalent to the number of
clicks. ie, 2 clicks = Drill #2, 12 clicks = Drill #12.
The remote watch will enter sleep mode after 30 seconds of inactivity. When
the machine power is on, pressing the remote watch button to wake it up. If
the LED is not lit up on the remote please move closer to the machine and
check again.

Battery Charging
To extend the life of your battery please follow these guidelines.
• Charge the battery immediately after each use. Don’t leave your
battery in a at state for extended periods.
• Don’t leave the battery plugged into the charger too long after it is
fully charged.
Your battery will take 8 to 15 hours to be fully charged. The LED light on
the charger pack will turn green when the battery is fully charged. If LED
stays red, the charging process is still continuing. A fully charged battery will
provide approximately 2-3 hours of use. Higher ball speed requires more
power and therefore will drain the battery faster.
Battery Model
Plug the battery charger into a electrical outlet and then insert battery
charger cable into the socket labeled CHARGER on the control panel of your
machine.
Hybrid Power / Battery Model
Plug the battery charger into an
electrical outlet and then connect the
battery charger cable to the battery
cable port (as pictured).
Installing or Replacing
the Battery
If you need to install or replace your battery you can do so by opening the
battery cage. To access the battery cage please follow these steps:
1. Remove wheel that covers the access panel to the battery cage.
2. Unscrew the four screws of the access panel.
3. Connect the battery to the terminals inside the battery cage - connect
the red wire to the red terminal and the black wire to the black terminal
4. Insert the battery into the battery cage. Ensure you put the battery
terminals to the top left side when you insert the battery into the cage.
7

Static Electricity
It is possible that the action of the tennis balls rubbing against the throwing
wheels will cause a small static electric shock when you touch the control
panel. To eliminate this connect a wire from the control panel to the court
surface. Some machines have been tted with a small chain on the underside
of the base to ‘ground’ the machine and eliminate this issue.
Transporting and Storage
Remove all balls and close the ball hopper aps before transporting your
tennis ball machine. Store the machine in a clean, dry location. Never store
the machine in a vehicle where temperatures can be very high. Extreme
temperatures and conditions can affect the machine’s electronic board and
battery. Never store the machine outside. Exposure to rain and snow will
shorten the life of the machine.
Maintenance and Cleaning
Use a vacuum cleaner to clean dirt and debris from the inside of the
machine and in and around the black hopper tray. The build up of debris in
the hopper can cause excess wear on the feeder motor which powers the
spinning of the hopper tray. Shake off excess sand and dirt from the tennis
balls before putting them into the hopper.
To clean the exterior case, use a damp cloth. Do not use chemicals or
abrasive cleansers.
The use of compressed air for cleaning is not recommended.
Annual Maintenance
We recommend cleaning the ball throwing wheels every year or after
150 hours of use especially when the machine is not throwing the balls
consistently. Clean the ball throwing wheels only when the machine is
powered off. Firmly rub coarse sandpaper across the throwing wheels
through the ball ejection opening to remove the dirt and ink build-up. Sand
the entire circumference of each wheel and use enough pressure to rough-
up the rubber surface of the wheels.

are not covered by the warranty:
• Units damaged by accident, misuse, abuse, neglect
• Units modied by unauthorized personnel
• Units damaged during shipment
• Battery damage
Section 4: Warranty
13

Ball Speed
Topspin and Backspin
A high level of either topspin or backspin will slow the ball speed. To
increase ball speed reduce the amount of spin on the ball. A default speed
setting of 20 will be set for spin levels higher than 7.
Alternating Fast and Slow Shots
The serving wheels can speed up faster than they can slow down. If you
want to set quick shots followed by slow shots, please set long feed
intervals between shots to give the machine time to slow down, or add a
mid speed shot in between.
For example, if you want
Ball #1 speed = 19 (fast)
Ball #2 speed = 12 (medium)
Then set feed rate to around 4 which will take 6 seconds for the machine to
slow down and allow for slower second ball.
Or set ball #2 to speed = 1, which will then make the ball machine slow
down quicker.
Dirt and Ink Build Up on Throwing Wheels
Excess dirt and ink on the throwing wheels can cause slow and inconsistent
ball throws. See the Maintenance and Cleaning section for more details.
Ball Placement During Oscillation
Position the machine on the baseline to adjust the angle if the machine is
favoring one side more than the other. If there is a strong cross wind over
the court you may have to face the machine facing more towards the wind
direction to allow for strong wind affecting ball direction. Making these
adjustments will make the machine throw balls evenly across the court
during horizontal oscillation modes.
Section 5: Additional Information
14

Why does the reset button pop out and turn off the machine?
A ball jammed maybe inside the machine and is blocking the normal
operation of the service wheels. Do not use wet, or very soft tennis balls as
these will cause a jam.
My machine is battery powered. Can I upgrade it to support
main’s power?
Yes, you can change the battery to main’s power module. See http://www.
spinshotsports.com/power.html for more options.
Why does my machine always serve balls across the right side line,
when I set the horizontal position to 20?
Because you did not properly place the machine in the right direction. Turn
the machine slightly to the left direction should correct this problem.
After creating a new drill, will it be exactly the same next time I
use the same drill?
Yes, every time you use the drill you will get a consistent result if you use
the same batch of balls. Please don’t forget to charge the battery after each
use. A at battery can make the ball machine less powerful and impact the
consistancy of balls thrown.
I see from the website that a phone remote is an option. Will that
be an optional extra for the player model?
No, the phone remote feature is a standard part for the player model.
In Manual mode, can I adjust the horizontal direction?
Yes. After you press the Manual Mode button on the Dril Maker App, select
the Horz button to adjust the horizontal direction of the machine.
How can I adjust the setting to slow down the ball shots when I
apply random height settings?
When user set the HGHT level to R or 0, the machine will shoot balls in
random height angle, and the ball speed is not controllable by the user. The
only way user can adjust the ball speed is by adjusting the ball SPIN. The
higher spin level will make ball slower.
Section 6: FAQs
15

Why does the machine move on the court in use?
This could happen on some slippery courts when the external battery
option is used. When the battery is taken out of the machine, the machine
may be too light to be stable. It could move a little bit due to recoil when
the machine shoots out the balls. To keep it stable, it is suggested the user
either puts a weight in the battery cage, or hangs the battery or other
weight on towing handle to increase its weight.
What about the pre-programmed drills for the machine?
The SPINSHOT player machine comes with all drill buttons programmed in
the factory. The setting values are similar to the default values shown in the
phone remote app.
We do not publish the detailed setting values for default drills, as it is
strongly suggested that the user edit the drill settings and download them
to the ball machines to try out, and then create their own preferences. This
is most the important feature that the player machine has. Once the favorite
drill is created, the user can save it on the machine or on the phone for
future use.
Is there any resource that explains the drill programming?
Yes, you can nd some good video resources on YouTube explaining the
programming of the drills. Please visit the Product Support - Videos section
of our website for links to these vidoes.
Can two phones set up different drills to be used on the same
machine?
Yes, the user can edit and save favorite drills on different mobile phones and
download them to the SPINSHOT player machine when using the machine.
The machine will save the downloaded drill data to its memory and shoot
the balls accordingly. The user needs to manually download each drill as
required.
Why can’t I download and install the Drill Maker app for Android
from the SPINSHOT website?
Some preinstalled applications on Android phones may block the installation
of the app for safety reasons. Please temporarily disable such apps like
“LOOKOUT” to allow the installation of the drill maker app.
