Babolat SENSOR EXPERT User manual

INTRODUCTION
You have recently purchased a BABOLAT SENSOR EXPERT stringing machine - thank you for
making the right choice! This manual has been written specially to help you get used to the
way the machine works and to make sure that it meets your expectations. Please READ
THESE INSTRUCTIONS CAREFULLY to give yourself a good idea of the precautions to be
taken when you use your new machine and to look after it in the best possible way.
Keep this manual to hand so that you can consult it at any time, and make sure that it
stays with the machine if ever lent or sold.
A VHS video cassette comes with your SENSOR EXPERT stringing machine. We suggest you
to watch it in addition to reading this manual, so that you will have a good understanding of
the main operations for setting up and using the machine, as well as the actions required for
stringing.
This machine is intended for professional use and is designed for the stringing of all types of
rackets - tennis, badminton, squash, etc. - using strings made of synthetic materials or
natural gut. It must be used by operators who are qualified and well-versed in the operating
rules and safety instructions set out in this manual.
Your SENSOR EXPERT stringing machine is "CE" certified and is in conformity with machine
directive 89/392/EC. We will not assume liability if any alterations are made to the machine
without our authorisation, thus undermining the safety conditions and invalidating any
warranty clauses.
We also wish to draw your attention to the fact that the use of accessories or products other
than those recommended by BABOLAT may present risks for which we will not be liable.
As we want you to make the most of the latest technology and new equipment, as well as to
benefit from our experience, our machines may undergo technical or design changes. As a
result, some of the features and information in this manual may be changed without prior
notice and without any obligation to up-date it.
Should you encounter any problems or have any questions about your SENSOR EXPERT
stringing machine, please do not hesitate to contact your nearest BABOLAT After-Sales
Service Centre.

ON RECEPTION
♦ Recommendations
Before opening the boxes, make sure that there is no apparent damage. If you notice that
the packaging is not in perfect condition, make sure that a reservation to this effect is
recorded on the carrier's delivery docket so that your rights are protected. Also verify that
the specification of the machine corresponds to your order, by reading the label attached to
the outside of the boxes.
♦ Unpacking the machine
We have designed packaging that is specially adapted to the transporting of your machine.
We advise you to keep it carefully because it should be re-used for storage purposes or if
ever you need to return it to the manufacturer.
We will not be liable for any damage caused to machines that are sent back
without their original packaging.

INSTALLATION
♦ Positioning
 Place the equipped machine cupboard on a flat surface near an electricity supply and in
a space that is sufficiently open to give the operator room to move, allowing for a
minimum safety area of 800 mm around the machine.
The following conditions should be respected for the environment of the workstation:
- temperature: 10 to 35 °C,
- relative humidity: 30 to 70 %,
- minimum lighting: 300 lux.
Make sure you protect the machine against splashes of water and
never leave it in the rain.
10

♦ Assembling
BE CAREFUL: because of the weight of the machine and its cupboard, any operations of
installation, assembly and adjustment must strictly be carried out by
2 people.
 Place the cupboard in the required position.
 On the side of the cupboard, remove the
BABOLAT decorative plate (1), by loosening
the 6 fixing screws with a star screwdriver
(not supplied).
 Place the stringing machine on its cupboard,
perpendicular to the latter.
 Loosen and remove the transport screw (2)
and keep it in a safe place with the
packaging.
BE CAREFUL: whenever you move the
machine, this screw should be
replaced completely in order to
avoid the accidental rotation of
the turntable during the
transport, especially if you
return your machine. Failure to
comply with this instruction may
limit the application of the
warranty conditions.
 Position the machine above its cupboard by
lifting it, on one side by the base of the rack,
and on the other by the 2 posts (3).
Never lift the machine by holding onto the
profiled arms or the Sensor head.
 Slot the machine into its cupboard.
 Plug in the power cable under the machine (4).
 Replace the BABOLAT decorative plate.

♦ Connecting to power supply
Make sure you always connect the machine up to an earthed mains
socket.
Extension cables should be carefully chosen, assembled and
maintained. Your safety will obviously be protected if the insulation
is in good condition. Cables should be inspected on a regular basis
and replaced, rather than repaired, if found to be faulty. Adapt any
electrical extension lengths and sections depending on the work at
hand.
BE CAREFUL: make sure that the voltage indicated on the identification plate corresponds
to that of the local grid.
Powering-up
 Plug the power cable into a properly earthed mains socket.
 Switch the machine on using the On/Off switch and a welcome message will
appear on the display screen. If this is not the case, please refer to the
section "TROUBLESHOOTING".
Changing voltage or fuses
For this job you will need to remove the rack
from the machine.
 Turn off the machine.
 Remove the BABOLAT decorative plate on
the side of the cupboard.
 Remove the power cable from the mains.
 Unplug the right-angle plug on the power
cable from the machine.
 Loosen the 2 fixing screws (1) by two turns,
using the size-4 Allen key.
 Remove the rack from the machine by pulling
on the lower handle (2).
 Place it on a table to provide free access to
the lower part.

 Remove the fuse-holder located under the
rack (3) near the power socket, using a flat
screwdriver.
Changing voltage
 Remove the voltage selector, then switch it to the required voltage.
 Then change the two fuses depending on the new voltage.
100 V and 120 V fuses = 3.15 A T
220 V and 240 V fuses = 1.6 A T
In case of doubt, call the BABOLAT After-Sales Service Centre.
Changing fuses
Type of fuse: HPC 5x20 mm ceramic
BE CAREFUL: in the event of a problem, you should change both fuses at the same time.
The warranty will be invalidated by the use of any fuses other than those
recommended by BABOLAT.

USING THE MACHINE
♦ Warnings
BABOLAT will not be liable for any direct or indirect damage caused by incorrect
installation, poor maintenance, alterations or improper usage. We will also be
cleared of liability in the event of any failure to comply with standard
requirements for the prevention of accidents and fire or for the safety of
electrical installations.
Never open a stringing machine without being authorised by BABOLAT.
Never apply any varnish or paint to the string above the machine, as stains from
these products may cause permanent damage to the housing and mechanical
parts.
Any failure to comply with these last two clauses will render the warranty
invalid.
To turn the stringing machine on or off, do not use the power cable.
Press the On/Off switch to avoid any risk of electrocution or short-
circuiting due to poor contacts.
Never move or open the stringing machine without unplugging it
first.
Never let the machine be used by children or persons not familiar
with the instructions. Make sure that nobody enters the 800-mm
safety area around the machine whilst it is in use.
Never leave your workstation before making sure that you have
taken the precaution of putting it in the shield position ("shield"
menu on control panel) or turning it off (at On/Off switch).
BE CAREFUL: Your stringing machine has been adjusted in the factory using precision
instruments. Except in the case of accident, the factory adjustments should
not be altered throughout the life of the machine, otherwise you will have
to return the rack to the manufacturer.

♦ The control panel
The control panel allows you to communicate with the machine. It has a liquid crystal
display screen with 4 lines of 40 characters. Using its 4 selection keys and 3 scrolling keys,
the control panel allows you to change the user settings on the machine and to view the
current values to find out its status. The factory settings and those entered by the user are
stored in an EEPROM memory so that they are not deleted when the machine is turned off.
Using the keys on the control panel you can shift between the various screens and change
the options or values associated with the menus in order to adapt the machine's functions to
your demands.
There are 3 ways of changing the machine data:
- by activating/deactivating a setting,
- by changing a digital setting,
- by selecting an option on a menu.
It is very straightforward to use the control panel and change the options or values assigned
to the menus. Read the following paragraphs carefully and try it out for yourself. Do not
worry about making a mistake as there is no danger for the machine - you will just need to
start again from scratch.
