SAFETY PRECAUTIONS
The SENSOR stringing machine has been designed to provide a reliable and perfectly safe
service. However, it could become a potential source of danger in the event of any incorrect
or poor maintenance.
In this manual, the paragraphs concerning safety are therefore drawn to your attention by
the following symbols:
Warning of a risk of serious personal injury.
BE CAREFUL: Risk of damaging the machine.
It is very important that operators should be familiar with the functioning of any
controls on the machine and be aware of its capacities and limits. They must
strictly comply with the instructions for use and any safety precautions indicated
in this manual.

INSTALLATION
♦ Positioning
Place the machine 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.
9
♦ Assembling
BE CAREFUL: because of the weight of the machine and its support post, any operations
of installation, assembly and adjustment must strictly be carried out by
2 people.
Place the support post in the required position (1).
Hold the stringing machine perpendicular to the fixing plate (2), making sure that the
interlocking elements are aligned. Place the machine on the plate and swivel it round by
90° so that the power cable is on the same side as the power socket.
1
Tighten the 4 fixing screws (3) with the size-5 Allen key.
To obtain the most comfortable and best-adapted
working height for stringing, loosen the handle on the
support post whilst holding up the machine (4). Move the
machine up or down until the required height is obtained
and then lock the handle again.
NB: the handle lever can be repositioned. Release it by
pulling, then move it to the required position.

♦ 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 (next)
Place the rack 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.
3
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 = 1.25 A T
220 V and 240 V fuses = 0.63 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.
12
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 shortcircuiting 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: Never insert any objects into the orifices around the turntable.
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.
13
♦ Menus and control panel
The control panel allows you to communicate with the machine. It has a liquid crystal
display screen with one 16-character line and 3 selection keys. The control panel allows you
to change the user settings on the machine and 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 3 keys on the control panel you can shift between the various menus and change
the options or values associated with them 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.
Control panel messages
The digital screen displays 3 types of information:
- status messages that keep you constantly informed of the machine's status when in
use,
- programmable menus allowing you to change option or modify the user settings,
- machine configuration messages (read only).

ACCESS TO USER MODE
♦ Positioning the racket
The SENSOR stringing machine is designed to take all types of rackets, even oversized ones.
BE CAREFUL: the racket locking system is designed to hold it in position and to prevent
distortion when stringing. Any over-tightening of the arms and billiards may
distort the racket and change the tension after stringing.
Position the racket according to the symbols
marked on the post.
Hold the racket by its handle with one hand,
and with the other turn the billiard control
knob (on the side of the racket throat) until
you bring the V-shaped pad of the billiard
into contact, between 2 holes and over the
positioning symbol marked inside the racket.
Turn the control knobs of the arms to bring
the pads into contact with the outside of the
racket. Make sure the racket is more or less
centred between the arm pads, then tighten
the arms slightly.
Turn the billiard control knob (on the side of the racket head) until you bring the
V-shaped pad of the billiard into contact, between 2 holes and in line with the first
billiard. Tighten the billiard slightly.
♦ Adjusting the clamp
The gap between the jaws should be adapted to the gauge of the string that is used. This
can be adjusted by turning the wheel as follows:
- thread a string between the jaws of the
clamp,
- activate the locking lever to tighten the
string between the jaws. If any resistance
stops it from locking, that means the gap is
not wide enough. Extend it by loosening
the wheel,
- pull on the string by hand and it should not
slide between the jaws. If this is not the
case, reduce the gap by tightening the
wheel.
BE CAREFUL: adjust the clamp gap to secure the string properly without crushing it, as
this would cause distortion and cracking.
23
♦ String tensioning
Once the racket has been properly installed and the clamp(s) adjusted, refer to the stringing
recommendations of the racket manufacturer and enter the tension value of the string
(TENSION) on the control panel.
To tension the string, thread it through the
pulling unit. At this point you should make a
precise movement: bring the string towards
you, and without letting it go, lightly touch
the "cycle start" button. This precise
movement is something you should get used
to very quickly.
After the pulling head is activated, the pulling
unit closes itself over the string. Let go of the
string. When the required tension is reached,
use the 3-tooth clamp to maintain the
tension of the stretched string. Lightly touch
the "cycle start" button again. The pulling
head will return to its initial position and the
pulling unit will open up and release the
string.
When the pulling head arrives at its end of travel
without the tension being reached, the buzzer
goes off to indicate that the tension is not
correct.
NB: the measuring system on your SENSOR stringing machine is automatically adapted to
the elasticity of the string (gut, synthetic, Kevlar
®
, etc.).
24
Clamp-holding system
With the clamp-holder you can easily position
the 3-tooth clamp at any point on the racket by
sliding it over the circular turntable.
During the stringing process, in order to keep
the string pulled, you should:
- slide the clamp-holder over the turntable to
position it under the string that you wish to
keep pulled,
- tighten the string using the locking lever of
the 3-tooth clamp (1),
- fasten the clamp-holder onto the turntable
by pushing down the locking handle (2).
To release the clamp-holder, loosen the
string by lifting the locking lever and let the
clamp drop. You can also release the clampholder by lifting the locking handle. To make
it easier to move, hold it by the base of the
clamp support barrel.
1
2
♦ Removing the racket
Always start by loosening the billiards before opening the arms. After releasing the racket,
unscrew the billiards completely so that you can easily insert the next racket.
♦ Turntable braking system
The locking button on the circular turntable can be used to immobilise it during rotation. You
will find this function useful when tightening the knots and tidying up the strings after you
have finished stringing.
25
TROUBLESHOOTING
At power up, the digital display does not light up
Make sure the power cable is properly connected to the machine
and to a mains socket.
Press the "cycle start" button:
- if the pulling arm moves, call your BABOLAT After-Sales
Service Centre,
- if the pulling arm does not move, check the fuses and replace
them if necessary (see paragraph "Changing voltage or
fuses").
At power up, the digital display lights up but the pulling arm does not move
after the "cycle start" button is pressed
Turn off the machine, wait 30 seconds and turn it back on.
If the problem continues, go to the "check" menu (see paragraph
"Using the control panel"), note down the values displayed and
the serial number of the machine, then call your BABOLAT AfterSales Service Centre.
During the stringing process, the clamp-holder malfunctions or does not
unlock
Call your BABOLAT After-Sales Service Centre and if the problem
cannot be solved you will need to replace the circular turntable
(see paragraph "Replacing the circular turntable").
♦ Replacing the circular turntable
The turntable is fixed by 3 screws placed at 120°. The screws can be reached through the
hole, intended for this purpose, under the machine.
Turn the circular turntable by hand to position the posts perpendicular to the line of the
pulling head, with the "racket throat" positioning symbol on the side nearest to you.
Loosen the first screw using the size-6 Allen key: it will remain captive.
Rotate the turntable clockwise by 120°, loosen the second screw and do the same for
the third.
26
Rotate the turntable again by 120° to bring it
back to its initial position and lock the
rotating turntable by tightening the locking
button.
Lift up the turntable and remove it from its
central pivot.
Replace it with the new turntable, making
sure the interlocking elements are lined up.
For re-assembly, following the dismantling
procedure in the opposite order.
MAINTENANCE
Make sure the stringing machine is always turned off before cleaning
it or servicing one of its components. Unplug the power cable from
the mains socket.
Never wash the machine using water, a hose or high-pressure
cleaning.
BE CAREFUL: never use corrosive products to clean your stringing machine.
Clean the housing of the machine regularly with alcohol at 90° only. Never use water,
detergents or acetone.
The circular turntable surface should be cleaned with alcohol every week to preserve the
optimal sliding capacities of the clamp-holder.
Remove the clamps, clean the clamp-holder rods and the inside of the clamp barrel with
a cloth soaked in alcohol, then lubricate them lightly with oil (sewing-machine type).
Replace the clamps on the clamp-holders and slide them about to spread the oil.
Clean the inside of the clamp teeth (depending on use, every day or once a week) with
a metallic brush, in order to avoid any clogging of the tungsten coating.
The Sensor pulling head does not require any particular servicing, apart from cleaning
once a year by passing a cloth soaked in alcohol between the articulated jaws of the
pulling unit.
Never oil the ball bearings on the pulling head.
