1 INTRODUCTION
OBS11 presents a powerful new patented feature, revolutionising the way the swimmers start from
their blocks. Diving from the starting block with the body propelled by the knee at a 90° angle
drastically increases the explosiveness of the start. Physical tests undertaken by top level
swimmers showed faster races versus a standard block.
OSB11 starting blocks have been tested by world-class swimmers, who have helped to specify the
optimum angles of both the platform and the footrest for racing starts. Design research also applied
to the top surfaces, very comfortable yet rough enough to guarantee the swimmer a feeling of total
security. The length of the platform is extended to 74cm to accommodate to the new styles of start.
The diameter and position of the handgrips have also been carefully considered to respond to all
the requirements of different hand positions. A door at the back of the block allows easy access to
the interior to connect the cabling. .
OSB11 starting blocks benefit from a new design and an attractive color scheme.

2 INSTALLATION
2.1 Positioning of the OSB11 starting blocks
The OSB11 starting blocks are positioned according to the measures indicated: 400mm from the
swimming pool border (410mm with the OCP5 touchpad) to the front of the base.
The handle of the OSB11 must be aligned with the border of the touchpad (for example OCP5).
Are the touch plates missing or is the swimming pool too small with touchpads, align the OSB11
starting block with the border of the swimming pool.
The drilling oblong fixations permit a play of the block of +/-10mm; this permits a possible
correction of the alignment.

Swimming Pool as per
FINA regulations

Page 6 3454.504.02 Version 1.7
2.2 Fixation of the starting block
To ensure proper functioning of the OSB11 starting block system,
fixation must be absolutely rigid.
2.3 Drilling and mounting of the OSB11
For fix cabling, a hole with Ø120 - 122mm at 570mm away from the pool's border must be
foreseen in order to provide space for the cables (the gauge has a hole of Ø120mm).
Put the drilling gauge (1) on the border of the swimming pool and mark the 4 Ø5 holes of the
gauge with a Ø5 drill.
Drill the 4 holes respectively with drills 5, 10 and 16mm (2). Minimal depth: 90mm, maximal
depth: 95mm.
As per instruction manual 3393.505 "Preparing the drillings", push the pegs M8 (3) in the
16 holes and put the OSB11 starting block on the 4 fixation points.
Fix the base with the 4 screws M8 x 40 (5) and the 4 washers M8 (4).

platform, the buzzer (11) remains silent. If the buzzer (11) emits a sound, proceed as
described in paragraph 4.5.
4.2 Pressure sensitivity control
Press with the Dynamometer (12) against the middle of the platform (3). Read on the
Dynamometer (12) the pressure necessary to activate the buzzer (11). If the sensitivity is out of the
range of 13kg and 18kg, see paragraph 4.7.
4.3 Connection to the timing system
If a satisfactory result has been obtained in tests 4.1 and 4.2, connect the connection
cable (9) to the timing system.

4.4 Inspection
Every 6 months: check cable connections.
Once a year: check rigidity of block fixation.
4.5 Troubleshooting (detection of a short circuit)
If the buzzer (11) emits a sound while there is no pressure on the platform, proceed as follows:
- Unscrew the 4 nuts M8 (7) under the platform (3).
- Remove platform (3) and connect the buzzer (11) to the connection cable (9).
- Insert a screwdriver into the 2 holes of the lower frame (4) and unscrew each of the
adjustment screws (6) until they do not touch the contact head any more.
If the sound continues, verify if there is a short circuit on the cable or between the fixed and mobile
frame (mechanical or electrical connection).
4.6 Troubleshooting (no contact)
If the buzzer (11) does not emit a sound during the sensitivity adjustment, proceed as follows:
- Make sure that the platform and the RBD are correctly assembled; there must be a visible
movement (Paragraph 4.8).
- Make sure that the 2 adjustment screws are not too far apart.
4.7 Sensitivity adjustment
If the sensitivity is out of the range of 13kg and 18kg (as indicated in paragraph 4.2), make an
adjustment by proceeding as follows:
- Connect the buzzer.
- Insert a screwdriver in one of the holes of the lower frame (4) then screw the adjustment
screw (6), facet after facet of the hexagonal head until the buzzer emits a sound.
- Unscrew the adjustment screw by turning it 4 facets backwards (0,16mm/facet).
- Adjust the second screw in the same way.
- Make a test with the Dynamometer (12) by pushing or pulling the upper frame (4).
- If the measured pressure is higher than 18kg, continue screwing the screw in and test at
every facet.
- If pressure is lower than 13kg, unscrew and test at every facet.
It is recommended to proceed systematically with the adjustment to obtain a regular play between
the 2 contacts.

5 PREVENTION AND MAINTENANCE
Equipment installed in aquatic complex, often sealed with a high moisture level, require special attention in
regards to their maintenance. In fact, the stainless steel parts found on ladders, fences or swimming starting
blocks can have corrosion if they are not frequently cleaned.
Stainless steel is an excellent product that needs to be very clean to keep its stainless quality.
MAINTENANCE
When you receive your new equipment, it is important to establish a maintenance program to
avoid the stainless steel parts to deteriorate. Indeed, lack of maintenance can make the
chromium oxide film inefficient, which could cause corrosion on your equipment. A dirty
surface is the biggest ally of corrosion and your biggest enemy.
Dirt, grease and deposit left by users or by contaminated water deposit must be removed by cleaning the
surface with fresh water (do not use the pool’s water) and wiped, if possible, with a clean dry cloth.
A basic cleaning of the starting blocks’ inner and outer surfaces (without disassembling) must be done
regularly, preferably every week.
A thorough cleaning with removal of the top (see manual) must be done regularly, several times a
year, depending on the degree of contamination of the stainless steel. You must pay extra attention to
the RBD (Relay Break Detection) and the handles (backstroke ledge).
Concerning dismantling, it is imperative to use tools that are specially designed for stainless steel.
Applying a hydrophobic (insoluble in water) silicone type B 431 also increases the protection of the
sensitive areas of the OSB14 against corrosion.
A tube of this silicone is provided with each mounting set and must be used in case it is dispersed and
after each thorough cleaning or rehabilitation.
REMEDIATION
If your equipment is already showing significant dirt deposits, you need to get rid of them in
order that the oxygen from the air gets in contact with the chromium in the stainless steel to
form the protective chromium oxide film.
A thorough cleaning with fresh water should be sufficient. If some dirt remains, rub with a nylon pad
or a cotton cloth. Make sure the pad you use is not rough to prevent it damaging the protective film or the
aesthetic finish of the product.
After a thorough cleaning, clean the stainless steel with fresh water twice a week during a few months
and then decrease the frequency.
Never use a metal brush, steel wool, emery paper or any abrasive material to clean. Indeed, stainless
steel would be contaminated by a large quantity of undesirable particles which inevitably would cause
rust stains.

REMINDER
A weekly basic cleaning is required.
A thorough cleaning must be done regularly, several times a year.
You must use fresh water for cleaning.
Never use abrasive material to clean the stainless steel parts.
Drying the stainless steel parts must be done using a clean dry cloth.
Use specially dedicated stainless steel tools for dismantling the starting blocks.
Applying a hydrophobic silicone type B431 increases the protection of the sensitive areas against
corrosion.
