1 INTRODUCTION
OSB14 presents a powerful 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.
OSB14 starting blocks are designed with the optimum angles of both the platform and the footrest
for racing starts.
Design research also applied to the top surfaces, very comfortable yet roughs enough to guarantee
the swimmer a feeling of total security.
The length of the platform 74cm adapts 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.
OSB14 allows an easy mounting of OBL1 (Omega Backstroke Ledge) on the platform.

2 INSTALLATION
2.1 Positioning of the OSB14 starting blocks
The OSB14 starting blocks are positioned according to the measures indicated: 238mm from the
swimming pool border (248mm with the OCP5 touchpad) to the front of the base.
The handle of the OSB14 must be aligned with the border of the touchpad (Ex. OCP5).
Are the touchpads missing or is the swimming pool too small with touchpads, align the OSB14
starting block with the border of the swimming pool.
The drilling oblong fixations permits a play of the block; this permits a possible correction of the
alignment.

4.5 Troubleshooting
4.5.1 Detection of a short-circuit
If the buzzer (7) emits a sound while there is no pressure on the platform, proceed as follows:
- Unscrew the 6 A4 conical screws M8 (4) on the platform (2).
- Remove platform (2) and connect the buzzer (7) to the connection cable (6).
- Insert a screwdriver into the 2 holes of the lower frame (3a) and unscrew each of the
adjustment screws (5) until they do not touch the contact head any more (see Detail X).
If the sound continues, verify if the wiring or the frames (fix or mobile) are not in short-circuit
(mechanical or electrical connection).
4.5.2 No contact
If the buzzer (7) does not emit a sound during the sensitivity adjustment, proceed as follows:
- Make sure that the platform (2) and the RBD (3) are correctly assembled; there must be a
visible movement (Paragraph 4.6).
- Make sure that the 2 adjustment screws (5) are not too far apart.
4.5.3 Sensitivity adjustment
If the sensitivity is out of the range between 13kg and 18kg (as indicated in paragraph 4.2), make
an adjustment by proceeding as follows:
- Connect the buzzer (7).
- Insert a screwdriver in one of the holes of the lower frame (3a) then screw the adjustment
screw (5), facet after facet of the hexagonal head until the buzzer emits a sound.
- Unscrew the adjustment screw (5) by turning it 4 facets backwards (0,16mm/facet).
- Adjust the second screw (5) in the same way.
- Make a test with the dynamometer (8) by pushing or pulling the upper frame (3b).
- 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 (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.
