Important Notice

A. Leakages of air will be sealed automatically but not instantly.

The resin of BEST will continuously coat the wound and any other pores of rubber and will seal them immediately after the product has entered the wound.

This means that some time maybe necessary depending on the damage.

Inject the product, inflate your tyres and let the machine operate. BEST will work better and better as:

  • the tyre spins and there is time for the product to cover the whole internal area
  • the tyre is loaded and flexing of rubber permits resin to enter the pores and wounds
  • the resin gets warm because as a colloidal material the warmer the better glue it becomes.

 

B. BEST will seal damages created by sharp point objects i.e nails and screws, within the limits of sizes covered by Guarantee. Sharp point objects as they are entering the tyre, destroy the rubber mass but do not break the metal belts; therefore the tyre retains its original strength.

BEST is rubber in liquid form; it will cure rubber using rubber; it will never restore the original strength of the tyre if the metal armory is damaged. Rubber cannot cure steel bars.

If a puncture is leaking, although the tyre is protected by BEST, one of the following three reasons may occur:

  1. The wound is too big to be sealed by "BEST". In this case, metal belts are broken and after the wheel is turned so that the wound will come downwards, leakage of air and product simultaneously will be noticed. Repair of such a wound demands replacement of the belts strength that is, an "armed" patch is necessary.
  2. There is not enough quantity of "BEST" in the tyre. This may occur due to installer wrong counting of strokes or malfunction of the pump. In this case, leakage of air only will be noticed, possibly with very small drops of resin. To repair the tyre, turn the wound downwards, install more material in it, up to the listed quantity and inflate the tyre in normal pressure.
  3. There is no air in the tyre. In this case there is no leakage, neither of resin nor of air, but the tyre is flat. The patch will be created immediately after the tyre is inflated and the wound is turned downwards.

As a combination of the above 2 and 3, it is very rare but has been noticed, that some punctures coming from small objects are not sealed. In this case:

  • check the quantity applied in the tyre and add some more product
  • temporarily inflate the tyre 10% more than the normal operating pressure
  • let the machine operate so that the tyre is warm and loaded
  • decrease the tyre pressure to designed level

 

Preparation and Installation

In case the pump has never been used before, please abide by the following steps:

  1. Prolong the sleeve of the pump to its maximum. Put the pump into the pail. The length of the sleeve will be adjusted automatically. This will help to absorb the entire quantity from the pail.
  2. Screw tightly the red cap on the pail. The pump will remain in the pail up to the moment that all the quantity of the liquid is injected into the tyres.
  3. Pump a few strokes so that the liquid will fill the hose and reject one stroke in the waste.
  4. Close the black valve of the nozzle at the end of the hose.
  5. Calculate the volume of “BEST” required per tyre using the tyre volume charts. The volume charts provided by the company are grouped by the rim size. The volumes of product are listed in number of full strokes and in litres. For example to calculate the volumes a small loader with tyres 10.00 – R 16.5 follow the steps below:
    1. find RIM size 16.5 this is in page 6
    2. find the size 10.00 – 16.5
    3. read number of full strokes 25 (piston lifted completely up and pushed completely down)
      invoice your client for 2.5 litres
  6. Wear protective gloves and glasses. Always have in mind the safety measures.
    BEST can be installed in every position of the valve provided it is suitable for the worker.
    12 o’ clock position is more secure for eye protection since valve is turned downwards.
    Now you are ready to start the procedure.

Installation is carried out under the condition that the tyre is on the rim, it already has some air pressure and it is balanced*.
*NOTE: Βalancing of the tyre must be made before the installation of “BEST”

Please abide by the following steps:

  • Unscrew the valve core using a remover. If it is a high-pressure tyre, let some air escape. Please remember that the pump functions in pressure less than 60 psi.
  • Place your finger over the valve to prevent too much air loss. Always wear gloves.
  • With the other hand connect the pump nozzle onto the valve stem and open the nozzle valve.
  • Pump in the calculated strokes. Push the piston slowly. Quick pumping will create under pressure in the drum. As a result when you pull the piston up, the cylinder of the pump will not fill up and you will install less quantity of BEST than the one you think you have installed. Please note: the strokes must be complete. (FULL STROKES) This means that the piston must be lifted completely up and pushed completely down. The number of strokes depends on the size of tyre and you will find this number in the volume charts.
  • In case you feel resistance in pushing down the piston, do not push harder. This is an indication that a big rubber crumb does not permit fluid into the valve. In this case:
    1. close the nozzle valve,
    2. unplug the nozzle chock and let some air to clean the valve,
    3. open the nozzle valve and let depressurization of plastic tube,
    4. close the nozzle valve again,
    5. plug the chock back to the valve and open the valve,
    6. continue the installation up to the calculated quantity.
    If the air pressure in the tyre is not sufficient to wash the rubber crumb from the valve, use a thin and hard piece of wire to clean it. Then inflate the tyre a little bit, so you will have enough air to clean next possible blockage.
  • Close the nozzle valve and remove it. Let some air escape so that the valve tube is free of any rubber crumb and resin that might stick on the core. Place your finger over the valve stem in order to avoid complete deflation of the tyre. Replace the valve core and wash off excess BEST from the rim.
  • Re-inflate the tyre to recommended pressure and replace valve cap.
  • Give the necessary invoice and guarantee to the customer.

 

How to face a Damage

  1. In case the piston goes up and down without injecting liquid into the tyre (So it moves very easily). Please refer to diagram 960,  number 13&14.  Number 14 is a check valve. When you lift the piston up, no. 14 permits the liquid to fill the piston. When you push the piston down no.14 seals the piston and liquid does not return to the pail but it is injected into the tyre. No 13 is a screw nut, which keeps no14 in place. In case the installer push the piston down hardly and for some reason the pump is blocked, then the screw nut no 13 goes down and release the pressure so the piston is not damaged. In this case search in the pail, find the nut and screw it back firmly.
  2. Never pump quickly. As the pressure of the pump is 60 psi, if the piston moves quickly pail starts to shrink. If the pail is shrunk the negative pressure inside the pail does not permit the liquid to enter the piston. So the installer believes that he has injected 100ml but in reality he has injected much less. In case you have a shrunk pail, just unscrew the red cap of the pump and let the air go in. Then start pumping slowly.
  3. To inject 100ml is ABSOLUTELY necessary to lift the piston completely up and push it completely down. To be sure, the installer must hear a noise (tack) going up and then another (tack) going down.
  4. After a long time of use the installer may feel that although he lifts the piston completely up and down, liquid is not injected normally into the tyre. In this case please change the o-ring of the valve. This o-ring is number 12.
  5. In case the pump is blocked because of some thick piece of rubber in combination with fibre, the installer can very easily disassembly every part of the pump and clean it with plain water.
  6. After the installation is completed always plug the chock so that the product in it will not get dry. A simple way is to plug in an old valve with its core in it.

 

The Pump and its Maintenance

The pump is designed and produced according to the specification and technical instructions of the company, so that it will ensure safe installation.
It is hand operated and calibrated to inject approximately100ml of Best, into the tyre. Air operated pump is not recommended for product injection in a tyre due to the possibility of pressure increase in case of blockage of the valve. Blockage of the valve tube may occur since the product contains solid rubber crumbs. In such a case the air pump would stop its operation when the pressure would have reached a dangerous level.

On a regular basis, the pump should be cleaned as follows:

  • Remove the pump out of the pail, unscrewing the red cap.
  • Pump a few strokes with the body of the pump OUT of the pail and the nozzle in the pail, so that all the quantity of BEST will be injected into the pail.
  • Place the pump in a bucket full of clean water and pump through till no sign of material is visible in the plastic tube.
  • Pump a few strokes with the body of the pump outside the bucket so that all water is out of the pump and the hose.
  • Rinse with clean water the body of the pump and the hose.
  • Re-assemble in reverse order.
  • Cover the metal surface of the piston with silicon grease.
  • Screw tightly the pump back to the pail
