A Few Words of Advice on Using XADO

1. The principles for applying XADO successfully

1.1 Apply the technology within the right scope:

• The friction pair must be metal-on-metal, with at least one side being a ferrous metal.
• Wear must be below 100%.
• There must be no mechanically damaged parts (seizure, breakage, cracks, chips, nicks, pitting or deep scoring).
• The friction system must be strong enough.
• The correct, sufficient amount of XADO compound must be present in the friction contact zone between the two metal surfaces.
• The equipment must run for the required length of time.

1.2 Follow the usage procedure for each XADO compound exactly as given in the Products section.

Please follow these principles whenever you use an XADO product, so that you succeed and don’t waste money. The notes below expand on a few of these points and add some practical experience for your reference.

2. Assessing the wear level correctly comes first

• When evaluating wear, combine the input from XADO, a specialist in the type of machine being treated, and the technician responsible for operating it. The aim is to make sure no part, assembly or whole machine has already reached or passed 100% wear.
• Check the machine’s records for the rated specifications, hours in service, whether past repairs and the parts used met requirements, and the scope and date of the most recent repair.
• Measure the technical parameters using the machine’s own gauges or external instruments.
• Discuss and analyze the machine’s current condition carefully on the basis of the measured figures, then agree on a conclusion about the wear level. Wear below 100% can be treated with XADO. If any assembly or part has reached or exceeded 100% wear or has mechanical damage, repair it first, and only then use XADO.

3. A machine is a set of closely linked assemblies and parts that together determine how well the whole machine runs

XADO does not restore every part, so treatment cannot be viewed as a substitute for other measures. On a motorcycle, for example, XADO will not restore the rubber components (a non-metallic material), the carburetor, the ignition system or the clutch. XADO may raise compression, but if the spark is weak, the air-fuel mixture is set wrong, or the clutch plates are glazed and worn, the bike will still run rough. So you need to carry out a service or repair at the same time as the XADO treatment. Once restoration is finished, retune and readjust the whole machine to suit its new condition.

4. Use the full dose and keep to the correct timing

The doses are spelled out clearly in the Products section. Some customers want strong results but use less XADO than specified. An insufficient amount cannot deliver high quality. For older machines, the instructions call for an increased dose on the second and third applications, but not on the first; be careful to follow this. The intervals between applications given in the instructions must be respected so that the concentration of XADO in the oil stays stable throughout the restoration period. Do not assume that using more XADO than specified in a single application is better.

5. Even with the full dose and enough running time, results will fall short if the XADO does not reach the friction surfaces, or does not reach enough of them

The main causes are:

• Most oil lubrication systems have filters. A coarse filter only needs a thorough clean. The fine filter needs special attention. Many have very high filtration ratings of around 10 microns, with elements made of cotton fiber, paper or porous chemical media. XADO particles are about 5 microns, so in principle they pass through. But used oil carries a lot of contaminants, some of which harden into deposits, and the older the machine and the poorer its past maintenance, the more of these there are. When you change to fresh oil without following the procedure properly, you may find that even just a few hours after the change, the oil has already turned dark. This is easy to see on old, high-output and very-high-output diesel engines. These deposits get caught by the fine filter element, the filter pores shrink, and quite a few XADO particles are held back along with them. Because of this, we always alert customers to the fine-filter issue. The handling is described in detail in the instructions, so please pay attention to it.
• If the machine is fairly new, has been well maintained, and carries few deposits, you can do the following when using XADO: change to fresh oil by the proper procedure, clean the coarse filter thoroughly, fit a new fine filter, and use the hydraulic XADO compound at the dose for the dedicated compound, or 1.2 to 1.5 times that if possible. For example, say you have a late-model Toyota with a few tens of thousands of kilometers on it, running well, and you want XADO to keep it in good shape for longer. Do the steps above, and use the hydraulic XADO compound in place of the gasoline-engine compound at 0.9 ml per liter of oil (or higher, 1.08 to 1.35 ml per liter), keeping the usual three applications. The XADO particles in the hydraulic compound are finer than those in the engine compound, so they pass through the filter more easily.
• Active lubrication systems have an oil pump, usually a gear or rotor type. On very old machines, these pumps are often badly worn but rarely given attention. A weak pump means low oil pressure and poor oil circulation, especially in tight contact gaps, which also limits what XADO can do. If the pump is too worn, repair it before using XADO.
• When changing to fresh oil to prepare for the XADO treatment, follow the technical requirements exactly: run the engine up to operating temperature, stop it, drain all the oil, flush the block thoroughly with Donax F30 or a similar flushing oil, blow out all the flushing oil, and fill with fresh oil. Any oil can be used. However, we recommend a regular oil during the restoration period, because very expensive oils with premium friction-reducing additives slow down the action of XADO. Once the XADO treatment is complete, any oil is fine.

6. The ceramic-metal protective layer builds up on the metal surface gradually and slowly

The treatment requires enough running time. Without running, XADO does nothing. After each application, run the machine straight away. Running it continuously for several hours is excellent. Only after running it for the specified time and readjusting the whole machine can you judge how much XADO has achieved.

7. How to assess wear on a motorcycle

For a professional technician, this is not difficult. Here we point out a few easy-to-spot signs so that most owners can assess their own bike.

• Go by the kilometers covered. New bikes from reputable makers such as Honda, Yamaha and Suzuki can often run 50,000 to 100,000 km before the cylinder-piston assembly needs a major repair. Lower-quality bikes may need top-end work after only 20,000 to 40,000 km, sometimes less, after which the interval between top-end repairs tends to be 20,000 to 35,000 km or shorter.
• Go by how the bike behaves: poor pulling power, hard starting, an unstable idle, higher fuel and oil consumption, the start of blue or bluish-white smoke, and a wet black sooty deposit on the spark plug even after the carburetor and ignition have been carefully adjusted. These points indicate wear reaching 100%, calling for a major repair of the top end and cylinder head. If there is abnormal knocking in the crankcase, open up the engine and inspect and repair the bottom end as well.

8. When to use XADO on a motorcycle

• You can use it when the bike is still new, or, ideally, while it is still running normally with low wear below 50%. These cases are the easiest to bring back to as-new condition. Genuine bikes from reputable makers built in their home country do not necessarily need early treatment; you can run them through about 70% of their first service life before using XADO. The reason is that these bikes are made with good technology, materials and surface strengthening, so they last a long time.
• Using it early, before heavy wear sets in, pays off, because you can easily get the bike back to perfect as-new condition. After that, you can run it with confidence, lasting 2 to 3 times longer than without XADO. For the small cost of using XADO, you save many times that over the life of the bike, because a teardown and repair stays a long way off and fuel use is lower.
• If you leave it too late, when wear is already high, some parts will have worn badly in spots even if the engine as a whole does not yet seem far gone. Examples include a few deep scratches on the cylinder or piston, piston rings worn close to their limit, a collapsed main bearing, or a heavily worn piston pin. Some of these parts, especially the poorly lubricated ones, cannot be brought back to the perfect condition you want.

9. Keeping a motorcycle in good shape for the long run

• For a bike you can trust every time you get on it, look after it well. The engine is the bike’s main assembly and usually the source of the most trouble. Keep teardowns to a minimum. Often, a bike runs worse after being taken apart and put back together, and ends up leaking oil constantly.
• Use XADO so the engine reaches good condition and stays firmly protected. After restoration, carefully tune the ignition, carburetor, valves, clutch, and sprocket and chain so the bike runs perfectly, saves fuel, and goes a very long time before needing repair.
• Once you have used XADO to get the bike in good shape, after a year of riding, use 1 to 2 tubes of XADO again as preventive maintenance. Anything slightly worn gets topped up and restored, and the bike holds its strength for the long run.
• You can use XADO for preventive maintenance once a year, with much the same result. (Note: this point is cut off in the original.)

This is how to care for a bike with XADO: low cost, very few repairs, and long life. The fuel and oil savings alone are enough to cover what you spend.

10. A note on smoke after restoring an old bike

Sometimes an old bike, after being restored and run for a while, shows some smoke and a slightly wet spark plug even though it is still very strong. The usual causes are worn piston rings, an oil seal, or a valve stem guide. These parts were already badly worn before XADO was used, and if they went unnoticed during treatment, you simply replace them and lap the valves, with no need to rebore the cylinder. Once that is done, when you have the chance, put one tube of XADO into the crankcase.
