The Yamaha α:(alpha)-EX take down bow exhibits the qualities of a toumament bow of the very highest level. It not only in corporates the on-target performance and the unique tackless insertion hub construction, features of the Olympic gold-medal winner - the EX- it also features its own unique double adjusting system, developed through our pursuit of an even easier-to-use bow.

How well the bow continues to give satisfactory performance depends on the way it's used. Please read this manual carefully so you can enjoy high-precision archery performance to the fullest.

HANDLING PRECAUTIONS

1. Be sure to remove the string from the bow when storing it.

2. When storing or carrying the bow, in order not to damage the handle and limbs, wrap them with a cloth and put them in the archery case.

3. Properly place the bow so as not to put improper pressure on it during in use or storage.

4. Do not shoot without an arrow or with the nock disconnected from the bowstring.

5. If the bow gets wet, carefully wipe it off with a dry cloth including the handle/limb joint unit.

6. When storing the bow for a long period of time, lay it horizontally and keep it out of direct sunlight or dampness.

7. If there's any defect in or damage to the handle or limbs, there's a danger of breakage. Be sure to check the bow from time to time for defect or damage. Never modify the handle. Improper modification may cause trouble.

8. The above precautions should be strictly observed. The manufacturer will not bear the responsibility for any problems caused by misuse.

SPECIAL ATTENTION IS CALLED

A magnesium alloy is used in the handle of Yamaha bows. Cracks or breakage to the handle, weakened due to fatigue in the material caused by repeated shooting or corrosion during a long period of use, may occur. If so, immediately discontinue using it and contact the dealer from whom you purchased the bow.

In addition, never modify the handle by shaving it or drilling a hole in it. Any remolding of the handle unit will advance fatigue or corrosion in the metal, reducing its durability.

Yamaha designs and builds its high-quality handles by fully utilizing its long-time expertise and know-how including rational distribution of rigidity, intensive research in handle design and materials and uniformity of casting. To assure the superb quality of the α-EX handle, for instance, Yamaha conducted many stringent tests and trials including durability tests for metal fatigue by sampling every casting lot. In addition, a minimum of 50,000 shots were made in actual shooting with the substantial draw weight of 50 lbs., after which the durability of the handles was checked by X-rays.

Specifications are subject to change without notice.
