Some fittings may deteriorate over extended periods of time due to wear and or corrosion. For optimum safety, the installation should be checked thoroughly at regular intervals. English Yamaha cannot be held responsible for damage or injury caused by insufficient strength of the support structure or improper installation. ¦ Using eye bolts for suspension For optimum safety, make sure to carefully follow the precautions below.

Make sure that the load for each eye bolt is less than 740 kg when suspending at an angle of 0 degrees, and less than 185 kg at an angle of 45 degrees. CAUTION When using the eye bolts, make sure that the suspension angle is within the range of 0 to 45 degrees, as shown below. 0. (740kg) 45. (185kg) 90.
