5. Is there any abnormal noise or unusual vibration during operation, and the lubricating condition of transmission chain is good?
Testing method
Chain length accuracy should be measured according to the following requirements
A. Before the measurement, the transmission chain is cleaned
B. The drive chain will be measured around the two sprockets, the upper and lower sides of the measured drive chain should be supported
C. Before measuring the drive chain should be applied in the third ㄧ minimum ultimate tensile load to stay 1min
D. Measurement, the transmission chain imposed on the provisions of the measurement load, so that the upper and lower transmission chain tension on both sides of the chain should ensure that the normal gear
E. Measure the distance between two sprockets
