○ 

○ 

*

Either of inspection early time is selected. 

 

[Items for visual appearance check] 

1. Loose set screws, abnormal dirt. 
2. Check of flaw and cable joint 

3. Vibration, noise. 

 

[Items for belt check] 

Stop operation immediately and replace the belt when belt appear to be like photos below. 

a . Tooth shape canvas is worn out
