6.3 Precaution on maintenance 

 

Caution 

1.  Cut the power supply during maintenance and replacement of the product.   

2.  Put on protective goggles when applying grease.   

[Maintenance frequency] 

Perform maintenance according to the table below.   

 

Appearance check 

Check belt 

Inspection before daily operation 

○

 - 

Inspection every six months      * 

- 

○

 

Inspection every 250km    *

 

- 

○

 

Inspection are every five million times * 

- 

○

 

  *

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] ( 

LESH*R / LESH*L )

 

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

a. Tooth shape canvas is worn out 

Canvas fiber becomes fuzzy. Rubber is removed and the fiber becomes whitish. Lines of fibers 
become unclear.   

 
 
 
 

 

 

b. Peeling off or wearing of the side of the belt 

Belt corner becomes round and frayed thread sticks out.   
 

     

c. Belt partially cut

 

 

Belt is partially cut. Foreign matter caught in teeth other than cut part causes flaw.   

 

 
 
 

 

d. Vertical line of belt teeth   

Flaw which is made when the belt runs on the flange. 
 

e. Rubber back of the belt is softened and sticky. 

 

f. Crack on the back of the belt
