Disconnect power to machine before performing monthly maintenance procedures.

 

 

 

 

 

 

1.

Each month OR every 200 hours of operation, lubricate bearings.

 

 

 

 

 

 

 

 

 

 

2.

Clean AC drive fins.

 

 

 

 

 

 

 

 

 

 

3.

Determine if V-belts require replacement or adjustment:

 

 

 

 

 

 

 

 

 

 

 

a. Check V-belts for uneven wear and frayed edges.

 

 

 

 

 

 

 

 

 

 

 

b. Verify that V-belts are properly tensioned.

 

 

 

 

 

 

 

 

 

 

 

c. Verify that V-belts are properly aligned.

 

 

 

 

 

 

 

 

 

 

4.

Remove back panel and check hoses for leaks.

 

 

 

 

 

 

 

 

 

 

5.

Unlock hinged lid and check supply dispenser hoses and connections.

 

 

 

 

 

 

 

 

 

 

6.

Clean inlet hose filter screens. Replace if worn or damaged.

 

 

 

 

 

 

 

 

 

 

7.

Tighten motor mounting bolt locknuts and bearing bolt locknuts, if necessary.

Remove lower rear panel and inspect drive belts for uneven wear, frayed edges or

Remove lower front panel. Check all hoses and temperature probe for leaks,

 

 

 

 

 

cracking and deterioration.
