conveyor belt (see Page 55).
2. Clean conveyor rollers.
Emergency

2. Air leaks in system.
3. Brake rotor contaminated with oil.
4. Brake pads worn out.

point.
1. Unless there is clear evidence of an air leak or a per-

take no action.
2. Ensure water filter/trap drain cock is tight.
3. Find source of sound and determine likely cause based
on what you see.
