Section IV. MAINTENANCE PROCEDURES
a. Introduction. Thorough cleaning is extremely important. A buildup of concrete will cause major problems in
operation such as equipment failures, and the need for frequent maintenance. Also, cleaning becomes harder and harder
if It Is not done well each time
Do not use water to clean the inside of the cement bin. Do not get water on the conveyor belt. Be
sure all access panels are closed before you begin cleanup.
b. Mixing Trough. The mixing trough is difficult to clean because it receives a heavy accumulation of concrete.
However, it Is important to clean it thoroughly.
