PREVENTIVE MAINTENANCE

Preventive maintenance consists of inspection, cleaning, and lubrication. These routine

procedures will ensure maximum life and trouble-free operation. While the maintenance schedule

presented in this section should remain flexible, modifications should be based on experience

with operating the equipment at your facilities. A maintenance log should be kept to help establish

a preventive maintenance schedule, as well as to monitor and adjust the schedule as necessary

throughout the equipment’s life. When establishing a preventive maintenance schedule, consider

duty cycle, ambient temperature, and operating environment. The recommended preventive

maintenance schedule is presented in the table below.
