Preventive Maintenance Program
Cleaning and inspection schedule
This is a daily, weekly, and monthly schedule for cleaning and inspections. The PMP has instructions for each task. These
instructions help your personnel understand what to do and what to look for during each task. In general, an operator can
do the daily and weekly tasks, while maintenance personnel usually do the monthly tasks.
A monthly maintenance log is in the back of this manual. You can make photocopies of the maintenance log to record
tasks.
