PREVENTIVE MAINTENANCE
Various components of the Comet Executive™ Gas require scheduled attention to ensure long life
and trouble-free operation. The Preventive Maintenance (PM) Schedule below and on the next page
outlines all of the PM tasks required at regular intervals. All tasks are the responsibility of maintenance
personnel unless otherwise indicated.
Since operators run the machines, they should be trained on site to visually inspect common areas daily
and notify maintenance personnel when problems are found, such as worn or broken ribbons. All PM
intervals are based on 8-hour/day operation. Increase the PM frequency for two- or three-shift operations.
Preventive maintenance should only be done when the power is turned OFF at the main disconnect
switch. Specic preventive maintenance that requires the unit to be running should be done with extreme
caution and attention to detail.
