Edge MAXX Preventive Maintenance

PREVENTIVE MAINTENANCE
Various components and parts of the Edge Maxx
®
spreader/feeder require scheduled attention to
assure long life and trouble-free operation. The Preventive Maintenance (PM) Schedule below 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. Specific preventive maintenance that requires the unit to be running should be done with extreme
caution and attention to detail.
