Maintenance Overview
•
VST recommends conducting Maintenance on the GREEN MACHINE annually to make sure all
the components are in good working order. If the annual maintenance is not conducted, there
is a possibility the GREEN MACHINE may not be operating properly.
•
The Vacuum Pump and Control Valves are the only components with moving parts in the GREEN
MACHINE; therefore, it requires very little maintenance.
•
All replacement parts must be from VST’s recommended replacement parts list located in
Chapter 9: Replacement Procedures Section.
•
If the GREEN MACHINE is not functioning properly consult Chapter 8: Troubleshooting Section to
determine which component may need to be repaired or replaced.
