3.1 - Opening the Unit for Maintenance
To open your Grand Prix™ for maintenance, use a drill with a
3/8" bit to remove the bolts holding the Grand Prix's™ body
together. Lift up on the push handle to open the machine like a
♦
clam shell.
3.2 - Filter Maintenance
The Grand Prix™ has a small filter at the top of the vacuum
stack in the recovery tank. This filter should be checked after
♦
each use.
3.3 - System Maintainer
Regular flushing of the solution system with Mytee System
Maintainer keeps your extractor running efficiently by removing
hard water scaling that builds up in the system.
How to use System Maintainer:
