OVERALL MACHINE MAINTENANCE
Maintaining the original appearance of your unit is important for two reasons:
1. It represents a big dollar investment for your cleaning business and its
appearance should reflect that fact. A dirty machine is not professional.
2. Maintenance, troubleshooting, and repair is much easier to accomplish
on a clean, well maintained unit. Regular cleaning of the machine offers you
an opportunity to visually inspect all facets of the machine and spot potential
problems before they occur.
The following maintenance is recommended by the manufacturer at the frequency
indicated.
AFTER EACH JOB
1. Check recovery tank, stainless steel filter and filter bag as required.
DAILY
1. Wipe machine down thoroughly with a damp cloth.
2. Flush recovery tank out thoroughly.
3. Empty filter bag and inspect for rips, tears, etc. Replace as needed.
4. Remove, thoroughly clean and reinstall stainless steel filter screen in
recovery tank.
5. Inspect and clean vacuum slot on cleaning wand.
