Unplug machine from electrical outlet before doing any maintenance.
Débranchez la machine de la prise électrique avant de procéder à la
maintenance.
Daily Maintenance
Strippers and some detergents produce foam which will damage the vacuum motors. The vacuum shut-off may not
be sensitive to all foams. Be sure to check that the tank is not fi lling with foam. Use a defoaming agent to avoid pull-
ing foam through vacuum motor. Should vacuum motor become wet, remove source of overfl ow and immediately
run vacuum motor open to dry.
At the end of each working day:
1. After each use, rinse tank with fresh water. Periodically inspect the recovery tank and decontaminate,
using a Hospital Grade Virucide or a 1:10 bleach to water solution. Wastewater should be disposed of
properly.
2. Remove head assembly and allow tank to dry.
3. Remove fi lter for cleaning or to allow to dry.
4. Inspect hoses for wear. Frayed or cracked hoses should be replaced to avoid vacuum loss.
5. Inspect power cord for wear. This cable will lay on wet surfaces. To prevent electrical shock replace cords
with frayed or cracked insulation immediately.
Periodic Maintenance
1. Check fi lter for wear. Replace dirt saturated fi lters that do not respond to normal cleaning.
2. Inspect gasket seals and replace those which have begun to leak.
3. Examine carbon motor brushes and commutator.
