OPERATION

This machine is a commercial vacuum designed for wet and dry pick-up.

Dry soil can be vacuumed directly into the tank. To empty the tank of dry soil, remove the top and dump into trash receptacle.

For wet pick-up, remove polyester filter. The machine is equipped with a float shut-off. As the tank is filled to capacity, a float rises and seals the vac intake, causing loss of vacuum. Switch off the vacuum when this happens and bring the machine to a floor drain.

Use the convenient drain hose at the back of the vacuum to empty the tank.

With both wet and dry applications be sure to frequently clean the filter. This is especially true when the vacuum is being used with strippers and wax.

DAILY MAINTENANCE

Caution: Strippers and some detergents produce foam which will damage the vac motors. The vac shut-off may not be sensitive to all foams. Be sure to check that the tank is not filling with foam. Use a defoaming agent to avoid pulling foam through vac motor. Should vac motor become wet, remove source of overflow and immediately run vac 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 if necessary, using a Hospital Grade Virucide or a 1:10 bleach to water solution. Waste water should be disposed of properly.

2.Remove head assembly and allow tank to dry.

3.Remove filters 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.
