Windsor 621-222MO manual Maintenance, Unplug power cords before servicing or making any repairs

DAILY MAINTENANCE

Unplug power cord(s) before servicing or making any repairs.

1.Flush the entire system, including floor tool, hand tool, etc., with 1 to 3 gallons of clean, hot water.

2.Vacuum out the solution tank.

3.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. Wastewater should be disposed of properly.

4.Occasionally check filter screen at the bottom of the solution tank and rinse clean with hot water if necessary.

5.Inspect hoses for wear. Frayed or cracked hoses should be replaced to avoid vacuum or solution pressure loss.

6.Inspect power cord for wear or damage. This cable will lie on wet carpet. To prevent electrical shock replace cords that are frayed or have cracked insulation immediately.

7.Clean all dirt and obstructions from drain valve and gaskets to prevent possible leakage and premature wear.

8.Run clean water through solution pump when work is complete.

9.Empty both tanks and rinse, run vacuum (s) for at least one minute to dry motor(s).

10.Store with access covers removed to allow tanks to dry.

DO NOT attempt to repair hose! Repairing high-

pressure hoses may result in severe burns and serious injury.

PERIODIC MAINTENANCE

1.Twice a month, flush a white vinegar solution (One quart vinegar to two gallons of water) or anti-browning solution (mixed as directed) through the extractor, turning pump switch on/off several times, flush with clean water. This will prevent build-up of alkaline residue in the system.

MAINTENANCE

2.Check hoses for wear, blockages, or damage. Frayed or cracked hoses should be repaired or replaced to eliminate vacuum or solution pressure.

3.Check all handles, switches, knobs, electrical cables and connections on your machine for damage. If the cable insulation is broken or frayed, repair or replace it immediately. Don’t take chances with electrical fire or shock.

4.Clean out solution tank. Remove and clean solution screen.

5.Clean outside of all tanks and check for damage.

MONTHLY MAINTENANCE

1.Check all bearings for noise and wear.

2.Check all gaskets for wear and leakage.

3.Check pump pressure; observe spray pattern and check gauge if necessary.

4.Check overall performance of machine.

SEMI-ANNUALLY

1. Check vacuum motor brushes.

LUBRICATION

For pressure regulator and pump cam lubrication, use a light silicone lubricant which will not damage o-rings. A small tube (86246790 – PRV NO.

51391) is supplied with your machine.

STORAGE

Thoroughly clean machine if it is to be stored. You must protect this machine from freezing while in storage.

By using the Self Priming Lever you may help clear out all water lines.

Make sure both recovery and solution tanks are empty. Turn on both vacuum switches and press lever. All water should be removed and sprayed into the recovery tank.

Empty the remaining water and wipe dry.

HEAT MODELS ONLY: Be sure to thoroughly drain water out of heater lines prior to storage in colder climates. This heater will freeze and possibly crack voiding your warranty.
