Safety Labels

NOTE: These drawings indicate the location of safety labels on the machine. If at any time the labels become illegible, promptly replace them.

Electrical:
In the USA, this machine operates on a standard 15 amp 115V, 60 Hz, A.C. power circuit. The amp, hertz, and voltage are listed on the data label found on each machine. Using voltages above or below those indicated on the data label will cause serious damage to the motors.

Extension Cords:
If an extension cord is used, the wire size must be at least one size larger than the power cord on the machine, and must be limited to 50 feet (15.5m) in length.

Grounding Instructions:
This appliance must be grounded. If it should malfunction or break down, grounding provides a path of least
resistance for electric current to reduce the risk of electric shock. This appliance is equipped with a cord having an equipment-grounding conductor and grounding plug. The plug must be inserted into an appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances.

This appliance is for use on a nominal 120-volt circuit, and has a grounded plug that looks like the plug in “Fig. A”. A temporary adaptor that looks like the adaptor in “Fig. C” may be used to connect this plug to a 2-pole receptacle as shown in “Fig. B”, if a properly grounded outlet is not available. The temporary adaptor should be used only until a properly grounded outlet (Fig. A) can be installed by a qualified electrician. The green colored rigid ear, lug, or wire extending from the adaptor must be connected to a permanent ground such as a properly grounded outlet box cover.
Whenever the adaptor is used, it must be held in place by a metal screw.

WARNING : Improper connection of the equipment-grounding conductor can result in a risk of electric shock. Check with a qualified electrician or service person if you are in doubt as to whether the outlet is properly grounded.
Do not modify the plug provided with the appliance – if it will not fit the outlet; have a proper outlet installed by a qualified electrician.

Maintenance

Periodic Maintenance

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. This will prevent build-up of alkaline residue in the system. If spray jets become clogged, remove the spray tips, wash them thoroughly, and blow-dry.

NOTE: Do not use pins, wire, etc. to clean nozzles as this could destroy spray pattern.

Periodically inspect all hoses, electrical cables and connections on your machine. Frayed or cracked hoses should be repaired or replaced to eliminate vacuum or solution pressure loss. If the cable insulation is broken or frayed, repair or replace it immediately. Don’t take chances with electrical fire or shock.

Daily / Regular Maintenance

Before making any adjustments or repairs to the machine, disconnect the power cord from electrical source.

1. Empty unused cleaning solution from the solution tank.

2. Inspect and clean filter screen in solution tank.

3. Flush pumping system with 4 or 7 liters of clean, hot water.

4. 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.

5. Check for and remove any lint or debris around vacuum shoe.

6. Check spray jets for full spray pattern.

7. Remove lint and dirt build-up from brush and housing.
   NOTE: Brush removal.
   a. To remove brush, grab and pull brush out from end opposite drive belt (operator’s right). Remove other end from brush driver.
   b. To install brush, line up slots in brush core with pin in driver on drive belt side (operator’s left) and push brush onto driver. Then snap bearing end (opposite end) of brush into retaining clip.

8. Check cooling air screen (located on frame behind left wheel) for lint or debris.

9. Check float and shut-off screen and clean as necessary.
   NOTE: Always store machine with brush in “Store” position.
