• Do not allow to be used as a toy. Close attention is necessary when used by or near children.
• Use only as described in this manual. Use only the manufacturer’s recommended attachments.
• Do not use with a damaged cord or plug. If the appliance is not working as it should, has been dropped,

GROUNDING INSTRUCTIONS
This appliance must be grounded. If it should electically malfunction, 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 plugged into an appropriate outlet that is properly installed and grounded in
accordance with all local codes and ordinances.
DANGER!
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.
This appliance is for use on a nominal 120-volt circuit, and has a grounding plug that looks
like the plug illustrated in Figure 1 below. A temporary adapter illustrated in Figures 2 and
3 may be used to connect this plug to a 2-pole receptacle as shown in Figure 2 if a properly
grounded outlet is not available. The temporary adapter should be used only until a properly
groundedoutlet (Figure1) canbe installedby aqualified electrician.The green-colored rigid
ear, tab, or the like extending from the adapter must be connected to a permanent ground
such as a properly grounded outlet box cover. Whenever the adapter is used, it must be held
in place by a metal screw.

PREPARING THE MACHINE FOR USE
FILL THE SOLUTION TANK
1. Lift the front Solution Fill Cover off the machine.
2. Read the dilution instructions on the chemical container. Then figure the proper amount
of chemical to mix with 25 gallons (94.5 liters) of water. For best results, use the
Advance CarpeTeam™ Extraction Cleaner chemical specially formulated for use with
Advance carpet extractors.
3. Pour the chemical in the solution tank and fill the tank with warm water to 1-3/4 inches
below the inside edge of the opening.
4. Put the Solution Fill Cover back on the machine.
CAUTION!
Use only low-sudsing, liquid detergents designed for carpet extraction.
PRE-SPRAY THE CARPET
Pre-spray spots and heavy traffic areas before extracting. Use a hand-held bottle sprayer
or a pressurized “Hudson” type sprayer. Mix the pre-spray according to the chemical
manufacturer’s directions. For best results, use the Advance CarpeTeam™ Pre-Spray
chemical specially formulated for use with Advance carpet extractors.
PLAN FOR CLEANING
Before you begin extracting, look at the area to be cleaned and plan your work. Divide the
space into sections. Overlap each pass 2 inches (5 cm).
