When using an electrical appliance, basic precautions should always be followed, including the
following:
READ ALL INSTRUCTIONS BEFORE USING
WARNING - To reduce the risk of fire, electric shock, or injury:
• Do not leave appliance when plugged in. Unplug from outlet when not in use and before servicing.
WARNING
To reduce the risk of electrical shock, do not expose to rain. Store indoors.
• 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 manufacturer’s recommended attachments.
• Do not use with damaged cord or plug. If appliance is not working as it should, has been dropped,
damaged, left outdoors, or dropped into water, return it to a service center.
• Do not pull or carry by cord, use cord as a handle, close a door on cord, or pull cord around sharp
edges or corners. Do not run appliance over cord. Keep cord away from heated surfaces.
• Do not unplug by pulling on cord. To unplug, grasp the plug, not the cord.
• Do not handle plug or appliance with wet hands.
• Do not put any object into openings. Do not use with any opening blocked; keep free of dust, lint,
hair, and anything that may reduce air flow.
• Keep hair, loose clothing, fingers, and all parts of body away from openings and moving parts.
• Do not pick up anything that is burning or smoking, such as cigarettes, matches, or hot ashes.
• Do not use without dust-bag and/or filters in place.
• Turn off all controls before unplugging.
• Use extra care when cleaning on stairs.
• Do not use to pick up flammable or combustible liquids such as gasoline or use in areas where
they may be present.
• Connect to a properly grounded outlet only. See grounding instructions.
SAVE THESE INSTRUCTIONS
1
INSPECTION
Carefully unpack and inspect your machine for shipping damage. Each unit is tested and thoroughly
inspected before shipment, and any damage is the responsibility of the delivery
carrier who should be notified immediately.
ELECTRICAL
This machine is designed to operate on a standard 15 amp. 115 volt, 60 hz, AC circuit. Voltages
below 105 volts AC or above 125 volts AC could cause serious damage to the motor.
WARNING
Electric motors can cause explosions when operated near explosive materials or vapors.
Do not operate this machine near flammable materials such as solvents, thinners, fuels,
grain dust, etc.
GROUNDING INSTRUCTIONS
This appliance must be grounded. If it should malfunction or breakdown, 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 sketch A below. Make sure that the appliance is connected to an outlet having the
same configuration as the plug. No adapter should be used with this appliance.
2
USER MAINTENANCE INSTRUCTIONS
All service and repair should be performed by qualified vacuum service representative or electrician.
No user serviceable components are employed in the electrical vacuum lid head assembly. No
lubrication of the motor is required.
DAILY MAINTENANCE
1. Solution tank should be emptied after each use. Flush pumping system with 2 or 3 gallons of
clean hot water.
2. Check and clean vacuum inlet filter (page 7, item 118) and solution inlet strainer (page 7, item 1)
daily.
3. Removable recovery tank, page 7, item 40, should be rinsed clean daily.
4. Spray jets should be checked for correct spray pattern and cleaned if plugged (page 7, item 55).
Spray jets are quick release 1/4 turn type. By twisting item 121 1/4 turn counter clockwise, jets
can be removed for cleaning. Do not clean out spray tips with pins or wire, this may cause damage
to the jet spray pattern and cause streaking.
5. Protect equipment from freezing. Severe pumping system damage can occur if allowed to freeze.
6. Inspect vacuum hoses for tight connections. Check electrical cable for abrasion or cuts in jacket.
Cord should be replaced if worn or damaged.
MONTHLY/BI-MONTHLY MAINTENANCE
The Ambassador Solution Pump System should be purged twice monthly to remove alkaline residue
build-up. The system should be flushed twice, once with the jets installed and once with jets removed.
To flush system out, use 1 quart of white vinegar to two gallons of clean hot water, followed by a clear
2 gallon rinse. Clean spray jets if required.
CORD STORAGE
While not in use storage can be accomplished by winding cord around rear of machine. Cord hooks
are provided.
• Do not use with damaged cord or plug. If appliance is not working as it should, has been dropped,
damaged, left outdoors, or dropped into water, return to service center.
• Do not pull or carry by cord, use cord as handle, close a door on cord, or pull cord around sharp
edges or corners. Do not run appliance over cord. Keep cord away from heated surfaces.
• Do not unplug by pulling cord. To unplug, grasp the plug, not the cord.
• Do not handle plug or appliance with wet hands.
This equipment should be stored indoors and not exposed to rain.

OPERATING INSTRUCTIONS
FILLING THE AMBASSADOR
Remove clear solution cover lid from front of machine, page 7, item 32. Fill solution tank with desired
amount of warm water and add liquid cleaning chemical, Minuteman Extraction Shampoo order
#902163. (See instructions on container for proper dilutions.) DO NOT USE powdered cleaning
chemicals. Powders are unlikely to dissolve thoroughly, resulting in clogging the inline solution strainer.
This can reduce or stop solution flow to the pump and spray jets.
Carpet should be thoroughly vacuumed and obstacles relocated before beginning the cleaning cycle.
Heavy traffic lane areas should be pre-treated or spotted with Minuteman Pre-Treat order #902183
for best results.
TO BEGIN CLEANING:
1. Always work away from the cord.
2. Machine operates by pulling backwards over carpet.
3. Vacuum Lid Assembly (page 7) should be properly seated on Recovery Tank (item 40) for proper
vacuum recover. See figure 3 for hose hookup.
4. See page 5, Control Panel Switch Identifications: Normal Cleaning Mode
1. Turn on vacuum switch (1).
2. Turn on brush switch (2).
3. Turn on pump switch to continuous (3).
4. Adjust brush pressure (figure 2) at rear of machine, until brush pressure gauge reads in green
zone.
5. Solution pump should be turned off to the center switch position, page 5 (4), 6" before the end
of each cleaning pass.
During the cleaning cycle, care should be taken not to allow foam to build up in the recovery tank. If
this should happen, the machine should be turned off. Defoamer order #910543 should be added to
the recovery tank only, never into the solution tank. Foam should not be allowed to enter vacuum filter
screen.
The recovery waste water level can be viewed from the operator’s position of the machine through
the visible recovery dome. When waste water is within 2" of the top of the recovery tank, the tank
should be emptied. (NOTE : Never tilt machine completely back with recovery tank in place. Always
remove tank and set to the side before tilting complete machine.) Recovery tank can be emptied by
lifting visible recovery dome and lifting out tank by front handle. A handle gripping area is provided in
the front bottom of the recovery tank to tilt and pour the waste water out.
AUXILIARY TOOL HOOK UP
1. Remove grey hose fitting from clear recovery dome and install auxiliary hose assembly cuff to
grey fitting by passing through rear of machine. Hook up solution hose to auxiliary out coupler at
rear of machine.
2. Turn vacuum switch to on.
3. Turn pump auxiliary switch to on (page 5, item 6). All other switches should be off.
4
OPERATOR VIEW OF CONTROL PANELS
1. Vacuum switch
2. Brush switch
3. Pump spray switch, continuous operation position. Pump supplies solution to spray bar for cleaning
in large open areas.
4. Center position is “off”.
5. Momentary position is for intermittent spray for cleaning in smaller more confined areas. When
released, switch will return to center off position.
6. Pump auxiliary when using separated floor tool or upholstery tool, switch must be switched to on
position. See figure 2 for solution hose hook up - aux. out.
7. Brush pressure adjustment gauge.
See figure 2 for brush adjustment knob location. Adjustments past the green zone on gauge will
shorten brush and brush drive motor life.
