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 notifi ed immediately.
ELECTRICAL
115V
This machine is designed to operate on a standard 15 amp. 115 volt, 60 hz, AC circuit. Volt-
ages below 105 volts AC or above 125 volts AC could cause serious damage to the motor.
230V
This machine is designed to operate on a standard 8 amp. 230 volt, 50 hz, AC circuit. Voltages
below 210 volts AC or above 250 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 fl ammable 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.
Page 5
Ambassador Jr.
DANGER
Improper connection of the equipment-grounding conductor can result in a risk of electric shock.
Check with a qualifi ed 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 fi t the outlet,
have a proper outlet installed by a qualifi ed electrician.
The 115V version of 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. The 230V version of this applicance is
for use on a nominal 230-volt circuit and has a grounding plug that looks like the plug illustrated
in sketch B.
Make sure that the appliance is connected to an outlet having the same confi guration as the plug.
No adapter should be used with this appliance.
USER MAINTENANCE INSTRUCTIONS
All service and repair should be performed by qualifi ed vacuum service representative or electri-
cian. 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 fi lter and solution inlet strainer daily.
3. Removable recovery tank should be rinsed clean daily.
4. Spray jets should be checked for correct spray pattern and cleaned if plugged. 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.

Ambassador Jr.
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 fl ushed twice, once with the jets installed and once with
jets removed. To fl ush 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. 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 fl ow to the pump and spray jets.
Carpet should be thoroughly vacuumed and obstacles relocated before beginning the cleaning
cycle. Heavy traffi c lane areas should be pre-treated or spotted with Minuteman Pre-Treat order
#902183 for best results.
CLEANING THE AMBASSADOR
1. Always work away from the cord.
2. Machine operates by pulling backwards over carpet.
Page 7
Ambassador Jr.
3. The vacuum lid assembly should be properly seated on the recovery tank for proper vacuum
recovery.
4. See Control Panel section for switch identifi cations:
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 at lower rear panel of machine, until brush pressure gauge reads
in green zone (7).
5. Solution pump should be turned off to the center switch position, (4), approximately 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 fi lter 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 fi tting from clear recovery dome and install auxiliary hose assembly cuff to
grey fi tting 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 .
NOTE: To identify the Water Shutoff Solenoid, see Figures 1 & 2 below.

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 confi ned areas. When
released, switch will return to center off position.
6. Pump auxiliary when using separated fl oor tool or upholstery tool, switch must be switched
to on position. See fi gure 2 for solution hose hook up - aux. out.
7. Brush pressure adjustment gauge.
The brush adjustment knob is located in the lower left back panel. Adjustments made to the brush
pressure are shown on the brush pressure gauge (Item #7). Adjusting the brush past the green
zone on gauge will shorten brush and brush drive motor life.
