•The Model BEXT®-100, 100H, 150H or 300HV is an extractor for cleaning carpet. When used with a floor tool, the
machine applies cleaning solution to the carpet and removes the dirty solution and soil from the carpet.
•Theextractorhascontrolstostartthepumpforthesolutionandthemotorforthevacuum. Thefloortoolshavecontrols
to release the solution.
•The extractor has a bypass pump. The pump runs when switched on, bypassing solution internally to keep pressure
even.The extractor starts when the solution lever on the floor tool is activated.
NOTE: Whenusingthe extractor tocleancarpets,followthis procedure:
1. Do not walk on freshly cleaned carpets for at least four hours or until the carpet is dry to touch.
2. Donot removealuminumorplastic piecesthathavebeen placed underthelegs of furnitureuntil
the carpet is dry.
3. Do not allow children or pets to crawl or walk around on the damp carpet.
4. Vacuum right after the carpet is dry and then vacuum the carpet once a week as needed.

INSPECTION:CarfefullyunpackandinspectyournewExtractorforshippingdamage. Eachunitistestedandinspected
before shipment. Any damage incurred is the responsibility of the carrier, who should be notified immediately.
CLEANING SOLUTIONS: We recommend liquid cleaning chemicals. A pH of 7-9 is strongly recommended to avoid
premature pump wear, which would voide the warranty.

Topreparethe machineforoperation,followthisproce-
dure:1. Connect the vacuum hose to the hose connector
on the extractor and to the end of the vacuum tube
on the floor tool. See Figure 1 D, E
2. Connect the solution hose to the extractor and the
floor tool. To fasten the quick disconnect fitting,
slide the knurled collar on the female coupling
away from the opening. Push the male coupling
into the female coupling. See figure 3 A & B
WARNING: Do not use water that is hotter than
120°F (48°C).
3. Before moving the extractor onto the carpet, put
clean hot water into the solution tank.
4. Add a cleaning chemical, such as Clarkare®Ex-
tractor Concentrate, to the hot water. For the
correctamount, followthe directionsshown onthe
container.
Set-Up
WARNING: We recommend that you use liquid
cleaningchemicals. Powdercandam-
age machine. Powders can cause
build-up in the lines, heater, pump,
quick disconnects, etc., all of which
would void the warranty on those
items. A pH of 7-9 is strongly recom-
mendedtoavoiddamageandprema-
ture wear to the pump, which would
void the warranty.
Fill the holding tank with clear water and the detergent of
your choice. Mix well. Although this machine is designed
tosupplyinstant hotwater,theadditionofwarmorhotwater
to the holding tank is beneficial and will reduce pre-heat
times.
A. Plug in cord #1 (vac and pump), identified by the red "H"
on the end of the cord. Attach the priming hose to the
machine(on300HVonly). Turnthepumponandsetthe
switch to the upholstery setting. Run until the pump is
fullyprimed,thenturnoffthepump. Removethepriming
hose and attach the cleaning hoses and tool.
B. Turn on the pump and spray through the cleaning tool
for a few seconds to fill the lines with solution.
BEXT®100H, 150H & 300HV
C. Plug in cord #2. The "Locator" light will illuminate when
the cords are plugged into separate circuits. Turn the
"Heat" switch on; wait two minutes for the heat ex-
changer to reach operating temperature. You may now
begin cleaning. It will take about 10 seconds for the
initial heat to reach the wand. The "Mode" light will turn
on when the heat exchanger is actively heating. (See
Figures 5, 6 and 7)
NOTE:Ifthe"Locator"indicatorlightdoesnotilluminate
when cord #2 is plugged in, then both cords are on the
same line. Try other outlets until the light comes on.
CAUTION: If both cords are plugged into the
samecircuitbreaker,thebreakermay
blow when operating with the heater
on.

5. If the extractor removes an excess amount of foam
from the carpet, add a de-foamer such as Clarkare®
De-foamer Concentrate to the recovery tank. The
amount needed will vary according to the amount of
detergent already in the carpet.
CAUTION: Topreventdamage,useawater-basedde-
foamer ratherthananoil-basedde-foamer.
CAUTION: Donot leavetheextractororothercleaning
machines or tools on the carpet when not
inuse. Cleaning solution in the machines
and tools can leak onto the carpet and
cause light spots or stains.
NOTE: To order Clarkare®Extractor Concentrate, order
part no. 398421. To order Clarkare®Defoamer,
order part no. 398420.

INSTRUCTIONSFORCONNECTIONTOTHE
POWERSUPPLYANDELECTRICALGROUND- 120V
CAUTION: This machine will operate only on an
AC frequency and on the specified
electrical voltage shown on the name-
plate. Make sure you have the cor-
rect frequency and voltage before
connecting the power cord to an out-
let.
Thismachine mustbe connectedtoan electricallygrounded
circuit in order to protect the operator from electric shock.
This machine has an approved power cord with three
conductors as well as a plug with three terminals. Connect
the plug to a three holed receptacle. For maximum
protection against electric shock, use a circuit that is
protected by a ground fault circuit interrupter.
This machine uses a 120 volt AC 50/60 cycle electrical
circuit. Make sure you have the correct frequency and
voltage before connecting the power cord to an outlet. The
machine has a plug as shown in Figure 7. If a receptacle
connected to the electrical ground as shown in Figure 7 is
not available, contact an electrical contractor. Do not use
an adapter.
WARNING: To prevent possible electric shock,
protect the machine from rain. Keep
the machine in a dry building.
WARNING: To prevent possible electric shock,
always use a 3-wire electrical system
connected to the electrical ground.
For maximum protection against elec-
trical shock, use a circuit that is pro-
tected by a ground fault circuit inter-
rupter. Consult your electrical con-
tractor.
WARNING: Do not cut, remove, or break the
ground pin. If the outlet does not fit
the plug, consult your electrical con-
tractor.
WARNING: If the cords or plugs are worn or
damaged in any way, have them
replaced by an authorized service
person.
Extension Cords
Useonlyan approved extensioncordwith three conductors,
a plug with three terminals and a three-holed connector
body. This machine has a power cord with a wire size of 12
AWG. (AWG stands for American Wire Gauge).
CAUTION: If you use an extension cord, use one
that has a minimum wire size of 12
AWG. Be sure your extension cord is
no longer than 50 ft. Do not join two
extension cords.

How To Get Access To The Pump and Vacuum
Motor
To get access to the pump and the vacuum motor,
followthis procedure (seefigures9a & 9b):
1. Empty both tanks.
2. Unlatch tanks from base.
3. Tilt tanks back.
4. Disconnect hoses from tanks.
5. Openupforservice.
Figure 9b
Figure 9a

Page 28 Clarke® BEXT®-100, 100H 150H, 300HV Operator's Manual
Maintenance Of The Motor
This machine has a vacuum motor that uses carbon
brushes. The carbon brushes in the motor must be
checked every three months, or every 500 hours of
operation, whichever comes first. If either of the brushes
is shorter than 3/8 inch, replace both of the carbon
brushes.
HowToCheck The Commutator And The Carbon
Brushes
WARNING: Electrical inspections must be made
by a person authorized to make
electrical repairs.
To check the commutator and the carbon brushes follow
this procedure:
1. Disconnect the power cord from the electrical outlet.
2. Empty both tanks.
3. Unlatch tanks from lower housing.
4. Lift the upper housing from the lower housing.
5. Disconnect the ground wire.
6. Remove the plastic motor cover.
7. Inspect the commutator. See figure 10. Take the
machine to a Clarke authorized repair location if you
see any of the following conditions:
a.Small holes in the surface of the commutator.
See "A" in figure 11.
b.Uneven color. Look for an even dark brown color.
Clean areas or very dark areas indicate a
problem.
See "B" in figure 11.
c. High mica. The mica insulation must be lower
than the commutator bars. See "C" in figure 11.
8. To check the carbon brush assemblies, remove the
two screws from the holding bracket.
9. Remove the brackets.
10. Remove the carbon brush assemblies.
11. Check the carbon brush assembly. Replace both
carbon brush assemblies if either carbon brush is
shorter than 3/8inch. If either brush is shorter than ½
inch, order replacement brushes. Be ready to
replace both carbon brushes earlier than the normal
inspection time.
12. Put the motor brushes in position.
13. Using the two screws, install the bracket that holds
the carbon brushes.
14. Install the plastic motor cover.
15. Connect the ground wire.
16. Install the motor holding bracket.
17. Install the lower housing to the upper housing.
