INTRODUCTION
The Zep 430 is a fully self-contained, portable carpet extractor system.
It has a 60 psi solution pump and a two (2) jet spraying system to apply solution to the carpet.
A rotatingbrushisdrivenbyacoggedbeltsystematapproximately1000RPM’s. Thisbrushprovidesaveryaggres-
sive agitation of the solution into the carpet fibers to loosen ground-in dirt. The chevron pattern of the brush bristles
channelsthe dirty water to the center ofthe 12” aluminum vacuum head for betterextraction.
The two-stage vacuum motor on the Zep 430 is capable of 80 inches of water lift. This unit extracts virtually all of the
dirty solution from the carpet fibers, which dramatically reduces drying time.
The Zep 430 is a very “user friendly” machine. All controls are located at the top of the handle grips, literally at your
fingertips. The 430 has a 4 gallon solution tank and a 3 gallon lift out recovery tank.
This machine must be grounded. If it should malfunction or break
down, grounding provides a path of least resistance for electric
currenttoreducethe riskof electricshock. This machineis equipped
with a cord having an equipment-grounding conductor and ground-
ing plug. The plug must be inserted into an appropriate outlet that
is properly installed and grounded in accordance with all local
codes and ordinances.
WARNING - Improper connection of the equipment-grounding con-
ductor 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 machine - if it will not fit the outlet, have a proper outlet installed
by a qualified electrician.
This machine is for use on a nominal 120-volt circuit, and has a
grounded plug that looks like the plug illustrated in figure A. A
temporary adapter that looks like the adapter illustrated in figures B
and C may be used to connect this plug to a 2-pole receptacle as
shown in figure B if a properly grounded outlet is not available.
The temporary adapter should be used only until a properly
grounded outlet (figure A) can be installed by a qualified electri-
cian. The green colored rigid ear, lug, 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.
NOTE: In Canada, the use of a temporary adapter is not permitted
by the Canadian Electrical Code
EXTENSIONCORDS
Use only three-wire 14/3 or larger gauge approved extension
cords that have three-prong grounding type plugs and three-pole
receptacles that accept the appliance’s plug. Replace or repair
any damaged cords or plugs.
When servicing, refer to authorized person only. Use only identi-
cal replacement parts.

the training given by your supervisor. Failure to
do so can result in personal injury and/or damage
to machine and property!
DONOTOPERATE MACHINEINAN EXPLOSIVE EN-
VIRONMENT!
NEVERUSE THIS MACHINE TOPICK UPVOLATILE
OREXPLOSIVE MATERIALS!
The model shown in this manual is intended for com-
mercial use.
PREPARATION
1. Check power cord, plug and strain relief for worn or
damaged insulation. Repair or replace if necessary.
2. Confirm the quick connects located at the back of the
machine are properly attached. This is the water sup-
ply line and solution water will not be allowed to flow
through to the jets if this connection isn’t secure.
3. Lock the brush assembly in the up position for stor-
age or transport. This is done by pulling up on the
black knob/lift mechanism at the front of the machine
and allowing the lift stop to rest on the bracket.
4. Inspect the vacuum head and brush by tilting the ma-
chine backwards.
a) Vacuum Head: Check for any damage. Burrs on
the contact surface may snag carpet fibers.
Gouges, scratches and chipped areas can reduce
vacuum performance.
b) Brush: Inspect for damaged or missing bristles,
replace if necessary.
Return the machine to the upright position.
OPERATION
The following procedures are intended to describe and
detail proper operation of your machine. Failure to follow
these recommended procedures can reduce the machine’s
performance and may result in damage to the machine.
1. Vacuum the area to be cleaned. Your machine will do
a more thorough job if the loose dirt and debris are
removed before the extraction process begins.
2. AddNON-FOAMINGcleaning concentratetothe fresh
water/solution tank. Follow mixing instructions for 3
to 3-1/2 gallons of water. Then fill the tank with warm
water using the faucet/power fill adaptor. Donotuse
water hotter than 60°C (140°F).
Or, you may mix the concentrate with 3 to 3-1/2 gallons
of clean water in a CLEAN bucket, then pour the mix-
ture into the solution tank.
DONOTOVERFILL.
NEVERUSETHERECOVERYTANK’SDIRTY
WATER TOFILLTHESOLUTION TANK!
3. Ensure the water supply hose connection at the rear
of the machine is secure.
4. Connect the power cord plug to a 115 volt grounded
wall socket. See Grounding Instructions. Use of an
extension cord is not recommended. However, if one
is necessary, use only a 14 gauge or larger cord.
Smaller or inferior cords are dangerous and may cause
damage to your machine.
5. Lower the brush assembly by lifting theblack knob off
the storage/transport bracket.
6. Turn on the vacuum switch at the control panel to
start the vacuum motor.
Note: The accessory pump switch is for use only with
theaccessory tools. See“OPERATINGWITHACCESSORY
TOOLS”.
7. Pull backward during operation. DONOTATTEMPT
TO OPERATE INAFORWARD DIRECTION. Position
yourself behind the machine, grasp the handle and
depress the red momentary “Pump/Brush” switch
on the top center of the handle. This switch activates
the brush drive motor and the pump to spray cleaning
solution. Walk slowly backward and continue to de-
press the red switch to perform the cleaning process.
5. Check the inlet screen and filter bag in the opening
of the fresh water/solution tank for damage or debris.
Holes in the screen can allow contaminants to enter
the pump resulting in costly repairs. A clogged
screen will reduce pump performance and may
cause permanent damage.
6. Remove the clear dome on top of the recovery tank.
a) Inspect for damage to the dome and gasket.
Dirt or debris on the gasket or sealing surface of
the tank can cause a vacuum leak and reduce
vacuum performance.
b) The intake filter screen should be clean of
debris and checked periodically for any damage,
replace if necessary.
Return the cover to its original position.
4

After Each Use:
1. Clean the dome top, intake filter screen, gasket and
recovery tank with fresh, clean water. Do not reinstall
the dome until the next use, this will allow the recovery
tank to dry out.
2. Flush the solution tank and inlet screen with clean
water. Vacuum all water out using the Power Fill adap-
tor.
3. Remove any debris on the scrub brush, vacuum head
and around the spray jets.
5. Make sure the brush assembly lift lever is locked in the
raised position.
6. Store your machine in a dry, protected area. Do not
expose this machine to rain, standing water or freez-
ing temperatures.
Periodically:
Aftercontinuous or repeateduse the jets and check valves
will need cleaning: Unplug the cord and empty the recov-
ery and solution tanks. Tilt the machine backward. Re-
move the jet caps, jets and check valves shown in the brush
assembly illustration and soak in white vinegar until visible
deposits are dissolved, then scrub with a soft bristle brush.
Note: jets and check valves should be replaced once a
year, because they tend to erode under extended use. This
may cause overuse of solution and streaking.
8. Release the red button approximately 6 inches be-
fore completing each pass. The spray jets are lo-
cated behind the vacuum head making it necessary to
pull the machine a few inches further to pick up the last
amount of solution dispensed onto the carpet.
9. Tilt the machine back on the rear wheels and walk
forward to position the machine along side the previ-
ous pass (slightly overlapping).
10. As dirty solution is recovered, some foaming may be
noted. Excessive foaming can be counteracted with
liquid defoamer applied according to the chemical
manufacturing directions. Do not allow foam to rise
into or near the dome; this will harm the vacuum
motor. Use defoamer or empty and flush the recovery
tank.
11. To empty the recovery tank, remove the dome as-
sembly and lift the tank out. Dispose of the recovered
water properly.
12. If streaking occurs after a period of operating time,
thismeans the solution (freshwater) tankisnear empty.
Streaking is eliminated by adding more water and
chemical solution to the tank. Empty the recovery
tank every time you fill the solution tank.
13. Toempty the solutiontankconnectthePowerFilladap-
tor to the vacuum inlet on the front of the dome. Turn
the vacuum switch on.

The Zep 430 self-contained extractor is designed and
manufactured to provided years of trouble free service with
a minimum of maintenance and service. The following
recommendations are intended to assist the operator and
Service Technician in performing routine maintenance.
WARNING: Always unplug your machine before perform-
inganyservice. Severepersonalinjurycouldresult if the
electrical power is not disconnected.
OPERATING WITH ACCESSORY TOOLS
1. To use an accessory tool disconnect the supply hose
at the rear of the machine and connect the accessory
tool hose .
2. Next, disconnect the machine’s vacuum hose from
the front of the dome assembly and connect the ac-
cessory tool vacuum hose to the dome.
3. Turn the vacuum and accessory pump switches on.
Solution will be dispensed while the accessory tool
trigger is depressed.
Watch the dome to make sure the recovery tank does
not overflow.
Note: The pump motor is equipped with an automatic ther-
mal protection device. If the motor overheats for any rea-
son, the thermal protector will activate and automatically
turn the motor off. If this occurs the operator should turn the
manual pump switch to the off position and allow approxi-
mately fifteen minutes for the motor to cool. When the
motor has cooled to a safe operating temperature, the ther-
mal protector will automatically close and allow power to
be supplied to the motor via the manual pump switch. The
operator will be able to resume normal operation. If the
pump motor shuts down repeatedly, it should be checked
at anAuthorized Service Center.

Followthisprocedure: Remove acorn nut and thru-bolt from brush chassis lifthandle. Gentlytiltmachinebackwards.
While holding the base of the brush housing with one hand, release the lift handle from the up/locked position. The
brushhousing pivots on a hingethatdoesn’tneed to be removed. Loosen the twomotorbracketmounting bolts with a
7/16”wrench. DO NOTREMOVETHEBOLTSUNLESSYOUARE REPLACINGTHE MOTOR. Slidethe motoraway
from the brush to tighten the belt or toward the brush to remove. If you are replacing the belt it will be necessary to
removethebrushassembly to install a new one. Remove the two axle shaft retaining screws located oneithersideof
thebrushhousing. Loop belt over cog and reinstall brush.
Unlike a “V” type belt, the cogged belt is run with basically zero deflection. To test the belt tension, hold the belt
between your thumb and forefinger and twist to the side. It should turn approximately 90°with little effort. If it twists
morethan 90°, retighten the belt.
