Operations
Installation
Before You Begin
To prepare to install the machine, choose an unob-
structed, level site that allows convenient access for
operators and maintenance personnel. Sources for
water and electrical power should be located near the
installation site. If your machine is equipped with the
optional power brush and hand detail brush you
must also run a compressed air line to the
installation site.
If you have any questions regarding the installation,
please contact your dealer and have the machine iden-
tification number available for the dealer to reference.
Your machine identification tag is located inside the
front cover of this manual for detailed machine specifi-
cations.
Step 1: Make Electrical Connections
NOTE: All electrical installation tasks must be
performed by a licensed, professional electrician to
ensure safe and proper operation. The installation
must comply with the National Electric Code and all
applicable state and local codes.
The machine can only operate on the type of electrical
power indicated on the machine identification tag. Read
and understand the machine identification tag to
determine the electrical power requirements before
installing the machine.
Step 2: Connect A Compressed-air Line
And Accessories (Optional)
This step is required for machines equipped with
the optional power brush and hand detail brush.
If your machine does not have these options,
skip the following procedure.
NOTE: To ensure proper operation and to minimize
the possibility of premature component failure, make
sure the compressed air is supplied at 75 to 90 psi.
We also recommend an in-line moisture trap and
an in-line lubricator on the main air supply line.
Refer to the documentation provided with the power
brush for more information.
1. Remove the power brush from the box, install the
wire brush in the chuck, and connect the air hose.
2. Familiarize yourself with the three-way air flow
valve, then install a fitting (if necessary) to accom-
modate a connection to your compressed-air
supply.
3. Connect the shop compressed-air line to the
machine.
4. Connect the hose from the power brush to the air
flow valve.
5. Hang the power brush on the bracket mounted
along the right side of the machine.
Step 3: Connect A Water Line
This step is required for machines equipped with the
optional automatic water fill feature. If your machine
does not have this option, skip this step.
The optional automatic water fill feature automatically
maintains the correct water level in the sump. The
feature requires that you connect the machine to a
dedicated water supply line.
To connect the machine to a water supply line, attach a
suitable burst-proof hose to the hose connection on the
rear of the machine, then connect the hose to a nearby
water spigot.
NOTE: The machine is designed for portability, and
some maintenance tasks require that you move the
machine. DO NOT make a permanent connection
from your shop water supply to the machine.

Step 4: Fill The Machine With Water And
Add Detergent
1. Familiarize yourself with the low water shut-off
system on the left side of the machine.
2. Fill the sump with water.
If your machine is equipped with the optional
automatic water fill feature, simply turn the water
on; the automatic water fill feature will automati-
cally turn off the water when the sump is full.
If your machine is not equipped with optional
automatic water fill feature, add water through the
wash chamber until the low water shut-off system
indicates that the sump is full. The sump capacity
is 25 gallons.
3. Close the lid.
4. Flip the heater switch to the ON position.
The sump water will reach operating temperature
(160°-180°F Excludes 120V Version 1.043-356.0)
in approximately four hours.
To avoid having to wait for the wash solution to
heat up before you use the machine each day,
install an optional 24-hour 7-day heater timer.
Refer to 24-hour, 7-day Heater Timer for more
information.
IMPORTANT: Allow the sump water to reach
operating temperature before adding detergent
and running the machine. If you add detergent and
run the machine when the sump water is cool, the
detergent will foam excessively and could overflow
the machine.
5. While the sump water is heating, add the appro-
priate quantity of factory approved detergent to the
wash chamber. We recommend mixing the
detergent with warm water in a separate bucket/
container and then pouring the dissolved detergent
into the sump.
NOTE: Factory approved detergent is the only
detergent approved for use with this automatic parts
washer. It is specially formulated with rust inhibitors
and anti-foaming agents to optimize performance and
minimize maintenance. The use of any other
detergent during the warranty period will void the
warranty. In addition, using factory detergents will
extend your 90 day labor warranty to 1 year.
6. Turn the wash cycle timer and allow the machine to
complete the cycle to dissolve the detergent into
the water. When the machine stops, it is ready for
use. Refer to Operation for complete operating
instructions.

Main Operating Components
Familiarize yourself with the main operating compo-
nents before operating the machine.
Control Panel
The control panel is located on the front center of the
lid. It contains the heater, wash cycle, turntable
controls, and low water indicator.
Low Water Indicator
The low water indicator light illuminates if the wash
solution in the sump is low. For more information refer
to Low Water Shut-off System.
Turntable Switch
The turntable switch is an illuminated rocker switch that
enables you to disconnect power tothe turntable motor.
Set to ON, the turntable rotates during the wash cycle.
Set to OFF, the turntable does not rotate during the
wash cycle. The switch is useful for washing large parts
that would otherwise impede turntable rotation.
Heater Control
The heater control is an illuminated rocker switch. It
controls the heating element in the sump chamber. The
heater control illuminates when the heating system is
on. The heating system is thermostatically set at the
factory to reach a high temperature of 180 °F (Excludes
120V Version 1.043-356.0). The temperature is adjust-
able using the thermostat (See Thermostat).
NOTE: The machines contain an internal power relay
that automatically disconnects power to the heater
when the pump turns on; the heater and pump cannot
run simultaneously (120V only). After long wash
cycles it may be necessary to let the machine sit idle
for a period of time to allow the wash solution to
reheat to operating temperature.
Wash Cycle Control
The wash cycle control is a timer switch. When set, the
timer automatically shuts off the pump and turntable
when the wash cycle is complete.
Thermostat
The thermostat is located inside pump enclosure. The
thermostat is factory-set to heat the wash solution to a
maximum temperature of 180°F (Excludes 120V
Version 1.043-356.0).
Adjusting the Thermostat
To adjust the thermostat, rotate the adjustment screw
or knob clockwise to increase the temperature, or coun-
terclockwise to decrease the temperature.
24-hour, 7-day Heater Timer
A 24-hour, 7-day heater timer is available as an option
on these machines. The timer plugs directly into a 15-
amp outlet and automatically cycles the heating system
on and off each day. To configure the timer, refer to the
instructions printed on the back of the timer housing.
To order a 24-hour, 7-day heater timer, contact your

Operations
Turntable Assembly
The turntable assembly uses a torque arm mounted on
the underside of the lid to rotate the turntable. The
torque arm includes a torque limiter which prevents the
turntable motor from burning out in case a part falls off
the turntable and obstructs rotation. For information on
adjusting the torque limiter, refer to Torque Limiter. For
information on replacing the turntable motor, refer to
Turntable Motor.
Removing the Turntable
To remove the turntable, grasp it evenly on opposite
sides and lift it free of the spindle.
Important: The turntable rotates on a thrust bearing
inside of the hub. As you lift the turntable free of the
spindle, take care not to jar the thrust bearing loose. If
the thrust bearing drops out of the hub, inspect it for
wear then either replace it or re-install it.
Debris Screen
The debris screen is located below the turntable inside
of the wash chamber. The debris screen continuously
filters debris particles from the cleaning solution to
ensure blockage free spray nozzle operation, and also
provides a safeguard against small parts that might
accidentally be washed through from the wash
chamber.
The frequency at which you must clean the debris
screen depends on machine usage. In general, you
should clean the screen before operating the machine
each day. To access and remove the screen you must
remove the turntable (see Removing the Turntable).
NOTE: Never operate the machine without the debris
screen in place. The screen is specially sized to filter
particles that could clog the spray nozzles or damage
the water pump. Operating the machine without
the debris screen in place could cause spray
nozzle clogging or water pump failure.
Air Flow Valve (Optional)
The air flow valve is located on the right rear corner of
the machine. It is a three-way ball valve that controls
the flow of compressed air to the power brush and the
hand detail brush.
Power Brush (Optional)
The power brush is located on the right front corner of
the machine. Refer to Connect a Compressed-Air
Line and Accessories for detailed installation informa-
tion.

to 5 gallons of water per day to evaporation. It is
important that you monitor and maintain the water level
daily to minimize the risk of burning out the heating
element or ruining the pump.
NOTE: Add detergent each time you add water. Add
detergent after you clean the sump chamber each
month, and more frequently if your cleaning cycle
maintenance period is more frequent, and if you
notice specific low-detergent indicators (See
Detergents and Additives).
Low Water Shut-off System
The low water shut-off system shuts down the machine
if the wash solution in the sump chamber drops below a
safe level. The system uses two reed switches and a
float rod mounted on the right outer wall of the sump
chamber to control the water level.
If the wash solution drops below the lower reed switch,
the low water indicator light on the control panel turns
on and the system disconnects power to the heating
element, the pump, and the turntable motor. To reset
the system, add water to the sump until the low water
indicator light turns off.
Automatic Water Fill (Optional)
The automatic water fill system automatically maintains
a proper water level in the sump. It is available as on
option on these machines.
The automatic water fill system uses the low water
shut-off reed switches to open and close a water
solenoid valve, which automatically maintains a proper
water level in thesump. The figure above describes the
operation of the automatic water fill system.

Detergents And Additives
Detergents
Manufacturer's detergents are the only detergents
approved for use with ourAutomatic Parts washers.
They are specially formulated with rust inhibitors and
anti-foaming agents to optimize performance and
minimize maintenance. The use of any other detergent
during the warranty period will void the warranty. To
monitor the relative concentration of the detergent in
the wash solution, periodically examine the wash
solution in the sump chamber for the following
indicators:
•Rust inside the machine: not enough
detergent
•Excessive foaming: not enough detergent
•Thick, white residue on parts after washing:
too much detergent
To maintain proper detergent concentration under
typical operating conditions, add detergent each month
after cleaning the sump chamber. Follow recom-
mended detergent quantities. Use pH kit to determine
the proper amount of detergent to use. If you need help
interpreting test results, contact customer service.
Rust Inhibitor Additive
Factory detergents protect the entire inside of your
machine against the degenerative effects of water
evaporation. A rust inhibitor additive actually evapo-
rates with the water and continuously coats and
protects metal surfaces, even while your machine is
sitting idle. For more information, contact your dealer or
call customer service.
Preparing The Machine For Use
Before you begin to wash parts, it is important that you
properly prepare the machine. Before you begin to use
the machine each day:
• check the water level and add water to the
sump tank if necessary;
• heat the water to operating temperature
• add detergent if necessary (see Detergents
and Additives);
• verify that none of the spray nozzles are
clogged; and
• clean the debris screen.
Washing Parts
The following procedure assumes that the heater is on
and the sump water is at operating temperature.
To wash parts, perform the following procedure.
WARNING: Hot, high-pressured cleaning solution
could cause serious injury. Always wear rubber
gloves and approved eye protection when loading
and unloading the machine.
1. Load large, heavy parts directly onto the turntable.
Load small, light parts in the small parts basket, if
available. Make sure none of the parts extend
beyond the edge of the turntable and make sure
large, light parts (valve covers, for example) are
secured to the turntable.
NOTE: For optimum cleaning performance, provide a
slight clearance between parts to allow adequate flow
of cleaning solution around and between them.
2. Close the lid.
NOTE: If you are washing large parts that might
impede turntable rotation, flip the turntable switch
OFF.
3. Set the wash cycle timer.
4. When the machine stops, lift the lid and wait a few
moments to allow the parts to cool and dry before
removing them. Most parts flash-dry in seconds.

Operations
Using the Oil Skimmer System
The oil skimmer system is most effective if used when
the cleaning solution inthe sump is cool.The frequency
at which you must remove the oil from the wash
solution will depend on machine usage. Under typical
operating conditions you may need to remove the oil
every day. If the oil skimmer runs longer than 10-15
minutes, the detergent and vapor rust inhibitor content
in the sump should be checked. The detergent and
inhibitor can be removed with extensive use of the
skimmer, so be certain to check chemical levels after
running the skimmer to determine if you require a
higher frequency chemical maintenance cycle than
weekly.
IMPORTANT: The skimmer motor is equipped with a
thermal overload switch which protects the skimmer
from overheating. If you attempt to use the oil skimmer
system when the wash solution is hot, the thermal
overload will probably trip and the motor will shut off
until it cools. Under normal skimming conditions (when
the wash solution is cool) the thermal overload should
not trip.
To remove oil from the cleaning solution, perform the
following procedure:
1. Allow the machine to sit idle for at least 30 minutes
to allow the oil to float to the surface of the wash
solution.
2. Ensure that the oil collection container is in place,
then turn the skimmer switch to the “ON” position.
3. Allow the oil skimmer to operate until it is no longer
extracting oil from the cleaning solution.
Tip: While extracting oil from the cleaning solution, oil
will flow off the wiper blades in a fine continuous
stream. Water will flow off the blades in droplets. Once
droplets begin to flow off the wiper blades, stop the
skimmer motor.
4. Dispose of the oil in the collection container in
accordance with local and state regulations, then
replace the container.

Maintenance
Maintaining The Machine
To ensure optimum performance and trouble-free oper-
ation, observe the following maintenance schedule
consistently.
Daily Maintenance
• Check the water level; add water if necessary.
• Clean the debris screen.
Weekly Maintenance
•Detergent Concentration Level: Check
detergent level weekly to maintain concentra-
tion level, which decreases when water is
added. The pH level of this detergent must be in
accordance with the detergent manufacturer's
recommendation.
• Remove oil and grease from the wash solution
by using the oil skimmer.
• For oily or extremely soiled parts, it is recom-
mended the oil skimmer be operated on a more
frequent basis.
• Examine spray nozzles; clean and align if
necessary (See Cleaning and Aligning the
Spray Nozzles).
• Wipe down the exterior of the machine using
spray degreaser and a soft, damp cloth. TO
PREVENT ELECTRICAL COMPONENT
FAILURE, DO NOT SPRAY THE MACHINE
WITH WATER.
NOTE: Degreaser spray and a damp cloth will
usually remove all dirt and grime from the machine.
For particularly stubborn soap deposits, use a soft
cloth dampened with warm solution from the wash
chamber.
Monthly Maintenance
• Drain and clean out the sump chamber
(See Cleaning out the Sump).
Cleaning and Aligning the Spray Nozzles
To ensure optimum cleaning performance, it is
important that you examine the spray nozzles periodi-
cally and clean and align them if necessary. To clean a
plugged nozzle, remove it from the spray pipe and use
a small wire brush to free the nozzle of any obstruc-
tions. When you replace the nozzle on the spray pipe,
make sure you align it according to figure to maintain a
proper spray pattern.
NOTE: The spray nozzles are sized and positioned to
optimize the distribution of cleaning solution in the
wash chamber. If you remove the nozzles make sure
you replace them in the correct position on the
appropriate pipe. Spray nozzle specifications are
stamped on the face of each nozzle, as shown.

Maintenance
Cleaning out the Sump
1. Remove oil from the cleaning solution using the oil
skimmer.
2. Remove the debris screen.
3. Drain the wash solution from the sump chamber.
To drain the solution either use the sump drain
or a small submersible pump.
4. Remove sand and other debris from the bottom of
the sump chamber. To remove the debris either
flush it out through the sump drain, or vacuum itout
using a wet/dry vac. Dispose of the debris in accor-
dance with applicable local, state, and federal
regulations.
NOTE: Take special care to ensure that the heating
element and the low-water float are free of debris.
A build up of debris around the heating element will
decrease heating performance and may cause the
element to overheat and fail.A build up of debris
around the float may cause the low water shut-off
system to malfunction (See Low Water Shutoff
System)
5. Replace the debris screen.
6. Heat the wash water to operating temperature,
then add appropriate amount of factory detergent.
7. Run the machine through a 15-minute wash cycle.
Repairing The Machine
