Operations
Installation
Read and understand this entire section before you
install your machine.
If you have any questions regarding the installation,
please contact your dealer or call a customer service
representative. When contacting customer service
please refer to the machine identification tag inside the
front cover of this manual for detailed machine specifi-
cations.
Before You Begin
To prepare to install your new automatic parts washer,
choose an unobstructed, level site that allows conve-
nient 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
installing site.
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
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.
To ensure proper operation and to minimize the possi-
bility of premature component failure, make sure the
compressed air is supplied at 75 to 90 psi. It is also
recommended that an in-line moisture trap and an in-
line lubricator be installed on the main air supply line.
Refer to the documentation provided with the air 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
select valve (See Figure Below) then install a fitting
to accommodate 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 select valve.
5. Hang the power brush on the bracket mounted
along the right side of the machine.

Step 3: Fill the Machine With Water
1. Familiarize yourself with the water level indicator
light on the control panel.
2. Open the right sump cover and feed a water hose
directly into the sump chamber
3. Fill the sump with water. The sump capacity is 50
gallons.
4. When the low water level indicator light turns off,
the sump is full. Turn off the water.
NOTE: Monitor the water level carefully - do not
overfill the machine. If you overfill the machine,
remove excess water using a small submersible
pump or a suitable container. The correct water level
is two inches from the top of the access door when
the pump is off.
5. Close the lid.
6. Turn the heater timer to the 2 hour position. The
sump will reach operating temperature (160°-
180°F) in approximately one hour.
7. 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.
8. Close the lid.
9. Turn the wash cycle timer to 2 hours for the first
time and allow the machine to complete the cycle
to thoroughly dissolve the detergent into the water.
When the machine stops (andafter the wash water
reaches operating temperature), it is ready for use.
Refer to Operation for complete operating instruc-
tions.

Operations
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
and it contains the controls for the heater, wash cycle,
oil skimmer, turntable and low-water indicator light.
Heater Control
The heater control is a 12-hour timer switch. It controls
the heating element in the sump chamber. The heater
control is thermostatically set at the factory to reach a
high temperature of 180°F. The temperature is adjust-
able using the thermostat (See Section on Thermostat
for Illustration).
Wash Cycle Control
The wash cycle control is a 60-minute timer switch with
a hold feature. When set between 1 and 60 minutes,
the timer automatically shuts off the pump and turntable
when the wash cycle is complete. When set to hold,
the pump and turntable run continuously until manually
shut off.
Oil Skimmer Control
The oil skimmer control is a 30-minute timer switch that
controls the automatic oil skimmer system.
Turntable Switch
The turntable switch is a simple 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.
Low Water Indicator
The low water indicator light illuminates if the wash
solution in the sump is low.
Lid Safety Switch
The lid safety switch is located on the front edge of the
cleaning chamber. This feature ensures that the water
pump and turntable motor do not operate if the lid is
open or unsecured. The safety switch is adjustable.
Adjusting the Lid safety Switch
To adjust the safety switch, remove the control panel,
adjust the switch and replace the control panel. When
properly adjusted, you should hear a slight ‘click’as the
lid closes.
Thermostat
The thermostat is located inside the heating element
and thermostat enclosure.The thermostat is factory set
to heat the wash solution to a maximum temperature of
180°F.
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.

Operations
Debris Screen
The debris screen is located just below the wash
chamber and is accessible from the front of the
machine. The debris screen continuously filters debris
particles from the cleaning solution to ensure blockage-
free spray nozzle operation and also provides a
safeguardagainstsmallpartsthatmightaccidentallybe
washed through from the cleaning 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.
NOTE: Never operate the machine without the debris
screen in place and never remove the screen while
the machine is operating. 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.

Water Level
Under typical operating conditions the machine loses 3
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).
Automatic Water Fill
The automatic water fill system automatically maintains
a proper water level in the sump. It is available as an
option on model H2O-2518 machines.
The automatic water fill system uses the low-water
shut-off proximity switches to open and close a water
solenoid valve, which automatically maintains a proper
water level in the sump. The figures below describe the
operation of the automatic water fill system.

Operations
Detergents & 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 distrib-
utor 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;
• 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.
1. Load large, heavy parts directly onto the turntable.
Load small, light parts in the small parts basket
provided with your machine. 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.
3. Set the wash cycle timer to between 1 and 60
minutes for a timed wash cycle, or set it to Hold for
a continuous wash.
4. When the machine automatically stops (or after
you manually stop the wash cycle), open the lid
and wait a few moments to allow the parts to cool
and dry before removing them. Most parts will
flash-dry in seconds.
Using the Oil Skimmer
The oil skimmer is most effective if used when the
cleaning solution is cool, and after it has been sitting for
at least thirty minutes. Thefrequency at which you must
remove the oil from the wash solution will depend on
machine usage. Under typical operating conditions you
can expect to remove the oil once each week.
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.
Cuda 2518 Operator’s Manual 8.915-630.0 -AM

Maintenance
2. Ensure that the oil collection container is in place
(See Figure Below), then turn the skimmer switch
to the 30-minute 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 of the wiper blades, stop the
skimmer motor.
4. When the skimmer motor stops, dispose of the oil
in the collection container in accordance with local,
state and federal regulations, then replace the
container.
Shutting Down The Machine
To shut down the machine at the end of the day:
• set the wash cycle timer to OFF;
• set the heater timer to OFF;
• set the oil skimmer to OFF;
• shut off the compressed air at the supply line
(if installed).
WARNING: If the heater is left unattended, the
water could evaporate and the oil and grease in the
wash chamber could catch fire.
For periods of extended shut-down, disconnect all
power to the machine.
Maintenance and Repair
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 thisdetergent must be in
accordance with the detergent manufacturer's
recommendation.
• Remove oil from the wash solution using the oil
skimmer system (See Using the Oil Skimmer
System).
• Examine the spray nozzles; clean and align if
necessary (See Cleaning and Aligning the
Spray Nozzles).
• To maintain the integrity of the exterior finish,
wipe down the exterior of the machine using a
spray degreaser and a soft, damp cloth. TO
PREVENT ELECTRICAL COMPONENT
FAILURE, DO NOT SPRAY THE MACHINE
WITH WATER.
NOTE: Spray degreaser 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).
Semi-Annual Maintenance
• Lubricate the pivot on the turntable motor
assembly with machine oil or anti-seize.
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 obstructions. When you replace the nozzle on the
spray pipe, make sure you align it according to the
following diagram to maintain a proper spray pattern.

Maintenance
NOTE: The spray nozzles are positioned to optimize
the flow and 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.
Cleaning out the Sump
1. Remove oil from the cleaning solution using the oil
skimmer system.
2. Remove the turntable and the debris screen. To
remove the turntable, slide the chain up from
around the perimeter of the turntable, then pull up
evenly on the turntable to remove it from the center
pin
NOTE: When you remove the chain from the
turntable, be sure to maintain some chain tension to
ensure that the chain does not disengage from the
drive pulley.
3. Drain the wash solution from the sump chamber.
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 regu-
lations.
NOTE: Take special care to ensure that the heating
element is free of debris. A build up of debris around
the element will decrease heating performance and
may cause the element to overheat and fail.
5. Refill the sump with clean water.
6. Replace the debris screen and turntable. To
connect the drive chain to the turntable see the
figure below.
7. Heat the wash water to operating temperature,
then add 10 scoops (20 cups) of detergent for
