Section 2: Installation
BEFOREYOU 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 distributor or call a customer ser-
vicerepresentative.Whencontactingcustomerservice
please refer to the machine identification tag inside the
front cover of this manual for detailed machine specifi-
cations.
STEP 1: MAKE ELECTRICAL
CONNECTIONS
These machines are shipped with a factory-installed
power cord.To connect the machine to a power supply,
plug the cord into a grounded outlet on a single-outlet
circuit.It is important that you connect the machine to
a single-outlet circuit to avoid possible damage result-
ing from inadequate supply amperage.
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.
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 lu-
bricator on the main air supply line. Refer to the docu-
mentation provided with the power brush for more in-
formation.
Step 1:
Remove the power brush from the box, install the wire
brush in the chuck, and connect the air hose.
Step 2:
Familiarize yourself with the three-way air flow valve
(See Figure Below), then install a fitting (if necessary)
to accommodate a connection to your compressed-air
supply.
Step 3:
Connect the shop compressed-air line to the machine.
Step 4:
Connect the hose from the power brush to the air flow
valve.
Step 5:
Hang the power brush on the bracket mounted along
the right side of the machine.
STEP 3: CONNECT AWATER
LINE
This step is required for machines equipped with the
optionalautomaticwaterfillfeature.Ifyourmachinedoes
not have this option, skip this step.
The optional automatic water fill feature automatically
maintains the correct water level in the sump.The fea-
ture requires that you connect the machine to a dedi-
cated water supply line.
To connect the machine to a water supply line, attach a
suitableburst-proofhose to the hose connection on the
rear of the machine (See Figure Below), then connect

AUTOMATIC PARTS WASHER Maintenance Guide
Section 5: Maintenance and Repair
MAINTAININGTHE MACHINE
To ensure optimum performance and trouble-free op-
eration, observe the following maintenance schedule
consistently.
Daily Maintenance
• Check the water level; add water if necessary.
• Clean the debris screen.
Weekly Maintenance
• Remove oil and grease from the wash solution
using the DOS System (See Using the DOS Sys-
tem ).
• Examine spray nozzles;clean and align if neces-
sary (See Cleaning and Aligning the Spray
Nozzles ).
•Wipe downthe exteriorofthemachineusing 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 par-
ticularly stubborn soap deposits, use a soft cloth damp-
ened with warm solution from the wash chamber.
Monthly Maintenance
• Drain and clean out the sump chamber (See
Cleaning out the Sump ).
Using the DOS System
The DOS System is most effective if used when the
cleaning solution in the sump is low and cool, and after
it has been sitting for at least 30 minutes. It is best to
remove oil before you begin to use the machine each
week.
To remove oil from the cleaning solution, perform the
following procedure:
Step 1:
Checkthe water levelindicatorto ensure that the water
level in the sump is low. If the water level is not low,
drain excess water using the oil decant valve.
Step 2:
Slowly add cool water to the sump through the wash
chamber.Use a hose that reaches to the bottom of the
sump.
Note: When adding water for the purpose of removing
oil and grease, it is important that you add it slowly to
the bottom of the sump so as not to disturb the oil and
grease sitting on the top of the wash solution.
Step 3:
Open the oil decant valve and allow the fluid to run out
of the valve until there are no traces of oil, then close
the valve (See Figure Below).
Step 4:
Turn off the water flowing into the sump.
Step 5:
Allow the fluid in the oil collection container to settle for
approximately 30 minutes to allow the water and oil to
separate completely.
Step 6:
Place the container over the wash chamber and open
the water decant valve to drain the water from the bot-
tom of the container into sump.
Step 7:
Allow the fluid to run until traces of oil begin to appear,
then close the valve.
Step 8:
Dispose of the oil appropriately, then replace the con-
tainer.

Cleaning and Aligning the Spray Nozzles
To ensure optimum cleaning performance, it is impor-
tantthat youexaminethespraynozzles periodicallyand
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 Figure
Above to maintain a proper spray pattern.
Note: The spray nozzles are sized and positioned to
optimizethe distributionofcleaning solution in thewash
chamber.If you remove the nozzles make sure you re-
place them in the correct position on the appropriate
pipe. Spray nozzle specifications are stamped on the
face of each nozzle, as shown above.
Cleaning out the Sump
Step 1:
Remove oil from the cleaning solution using the DOS
System (See Using the DOS System ).
Step 2:
Remove the debris screen.
Step 3:
Drainthewashsolutionfrom thesump chamber.Todrain
the solution either use the sump drain or a small sub-
mersible pump.

Note: Manufacturer recommends that you reuse the
wash solution.To do so, transfer it to a suitable holding
container (such as a 55-gallon drum) while you clean
out the sump chamber.
Step 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 it out using a wet/
dryvac.Disposeofthedebris in accordance with appli-
cable local, state, and federal regulations.
Note: Take special care to ensure that the heating ele-
ment 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 malfunc-
tion (See LowWater Shutoff System )
Step 5:
Transfer the wash solution back to the sump chamber,
and add fresh water if necessary.
Step 6:
Replace the debris screen.
Step 7:
Heatthe washwaterto operatingtemperature,then add
appropriate amount of factory detergent.
Step 8:
Run the machine through a 15-minute wash cycle.
