MAINT AINING THE MACHINE
To ensure optimum performance and trouble-free operation, observe the following maintenance schedule
consistently.
Daily Maintenance
• Check the water lev el; add water if necessary.
• Clean the debris screen.
Weekly Maintenance
• Remove oil and grease from the wash solution
using the DOS System (See
tem
).
• Examine spray nozzles; clean and align if necessary (See
Nozzles
• Wipe down the e xterior of the machine using spray
degreaser and a soft, damp cloth. TO PREVENT
ELECTRICAL COMPONENT FAILURE, DO NOT
SPRA Y THE MACHINE WITH WA TER.
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.
Cleaning and Aligning the Spray
).
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:
Check the water lev el indicator to 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 w ater f or 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.
Using the DOS Sys-
).
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 Belo w).

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 dr ain the w ater from the bottom 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 container.

To ensure optimum cleaning performance, it is important that you examine the spra y nozzles periodically 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 Figure
Above to maintain a proper spra y 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 abo v e .
Cleaning out the Sump
Step 1:
Remove oil from the cleaning solution using the DOS
System (See
Step 2:
Remove the debris screen.
Step 3:
Drain the wash solution from the sump chamber . T o drain
the solution either use the sump drain or a small submersible pump.
Using the DOS System
).
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/
dry vac. Dispose of the debris in accordance with applicable local, state, and feder al 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
)
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:
Heat the wash water to operating temperature, then add
appropriate amount of factory detergent.
Step 8:
Run the machine through a 15-minute wash cycle.
