Maintenance
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
figures above 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.
Using the Oil Skimmer System
The oil skimmer system is most effective if used when
the cleaning solution in the 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.
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.
Cleaning out the Sump
Filtration and Sump Sweep System
NOTE: The effectiveness of the filtration and sump
sweep system for cleaning out the sump will depend
on the type of filter bag(s) you use in the filter
canister(s). If you find that the filtration and sump
sweep systems do not adequately clean the sump on
your machine, contact your dealer or customer
service for other filter bag recommendations.
To clean out the sump using the optional filtration and
sump sweep system, perform the following procedure:
1.
If your machine is equipped with a detail sump,
dump the contents of the detail sump into the main
sump chamber.
2.
Remove oil and grease from the cleaning solution
using the oil skimmer system (See
Using the Oil
Skimmer System
).
