Maintenance
CAUTION: Use protective gloves, goggles,
footwear and any other protective clothing required
by law for detergents mixed with the waste stream.
The SJ-15 does not require a lot of maintenance, but it
does require consistent maintenance. The frequency of
maintenance varies depending on what is in the water.
General maintenance consists of removal of sludge
from the bottom of the wash tank and removal of any
floating oil in the wash tank.
WARNING: Shut down the SJ-15 and allow it to cool
before performing any maintenance. Do not allow
pump to run longer than 5 minutes without water.
Disconnect all hoses to allow water to drain.
Oil Removal
If you have floating oil in the tank that needs to be
removed, shut down the SJ-15 and let the oil float to the
top. Remove the chip trays and use oil absorbing
sponges (#21-185) which will absorb only oil. To re-use
the sponge, wring out the oil that is in the sponge into a
container. Oil can be removed automatically when you
have the skimmer.
Sludge Removal
Remove the lower 1-1/2” pipe cap on the side of the
machine allowing all of the water to escape. Use a
small shovel to remove the residual sludge from the
bottom of the tank. Removing the sludge and cleaning
the floor will greatly increase the life of the heating
element.
CAUTION: Disposal of contaminated water must
comply with local and federal EPA regulations.
Spray Arm
The spray nozzles should be checked regularly for
obstruction and cleaned by removing and inserting a
probe. The spray arm nozzle angle on both spray arms
should be mounted in the same direction. The spin pin
o-rings should be replaced annually.
Filters
With the tank empty, clean the suction pump strainer.
Clean when pressure gauge reads a 10 PSI decrease
from start up pressure.
Detergent and Additives
Manufacturer's detergents are the only detergents
approved for use with our automatic 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 approximate concentration of 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 concentration under typical condi-
tions, add detergent each month after cleaning the
sump chamber. Follow recommended detergent quanti-
ties. Use a 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.
