These procedures are performed by a
trained service technician. The regularity of
these procedures may depend on the ma-
chine’s use.
Flush the system with a special
solution to reduce scaling (alkaline
build-up).
Use acetic acid (white vinegar) or an
anti-browning solution. Mix one quart
acetic acid with
2
gallons
(1
liters) of
hot water in the solution tank (if an
anti-browning solution is used follow
manufacturer’s instructions). Turn on
the
switch and allow the
machine to run over a floor drain until
the solution tank is empty
(approximately once a month).
Inspect hoses and cords, replace as
needed.
Inspect filter screens, clean or replace
as
needed.
inspect spray pattern
of
jets, replace or
clean
as
needed.
Check the tension of the solution valve
cable, tighten
if
necessary.
Inspect the
motor, remove any lint
build-up at cooling intake, service
carbon
motor brushes
(Approximately every 750
operation hours).
With the machine running, the brush
should rotate freely without rattling or
grinding. Replace bearings
if
necessary.
CAUTION:
Do
not allow this machine to remain in a
vehicle or area where the temperature
will
be below
Allowing this
machine to freeze
will cause damage not
covered by the
6-3-1
warranty.
CAUTION:
Protect this machine from freezing
if
it
becomes necessary to store it at temper-
atures below
Use a methyl hydrate window washer type
anti-freeze; mix a gallon or
two
(4-8
liters)
of
anti-freeze solution, following the manufac-
turer’s instructions. Add the anti-freeze
solution to the solution tank. With the hoses
in place run the machine until the anti-freeze
begins spraying out (don’t empty solution
tank). Vacuum out the remaining anti-
freeze solution in the solution tank. Discon-
nect the hoses and empty the recovery buck-
et. Always allow the unit to return to room
temperature before filling with hot water or
operating.
CAUTION:
Do
not use Ethylene Glycol
or
any
cooling system anti-freezes.
