U.S. Products COBRA PLUS-300, Information & Operating Instructions

INSPECTION:
Carefully unpack and inspect your  COBRA PLUS-300 for shipping damage.  Each machine is tested and
inspected before shipping.  Any shipping damage incurred is the responsibility of the carrier.  You should notify
the carrier immediately if you notice damage to the box or to the machine or parts.

CLEANING SOLUTIONS:
We recommend liquid cleaning chemicals, such as our Magic Fabric Cleaner.  Powder chemicals may be used,
but unless mixed very thoroughly they could cause a build-up in the pump, lines, heat exchanger and/or
quick disconnects.  Any problem caused by a chemical build-up is not covered by warranty.  Use a neutral
cleaner with a pH between 6 and 9 to avoid premature wear of the pump, seals, and/or other components.
Damage caused by the use of strong chemicals is not covered by the warranty.

MAINTENANCE:
For optimum performance flush the machine with clear water at the end of each working day.  Once a
month, minimum, run a flushing compound  through the machine to break up any mineral or chemical build-
up that may have formed.  U.S. Products “X-1500” is recommended.  The vacuum motor, pump motor, and
the pump do not require any scheduled maintenance; however, the motors may require replacement brushes
after 1000 - 1500 hours, and the pump and bypass valve may require rebuild kits after 1000 - 1500 hours,
typically (refer to machine part list for numbers)  Clean the body with an all purpose detergent, and protect it
with an automobile interior polish.  Lubricate the wheels, castors, and quick disconnects with an all purpose
silicone spray.
