Cleaning Solutions; Maintenance - U.S. Products KING COBRA 500-CSA Information & Operating Instructions

INSPECTION:
Carefully unpack and inspect your KING COBRA-500 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. 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 5 and 10 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. 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. The pump may
require rebuild kits after 1000 - 1500 hours, typically, and the pump unloader valve may need to be replaced
after approximately 1000 - 1500 hours of use (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.
