Maintenance
Maintenance, replacement or repair of emission
control devices and systems may be performed by
any repair establishment or individual; however,
warranty repairs must be performed by a dealer or
service center authorized by Maruyama
Manufacturing Company, Inc. The use of parts that
are not equivalent in performance and durability to
authorized parts may impair the effectiveness of the
emission control system and may have a bearing on
the outcome of a warranty claim.

After the pump has been used with muddy water,
be sure to run it with clean water for a few minutes
to clean the interior of the pump before stopping
operation.

Where outside temperatures drop to freezing or
below, be sure to drain all water from the pump

a dry, cool, dark place.
