4.2 PERIODIC MAINTENANCE
A scheduled maintenance program should be estab-
lished and maintained. Such a program, if adhered
to diligently, will provide added assurance that the
power system functions properly when it is needed.
Keeping a “Maintenance Log” is highly recommended.
Such a log should be a continuous record of repairs,
parts replacements, gauge and instrument readings
during operational tests, etc.
The manufacturer recommends that a “Customer
Maintenance Inspection Agreement” be established
between the user of this equipment and the install-
ing Authorized Service Dealer. Under this agreement,
(Part No. 053263), an Authorized Service Technician
performs prestart and engine running tests and
checks at six-month and one-year intervals. Ask an
Authorized Service Dealer about this agreement.
The tasks listed in the “Service Schedule” (Section
4.1) cover the minimum recommended maintenance
requirements for this equipment.
Note that many of the tests and checks listed in the
schedule are to be performed only by an Authorized
Service Technician. Fluid capacities and recommen-
dations, as well as other applicable specifications,
are listed in “Specifications” (Section 1.6).
