2.43 PREVENTIVE MAINTENANCE AND
INSPECTION SCHEDULE.
The preventive maintenance and inspection checks are
listed and defined in the following table. This table is
divided into two basic parts, the “AREA” to be inspected,
and the “INTERVAL” at which the inspection is to take
place. Under the “AREA’ portion of the table, the various
systems along with the components that make up that
system are listed. The INTERVAL portion of the table is
divided into five columns representing the various inspec-
tion time periods. The numbers listed within the interval
column represent the applicable inspection code for
which that component is to be checked.
The checks and services listed in this schedule are not
intended to replace any local or regional regulations that
may pertain to this type of equipment, nor should the lists
be considered as all inclusive. Variances in interval times
may occur due to climate and/or conditions and depend-
ing on the location and use of the machine.
JLG Industries requires that a complete annual inspection
be performed in accordance with the “Annual Machine
Inspection Report” form. Forms are supplied with each
