PREVENTIVE MAINTENANCE
11A-1
SECTION 11A. GENERAL
PREVENTIVE MAINTENANCE
Preventive maintenance (PM) is maintenance per-
formed to prevent malfunctions and component break-
downs by periodically and systemically checking
equipment and systems.
SCHEDULING
The machine should be scheduled for preventive main-
tenance according to the number of hours used, the
severity of the use, and the type of environment the
machine is used in.
Use the manufacturer’s recommendations for preven-
tive maintenance. The recommendations can be
altered as experience is gained with the type of equip-
ment and the environmental conditions.
When performing preventive maintenance tasks, watch
for conditions that appear abnormal. If an abnormal
condition exists a determination must be made to cor-
rect the condition immediately or schedule the tractor
the necessary repairs.
ADMINISTRATION
Record keeping is an important part of preventive
maintenance and also the part most frequently forgot-
ten.
