PREVENTIVE MAINTENANCE
Preventive Maintenance (PM) is maintenance per-
formed to prevent malfunctions and parts breakdowns
by periodically and systematically checking equipment
and its systems.
Preventive Maintenance will cut back corrective main-
tenance.
SCHEDULING
Each machine should be scheduled for preventive
maintenance according to the hours used, its severity
of use, and the type of environment the machine is
used in.
Use the manufacturer’s recommendation of preventive
maintenance. These recommendations can then be
altered as experience is gained with the type of equip-
ment and the type of environment in which it operates.
While performing preventive maintenance tasks the
individual should always be alert to conditions that may
seem abnormal. If an abnormal condition is detected a
determination must be made to either correct the condi-
tion immediately or schedule the tractor in the shop for
necessary repairs.
ADMINISTRATION
Record keeping is an important and most often a for-
gotten part of preventive maintenance.
Jacobsen has developed a PMMRS (Preventive Main-
tenance Management Record System).
PMMRS PROGRAM KITS
The PMMRS kits and replacement forms (see Figure
11A-1) are available directly from your local Jacobsen
