PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS) INTRODUCTION
To ensure that the 966H Wheel Loader is ready for operation at all times, it must be inspected on a regular basis so that
defects may be found and corrected before they result in injury, damage, or equipment failure.
The PMCS Table in WP 0012 00 contains systematic instructions on inspections, lubrications, services, tests, and cor-
rections to be performed by the operator to keep your equipment in good operating condition and ready for its primary

The WARNINGs and CAUTIONs appearing in your PMCS table should always be observed. WARNINGs
and CAUTIONs appear before applicable procedures. You must observe these WARNINGs to prevent
injury or death to yourself and others, and CAUTIONs to prevent your equipment from being damaged.
Procedure Column. This column gives the procedure you must perform to check or service the item listed in the Item
to Check/Service column, to know if the equipment is ready or available for its intended mission. You must perform the
procedure at the time stated in the Interval column.
Not Fully Mission Capable If: Column. Information in this column tells you what faults will keep your equipment
from being capable of performing its primary mission. If you perform check/service procedures that show faults listed in
this column, the equipment is not mission-capable. Follow standard operating procedures for maintaining the equipment
or reporting equipment failure.
GENERAL PMCS PROCEDURES
Always perform PMCS in the same order so it gets to be a habit. Once you have had some practice, you will spot any-
thing wrong in a hurry. If the machine does not perform as required, refer to the appropriate troubleshooting procedure
If anything looks wrong and you cannot fix it, write it on your DA Form 2404 or DA Form 5988-E. If you find some-
thing seriously wrong, IMMEDIATELY report it to your supervisor.
Before performing preventive maintenance, read all the checks required for the applicable interval and prepare all that is
needed to make all the checks. You will always need a rag (Item 13, WP 0027 00) or two.
