PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS) INTRODUCTION
INTRODUCTION
PMCS are performed to keep the Backhoe Loader (BHL) in operating condition. Inspect the BHL within
specified intervals so defects are found and corrected or problems are reported before any serious damage
or failure occurs. Do the PMCS as shown in the PMCS table (WP 0022). Pay attention to WARNINGs,
CAUTIONs, and NOTEs. A WARNING means someone could be hurt. A CAUTION means equipment could
be damaged. A NOTE is used to highlight essential procedures, conditions, or statements, or convey
important instructional data to the user.
NOTE
Designated intervals are performed under usual operating conditions. PMCS intervals must
be performed more frequently when operating under unusual conditions.
1. Always perform preventive maintenance in the same order so it gets to be a habit.
2. Tools included with the BHL are to be used when doing the PMCS. Wiping rags (WP 0029, Item 28) are
needed to remove dirt or grease.
3. If you find something wrong when performing the PMCS, fix it if you can, using troubleshooting
procedures (WP 0019) and/or maintenance procedures.
4. If something appears to be wrong and you cannot repair it, write it down on your DA Form 5988-E. If you
find something seriously wrong, report it to field level maintenance as soon as possible.
5. Item numbers in column 1 of the PMCS table indicate the PMCS sequence. Use these item numbers for
the TM number column on DA Form 5988-E.
6. Information in column 5 of the PMCS table lists conditions that make the equipment not ready/available.
Write up items not repaired on DA Form 5988-E for field level maintenance. For further information on
how to use these forms, see DA PAM 738-750.
CORROSION PREVENTION AND CONTROL (CPC)
CPC of Army materiel is a continuing concern. It is important that any corrosion problems with this item be
reported so that the problem can be corrected and improvements can be made to prevent the problem in
future systems. While corrosion is typically associated with rusting of metals, it can also include deterioration
of other materials, such as rubber and plastic. Unusual cracking, softening, swelling, or breaking of these
materials may be a corrosion problem. If a corrosion problem is identified, it can be reported using SF 368,
Product Quality Deficiency Report. Use of key words such as corrosion, rust, deterioration, or cracking will
ensure that the information is identified as a CPC problem. The form should be submitted to the address
specified in DA PAM 738-750.
