ORGANIZATIONAL PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS)
To ensure the crane is ready for operation at all times, inspect it systematically so that any defects can be
discovered and corrected before they result in serious damage or failure. The table on the next few pages
contains the organizational level PMCS.
Record all deficiencies and shortcomings, along with the corrective action taken on a DA Form 2404. The Item
Number column of the table is the source for the numbers used in the TM Number column on DA Form 2404.
Dry cleaning solvent PD-680 is toxic and
flammable. Wear protective goggles and gloves
and use only in a well ventilated area. Avoid
contact with skin, eyes, and clothes and don't
breather vapors. Do not use near open flame or
excessive heat. The flash point is 100 to 138F
(38 to 59C). If you become dizzy while using
solvent, get fresh air immediately and get
medical aid. If contact with eyes is made, wash
your eyes with water and get medical aid
Compressed air, used for cleaning purposes will
not exceed 30 psi. Use only with effective chip
guarding and personnel protective equipment
(goggles/ shield/ loves, etc.).
Keep it clean: dirt, grease, oil, and debris only get in the way and may cover up a serious problem. Clean as you
work and as needed. Use dry cleaning solvent (PD-680) to clean metal surfaces. Use soap and water when you
clean rubber or plastic material.
Bolts, nuts, and screws: Check that they are not loose, missing, bent, or broken. You can't try them all with a
tool, of course, but look for chipped paint, bare metal or rust around bolt heads. Tighten any bolt, nut, or screw
that you find loose.
Welds: Look for loose or chipped paint, rust or gaps where parts are welded together. If you find a bad weld,
report it to direct support maintenance.
Electric wires and connectors: Look for cracked or broken insulation, bare wires and loose or broken connectors.
Tighten loose connections and make sure the wires are in good condition.
Hoses and fluid lines: Look for wear, damage, and leaks. Make sure clamps and fittings are tight. Wet spots
show leaks, but a stain around a fitting or connector can also mean a leak. If leakage comes from a loose fitting
or connector, tighten the fitting or connector. If something is broken or worn out, either correct it or report it to
direct support maintenance (refer to the Maintenance Allocation Chart).
If something doesn't work, troubleshoot it according to the instructions in this manual.
If anything looks wrong and you can't fix it, write it down on your DA Form 2404.
