Section II. PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS)
a. To ensure that the CBT and the BAP are ready for operation at all times, they must be inspected on a regular
basis so that defects may be found before they result in serious damage, equipment failure, or injury to
personnel. This section contains systematic instructions on inspections, adjustments, and corrections to be
performed by the operator/crew.
While performing preventive maintenance checks and services (PMCS), read and follow all safety instructions
found in the warning summary at the beginning of this manual. Keep in mind all WARNINGs and
CAUTIONs. Failure to observe the WARNINGs and CAUTIONs could result in death or injury to personnel
or damage to equipment.
GENERAL PMCS PROCEDURES.
Drycleaning solvent is TOXIC and flammable. Wear protective goggles and
gloves; use only in a well-ventilated area; avoid contact with skin, eyes, and
clothes; and DO NOT breathe vapors. Keep away from heat or flame. Never
smoke when using drycleaning solvent; the flashpoint for Type II is 140 degrees
F (60 degrees C), and for Type III it is 200 degrees F (93 degrees C). Failure
to follow this warning may result in death or injury to personnel.
If personnel become dizzy while using drycleaning solvent, immediately get
fresh air and medical help. If solvent contacts skin or clothes, flush with cold
water. If solvent contacts eyes, immediately flush them with water and get
immediate medical attention.
When drycleaning solvent is used, notify the local medical authority (preventive
medicine) and environmental coordinator concerning medical surveillance,
respiratory protection, and disposal requirements.
Do not use drycleaning solvent on winch rope (cable). Solvent will soak into
rope strands and rust, causing rope to deteriorate. This may result in the rope
breaking under normal loads and could cause death or injury to personnel.
a. Keep equipment clean. Dirt, grease, oil, and debris may cover up a serious problem. Clean as you work and
as needed. Use drycleaning solvent (Item 13, Appendix E) on all metal surfaces. Use detergent (Item 12,
Appendix E) and water
on rubber, plastic, and painted surfaces.
While performing specific PMCS procedures, inspect the following components:
Bolts, nuts, and screws. Make sure they are not loose, missing, bent, or broken. Report loose or missing
bolts, nuts, and screws to Unit maintenance.
Welds. Inspect for gaps where parts are welded together. Check for loose or chipped paint, rust, and
cracks. Report bad welds to Unit maintenance.
