0087
1. Always perform PMCS in the same order so it gets to be a habit. Once you have had some practice, you will
spot anything wrong in a hurry. If any deficiency is discovered, perform the appropriate troubleshooting task in
Chapter 2 of this manual. If any component or system is not serviceable or if the given service does not correct
the deficiency, notify your supervisor.
2. Before performing preventive maintenance, read all the checks required for the applicable interval and prepare
everything needed to make all the checks. Have several clean rags handy. Perform ALL inspections at the
applicable interval.
WARNING
Solvent cleaning compound MIL-PRF-680 Type III is an environmentally compliant and
low toxicity material. However, it may be irritating to the eyes and skin. Use protective
gloves and goggles. Use in well-ventilated areas. Keep away from open flames and other
sources of ignition. Failure to follow this warning may result in injury or death to personnel.
a. Keep It Clean. Dirt, grease, oil, and debris get in the way and may cover up a serious problem. Clean as
you work and as needed. Use solvent cleaning compound on all metal surfaces. Use general purpose
liquid detergent and water when you clean rubber, plastic, and painted surfaces.
