Drycleaning solvent (P-D-680) 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 of flame. Never smoke when using solvent; the flash point for type I
drycleaning solvent is 100°F (38°C) and for type II is 140°F (60°C). Failure to do so may result in
injury or death to personnel.
If personnel become dizzy while using cleaning solvent, immediately get fresh air and medical help.
If solvent contacts skin or clothes, flush with cold water. If solvent contacts eyes, immediately flush
eyes with water and get immediate medical attention.
a. Cleanliness. Dirt, grease, oil, and debris can cover and hide serious problems. Use drycleaning
b. Bolts, Nuts, and Screws. Check bolts, nuts, and screws for obvious looseness, missing, bent, or broken
condition. Look for chipped paint, bare metal, or rust around bolt heads. If any part seems loose, notify unit
c. Welds. Look for loose or chipped paint, rust, or gaps where parts are welded together. If bad welds are found,
notify unit maintenance.
d. Electric Wires and Connectors. Look for cracked or broken insulation, bare wires, and loose or broken
connectors. Tighten loose connectors and make sure wires are in good shape. If bad wires or connectors are found,
notify unit maintenance.
e. Hydraulic Lines and Fittings. Look for wear, damage, leaks, and make sure clamps and fittings are tight. Wet
spots show leaks, and a stain around a connector or fitting can mean a leak. If a loose fitting or connector causes a
leak, tighten it.
f. Damage is defined as: any conditions that affect safety or render the vehicle unusable for mission
g. Rust and Corrosion. Check vehicle body and frame for rust and corrosion. If any bare metal or corrosion
exists, clean, and apply a thin coat of oil. Report it to your supervisor.
The following paragraphs describe the different types/classes of leaks and how they affect the status of the vehicle.
Become familiar with them and remember - WHEN IN DOUBT NOTIFY UNIT MAINTENANCE. Class I and II
leaks are considered minor leaks and operations can continue under these conditions. When operating with these
types of leaks, fluid levels must be checked regularly as required in the PMCS. Class III leaks must be reported to unit
maintenance for corrective action. If there is any doubt about the type of leak, notify unit maintenance.
a. Class / Leaks. Class I leaks are identified by a wetness or discoloration not great enough to form drops. It is
more of a seepage than a leak.
