Leakage Definition
When operating with Class I or II leak, continue to check fluid levels as required in your PMCS.
Class III leaks should be reported immediately to your supervisor or unit maintenance.
CAUTION
Equipment should not be operated with a class III leak. Damage to equipment may result.
It is necessary to know how fluid leakage affects the status of the LWP. The following are definitions of the
classes of leakage an operator or crewmember needs to know to be able to determine the condition of the leak.
Learn and then be familiar with them, and remember, when in doubt, ask your supervisor.
Leakage Definitions for Crew/Operator PMCS are as follows:
CLASS I Seepage of fluid (as indicated by wetness or discoloration) not great enough to form drops.
CLASS II Leakage of fluid great enough to form drops but not enough to cause drops to drip from item
being checked.
CLASS III Leakage of fluid great enough to form drops which falls from the item being checked.
INSPECTION
Look for signs of a problem or trouble. Senses help here. You can feel, smell, hear, or see many
problems. Be alert when around the LWP.
Safety inspections shall be done daily to prevent any accidental injuries and/or equipment damage.
Inspect to see if items are in good condition. Are they correctly assembled, stowed, secured, excessively worn,
leaking, corroded, or properly lubricated? Correct any problems found or notify unit maintenance.
There are some common items to check all over the LWP. These include the following:
Bolts, clamps, nuts, and screws; continually check for looseness. Look for chipped paint, bare metal,
rust, or corrosion around bolt and screw heads and nuts. Tighten the bolts, nuts, and screws when you
find them loose. If tools are not available, notify unit maintenance.
Welds; many items on the LWP are welded. To check these welds, look for chipped paint, rust,
corrosion, or gaps. When these conditions exist, notify unit maintenance on DA Form 2404.
Electrical cables/wires, connectors, and harnesses; tighten loose connections. Look for cracked or
broken insulation, bare wires, and broken connectors. If any are found, notify unit maintenance.
Hoses and fluid lines; look for wear, damage, and leaks. Make sure clamps and fittings are tight. Wet
spots mean a leak. A stain by a fitting or connector can also mean a leak. When you find a leak, notify
unit maintenance.
LUBRICATION SERVICE INTERVALS NORMAL CONDITIONS
For safer, more trouble free operations, make sure that the LWP is serviced when it needs it. For the proper
lubrication and service intervals, see the appropriate lubrication order.
LUBRICATION SERVICE INTERVALS UNUSUAL CONDITIONS
The LWP will require extra service and care when you operate under unusual conditions. High or low
temperatures, long periods of hard use, or continued use in sand, water, mud, or snow will break down the
lubricant, requiring you to add or change lubricant more often.
