LAUNDRY ADVANCED SYSTEM
PREVENTIVE MAINTENANCE CHECKS AND SERVICES -- Continued
Equipment operation is allowable with minor leakages (Class I or II) except for fuel or thermal fluid leaks. Of
course, consideration must be given to the fluid capacity of the item or system being checked. When in
doubt, ask your supervisor.
When operating with class I or II fluid leaks, continue to check fluid levels as required in your PMCS.
Class III leaks should be reported immediately to your supervisor.
It is necessary to know how fluid leakage affects the status of the LADS. The following are definitions of the classes
of leakage an maintainer 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 Operator PMCS.
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
CLASS III -- Leakage of fluid great enough to form drops that fall from the item being checked.
Look for signs of a problem or trouble. Senses can help here. You can feel, smell, hear, or see many problems. Be
alert when inspecting LADS.
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.
There are some common items to check all over the LADS. These include the following:
1. Bolts, clamps, nuts, and screws: Continuously check for looseness. Look for chipped paint, bare metal, rust, or
corrosion around bolt and screw heads and nuts. Tighten them when you find them loose.
2. Welds: Many items on the LADS are welded. To check these welds look for chipped paint, rust, corrosion, or gaps.
When these conditions exist, repair as necessary.
3. Electrical wires, connectors, and harnesses: Tighten loose connectors. Look for cracked or broken insulation, bare
wires and broken connectors. If any are found, repair as necessary.
4. Hoses and fluid lines: Look for wear, damage and leaks, and make sure clamps and fittings are tight. Wet spots
mean a leak. A stain by a fitting or connector can also mean a leak. Correct any problems found.
LUBRICATION SERVICE INTERVALS
For safer, more trouble free operations, make sure that your LADS is serviced when it needs it.
Your LADS 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 the lubricant more often.
