LEAKAGE DEFINITIONS FOR OPERATOR PMCS

TM 55-1915-200-10

USE CAUTION when using cleaning solvents. Cleaning solvents

evaporate quickly and can irritate exposed skin if solvents contact skin.

In cold weather, contact of exposed skin with cleaning solvents can

CAUTION

When cleaning engine compartment areas, engine must

be COLD (same temperature as ambient air). DO NOT

point water or steam directly at any electrical connection.

DO NOT use high-pressure water supply system.

Damage to engine, electrical system and other components

may result.

NOTE

Only use those authorized cleaning solvents or agents

listed in Appendix D.

a. Cleaning Engine Compartment Areas.

(1) When using water to clean the engine compartment, always cover alternators and air

cleaner inlet using waterproof material. Use water pressure and volume similar to a standard household

type water supply system (45-70 psi, 6.5-10.2 kPa).

(2) After cleaning, allow engine to air dry. Do not use compressed air to dry engine. Do not

run engine to decrease drying time.

(3) Remove all component covers before starting engine.

b. Treating Mildewed Areas. Scrubbing with a dry brush can clean mildewed canvas. If it is

necessary to use water to remove dirt, it should not be used until mildew has been removed. After

removing mildew, examine fabric. Look for evidence of deterioration. If canvas has deteriorated, it

should be replaced.

CAUTION

Keep cleaning solvents, gasoline and lubricants away from rubber

or soft plastic parts since they will cause material to deteriorate.

c. Cleaning Rust or Grease. When cleaning grease buildup or rusty spots, use a cleaning

solvent. Apply a thin coat of oil to the affected area.

2-2.4. LEAKAGE DEFINITIONS FOR OPERATOR PMCS. It is necessary to know how fluid leakage

affects the status of the LSV. Following are types/classes of leakage an operator needs to know to be

able to determine the status of the LSV. Learn these leakage definitions and remember when in

doubt, notify the supervisor.

CAUTION

Equipment operation is allowable with minor leakages (Class I or II). Of course,

consideration must be given to fluid capacity in the item/system being checked/

inspected. When in doubt, notify the supervisor.

When operating with Class I or II leaks, continue to check fluid levels as required

in the PMCS.

Class III leaks should be reported immediately to the supervisor.
