LEARNING EVENT 1:

DESCRIBE BEFORE-, DURING-,

AND AFTER-OPERATION CHECKS

AND SERVICES ON THE 50-GPM PUMP

To insure that the pump is ready for operation at all times, it must be systematically inspected so

that defects may be discovered and corrected before they result in serious damage or failure. The

necessary preventive maintenance checks and services to be performed are listed in figure 4 on

pages 19 and 20.

The operator will assume responsibility for maintaining the fuel and lubrication levels of the

gasoline engine and inspecting the equipment. Deficiencies must be corrected or reported to

organizational preventive maintenance using DA Form 2404 (figure 5 on page 21).

Equipment Inspection

Engine. Inspect for fuel and oil leaks on and around the engine. Check for bent, cracked,

broken, loose, or missing parts.

Oil Level Gage. Use the oil gage rod and measure the oil level in the crankcase, adding oil if

necessary. Do not overfill. Refer to LO 5-2805-256-12, in Appendix A on page 63, for the

proper grade of oil.

Air Cleaner. Inspect for cleanliness and serviceability. Check the restriction indicator: if RED is

visible, report to organizational preventive maintenance.

Fuel Filter. Inspect the filter for accumulated dirt, water, sediment and leakage.

Spark Plug and Cable. Inspect for insecure installation.

NOTE

Keep the engine free of dirt and oil on all external surfaces. See that the unit

is properly sheltered at all times, and that the cooling shrouds installed are

not damaged.
