Operation of the 50-GPM Pump
The operation of the pump, once started, is largely automatic. The operator should be constantly
on watch for problems when the pump is in operation.
Some problems for which the operator should keep watch are overheating, failure to pump at
capacity, vibration, and leaks. Note all defects discovered during operation for future correction,
to be made as soon as operation has ceased. Stop operation immediately if a deficiency is noted
during operation that would damage the equipment if operation was continued.
Stopping the Pump
The procedures for stopping either model of the gasoline engine which may be on the 50-GPM
Pump vary slightly.
To stop the MS 1A08-3 model engine, perform the following:
Remove the entire end item load from the engine if applicable.
Move the throttle control to the idle position and allow the engine to cool for
approximately two minutes.
Turn the ignition switch off.
Close the fuel shut-off valve.
Perform the after-operation checks and services listed in figure 4 on page 19.
