Avoid Unnecessary Engine Idling
During long engine idling periods, the engine coolant
temperature will fall below the normal operating
range. The incomplete combustion of fuel in a cold
engine will cause crankcase dilution, formation of
lacquer or gummy deposits on the valves, pistons and
rings and rapid accumulation of sludge in the engine.
Drain the cooling system if it is not protected with

Leave the drains open. Open the raw water drains of a
heat exchanger cooling system.

Use only the heavy-duty lubricating oil specified under
Lubricating Oil Specifications.
If the engine does not stop after using the normal
stopping procedure, pull the "Emergency Stop" knob
all the way out. This control cuts off the air to the
engine. Do not try to restart again until the cause for
the malfunction has been found and corrected.
