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.
NOTE: When prolonged engine idling is necessary, maintain at least 800 rpm.
Release the load and decrease the engine speed. Put all shift levers in the neutral position.
Allow the engine to run at half speed or slower with no load for four or five minutes, then move the stop lever to
stop to shut down the engine.
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
CAUTION: The emergency shutdown system should never be used except in an emergency. Use of the
emergency shutdown can cause oil to be sucked past the oil seals and into the blower housing.
The air shut-off valve, located on the blower air inlet housing, must be reset by hand and the "Emergency Stop" knob
pushed in before the engine is ready to start again.
If the unit is equipped with a fuel valve, close it. Fill the fuel tank; a full tank minimizes condensation.
Drain the cooling system if it is not protected with antifreeze and freezing temperatures are expected. Leave the drains
open. Open the raw water drains of a heat exchanger cooling system.
If the engine crankcase was refilled, stop the engine after normal operating temperature has been reached, allow the oil
to drain (approximately 20 minutes) back into the crankcase and check the oil level. Add oil, if necessary, to bring it to
the proper level on the dipstick.
Use only the heavy-duty lubricating oil specified under Lubricating Oil Specifications.
Check and, if necessary, replenish the oil supply in the transmission.
Clean and check the engine thoroughly to make certain it will be ready for the next run.
Refer to Lubrication and Preventive Maintenance and perform all of the daily maintenance operations. Also perform the
operations required for the number of hours or miles the engine has been in operation.
Make the necessary adjustments and minor repairs to correct difficulties which became apparent to the operator during
the last run.
