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.
When prolonged engine idling is necessary, maintain at least 800 rpm.
1. Release the load and decrease the engine speed. Put all shift levers in the neutral position.
2. Allow the engine to run at half speed or slower with no load for a short time, 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 and corrected.
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 shutoff 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.
