(2) Emergency Conditions

To prevent personal damage or damage to generator set, use of the EMERGENCY SHUT
DOWN (E-STOP) push button switch will provide immediate shut down of the engine. Once
pushed in, the E-STOP button must be pulled back out to restart the generator set.

Depress E-STOP button; engine will shut down
·
Pull E-STOP button back out to restart.
g. Adverse Weather Precautions

(1) Cold weather operation

Operation of this engine-driven unit at sub-zero temperatures requires special precautions and
extra servicing from both operation and maintenance personnel, if poor performance or total
functional failure is to be avoided. Consult the Engine Manufactures Maintenance and Operator's
Manual and recommendations below.
a. Fuel system
Keep system clean and free from water which may collect in a low spot in the fuel line and
freeze, plugging the line. Fuel tanks should be kept FULL to prevent water condensation from
the air above the fuel.
b. Fuel Storage
Keep fuel storage tanks or drums as full as possible to avoid condensation of moisture from
the air above the fuel. After filling or moving fuel containers, allow fuel to settle before using.
Never draw fuel from the extreme bottom of the container. Strain all fuel to remove any
foreign matter. When operating outdoors, take steps to prevent the entry of snow, water, and
ice into the fuel containers.
c. Cooling system
Prior to cold weather, drain and flush the cooling system to remove accumulations of rust and
sediment. Mix and add antifreeze solution, check the cooling system connections for leaks.
Add a can of rust inhibitor to the radiator when system is winterized. This will keep system
cleaner and furnish lubrication for the water pump.
d. Lubrication
Drain the crankcase (preferably when warm after running) and fill with a lighter grade of oil.
See Engine Oil Recommendations chart in the Engine Manufactures User's Manual for
recommended viscosity for various atmospheric temperatures. In cold weather, drain oil more
frequently. Water condenses and collects quickly, mixes with the oil and increases deposits
to form a sludge. Check oil frequently for this condition. Water in crankcase may freeze and
cause serious damage to the oil pump, or shut off the oil supply.
e. Electrical system
In cold weather, the most efficient electrical system is needed to start the cold engine. Check
the entire system for loose connections or indication of bad wiring or shorted conditions.
f. Battery
Battery efficiency decreases sharply with lower temperatures. Make sure of full charge before
attempting to start engine in sub-zero conditions.
