The engine fuel exhaust gases contain poisonous carbon 

 

„

monoxide. This gas is colorless and odorless, and can 
cause death if inhaled.

The engine of this equipment 

 

„

requires an adequate free 
flow of cooling air. NEVER 
operate this equipment in 
any enclosed or narrow area 
where free flow of the air is 
restricted. If the air flow is 
restricted it will cause injury to people and property and 
serious damage to the equipment or engine.

„

place hands or fingers inside engine 

compartment when engine is running.

„

 operate the engine with heat shields or 

guards removed.

Keep fingers, hands hair and clothing away 

 

„

from all moving parts to prevent injury.

„

remove the radiator cap while the 

engine is hot. High pressure boiling water 
will gush out of the radiator and severely 
scald any persons in the general area of 
the generator.

„

remove the coolant drain plug while the engine 

is hot. Hot coolant will gush out of the coolant tank and 
severely scald any persons in the general area of the 
generator.

„

 remove the engine oil drain plug while the 

engine is hot. Hot oil will gush out of the oil tank and 
severely scald any persons in the general area of the 
generator.

„

 touch the hot exhaust manifold, 

muffler or cylinder. Allow these parts to cool 
before servicing equipment.

„

 run engine without an air filter or with a dirty air 

filter. Severe engine damage may occur. Service air filter
frequently to prevent engine malfunction.

„

 tamper with the factory settings 

of the engine or engine governor. Damage 
to the engine or equipment can result 
if operating in speed ranges above the 
maximum allowable.

Wet stacking is a common problem with diesel engines 

 

„

which are operated for extended periods with light or 
no load applied. When a diesel engine operates without 
sufficient load (less than 40% of the rated output), it will 
not operate at its optimum temperature. This will allow
unburned fuel to accumulate in the exhaust system, 
which can foul the fuel injectors, engine valves and 
exhaust system, including turbochargers, and reduce
the operating performance.

  In order for a diesel engine to operate at peak efficiency, 

it must be able to provide fuel and air in the proper ratio 
and at a high enough engine temperature for the engine 
to completely burn all of the fuel.

  Wet stacking does not usually cause any permanent

damage and can be alleviated if additional load is 
applied to relieve the condition. It can reduce the system 
performance and increase maintenance. Applying an 
increasing load over a period of time until the excess 
fuel is burned off and the system capacity is reached 
usually can repair the condition. This can take several 
hours to burn off the accumulated unburned fuel.

State Health Safety Codes and Public Resources

 

„

Codes specify that in certain locations, spark arresters 
must be used on internal combustion engines that use 
hydrocarbon fuels. A spark arrester is a device designed 
to prevent accidental discharge of sparks or flames
from the engine exhaust. Spark arresters are qualified 
and rated by the United States Forest Service for this 
purpose. In order to comply with local laws regarding 
spark arresters, consult the engine distributor or the 
local Health and Safety Administrator.
