DCA-125USJ — SAFETY INFORMATION

ENGINE SAFETY

DANGER

„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.

WARNING

„DO NOT place hands or fingers inside engine compartment when engine is running.

„NEVER operate the engine with heat shields or guards removed.

„ Keep fingers, hands hair and clothing away from all moving parts to prevent injury.

„ DO NOT 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.

„DO NOT 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.

„DO NOT 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.

CAUTION

„NEVER touch the hot exhaust manifold, muffler or cylinder. Allow these parts to cool

before servicing equipment.

NOTICE

„NEVER 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.

„NEVER 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.
