Operation and Maintenance
Engine operation
Start
Before operating the MWM Acteon engine check:
• Water level.
• Fuel level.
• Lubricant level.
• Soon after to start the engine, heat it up at medium speed, without load. Watch lubricant oil pressure and water
temperature.
• It is recommended to start the engine without accelerating, keeping the engine at idling speed for 30 seconds in
order to pre-lubricate the turbocharger.
• Before stopping the engine, run about 30 seconds at idling speed so that the turbo decrease its speed.
Cold Start
The difficulty of start at very low temperatures can happen due to the collapse of the filter because paraffin formation
or lack of ignition of the fuel.
The following actions can be observed:
• Use winter fuel, which does not form paraffinic flakes at low temperatures, or;
• Case the winter fuel is not available, it is necessary that the filter has a heater on the cylinder head to allow fuel
flow before the start.
Turbocharger Cares
Almost all failures in turbochargers are caused by lubrication deficiency (delay in lubrication,
restriction or lack of oil, intake of impurities in the oil, etc.) or objects or impurities entrance through
intake.
To maximize the turbo lifetime follow these cautions:
• Do not accelerate the engine immediately after the start.
• Wait 30 seconds with the engine at idling speed before stop it.
• Pre-lubricate the turbocharger after oil change or other service that evolves oil drain. Crank the engine a few
times before start the engine. Then run the engine and allow it to run at idling speed for a period of time to
establish a complete circulation and oil pressure before to perform high speeds and load.
• In low temperatures or when the engine is being reactivated after a long period without operation, start the engine
and let it running at idling speed before operating in high speeds.
• Avoid operating the engine at idling speed for long periods of time.
