Commissioning and Operation

5.1

Your engine needs preparations before starting

At the time of initial commissioning of a new or overhauled engine and before daily starting of the engine,
• Check the fuel, coolant and oil level, replenish if necessary.
The notches in the dipstick indicate the highest and lowest permissible oil levels.
The technical specifications for fuel, oil and coolant are specified in the "Technical Information" section.
• Check electrical connection and battery terminals
• Look for leakages around the engine - fuel, oil.
• Check condition of belts
• Check Cleanliness
Ensure utmost cleanliness when handling fuels, lubricants and coolants.
• Perform specified daily maintenance.

Running-in

5.2.1

Operation of a new engine (break-in)

All engines require some operational period for sliding surfaces like pistons, rings and liners to take seat.
During this period, the surfaces are taking shape and are conforming to each other. There is a possibility
of oil film breakage under high load or under high speed due to high spots. Therefore the following precautions
need to be observed for every engine.
Precautions during first 150 hours of operation
• Engine should be run at rated rpm with 25% load until the temperature of the engine comes to normal
operating condition.
• Overload, continuous full load operation and continuous no load operation should be avoided.
• Abrupt start and stop of the engine should be avoided.
• Engine load should not exceed 70% of its prime rating.
• Maintenance and inspection must be accomplished thoroughly.
• Carry out 50 hour maintenance and replacement thoroughly.
5.2.2 Check points for running-in
During the running-in (the initial running of the engine) period,
• Check engine oil level frequently. Maintain oil level in the safe range, between the "min." and "max."
marks on dipstick.
Note:
If you have a problem getting a good oil level reading on dipstick, rotate dipstick 180° and reinsert for
check.
• If engine trips because of Low Lub Oil pressure (this will be indicated by a lamp), check oil level on
dipstick. If required, add oil to the oil pan. Do not overfill. If level is correct then reset the fault by key
switch on safety unit. If the status still exists, see your DEALER for possible switch or oil pump &
line malfunction.
