3.4.2. Operation of a new engine ( Break-In )
Because the sliding surfaces of a new engine are not lapped enough, the oil film can
be destroyed easily by overload or overspeed and the engine life-time may be
shortened.
Therefore the following things must be obeyed by all means.
Up to the first 1,000km(50 hours)
▲
Engine should be run at fast idling until the temperature of the engine becomes
normal operating condition.
▲
Overload or continuous high speed operation should be avoided.
▲
High speed operation with no load should be prevented.
▲
Abrupt start and stop of the engine should be avoided.
▲
Engine speed must be under 70% of its maximum speed.
▲
Maintenance and inspection must be accomplished thoroughly.
3.4.3. Check points for break-in
During the break-in (the initial running of the engine) period, be particularly observant
as follows:
a) Check engine oil level frequently. Maintain oil level in the safe range, between the
" min. " and “ max. " marks on dipstick.
