Adjustment of the engine speed range
The idle or the maximum speed settings must not
be changed by the engine operator, because this
can damage the engine or generator. The warranty
of the engine can be affected if the seals on the fuel
injection pump are broken during the warranty period
by a person who is not approved by Perkins.
Running-in
A gradual running-in of a new engine is not
necessary. Prolonged operation at light loads during
the early life of the engine can cause lubricating oil
to enter the exhaust system. Maximum load can
be applied to a new engine as soon as the engine
is put into service and the coolant temperature has
reached a minimum of 60
O
C (140
O
F).
The engine will benet if the load is applied as soon
as possible after the engine is put into service.
Cautions:
• Do not operate the engine at high speeds without
a load.
• Do not overload the engine.
