How to stop the engine
According to the equipment fitted, either turn the engine start key to the “O” position (A/B) or operate the
manual stop control. If a manual stop control is used, ensure that the control returns to the “run” position after
the engine has stopped. Also ensure that the engine start key is turned to the “O” position.
Caution: It is recommended that a turbocharged engine is run at approximately 1000 rev/min at a reduced
load for 2-3 minutes before it is shut down. This will allow the turbocharger to cool.
Adjustment of engine speed range
The idle or maximum speed settings must not be changed by the engine operator because this can damage
the engine or transmission. 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 or POWER EXCHANGE engine is not necessary. Prolonged operation
at light loads during the early life of the engine is not recommended.
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 °C (140 °F).
The engine will benefit if the load is applied as soon as possible after the engine is put into service.
Cautions:
z Do not operate the engine at high speeds without a load.
z Do not overload the engine.
