Engine Protective Devices -
Check
Alarms and shutoffs must function properly. Alarms
provide timely warning to the operator. Shutoffs help
to prevent damage to the engine. It is impossible to
determine if the engine protective devices are in
good working order during normal operation.
Malfunctions must be simulated in order to test the
engine protective devices.
A calibration check of the engine protective devices
will ensure that the alarms and shutoffs activate at
the setpoints. Ensure that the engine protective
devices are functioning properly.
NOTICE
During testing, abnormal operating conditions must
be simulated.
The tests must be performed correctly in order to pre-
vent possible damage to the engine.
To prevent damage to the engine, only authorized
service personnel or your Perkins dealer should
perform the tests.
Visual Inspection
Visually check the condition of all gauges, sensors
and wiring. Look for wiring and components that are
loose, broken, or damaged. Damaged wiring or
components should be repaired or replaced
immediately.

NOTICE
Only qualified service personel should perform this
maintenance. Refer to the Service Manual or your au-
thorized Perkins dealer or your Perkins distributor for
the complete valve lash adjustment procedure.
Operation of Perkins engines with incorrect valve
lash can reduce engine efficiency, and also reduce
engine component life.
Ensure that the engine can not be started while
this maintenance is being performed. To help pre-
vent possible injury, do not use the starting motor
to turn the flywheel.
Hot engine components can cause burns. Allow
additional time for the engine to cool before
measuring/adjusting valve lash clearance.
Note: The valve bridges must be equalized before
the valve lash is adjusted.
Refer to Systems Operation, Testing and Adjusting,
“Valve Lash - Adjust” for the correct procedure.
