► Ensure sufcient fuel level in the fuel tank.
► Drain out water and impurities from fuel water separator and lter
respectively

Table 4.1
Record basic engine parameter during early life of the engine.
Monitor it every routine inspection and maintenance. Gradual
drop in oil pressure is the indicator of progressive wear in
inter-nal parts. If any abnormal change in parameter is noticed,
shutdown the engine immediately. Find out and rectify the
cause of trouble before restart. Refer table 4.2 for specied t
and clear- ance values
