Check oil level.
For this purpose, follow these steps:-
a) Draw dipstick and clean with lint free cloth.
b) Return dipstick, wait a little untill the oil has watted the dipstick.
c) Then remove the dipstick again and check oil level.

B) Air in fuel system.
Bleed air from fuel system in the following steps:-
a) Loosen the bleed plug on the fuel filter and operate the priming pump until the fuel emerges of bubbles. Tighten the bleed plug.
b) Then loosen banjo plug on injection pump and operate priming pump until fuel emerges free of bubbles. Tighten the banjo plug.
C) Valve clearance is not proper.
To check Valve clearance, follow these steps:-
a) Un-screw bolts and remove cylinder cover.
b) Crank engine until the inlet valve closed. Then turn approx (1/2) half turn further.
c) The feeler gauge should pass between the valve cone end and the rocker lever with suction
d) If the valve clearance need resetting, Loosen the lock nut and readjust by means of the set screw.
e) Tighten lock nut and recheck valve clearances.
f) Renew gasket, sealing ring and fit cylinder head cover.
D) Deffective injector.
Remove defective injector and get it overhauled/calibrated or alternatively replace it with new one.
