Restriction indicator
The restriction indicator for these engines must work at a pressure difference of 381/457 mm (15/18 in) of water
gauge. It is fitted on the air filter outlet or between the air filter and the induction manifold.
When the red warning indicator (A1) is seen through the clear panel (A2) after the engine has stopped, the air
filter element must be removed for service.
After a clean element has been fitted, press the rubber bottom (A3) or the button (A4) of the restriction indicator
to reset the red warning indicator.
