Differential pressure gauge ad-
justment
1.
When installing the new filter element: align
adjustable pointer (2) with pressure-indicat-
ing pointer (3) of pressure gauge (1).
2.
Verify that differential pressure is within the
limit.
Fuel prefilter – Differential pressure check
1.
With the engine running at full load or rated power, read off pressure at gauge (1).
2.
If differential pressure as indicated between position of adjustable pointer (2) and pressure-indicating pointer
(3) of pressure gauge is ≥ 0.3 bar, flush filter element of the cut-in filter (→ Page 179).
