Fuel prefilter – Checking differential pressure with single-stage filter
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 point-
er (3) is ≥ 0.3 bar, flush filter element of the cut-in filter (→ Page 179).
Setting differential pressure
gauge with switchable duplex
filter
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.
