Setting adjustable pointer of differential pressure

gauge

1. After installation of a new filter element, align

adjustable pointer (2) with pressure-indicating

pointer (3) of p ressure gauge (1).

2. Verify that differential pressure is within the limit.

Fuel prefilter – checking differential p ressure

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 6 – 30).
