To drain water from coarse fuel filter
When the information about the triggering of wa-
ter sensor is displayed, you need to drain sediment from
the coarse fuel filter: remove the water drain plug from
the filter cap and drain sediment until clean fuel appears.
Prior to draining the water-fuel mixture from wa-
ter collection vessel or prior to air release with the help
of priming pump, place the vessel to collect water-fuel
mixture under the coarse fuel filter.
Avoid fuel getting onto vehicle aggregates and
soil.
