DRAINING WATER SEPARATING FUEL FILTER
Be careful when draining water separating fuel filter. Diesel fuel is flammable. Be sure ignition key is
OFF. Do not allow fuel to contact any hot surfaces which may cause it to ignite. Do not allow sources
of open flame in the area. Wipe up any spilled fuel immediately. Dispose of fuel soaked rags, paper,
etc. in an appropriate air tight, fire retardant container. Fuel soaked items may spontaneously ignite
and result in a fire hazard which could cause serious bodily injury or death.

The filter (a) can be drained of water and small dirt particles by opening drain cock at bottom of filter. Open
by turning the drain (b) counterclockwise (as viewed from the bottom of the filter). Drain until fuel is clear in ap-
pearance. Close drain by turning clockwise. Tighten securely. Fill fuel filter as previously outlined.

NOTE: To ensure complete draining, in warm weather open the water bleed valve before starting daily opera-
tions. In cold weather, where there is a possibility that the condensed water will freeze, drain the filter shortly after
the end of daily operations.
