DRAINING
Refer to Precautions BEFORE proceeding.
The filter can be drained of water and small dirt particles by opening the water drain cap
(bleed valve).
IMPORTANT: To ensure complete draining, in warm weather, open the drain cock
before starting daily operations. In cold weather, when there is a possibility that the
condensed water will freeze, drain the filter shortly after the end of daily operations.
NOTE: Place a suitable container under fuel filter to catch contaminated fuel and/or water
1. Using a suitable container to catch contaminated fuel and/or water, open drain cap at
bottom of filter by turning the drain counterclockwise (as viewed from the bottom of the
filter).
2. Drain until fuel is clear in appearance.
3. Close drain by turning clockwise.
4. Fill fuel filter as outlined in Filling.
