Water Drain Valve Operation
The fuel filter can be drained of water and small dirt particles without removal of filter.
NOTE: To ensure complete draining, in warm weather open the water bleed valve before
starting daily operations. In cold weather, where there is a possibility that the condensed
water will freeze, drain the filter shortly after the end of daily operations.
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.
