SERVICE MANUAL NUMBER 22

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.
3. Close the drain. Tighten securely.
4. Fill the fuel filter.
