Fuel FilterThe fuel filter removes contaminants from the fuel as itenters the engine for combustion. Over time the filtercan become plugged and cause the engine to losepower, run roughly or fail to start. The fuel filter shouldbe changed every 500 hours or more often if neededto prevent these conditions from occurring.To change the fuel filter:1. Clean the outside of the filter housing (A) thor-oughly to reduce the chances of contaminantsbeing introduced into the fuel system.2. Twist the housing counter clockwise (when viewedfrom the bottom) and remove it from the fuel pump(B).3. Then remove the filter element (C) from the hous-ing by holding the housing firmly in one hand andpushing down on the filter element while turning itcounter clockwise within the housing. Turn approx-imately 90º and then remove the filter from thehousing. (fig. 11-30)4. Once removal is complete, insert a new filter ele-ment into the housing. Press down on the elementand turn it clockwise approximately 90º to seat it.5. Reinstall the filter/housing assembly onto the filterhead by threading it onto the head until the hous-ing shoulder contacts the head. Then turn ¼ turn(90º) past this point to seat the housing.Case Drain FilterThe PT-100 Forestry is also equipped with a filter inthe auxiliary circuit case drain line.
