Certain E110B, E120B, E200B, EL200B, E240B, EL240B, E240C, EL240C, 320, 320 L, 325, and 325 L Excavators; 446 Backhoe Loaders; CS563 and CP563 Compactors; IT12B and IT14B Toolcarriers; 910E and 950F Loaders; and 3114 and 3116 Engines may experience hard starting when the engine is warm. This problem may result from internal wear on the scroll-edge of the fuel injector plunger. The wear is caused by very fine dirt in the fuel going through the filter when it becomes plugged, and by the practice of pre-filling the fuel filter with contaminated fuel before installing it.
