REPLACEMENT (REMOVAL) OF BLADE SET
Your trimmer has a preset tension assembly on the blade set. To
remove blade set from your trimmer, remove from charger base.
Turn the trimmer upside down so teeth of blades are facing down.
You may wish to set the trimmer on a flat surface while
performing these operations. Using a phillips type screwdriver,
unscrew the two blade screws (Figure F). Remove blade set from
trimmer. Install new blade set, making sure the blade yoke cradles
the armature pin on trimmer (Figure G). There is no need to adjust
blade tension before use, as tension has been preset at the factory.
Align screw holes of blade set to screw inserts on trimmer
housing. Replace the screws. Before tightening down blade
screws, check alignment of blade set to housing, making sure that
they are parallel. Tighten down screws.
