IMPELLER CUTTER EAR RE-SHARPENING-
Rotating blades may be re-sharpened as cutting efficiency decreases. Remove
impeller as described above. Remove attaching hardware for cutting ears.
Using a gloved hand, firmly grasp blade and with an angle grinder, grind a
new edge on interior of blade only. Interior of blade will face center bolt of
impeller. The picture below has the edge to be resurfaced highlighted in black.
DO NOT grind on opposing side of blade as this will reduce or impair any
cutting ability.
Grind ONLY on area highlighted in black
