CHIPPER BLADE REMOVAL AND SHARPENING (TKV ONLY)

Chipper blades are normal replaceable wear items.

DANGER Chipper blade is sharp. Replace any damaged blade.

Depending on the type and amount of wood being chipped, the chipper blade will eventually get dull, losing it’s cutting ability. Evidence of a dull blade is a noticeably reduced chipping ability or a rough cut on end of branch. Note: The chipper blade gap is factory set and should be checked each time impeller is removed from engine crankshaft and reset if required. If reassembly requires a different quantity of shim washers, Billy Goat® shim washer must be used.

1.Follow the steps 1-6 on the impeller removal instructions.

2.Using a 3/16" Allen wrench and 1/2" open end wrench, remove chipper blade from impeller.

3. Sharpen blade by lightly grinding the cutting edge of the blade at 40 degrees (see figure below). It is not necessary to remove all nicks from the cutting edge. CAUTION: Be careful to avoid heat buildup in the blade during sharpening. This will reduce it’s heat- treated hardness properties and will reduce blade life. Evidence of too much heat build-up is a change of color along sharpened edge.

4. The same chipper blade can be sharpened several times. However, blade replacement is required when blade no longer overhangs the chip relief hole in impeller back plate or if increased vibration occurs (see fig below).

5.Chipper blade installation is in reverse order of removal.
