Caution
Be careful when lapping the reel because contact
with the reel or other moving parts can result in
personal injury.
7. To make an adjustment to the cutting units while
backlapping, disengage reels and turn engine OFF.
After adjustments have been completed, repeat steps
4–6.
8. When backlap operation is completed, stop the engine,
rotate backlap knob to MOW position, set reel speed
controls to desired mowing setting and wash all lapping
compound off cutting units.
Note: Additional instructions and procedures on
Backlapping are available in the TORO Sharpening Reel &
Rotary Mowers Manual Form No. 80–300SL.
Note: For a better cutting edge, run a file across the front
face of the bedknife when the lapping operation is
completed. This will remove any burrs or rough edges that
may have built up on the cutting edge.
