Important
The right side of the reel cutter (when you
face the mower unit from the front) is inclined
to wear earlier than the left side. Accordingly
be sure to move the brush from the left to the
right to apply the abrasive.

Back Lapping of Reel Cutter (Cutting Cylinder)_006
Apply the abrasive evenly with the brush on
the top side of reel cutter (cutting cylinder)
where the newspaper was cut well or of
chalk-marked locations.
(Never apply to blunt areas.)
Rotate the reel cutter for a while and stop its
rotation when the sound of contact is lost.
Turn off the lapping machine.
Or stop rotating the lapping handle.
Disconnect the lapping machine or the
lapping handle (accessory tool).
Wash off or wipe off with a cloth, etc., the
abrasive from the reel cutter (cutting
cylinder), and then check it for sharpness.
Repeat steps 4 to 13 until the entire range
(three or four points from the left edge to the
right one) of the reel cutter (cutting cylinder)
is uniformly sharpened.
Finally, apply abrasive to the entire blade
width of the reel cutter (cutting cylinder) and
perform final back lapping.
Important
Pay attention not to pour water over the
engine and electric components when
cleaning.
Wash out the abrasive with a washer etc.
While checking the blade for sharpness,
adjust blade engagement.
