Check the sharpness of the entire range
(three or four points from the left edge to the
right one) of the reel cutter (cutting cylinder).
Using a piece of chalk, mark locations on the
blade that are sharp.
Set the reel reverse lever for the mower units
to the "Reverse" position, and then set the
transmission selector lever to the "LAP"
position.
Shift the lever(s) to the "N" position for the
mower unit(s) for which you will not perform
back lapping.
Start the engine, and run it at a low rpm.
Set the reel rotation switch to the "MOW"
(reel rotation) to reverse the reel cutter
(cutting cylinder).
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.)
Idle the machine for a while and, when
contact noise is no longer heard, return the
reel rotation switch to the "TRAVEL" (reel
stop) position to stop the reel cutter (cutting
cylinder).
Stop the engine.
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 2 to 11 until the entire range
(three or four points from the left edge to the
right one) of the reel cutter (cutting cylinder)
will be uniformly sharpened.
Finally, apply abrasive to the entire blade
width of the reel cutter (cutting cylinder) and
perform final back lapping.
Stop the rotation of the reel cutter (cutting
cylinder), stop the engine, and then wash off
the abrasive using a washer etc.
While checking the blade for sharpness,
adjust blade engagement.

Adjusting CAM
When the gap at the left frame side between
the reel cutter (cutting cylinder) and the bed
knife (bottom blade) appears.
Loosen the locknut and turn the left cam
bush clockwise for the gap size.
When you raise the bed knife (bottom blade)
for 0.1mm (0.039 inch), turn the left cam
bush clockwise for 30 degrees.
Once the adjustment completed, tighten the
locknut securely.
When the gap at the right frame side between
the reel cutter (cutting cylinder) and the bed
knife (bottom blade) appears.
Loosen the locknut and turn the right cam
bush anticlockwise for the gap size.
Once the adjustment completed, tighten the
locknut securely.
Note:
The figure below shows the situation when you
see from the left frame.
The right frame is mirror reversed.
