8) Precaution as to inspection
Caution
•Place the machine on the level ground for inspection and repair.
Check that all parts are at rest.
•Clogging of the cooling air intake of the engine, air intake of the air
cleaner, muffler, and exhaust pipe with mown grass or other foreign
substances may cause fire due to engine malfunction or overheating.
Stop the work immediately, and remove the clogging substance after the

The minimum mowing height is the height on the average condition green. In the case
that the undulation of green is substantial, set the mowing height higher lest the lawn be
shaved.
2) Adjust the front groomer according to the condition of the green before use.
*If the groomer blades are set deeper than the ground surface, the shaft may bend.
*The front groomer, when it is put too low, will apply an excessive load to the engine and
transmission section, causing malfunction or failure.
3) When using the grooming brush, adjust the height so that it will be equal to the mowing
height.
The brush will be worn easily when the height is too low.
4) [IMPORTANT] Adjustment of front roller height
Bring the mowing height gauge into contact with the front and rear rollers (as shown
below), and adjust the height of the bottom blade.
a. Loosen the long nut (1-39) of the roller bracket, and move the front roller up or down with
roller adjuster (1-24).
b. Position the front roller with the mowing height gauge.
c. Make adjustment at right and left ends of the mowing unit.

6. Blade engagement
Check that the engine is at rest before making adjustment.
Grind and adjust the blade reel cylinder and bottom blade entirely so that a newspaper will
be cut sharply.
Conduct lapping after mowing operation (before adjusting the engagement).
1) Check the engine portion of the blade reel cylinder to check which portion is dull. (If a
newspaper can not be cut in any portion, put in two sheets of paper to carefully check
which portion is dull).
2) Connect the lapping machine (RM20A) or lapping bolt (option) to the lapping shaft of the
mower.
3) Rotate the blade reel cylinder in the direction opposite to the mowing direction, and
apply abrasive with a brush only to the portion where a newspaper was sharply cut.
The portion where a newspaper was not cut is worn away. Do not apply abrasive to
such portions.
The right side (when viewed from the front of the blade reel cylinder) of the blade reel
cylinder will be worn away 3-4 times earlier than the left side. When applying abrasive to
the blade reel cylinder, be sure to move the brush from left to right. When the abrasive is
a mixture of powder (#200~#400) and oil, mix them at the rate of 1:3 to 4. The gel
compound (option) can be used as it is.
4) Keep rotating the blade reel cylinder, and stop rotation when the contact sound
disappears. Put in a newspaper again to check the blade reel cylinder entirely for the
sharpness of each portion.
5) Repeat operations (3) and (4). When the blade reel cylinder and bottom blade are in
contact with each other uniformly, apply abrasive to the blade reel cylinder entirely for
final lapping.
6) After lapping, remove the abrasive with steam, etc.
Danger
Both blade reel cylinder and bottom blade are edged. Handle them
carefully.
Be careful of the fingers, which turn the blade reel cylinder, when cutting a
newspaper to check sharpness. Uniformly lap the right and left sides of
the bottom blade in contact with the blade reel cylinder, and the life of the
blade will be maximized.

1) Lightly engage the blade reel cylinder and bottom blade uniformly both sides (right and left).
2) Uniformly adjust the bottom blade on the right and left sides. Turn 10 blade support adjusting nut
P1 (1-53) clockwise for slight engagement, and turn it counterclockwise for firm engagement.
3) Lightly engage both sides to the extent that a newspaper will be cut sharply.
When the blade reel cylinder is worn and the spring pressure decreases, loosen the lock nut (1-
50) and turn right the threaded cutter adjusting tube (1-49) so that the spring pressure increases.
Move the brush from left to right
[IMPORTANT] Cam adjustment
