■ Adjusting cutting sharpness
!
This mower is shipped from the factory with the gap between the blades and the lower blade set to its
greatest distance, to prevent damage by the blades during transport. Therefore, it is necessary to adjust
this gap before performing grass cutting work.
!
If the cutting sharpness is poor during use of the mower, it is necessary to sharpen the blades and then
adjust the gap between the blades and the lower blade again.
To adjust the gap between the blades and the lower blade, follow the procedure under "Adjusting the
blades and lower blade" on this page.
!
If the cutting sharpness is not improved by adjusting the gap between the blades and the lower blade, per-
form wrapping (polishing) on the blades. See "Adjusting cutting sharpness with wrapping (polishing the
blades)" on page 30.)
!
After adjusting the gap between the blades and the lower blade and adjusting the wrapping, if grass that
has been cut forms lines or blocks, contact a Shibaura business or sales office for assistance.
〈Adjusting the blades and lower blade〉
!
Before adjusting the blades and lower blade, tear newspa-
per into 50mm strips.
1. Tilt the mower back on a level surface, until the stand is
on the ground so that the mower will not move.
!
Place a weight on the handle to prevent the mower from
falling forward.
!
When rotating the blades, be sure to use the blade align-
ment tool. Do not touch the blades directly with your
hands.
2. Insert the newspaper strips between the blades and the
lower blade in three locations at the center, left, and right
sides of the blades, use the "blade alignment tool" to turn
the blades from top to bottom and test the cutting sharp-
ness.
!
If the newspaper strips are not cut, the gap between the
blades and the lower blade is too wide.
!
If the gap is too wide, rotate the lower blade adjustment
handles (left and right) to narrow the gap.
Warning
!
Be sure to stop the engine, and disengage the
main clutch, blade clutch, and work roller clutch
before making adjustments.
!
Be sure to use the blade alignment tool to turn
the blades.
!
Do not directly touch the blades.
