19 Leica SP 9000 – Automatic knife sharpener
The fine honing procedure is identical to coarse honing with three excep-
tions:
1. Lower honing plate to fine honing position by turning honing dial on the
left-hand side of the control panel fully to the right. Note red dot.
2. Apply a ribbon of the Leica Fine Abrasive to the plate. After extensive
testing, it was determined that the Fine Abrasive is a superior abrasive
and produces a finer polished facet. This new abrasive has the following
advantages.
a. Improved performance. Sharpening in the fine honing cycle will be con-
siderably reduced. Failure to use the Leica Fine Abrasive may result in the
accumulation of metal particles on your hone plate which will damage
the edge.
b. Leica Fine Abrasive is in suspension and will not settle out. It requires no
shaking or stirring.
c. Leica Fine Abrasive is water soluble and hone plate cleaning is accom-
plished easily under running water. If a film remains on the knife, it should
be carefully wiped with a soft cloth.
3. Set timer to 10 minutes and push red fine honing button in the centre of
the control panel. Note the solenoid, which applied pressure to the knife
in coarse honing, is not engaged. After the 10 minute period, examine the
knife and continue additional honing if necessary.
