9. Operation
All operations described in this manual must be carried out with
sufficient water in the trough to ensure the stone remains wet
during use. This is to ensure no damage to the sharpening stone
or items being sharpened occurs.
Fill the water trough with cold or room temperature water to the level of the
lip as shown in
Fig 9.1
.
With the speed control knob set at the lowest speed, turn the machine on
using the switch on the front,
Fig 9.2
.
The speed of rotation can be increased to compensate for the
wear of the stone. Increasing the speed as the stone becomes
smaller will retain the sharpening speed. The speed can also be
increased to sharpen more quickly.
As the wheel turns it will absorb water. Slowly add water to the trough as
the stone absorbs it until the water level remains constant.
Remove the water trough when the machine is not in use. If the
trough is left on, the bottom of the wheel will sit in water and
become unbalanced.
Trueing the Stone
The stone should be trued before use so it is parallel with the support arm as
shown in
Fig 9.3
. This will ensure accurate results.
If the stone is new it may already appear parallel to the support bar but
it is recommended to carry out the trueing procedure regardless as any
inaccuracies that are not visible to the naked eye will be corrected.
Trueing the stone also ensures that the stone is concentric to its shaft.
Ensure the tip of the tool is secured in place as shown in
Fig 9.4
by using a
6 mm hex wrench to tighten the securing screw.
Mount the support arm in the upper position.
Place the guide bar on the support arm with the trueing bar beneath it as
shown in
Fig 9.5
. The guide bar must be facing towards the front of the
machine and the tip of the tool facing towards the rear of the machine as
shown.
