3. Switch the sharpener on and

press the tool evenly onto

the sharpening stone. Move

the tool sideways across the

stone. Always try and use the

full width of the stone so the

wheel wears evenly.

Note.

DO NOT push hard. This

is a sharpening process, not a

grinding process. Light pressure is all that is required.

4. On the completion of the sharpening process, turn off the

sharpener at the on/off switch (5) and remove the plug

from the power point. Proceed to remove, empty and

clean the water tray then remount it as detailed in the

"Assembly" section.

Note.

It is not advisable to leave the sharpening wheel

sitting in water when the sharpener is not in use.

Note.

New sharpening wheels can show traces of the

production process. You can substantially increase the life

and performance of the wheel by dressing the front face

before use. See the "Maintenance" section.

Honing

Honing is the practice of polishing a cutting edge using a

very fine abrasive such as a lapping paste. It is used after a

sharpening stone to smooth out any irregularities and create

a razor-like finish to the cutting edge.

CAUTION.

Never hone against the direction of rotation.

Note.

Ensure safety glasses are worn during the sharpening

and honing process.

Honing must only be performed

working with the direction of the

leather wheel. For this reason

the tool support bar needs to be

mounted in the rear mounting

holes prior to honing.

Setting up the honing tool support bar

1. To set up the tool support and the adjustable tool holder

for honing, follow the instructions as per the

for sharpening"

section of this manual except that the

tool support bar (7) must be fitted into the rear mounting

holes instead of the top mounting holes. The bar should

extend out over the honing wheel, and it should be fully

inserted. The bar can be withdrawn later if the angle

requires an outward position, but in most conditions the

bar will need to be fully inserted.

2. Impregnate the leather honing wheel (2) first with a light

machine oil (not supplied) then apply the lapping paste (11).

3. Switch on the machine and use a flat device (ruler, knife

or paint mixing paddle) to distribute the lapping paste

evenly into the leather using circular motion. Repeat this

practice after every 5 to 10 tool sharpenings.

Note.

This will increase the life of the leather and the quality

of results.

4. Set the adjustable tool holder as described in

for sharpening"

section. Using the tool holder will

ensure a constant and more even honing process.

Note.

To achieve the best result keep the tool mounted in

the tool holder, located in the required angle/position at all

times. DO NOT apply the tool being honed to the honing

wheel without the tool being inserted into the tool holder.

Now that you have correctly set up to hone you can begin

the honing process.

Honing process and technique

When honing NEVER hone against the direction of

the wheel. Press the blade to be honed evenly on to the

honing wheel near the cutting edge and move the blade

across the face of the honing wheel; ensuring that at least

half of the width of the honing wheel is always in contact

with the blade to be honed.

Allow the honing wheel to do the honing for you.

apply excessive force to the wheel.
