Inserting and Removing Sharpening Modules
The tool MUST be switched OFF and disconnected from the electrical supply when
attaching or removing sharpening modules. • It is recommended to fasten the tool to a
flat and stable surface, such as a bench. Use the 4 mounting holes for this and 5mm countersunk type
fasteners. • The retaining clip and sharpening modules are constructed from plastic – do not use excessive
force when inserting and removing sharpening modules.
The tool is equipped with three specialised sharpening modules for various sharpening tasks. The
sharpeners slide down over the grinding wheel and are held in position by guide slots in the tool body and
the retaining clip. The tool can "hold" all sharpeners as it has similar guide slots on each side. To insert a
sharpening module:
1. Align the mounting "rails" (A) on the edges of the sharpening module with the guide slots (B) in the tool
body on either side of the grinding wheel.
2. Slide the sharpening module down into the tool until it "clicks" into place. When correctly inserted, the
retaining clip will prevent the module from being removed [a small amount of vertical movement of the
module may be noticed if you pull it upward – this is normal].
To remove a sharpening module:
1. Press down on the retaining clip (C) just enough for it to disengage from the sharpening module and hold
it there.
2. Pull the sharpening module from the tool, then release the retaining clip.

Sharpening Drills
The tool is suitable for sharpening high speed steel (HSS) and hardened steel drill bits to a nominal
118° included angle that is ideal for "normal" drilling into wood, plastic, aluminium, steel etc. It is
NOT designed for sharpening carbide-tipped masonry bit, wood bores, counter-boring and counter-sinking
tools etc. • The tool is suitable for drill diameters of 3mm (7/64") to 10mm (3/8"). • If the drill is broken,
roughly shape the drill to a point using a bench grinder before using the sharpener. • For drill bits that are
damaged or severely blunted, it may take several uses of the sharpener to rectify.
1. Insert the drill sharpening module into the tool.
2. Lift the drill bit holder (A) from the sharpening module and loosen the clamping screw (B) so the drill bit
can be inserted.
3. Insert the drill bit (C) into the holder and tighten the clamping screw just enough to hold the bit but still
allow it to be easily moved.
4. Insert the bit holder into the drill setter (D). Ensure that the slots on the sides of the bit holder engage
with the "rails" in the drill setter.
5. Hold the "V" block (E) against the bit holder, then push forward lightly on the drill bit and slowly rotate it.
When the drill bit flutes are on the left and right sides and the bit is as far into the "V" block as it will go,
the angle of drill rotation is correct.
6. Release the "V" block, then move the drill forward (do not rotate it) until the end of the drill bit reaches
the top of the "ramp" of the metal drill stop (F). This sets the correct distance for the drill bit to protrude
from the holder.
7. Tighten the drill holder clamping screw. Be sure not to allow the drill
to move or rotate, then remove the drill holder from the drill setter.
8. Switch the tool ON, then gently insert the bit holder into the drill
guide (G). Ensure that the slots on the sides of the bit holder
engage with the "rails" in the drill guide. The protruding end of the
drill should be resting on the metal bar at the end of the drill guide
and just touch the grinding wheel.
9. Smoothly move the grinding table (H) back and forth until there is no
longer any grinding noise or sparks.
10. Carefully lift the bit holder out of the drill
guide, then turn it over, insert it into the drill guide
and sharpen the other side of the drill bit.
When finished, the point where the drill flutes
meet should be centred and the cutting edges should be straight (no chips etc) and
equal in length.

Sharpening Scissors and Knives
The tool is suitable for sharpening steel scissors with straight, non-scalloped blades.
1. Insert the scissor sharpening module into the tool.
2. Switch the tool ON.
3. Open the scissor blades (A), with the bevelled cutting edge towards the grinding wheel. Holding the
scissor firmly, lower the blade into the scissor blade slot (B) so the pivot end of the blade is nearest the
grinding wheel.
4. Evenly and with a light, steady pressure, draw the scissor blade across the grinding wheel (C) for the full
length of the blade – pivot to tip. Repeat until the blade has a straight and sharp edge (no chips etc).
5. Repeat the sharpening process for the other scissor blade.
To sharpen knives:
1. Hold the knife firmly, and bring the handle-end of the knife blade (D) to the knife slot (E).
2. Angle the knife blade with the slot then gently lower it until the bevelled edge of the blade contacts the
grinding wheel (C).
3. Evenly and with a light but steady pressure, draw the knife blade back across the grinding wheel until it
is fully removed. Repeat until the blade has a straight and sharp edge (no chips etc).
4. Repeat the sharpening process for the other side of the knife blade, using the opposite knife slot.

Sharpening Chisels
For chisels that are damaged or severely blunted, it may take several uses of the sharpener to
rectify.
1. Insert the chisel sharpening module into the tool.
2. Place the chisel (A) on the chisel bed (B) so it is hard up against the guide at the end of the bed and
held firmly by the magnets (C). For narrow chisels, clip the narrow chisel guide (D) to the bed. This
ensure that the chisel can be held by the magnets.
3. Set the required angle of the chisel bed, by loosening the angle adjustment locking screw (E), then tilting
the bed to match the existing angle of the chisel bevel (the bed can be set at any angle between 20° and
40°). When set, tighten the locking screw.
4. Position the chisel so it will just contact the grinding wheel (F).
5. Switch the tool ON.
6. Evenly and with a light, steady pressure, slide the chisel bed back and forth across the grinding wheel for
the full length of the chisel. Repeat as required, moving the chisel in towards the grinding wheel a small
amount each time, until the chisel has a straight and sharp edge (no chips etc).
7. Repeat the sharpening process for the other side of the chisel.
