ELECTRICAL CONNECTIONS
Before switching the product on, make sure that the voltage of your electricity supply is
the same as that indicated on the rating plate. This product is designed to operate on
230VAC 50Hz. Connecting it to any other power source may cause damage.
This product may be fitted with a non-rewireable plug. If it is necessary to change the
fuse in the plug, the fuse cover must be refitted. If the fuse cover becomes lost or
damaged, the plug must not be used until a suitable replacement is obtained.
If the plug has to be changed because it is not suitable for your socket, or due to
damage, it should be cut off and a replacement fitted, following the wiring instructions
shown below. The old plug must be disposed of safely, as insertion into a mains socket
could cause an electrical hazard.

markings on the terminals of your plug, proceed as follows.
• The wire which is coloured Blue must be connected to the terminal which is
marked Nor coloured Black.
• The wire which is coloured Brown must be connected to the terminal which is
marked Lor coloured Red.
We strongly recommend that this machine is connected to the mains supply via a
Residual Current Device (RCD)
If in any doubt, consult a qualified electrician. DO NOT attempt any repairs yourself.

OPERATIONS
PROPERLY SHARPENED BITS
Your bit is properly sharpened when it has the following characteristics.
• A sharp point in the center of the bit.
• Two sharp and equal cutting edges
• Two trailing edges that are slightly lower than the cutting edges.
SHARPENING PROCEDURE
1. Place sharpener on a flat, sturdy surface and plug in.
2. Put a single drill bit (HSS only) into
the appropriate hole
3. Turn the unit on.
• Exert a slight downward
pressure onto the bit and rotate
the bit back and forth about 20
degrees while sharpening.
• The bit must be kept in motion
whilst in the machine.
4. Turn unit off after approximatley 5-10 seconds of sharpening.
• Examine bit according to the “Sharpening Hints” section below.
5. Ensure both sides of the drill bit are sharpened using the same amount of
time and pressure.
6. Repeat the above steps as necessary.
7. Do not run the machine for longer than 2 minutes at a time.
SHARPENING HINTS
• If the tip of bit starts to turn blue, it is overheating. Reduce the
amount of pressure and sharpening time. Cool the bit in water
between sharpening cycles.
• If one edge is longer than the other, sharpen the drill bit a little more.
• If you are sharpening a broken (rather than blunt) bit and the time
required to restore the shape is too long, rough the bit into shape first
using a bench grinder.

ADJUSTING THE GRINDING WHEEL
1. Turn the grinding wheel height
adjustment knob clockwise to
raise the wheel.
• This will give you an aggressive
cutting action. This is also useful
when you are working with
short bits.
2. Lower the wheel by turning the
adjusting knob to the left.
• This will produce a finer ground
edge, though it will take longer and require more repetitions.
