GENERAL SAFETY RULES

WARNING: WHEN USING ELECTRIC TOOLS, MACHINES, OR EQUIPMENT,
BASIC SAFETY PRECAUTIONS SHOULD ALWAYS BE FOLLOWED TO REDUCE
THE RISK OF FIRE, ELECTRIC SHOCK AND PERSONAL INJURY.

1. KEEP WORK AREA CLEAN. Cluttered areas invite injuries. Keep work area well lit.

2. NEVER use power tools in damp, wet, or poorly lit locations. Don't expose to rain. Do
not use electrically powered tools in the presence of flammable gases or liquids.

3. KEEP CHILDREN AWAY. Children must never be allowed in the work area. Do not let
them handle machines, tools, or extension cable.

4. STORE IDLE EQUIPMENT. When not in use, tools must be locked up in a dry location to
inhibit rust. Always lock up tools and keep out of reach of children.

5. DO NOT FORCE THE TOOL. It will do the job better and more safely at the rate for
which it was intended.

6. DRESS PROPERLY. Do not wear loose clothing or jewellery which could be caught in
moving parts.

7. USE EYE AND HAND PROTECTION. Always wear approved impact safety goggles.

8. DO NOT ABUSE THE POWER CABLE. Do not yank it to disconnect it from the socket. Do
not carry tools by the cable.

9. DISCONNECT POWER. Unplug when not in use, before servicing, and when changing
accessories.

10. AVOID UNINTENTIONAL STARTING. Be sure the switch is in the OFF position when not in
use and before plugging in.

11. STAY ALERT. Watch what you are doing, use common sense. Do not operate any tool
when you are tired.

12. CHECK DAMAGED PARTS. Before using any tool, any part that appears damaged
should be carefully checked to determine that it will operate properly and perform
its intended function. Do not use the tool if the switch does not turn on and off
properly.

13. GUARD AGAINST ELECTRIC SHOCK. Prevent body contact with grounded surfaces
such as pipes, radiators.

14. REPLACEMENT PARTS AND ACCESSORIES. When servicing, use only identical
replacement parts. Use of any other parts will void the warranty. Only use
accessories intended for use with this tool.

WARNING! Read these electrical safety instructions thoroughly
before connecting the product to the mains supply.

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.

WARNING! The wires in the power cable of this product are
coloured in accordance with the following code:
Blue = Neutral Brown = Live

If the colours of the wires in the power cable of this product do not correspond with the
markings on the terminals of your plug, proceed as follows.

•The Blue wire must be connected to the terminal which is marked N or

coloured Black.

•The Brown wire must be connected to the terminal which is marked L or

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 approximately 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.
