General safety instructions
To use this tool properly, you must observe the safety regulations, the
assembly instructions and the operating instructions to be found in
this Manual. All persons who use and service the machine have to be
acquainted with this Manual and must be informed about its potential
hazards. Children and infirm people must not use this tool. Children
should be supervised at all times if they are in the area in which the
tool is being used. It is also imperative that you observe the accident
prevention regulations in force in your area. The same applies for
general rules of occupational health and safety.
Warning. When using power tools, basic safety precautions should
always be taken to reduce the risk of fire, electric shock and personal
injury. Also, please read and heed the advice given in the additional
important safety instructions.
1. Keep the work area clean and tidy. Cluttered work areas and
benches invite accidents and injury.
2. Consider the environment in which you are working. Do not use
power tools in damp or wet locations. Keep the work area well lit.
Do not expose power tools to rain. Do not use power tools in the
presence of flammable liquids or gases.
3. Keep visitors away from the work area. All visitors and onlookers,
especially children and infirm persons, should be kept well away from
where you are working. Do not let others in the vicinity make contact
with the tool or extension cord.
4. Store tools safely. When not in use, tools should be locked up out
of reach.
5. Do not force the tool. The tool will do the job better and safer
working at the rate for which it was designed.
6. Use the correct tool for the job. Do not force small tools or
attachments to do the job best handled by a heavier duty tool.
3 4 5
Never use a tool for a purpose for which it was not intended.
7. Dress correctly. Do not wear loose clothing or jewellery. They can be
caught in moving parts. Rubber gloves and non-slip footwear are
recommended when working outdoors. If you have long hair,
wear a protective hair covering.
8. Use safety accessories. Safety glasses and earmuffs should
always be worn. A face or dust mask is also required if the
drilling operation creates dust.
9. Do not abuse the power cord. Never pull the cord to
disconnect the tool from the power point. Keep the cord away
from heat, oil and sharp edges.
10. Secure the work piece. Use clamps or a vice to hold the work
piece. It is safer than using your hand and frees both hands
to operate the tool.
11. Do not overreach. Keep your footing secure and balanced at
all times.
12. Look after your tools. Keep tools sharp and clean for better
and safer performance. Follow the instructions regarding
lubrication and accessory changes. Inspect tool cords periodically
and, if damaged, have them repaired by an authorised service
facility. Inspect extension cords periodically and replace them
if damaged. Keep tool handles dry, clean and free from oil
and grease.
13. Disconnect idle tools. Switch off the power and disconnect
the plug from the power point before servicing, when changing
accessories and when the tool is not in use.
14. Remove adjusting keys and wrenches. Check to see that
keys and adjusting wrenches are removed from the tool before
switching on.
15. Avoid unintentional starting. Always check that the switch
is in the OFF position before plugging in the tool to the power
supply. Do not carry a plugged in tool with your finger on the
switch.
16. Use outdoor rated extension cords. When a tool is used
outdoors, use only extension cords that are intended for
outdoor use and are so marked.
17. Stay alert. Watch what you are doing. Use common sense. Do
not operate a power tool when you are tired.
18. Check for damaged parts. Before using a tool, check that there
are no damaged parts. If a part is slightly damaged, carefully
determine if it will operate properly and perform its intended
function. Check for alignment of moving parts, binding of moving
parts, breakage of parts, proper mounting and any other conditions
that may affect the operation of the tool. A part that is damaged
should be properly repaired or replaced by an authorised service
facility, unless otherwise indicated in this Instruction Manual.
Defective switches must be replaced by an authorised service
facility. Do not use a tool if the switch does not turn the tool on
and off correctly.
19. Guard against electric shock. Prevent body contact with
grounded objects such as water pipes, radiators, cookers and
refrigerator enclosures.
20. Use only approved parts. When servicing, use only identical
replacement parts. Use an authorised service facility to fit
replacement parts.
Warning. The use of an accessory or attachment, other than those
recommended in this Instruction Manual, may present a risk of

Operation
• Melbourne • Perth • Auckland • Hong Kong • Shanghai
• Taipei • New York • Verona • London • Paris
WARNING. Before connecting a tool to a power source (power
point receptacle, outlet, etc.) be sure that the voltage supply is
the same as that specified on the nameplate of the tool. A power
source with a voltage greater than that specified for the tool can
result in serious injury to the user, as well as damage to the tool.
If in doubt, do not plug in the tool. Using a power source with a
voltage less than the nameplate rating is harmful to the motor.
Switch on
1. Set the variable speed dial to 1 and push the on/off switch (3)
to “I”, the machine is in continuous operation, and will start
at minimum speed.
Switch off
1. Reset the variable speed dial (4) to 1 and push the on/off
switch to position “0”.
Varying the speed
1. You can use the variable speed dial to alter the speed of the
collet, as follows:
• Position 1-Slow
• Position 3-Medium
• Position 6-Fast
2. Select the correct speed for the work and type of bit you are
using. In general, lower speeds are best suited for large tools
and higher speed for smaller tools.
Holding the tool
• Small milling cutters/grinders pencils - high speed
• Large milling cutters/grinders pencils - low speed
1. For jobs such as milling or engraving where precision is required,
hold the mini-drill like a pen.
2. For heavier work like cutting or grinding hold the machine in
the palm of your hand.
Changing accessories
1. Make sure that the machine is switched off and the plug
removed from the power before you commence changeover.
2. Loosen and tighten collet fully using the 2 in 1 Wrench provided. (always
ensure bits are tight before commencing any work with your tool).
3. Press and hold down the spindle lock button (5) and unscrew
the Collet nut (6).
4. Select a suitable Collet for the accessory to be used and insert it
in the collet nut shaft.
5. Turn the Collet nut in an anti-clockwise direction to loosen
and, when the bit is in place, turn the Collet nut in clockwise
direction to lock it in place, whilst depressing the spindle lock.
6. Make sure that the bit is inserted as far as possible. Having too
much shaft exposed could cause it to damage or bend.
Locating a cutting/sanding disc
1. Locate the disc holder in the Collet nut.
2. Remove the screw from the end with the 2 in one wrench
provided, and insert the screw through the cutting disc.
3. Replace the screw and tighten, attaching the cutting disc onto
the holder. (Do not over-tighten)
Locating a sanding drum
1. Loosen the small screw in the top of the holder.
2. This allows the rubber to slacken.
3. Slide the sanding drum onto the holder.
4. Secure the sanding drum in place by tightening the screw causing
the rubber drum to bulge and grip the drum. (Do not over-tighten)
Maintenance
1. Store the machine, instruction manual and, where necessary,
the accessories in the original packaging. In this way you will
always have all the information and parts ready to hand.
