This electric tool complies with E.C. requirements in force relating to radio and TV interference.
Applications
Your new high torque drill has been specially designed for close-up precision work in confined spaces. It is supplied with 30
accessories and a variable speed transformer. The drill will enable you to carry out a variety of jobs, including drilling, grinding,
sanding, cutting etc. in a multitude of applications such as hobby work, electronics, D.I.Y etc.
Sources of Power
Your drill has a 12V motor which makes it safer and smaller than a mains powered drill. A transformer/rectifier is needed to step down
the voltage to 12V (RS stock no. 472-2776 is supplied with a transformer).
Mounting of Accessories
Your drill is supplied with a chuck. To insert or change accessories, hold the locking ring and undo the chuck or collet nut. Insert the
accessory shaft into the chuck or collet ensuring maximum shaft contact and then tighten up. (Do not use pliers)
Connecting your 12V Tool
IMPORTANT: When connecting your 12V tool to the transformer you need to be sure that the polarity is
correct. (Connect the (+) plug of the tool to the (+) output on the transformer)
You have been supplied with an adapter that can be used to allow the use of Minicraft 12V Tools with this
transformer.

The transformer is fitted with an internal overload cut-off system with automatic reset. This overload cut-off system protects your unit
from current loading and overheating. If the transformer is overloaded the overload system will be activated and the neon indicator
light will go out.
What to do if the overload cut-off system is activated
1. Any 12V tool connected to the transformer should be switched off.
2. Disconnect the transformer from the mains and then leave for 10 minutes. This allows the transformer to cool off and the
overload system to reset.
3. After the 10 minute cool off time has been reached the transformer can then be reconnected to the mains. If the LED
indicator re-lights this means the overload cut-off system is successfully reset and the transformer is now ready for use.
General useful hints
1. The drill will become warm after a certain period of constant working and should therefore be periodically switched off and allowed
to cool down.
2. The motor does not require maintenance, but the chuck and spindle should be oiled now and then to ensure smooth operation.
3. To ensure concentric drilling, it may be necessary to re-insert the drill bit into the chuck 2 to 3 times whilst turning it slightly. A
certain amount of practice is required to achieve this alignment.
4. Never apply too much radial pressure to accessory bits while grinding, cleaning or polishing. By doing so you will put a strain on the
bearing and spindle, adversely affecting the precision of the drill.
5. The efficiency of the drill will be impeded by overloading and in many cases this will reduce its
performance. Always work with a sensitive touch; you have a precision instrument in your hands.
6. When drilling into metal, mark the drilling point with a centre punch first, so the drill tip does not slip.
7. Always ensure that there is maximum contact between the accessory shaft and the chuck.
For your safety
a. Always wear safety glasses.
b. If you stall the drill, turn it off immediately.
c. The tool should be unplugged when changing accessories.
d. Periodically check collet nuts and chucks for tightness especially during prolonged use of the same accessory.
e. If the transformer overloads, switch off and unplug the transformer from the mains. A short period of cooling time should be allowed
(approx. 3 minutes) in order for the overload system to automatically reset. Work can then be continued.

Important Safety Instructions (For All Tools)
WARNING: When using Electric Tools, basic safety precautions should always be
followed to reduce risk of fire, electric shock, and personal injury, including the
following:
1. KEEP WORK AREA CLEAN. Cluttered areas and benches invite injuries.
2. CONSIDER WORK AREA ENVIRONMENT. Do not expose power tools to rain. Do not use power tools in
damp or wet locations. Keep work area well lit.
3. GUARD AGAINST ELECTRIC SHOCK. Prevent body contact with grounded surfaces. For example:
pipes, radiators, ranges, refrigerator enclosures.
4. KEEP CHILDREN AWAY. All visitors should be kept away from work area. Do not let visitors come into
contact with tool or cord.
5. STORE IDLE TOOLS. When not in use, tools should be stored in a dry place, locked-up out of reach of
children.
6. DON’T FORCE TOOL. It will do the job better and safer at the rate for which it was intended.
7. USE RIGHT TOOL. Do not force small tool or attachment to do the job of a heavy-duty tool. Do not use
tool for purpose not intended, for example, don’t use circular saw for cutting tree limbs or legs.
8. DRESS PROPERLEY. Do not wear loose clothing or jewellery. They can be caught in moving parts,
gloves and non-skid footwear are recommended when working outdoors. Wear protective hair-covering to
contain long hair.
9. USE SAFETY GLASSES. Also use face or dust-mask if cutting operation is dusty.
10. DON’T ABUSE CORD. Never carry tool by cord or yank it to disconnect from receptacle. Keep cord from
heat, oil and sharp edges.
11. SECURE WORK. Use clamps or vice to hold work. It’s safer that using your hand and it frees both hands
to operate tool.
12. DON’T OVERREACH. Keep proper footing and balance at all times.
13. MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for better and safe performance. Follow
instructions for lubricating and changing accessories. Inspect tool cords periodically and if damaged have
repaired by authorised service facility. Keep handles dry, clean and free from oil and grease.
14. DISCONNECT TOOLS. When not in use, before servicing, and when changing accessories, such as
blades, bits, cutters.
15. REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to see that keys and adjusting
wrenches are removed from the tool before turning it on.
16. AVOID UNINTENTIONAL STARTING. Don’t carry plugged-in tool with finger on switch. Be sure switch is
off when plugging in.
17. OUTDOOR USE EXTENSION CORDS. When tool is used outdoors, use only extension cords intended
for use outdoors and so marked.
18. STAY ALERT. Watch what you are doing. Use common sense. Do not operate tool when you are tired.
19. CHECK DAMAGED PARTS. Before use of the tool, a guard or other part that is damaged should be
carefully checked to determine that it will operate properly and perform its intended function. Check for
alignment or moving parts, binding of moving parts, mounting, and any other part that is defective should
be properly repaired or replaced by an authorised service centre unless otherwise indicated elsewhere in
this instruction manual/leaflet. Have defective switches replaced by authorised service centre. Do not use
tool if switch does not turn it on and off.
20. DO NOT OPERATE. Portable electric tools near flammable liquids or in a gaseous or explosive
atmosphere. Motors in these tools normally spark, and the sparks might ignite fumes.
