Important! – Safety instructions for all tools
Warning: When using electric power tools, important safety precautions must always be

adhered to in order to reduce the risk of fire, electric shock and personal injury.
Please read the following carefully:

1. Keep work area clean. Untidy benches and work areas cause injuries.

2. Consider work area environment. Do not use power tools in damp or wet locations. Do
not expose power tools to rain. Keep work areas well lit.

3. Guard against electric shock. Prevent body contact with grounded surfaces. E.g.
radiators, pipes, refrigerator enclosures.

4. Keep children away. All visitors must be kept away from the work area. Do not let
visitors come into contact with the tool or extension cord.

5. Store idle tools. When not in use, tools must be stored in a dry place, out of reach of
children.

6. Do not force the tool. It will do the job at hand better and safer at the rate for which it
was intended.

7. Use the right tool. Do not force a small tool to do the job of a heavy duty power tool. Do
not use the tool for the purpose it is not intended for.

8. Dress properly. Do not wear loose clothing or jewellery, as these can be caught in
moving parts. Gloves and non-skid footwear are recommended when working outdoors.
Wear protective head cover to contain long hair.

9. Use safety glasses. Also use face and dust mask to guard against dust.

10. Do not abuse the cord. Never carry the tool by the cord or pull the cord to disconnect
the tool. Keep the cord away from heat, oil or sharp objects.

11. Secure your work. Use clamps or a vice to hold your work in position. It is much safer
than using your hand and it frees both hands to operate the tool.

12. Do not overreach. Keep proper footing and balance at all times.

13. Maintain tools with care. Keep tools clean for better and safer performance. Follow
instructions for lubricating and changing accessories. Keep hands dry, clean and free
from oil and grease.

14. Disconnect tools. When not in use, before servicing and when changing any
accessories.

15. Remove adjusting keys and wrenches. Have the habit to check and see that keys and
adjusting wrenches are removed from the tool before turning on.

1

16. Avoid unintentional starting. Do not carry plugged-in tool with finger on switch. Be sure
that the switch is off when plugging in.

17. Outdoor extension cords. When the tool is used outdoors, only use extension cords
intended for use outdoors and so marked.

18. Stay alert. Watch what you are doing. Use common sense. Do not operate the
tool when you are tired.

19. Check damaged parts. Before using the tool, a guard or other part that is
damaged, these must be carefully checked to ensure that the tool will perform
properly the intended function. Check for alignment of moving parts, binding of
moving parts, breakage of parts, mounting and any other condition that may
affect the tool’s operation.

20. DO NOT OPERATE porta ble electric tools near flammable liquids or in
gaseous or explosive atmospheres. Motors in these tools normally spark, and
the sparks may ignite fumes.

Multifunction power tool use

This rotary tool can be used for drilling, grinding, sanding and polishing, as well as engraving,
cutting and removing rust in tight spaces or inaccessible places. The tool can be used on
most metals, glass, wood and ceramics. For best performance and results, please keep the
speed as even as possible without exercising too much pressure. As a guideline, use the
tool at low speed for all large accessories, such as polishing for example, and at high speed
for smaller accessories such as those used for engraving. For grinding and engraving, hold
the tool as if it were a pen.

Multifunction power tool start-up

Never start up or stop the tool when the accessory is in contact with the piece to be worked
on. Hold it firmly and press the ON/OFF switch. The tool will run continuously until the switch
is turned to OFF position. The speed can be adjusted while the tool is running.

Speed adjustment

The multifunction power tool is equipped with speed control. Do not change the speed while
the tool is working. The speed switch is located on the rear of the tool. Turn it to increase or
reduce speed. Use the tool at low speed for polishing and similar operations, but use higher
speed for drilling or cutting action.

Important general safety tips!

1. The tool should be unplugged when changing accessories.

2. If the tool stalled, switch the power off immediately.

3. Periodically check the tightness of your collet chuck, especially during prolonged

use of the same accessory

4. After use, always disconnect your power tool.

5. Do not undertake to repair the power tool by yourself.

6. Do not leave your tool unattended while switched on.

7. Do not use or store your tool in damp or wet conditions.

Useful hints & tips

1. Your rotary tool will become warm after prolonged use, please switch off and allow
to cool down after long term use

2. To ensure smooth running, the spindle should be oiled periodically.

2

3. Do not apply too much radial pressure to the accessory bits while polishing, cleaning,
sanding or grinding. By doing this you will put a strain on the spindle and adversely
affect the precision of the tool.

4. Always work with a sensitive touch so as not to impede the efficiency of your mini tool.

5. When drilling metal, always mark the drilling point with a center punch first, so that
your rotary tool does not slip.

6. Always ensure that you have maximum contact between the accessory shaft and the
collet chuck.

Placing accessories into the tool

Always switch the tool off first. Hold the locking button at the front of the tool and undo the
collet chuck (anti-clockwise). Insert the collet that matches the shaft size of the accessory to
be used. Place the collet nut over the collet and then insert the accessory shaft into the collet
chuck ensuring maximum shaft contact. Then tighten up the collet nut. (DO NOT USE
PLIERS).

purposes only.

Important! Working on a high load whilst at low speed can cause motor burnout.
Overload The motor of this tool may be damaged if overloaded. Manual pressure on this
tool will not result in faster operation. Forcing the tool will only result in reduced efficiency
and could cause motor burnout, substandard work, shorter tool life and possible injury.

Avoiding Motor Damage: If you are running the tool continuously at low speed, it’s
important to occasionally take the tool off load. Running the tool off load at full speed for
approximately one minute creates a cooling air flow for the motor.

Carbon Brushes (fig. 7)

The carbon brushes are an integral component in the
efficient running of the motor. These are consumable spare
parts that must be replaced when they are worn to 4mm.

NOTE: Worn carbon brushes should only be installed by an
authorized power tool repair agent.

NOTE: After replacing the carbon brushes there may be increased sparking. This is normal
and should pass after a short period of time.

NOTE: After new carbon brushes have been installed, run the Mini-Grinder off load for
several minutes to allow the new brushes to bed in before use.

How to replace motor carbon brush
