Tips and notes for selecting the correct speed level
•
Select a high speed level for cutting, forming, chamfering
or milling grooves in the wood, and for sanding or grinding
wood or metal.
•
If you wish to cut plastics or other materials with a low
melting point, select a low speed level.
•
For drilling into wood, select a low speed level, in order to
prevent the tool from being overheated
•
For polishing, buffing and cleaning with a wire brush,
select the lowest speed level 1 or MIN, in order to prevent
the brush from damage by bristles coming loose from the
brush holder.
•
For milling or drilling into non-ferrous metals, e.g.:
aluminium, copper, lead, zinc alloys, select a low speed
level. Additionally use a cutting oil or another suitable
lubricant (not water) in order to prevent chips from settling
on the cutting edges of the tool, and to prevent the tool
from being overheated.
As an orientation for selecting the right speed level, you can use
the table below:
Speed
Speed
Min
5,000 rpm
1
9,000 rpm
2
15,000 rpm
3
17,000 rpm
4
20,000 rpm
5
22,000 rpm
Max
25,000 rpm
Info
Even with lower speed values, you should work without
pressure. Applying higher pressure to the workpiece
will not improve the result. Use a different tool or
another speed setting to obtain the desired result.
Operation
Tips and notes on handling the cordless grinder
General information:
•
Keep the venting slots clear to prevent the motor from
overheating.
•
Check the tool in the tool holder for proper fit before every
application. The tool must be firmly locked in place in the
tool holder.
•
Before every application, make sure that you have selected
the correct tool and the correct speed for the intended use.
By adapting the speed to the task you have planned and to
the m to be machined, better results can be obtained.
•
Always hold the tool away from your face. Parts of
damaged accessories might come loose when high speeds
are reached.
•
Before using the tool, you should get a feel for the tool.
Take the tool into your hand and familiarize yourself with
its weight and centre of gravity. Use some scrap material
to practise a bit and to learn how the tool responds with
different speed settings.
•
For tasks requiring precision, like for example engraving,
polishing or sanding, you can also hold the tool between
your thumb and index finger like a pen. The tapering of the
housing on the lower part of the tool serves this purpose.
Cutting:
•
Only use intact, flawless cutting discs. Bent, blunt or
otherwise damaged cutting discs could break.
•
Never use the cutting disc for roughing!
•
Only advance moderately during operation and make sure
that the cutting disc does not get jammed.
•
Do not slow down the decelerating cutting disc by pressing
against the side of the disc.
•
Always move the cutting disc through the workpiece in
reverse rotation.
•
Hold onto the tool with both hands.
Sanding:
•
Maintain a consistent grinding pressure to increase the
lifetime of the abrasive wheels and abrasive belts.
•
You'll obtain better results if the machining process not
only involves one single work cycle, but if you move over
the surface several times with the tool.
