Breathing protection must be worn if the power tool
is used without a dust removal system for work that
creates dust.

7.3 Adjusting the grip 6
WARNING
Do not attempt tp adjust the position of the grip
while the tool is running. Check to ensure that
the grip is engaged in one of the three possible
positions.
To allow the power tool to be used comfortably in all
positions, the grip can be pivoted through 90° to the
left and the right.
1. Disconnect the supply cord plug from the power
outlet.
2. Release the locking lever by pulling it back.
3. Pivot the grip to the left or right as far as it will
go.
4. Secure the grip in position by closing the locking
lever.
NOTE The power tool cannot be switched on as
long as the grip is not locked in one of the three
possible positions.

7.4 Working with the power tool

NOTE
Apply only moderate pressure.
NOTE
The direction in which the cut is made is important.
The disc must always cut in counter-rotating mode.
Failure to observe this point presents a risk of the
cutting disc being forced uncontrollably out of the
kerf.
NOTE
Special discs should be used for working on non-
ferrous metals (e.g. aluminium).
NOTE
When the power tool is used in conjunction with
the DC-EX hood and a suitable vacuum cleaner, the
volume of dust emitted can be greatly reduced.
NOTE
The cutting disc may overheat and suffer damage
when cutting very hard mineral materials with a high
hard pebble content. A trail of sparks right round the
circumference of the cutting disc is a sure indication
of this. In this case, the cutting operation should be
interrupted and the cutting disc allowed to cool by
running the power tool under no load for a short time.
