5. Safety precautions
5.1 Basic information concerning safety
CAUTION: To avoid the risk of electric shock, injury or
fire,thebasicsafetyprecautionslistedbelowmustalways
be observed when using electric tools.
Inadditiontotheinformationrelevanttosafetygivenin
eachofthesectionsoftheseoperatinginstructions,the
following points must be strictly observed at all times.
5.2 Safety precautions at the workplace
●Ensure that the workplace is well lit.
●Ensure that the workplace is well ventilated.
●Keep the workplace tidy. Objects which could cause
injury should be removed from the working area.
Untidiness at the workplace can lead to accidents.
●Secure the working area (cordon off if necessary).

4
vided with a means of removing and collecting dust,
check that this is connected correctly and used as
intended.
●To avoid tripping and falling when working, always
leadthe supply cord, extension cord and dust extrac-
tion hose away to the rear.
●Concealedelectric cables or gas and water pipes pre-
senta serious hazard if damaged while you are work-
ing.Accordingly, check the area in which you are work-
ingbeforehand (e.g. using a metal detector). External
metalparts of the tool may become live, for example,
