3Safety instructions
This section covers residual risks and hazards associated with the intended use of the appliance. We have
provided a list of all generally valid safety instructions which must be followed.
In the following section, safety information relating to a particular operation or situation is placed before the
appropriate operation step or description of the situation.
The information provided here such as ‘Basic rules of conduct’, ‘Operator's obligations’ etc. only refers to the
legally required observance of requirements such as the Workplaces Ordinance (ArbStättV) according to
German law.
3.1 General behaviour
This appliance meets the current state of the art and complies with all acknowledged technical
safety-related regulations. Nevertheless hazards may still arise.
Only use this appliance when it is in fault-free condition and according to the
instructions in this user guide.
During all phases of the appliance's life please ensure that the appliance is safely
integrated into its environment.
Refrain from rearranging or changing the device.
3.2 On use of electrical appliances
Safety instructions according to EN 60745-1:
Work area
Keep your work area clean and tidy. A messy or unlit work area can cause accidents.
Keep children and other people away from the area when work is being carried out.
Electrical safety
The plug on the unit must fit in the socket. Do not modify the plug in any way. Never use an adapter
in combination with earthed appliances. Using an unmodified plug and a suitable socket will reduce
the risk of an electric shock.
Avoid bodily contact with earthed surfaces such as pipes, heating units, cookers and refrigerators.
The risk of an electric shock is greater when your body is earthed.
Keep the device away from rain or moisture. Allowing water to get into an electric appliance will
increase the risk of electric shock.
Do not use the cable for anything other than the intended purpose to disconnect the plug from the
socket. Always remove whilst holding onto the plug. Keep the cable away from heat, oil, sharp edges
or the moving parts of other appliances. Using damaged or tangled cables increases the risk of
electric shock.
When working with an electrical appliance outdoors, only use extension cables which are permitted
for outdoor use. Using an extension cable suitable for outdoor use reduces the risk of electric shock.
Potential risk of fire due to heat build-up. Unwind the cable from the cable drum to prevent a possible
heat build-up and/or cable fire. The coupling must have splash protection, must be made of rubber or
be rubber-coated.
