3 General Safety 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.
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 product's life please ensure that the product 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 wet. 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.
Risk of fire as a result of heat build-ups possible. 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. The cable cross-section must be
at least 1.5mm2.
Safety guidelines for persons
Be attentive and pay attention to what you are doing, act rationally when working with an
electrical appliance. Do not use the appliance when tired or under the influence of drugs,
alcohol or medication.
Just one moment of inattention whilst using the appliance can result in serious injury.
Make sure the appliance cannot be switched on unintentionally. Double check that the
main switch is in the "OFF" position before inserting the plug in the socket. Connecting
the appliance to the power supply while it is switched on can cause an accident.
General Safety Instructions

no longer be switched on or off is dangerous and must be repaired.
Keep unused electrical devices away from children. Do not allow the appliance to be
used by persons who are not familiar with it or persons who are not familiar with this user
guide. Electrical appliances are dangerous when in the hands of inexperienced persons.
Treat the device with care. Check that moving parts are functioning properly and do not
block; check whether parts are broken or damaged and impairing the functioning of the
device. Have any damaged parts repaired before using the appliance. Many accidents
are caused by poorly-maintained electrical appliances.
Use electrical appliances, accessories etc in accordance with these instructions and in a
manner that is specified for this particular appliance type. When using the appliance,
please take into account the working conditions and the work being carried out. Using
electrical appliances for other uses than that intended can lead to hazardous situations.

parts. In this way you can ensure that the appliance remains safe.
3.3 Operator's duties

thorough cleaning by appropriately trained and authorised operating personnel. NOTE: This
is only permitted by the manufacturer's service department during the guarantee and
warranty period.
Any repairs and/or overhaul during the warranty period may only be carried out by the
manufacturer´s service department.
