5 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.
5.1 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.


 Do not make any conversions or modifications to the appliance.
5.2 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 persons at a distance when using the product.
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 appliance away from rain or damp. Allowing water to get into an electric
appliance will increase the risk of electric shock.
•
••
• Do not misuse the cable by using it to remove 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 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 spool to prevent any
heat build-up 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 1.5 mm
2
.
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
Rieber GmbH & Co. KG 9
Careful handling and use of electrical appliances
•
••
• Never use an electrical appliance with a faulty switch. An electrical appliance which can
no longer be switched on or off is dangerous and must be repaired.
•
••

•
••
• Handle the appliance carefully. Make sure all moving parts of the appliance work
perfectly and are not jammed, also check whether any parts are broken or damaged to
the extent that operation of the appliance is impaired. 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 guidelines 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.
