Warning!
Do only use the lock button if the tool is operated with the supporting stand. If a standstill caused
by the tool or a power failure occurs, do immediately loosen the lock button by pressing the on/off
switch in order to avoid the unintended restart of the tool (risk of injury).
The mixer has an electronic switch in order to regulate the speed level by keystrokes.
It is recommended to only use it when the machine is started or stopped in order to avoid
splashing material. If the continuous mode is operated with reduced speed, it leads to overstress
because the machine is not provided with enough cooling air and overheating will occur
significantly faster.
Care and Maintenance
Repairs shall only be carried out by qualified staff trained and experienced in this area.
The tool shall be inspected by a skilled electrician after every repair.
The power tool is designed to require only a minimum of maintenance and care. However, the
following work shall be carried out and/or the following parts shall be inspected regularly:
•
Do always keep the power tool and the ventilation slots clean.
•
Make sure that no foreign objects get into the power tool.
•
If the tool breaks down, the repair shall only be carried out by an authorised shop.
Information on noise and vibration
Measured values determined according to EN 60745
The A-weighted noise level of the tool is typically:
Sound pressure level (L
Sound power level (L
Uncertainty K
Wear ear protection!
Hand-arm vibration:
Hand-arm vibration is typically lower than 2.5 m/s².
Measured values determined according to EN 60745
The vibration emission level indicated in these instructions has been measured in accordance with
a standardised test method given in EN 60745 and can be used to compare one tool with another.
It is also suitable for a preliminary evaluation of the vibration emission level.
The vibration emission level set out in these instructions presents the main applications of the
power tool. If the power tool is used for other applications or with different tools or if maintenance
is not sufficient, the vibration emission level may vary. This may lead to a significantly higher
vibration emission level during the whole working period.
In order to be accurate, an estimation of the level of exposure to vibration should also take into
account the times when the tool is switched off and when it is running but not actually used. This
may significantly reduce the level of exposure to vibration during the whole working period.
Additional protective measures in order to protect the operator from vibration effects, e.g.
maintenance of power tools and tools, keeping hands warm, organisation of work processes, shall
be determined.
