A Warning and Safety Instructions
1 General
Service and repair work should only be carried out by suitably qualified
persons in accordance with all appropriate local and national safety
regulations.
Servicing, modification, testing and maintenance of electrical appliances
should only be carried out in accordance with all appropriate legal
requirements, accident prevention regulations and valid standards.
Do not work on the iron while it is carrying voltage. If this becomes
unavoidable, as in the process of locating faults, put extra safety measures
into place.
Before any service work is started, the machine must be disconnected from
the power supply.
Even with the machine switched off, supply voltage may be applied to some
components.
A general visual check should always be carried out.
After work has been completed, a touch current measurement should be
carried out on all accessible conductive parts that are not connected to
ground.
Danger!
There may be a risk of injury due to sharp edges. Protective gloves and
goggles should be worn and the edge protection, mat. no. 05057680,
should be used.
Danger!
Do not connect the rotary iron to an extension cord. Extension cords do not
guarantee the required safety of the appliance (e.g., danger of overheating).
Note:
If it is necessary to change the plug or power cord of the rotary iron, please
take note of the following color codes of the wires:
Green/yellow = Ground
Blue = Live 1
Brown = Live 2
Warning!
This appliance must be grounded.

B 890/B 990
2 Touch Current Measurement
Note:
Touch current measurement should be carried out on all accessible
conductive parts that are not connected to ground.
Warning!
Touch current measurement should only be carried out after the ground
connection of the appliance under test has been checked and found to be
satisfactory!
Dangerous voltages may exist on defective machines as well as on
accessible conductive parts that are not connected to ground!
Note:
No touch current measurement is necessary.
3 Risk of Injury Due to Tilting Mechanism
Warning!
When working on the appliance, the table and stand may tilt together/apart
unintentionally and this could cause injury.
The ironing table and stand are linked via a tilting mechanism. In its
transport (upright) position, the tilting mechanism is under tension; in its
working (horizontal) position, the tension in the table spring is released.
Before working on the appliance, tilt the ironing table into the working
(horizontal) setting and lock it in place.
When working under the ironing table, tilt the complete appliance
onto its back.
