Caring for the environment
8
Disposal of the packing material
The packaging is designed to protect the appliance from damage during transportation.
The packaging materials used are selected from materials which are environmentally
friendly for disposal and should be recycled.
Recycling the packaging reduces the use of raw materials in the manufacturing process
and also reduces the amount of waste in landfill sites.
Disposing of your old appliance
Electrical and electronic appliances often contain valuable materials. They also contain
specific materials, compounds and components, which were essential for their correct
function and safety. These could be hazardous to human health and to the environment if
disposed of with your domestic waste or if handled incorrectly. Please do not, therefore,
dispose of your old appliance with your household waste.
Please dispose of it at your local community waste collection / recycling centre for elec-
trical and electronic appliances, or contact your dealer or Miele for advice. You are also re-
sponsible (by law, depending on country) for deleting any personal data that may be stored
on the appliance being disposed of. Please ensure that your old appliance poses no risk to
children while being stored prior to disposal.

Finger guard
The finger guard is a safety feature that must be checked daily for proper functioning be-
fore the machine is used.
Risk of injury due to lack of finger guard function.
A malfunctioning finger guard function can lead to serious injury.
Shut down the flatwork ironer immediately.
Contact the Miele Customer Service Department without delay.
Ensure that the flatwork ironer is not put into operation by other persons and draw atten-
tion to the potential hazard.
After being switched on, the ironer will only switch to normal operating mode if the finger
guard has been activated properly after switching on the ironer. Otherwise, the ironer will
switch off again after a short amount of time.
“Finger guard” display symbol
If the display symbol is flashing, gently press the underside of the finger guard once.
If fingertips become trapped between the roller and the finger guard, the ironer will be
stopped immediately and the heater plate disengaged. At the same time, the symbol will
light up continuously. Press the button to switch the ironer back on.
While the ironer is operating, do not use the finger guard intentionally to interrupt the
ironing process.
Press the button to interrupt the ironing process.

Guide to the machine

Emergency switch-off
The emergency off switch puts the ironer into a safe state in the event of danger or in order
to prevent danger.
The ironer features two emergency off switches – one on the front of the left side column
and one on the back of the right side column.
Emergency stop switches on the side columns
Pressing the emergency stop switch will immediately stop the roller and disengage the
heater plate from the roller.  appears in the display.
Once the emergency stop switch has been pressed, twist it in a clockwise direction to re-
lease it again.
Do not use the emergency off switch to switch off the flatwork ironer normally.
The emergency stop switches are intended for use only in hazardous situations.

Using for the first time
15
Cleaning and waxing before use
It is essential to clean and wax the heater plate before it is used for the first time (see
“Cleaning the heater plate” and “Waxing the heater plate” in “Cleaning and care”).
Clean the heater plate by passing the cleaning cloth offset through the ironer across the
entire width of the roller multiple times.
After cleaning the heater plate, wax it using the ironer waxing cloth and suitable ironing
wax. Use the ironing wax sparingly to avoid the ironing cloth becoming too smooth.

Preparing the laundry
16
Only iron suitable fabrics
Only clean fabrics that have been washed using water may be ironed. Before ironing, make
sure the fabrics are suitable for the ironing process. Suitable fabrics can be identified as
such by the corresponding care symbol on the label (,  or ).
Residual moisture
Laundry items with 25–50% residual moisture are perfect for ironing because this ensures
an excellent finish. The residual moisture is absorbed by the fabric fibres, which makes
them easier to smooth.
The ideal level of residual moisture depends on the fabric’s properties.
If the laundry is rinsed in the final cycle using warm water, the laundry will still be warm and
will have lower residual moisture. Therefore, laundry rinsed with warm water takes less
time and energy to iron.
Sorting the laundry
Sort the laundry according to type and fabric before starting to iron. At the same time,
please observe the instructions on the laundry care label. We recommend sorting the
laundry in the following order:
Type of material Symbol Temperature
Nylon and other synthetics 100–110°C
then
Woollens, silks  111–150°C
followed by
Cotton, linen  151–185°C
Always follow the instructions on the care label when ironing laundry.
Starched laundry should always be ironed last.
Otherwise, any remaining starch residue on the heater plate may have a negative effect
when ironing other laundry items.

Using the ironer
17
Making the appliance ready for use
Turn on the on-site main switch for the power supply.
Press the button to switch on the ironer.
The red symbol flashes.
Now gently press the underside of the finger guard.
The ironer switches to normal operating mode.
The ironer is only ready for use if the finger guard has been actuated properly. Otherwise,
the ironer will switch off again after a short amount of time.
The red symbol will appear in the display and the heater plate will heat up.
Risk of burns when touching the hot heater plate.
When the machine has heated up, there is a danger of burns on the edge of the heater
plate. Warning labels on the outer casing of the heater plate indicate the danger of
burns.
Avoiding touching the edges of the heater plate.
Wait until the selected temperature has been reached.
The button begins to flash as soon as the minimum temperature has been reached.
The flatwork ironer is ready for operation when the set temperature is reached and the
symbol no longer appears in the display.
Now press the flashing button to start up the ironer.
The ironer is now ready for use.
Ironing
Whilst ironing, the laundry is fed into the ironer using the laundry infeed table. The ironed
laundry is removed from the other side. The laundry pickers pick off the laundry from the
roller after ironing. The laundry can then be folded together on the outfeed table.
Risk of burning due to hot laundry and hot edges of the heater plate outfeed.
While the ironer is in use, the heater plate becomes very hot. Ironed laundry may also be
very hot when it emerges from the heater plate.
Always take care when removing ironed laundry from the appliance.
Do not touch the edges of the heater plate outfeed.
Ironing temperature
The ironing temperature should be selected according to the type of fabric being ironed.
Fabric Symbol Temperature Preset value
Nylon/artificial silk 100–110°C 110°C
Silks/woollens  111–150°C 125°C

Feeding in laundry
Press the button to start the ironing process.
The heater plate engages and the roller begins to rotate.
Risk of damage as a result of incorrect laundry in-feed.
If laundry items with buttons are incorrectly fed into the ironer, they may be damaged or
torn off when the item is passed into the heater plate.
Laundry with buttons must be inserted into the ironer so that the buttons are facing the
roller and can be pressed into the roller’s ironing cloth during ironing.
Place a cloth over zips, metal buttons and metal hooks before ironing to protect the
heater plate.
Never iron metal or plastic clasps of any kind, or very bulky buttons (e.g. ball-shaped
buttons).
Align the laundry item parallel to the roller on the laundry infeed table.
Smooth the item of laundry.
Feed the item of laundry evenly into the ironer.
Do not feed small items of laundry into the ironer on only one side.
If laundry in-feed is on just one side, the heat will only be used on one side and the load
only exerted on the roller padding on one side. If the laundry in-feed continues to be on
one side only, this will be indicated by an audible signal and the red symbol or
symbol appearing in the display.
Use the entire roller width wherever possible and distribute small items of laundry evenly

Picking laundry out of the ironer
Risk of burning due to hot edges of the heater plate outfeed.
While the ironer is in use, the heater plate becomes very hot. Ironed laundry may also be
very hot when it emerges from the heater plate.
Always take care when removing ironed laundry from the appliance.
Do not touch the edges of the heater plate outfeed.
The picker springs on the laundry picker band separate the ironed laundry from the roller.
The laundry can then be removed from the ironer.
Risk of fire due to laundry self-ignition.
Hot laundry could self-ignite and cause a fire.
Allow the ironed laundry to cool down before packing or stacking it.
If a picker spring is loosened from its position, the ironer must be switched off. The picker
spring then needs to be moved by hand to the original position of the laundry picker band.
