A Warning and Safety Instructions
1 General Information
All repairs should be performed by a trained technician in strict
accordance with national, state and local codes. Any repairs or
maintenance performed by unqualified personnel could be dangerous.
When servicing, modifying, testing or maintaining appliances, all applicord
laws, regulations and accident prevention guidelines must be observed.
All regulations of the appropriate utility supply companies and standards
relating to safety (not limited to electrical safety) are to be complied with.
Before any service work is started, the vacuum cleaner must be
disconnected from the power supply.
Even with the vacuum switched off, voltage may be applied to some components.
Do not leave the vacuum unattended when it is plugged in. Turn off and
unplug the vacuum before opening the cover.
After work has been completed, a visual as well as an operational check
should always be performed.
2 Cleaning and Care
2.1 Vacuums and Accessories
The vacuum cleaner and other plastic components can be cleaned using a
damp cloth or a cleaner made especially for plastics.
Warning!
Do not use abrasive, glass or all-purpose cleaning solutions, as these can
cause considerable damage to the plastic components of the vacuum or its
accessories.
2.2 Dust Compartment
The dust compartment can be cleaned using another vacuum, if available, or
a dry cloth or brush.
Monitor the bag change indicator and inspect all filters regularly. Replace
them when necessary according to the operating instructions.

When re-installing, the rubber seal must first be installed in the cover frame.
4.3 Cord Reel Removal
1. Remove the casing top. See Section 020-4.3.
2. Remove the cap. See Section 030-4.1.
3. Release the electronic retainer, Figure 010-3, Item 1, and tilt it upwards,
Figure 010-3, Item 2.
4. Remove the cover frame; see Section 020-4.5.

7. Disconnect the cord reel from the electronic.
8. Release all wires from their guides.
9. Remove the electronic retainer.
4.4 Cord Removal
Note:
Use only a genuine Miele cord for the correct vacuum model number.
Note:
Never replace the cord end.
1. Remove the cord reel. See Section 010-4.3.
2. Unwind the cord completely. See Figure 010-7.
Figure 010-7: Cord Reel, Unwound

Technical Information

S2 Canister Vacuums
3. Clamp the cord reel to the body of the cord reel assembly to immobilize it.
See Figure 010-8. Failure to clamp the cord reel can allow it to rotate,
changing the spring tension and affecting operation. The reel can also
separate from the body, releasing the tension spring. Always clamp the
reel to the body before performing any cord repair.
Figure 010-8: Cord Reel Clamped to Reel Assembly Body
4. Once the clamp is in place, remove the 2 T10 screws from the cord reel.
See Figure 010-9.
Figure 010-9: Screws Securing Cord Reel
5. Release the tabs holding the two halves of the cord reel together. See
Figure 010-10. The top of the reel will lift straight up.

Figure 010-10: Cord Reel Tabs
6. Remove the cord from the cord reel.
7. Install the new cord.
8. Reassemble the reel halves. Do not remove the clamp until the cord reel
halves are fully assembled.
9. When the reel has been reassembled, remove the clamp and retract the
cord slowly, leaving a 6” tail. Once the cord reel is installed in the vacuum
it is important to do an operational check and ensure that the cord
extends and retracts correctly.

2 Function
2.1 Bags
A clean bag is essential to the maximum efficiency of the vacuum. A clogged
bag can cause restricted airflow resulting in poor suction or, in extreme
cases, an overheat condition can occur resulting in the vacuum shutting off.
Changing the bag is relatively easy; the most important thing to remember is
to use the correct bag. A list of bags and the models in which they are used
can be found in the product line information in the operating manual.
2.2 Bag Change Indicator
Figure 020-1: Bag Change Indicator
To test the bag change indicator:
1. Connect the floor attachment to the suction hose.
2. Switch on the vacuum cleaner.
3. Set the selector to full power.
4. Lift the floor attachment from the floor. If the window in the bag change
indicator is completely red, then the bag must be changed. See Section
020-4.7 for instructions.
The display function is set for mixed dust (dust, hairs, threads, carpet fluff,
sand, etc.).
If large quantities of fine dust (e.g., from drilling holes in masonry, fine sand,
etc.) are vacuumed, the bag pores are quickly blocked. The bag change
indicator then indicates “full” even though it is not actually full. However, the
bag should still be replaced.
If large quantities of hair, carpet fluff, etc., are vacuumed, the indicator might
not react until the bag is stuffed full.

2.2 Filters
Miele canister vacuums use several types of filters (Super Air Clean, Active
Air Clean, Active HEPA) to provide a clean, healthy environment. See Figure
020-2. Vacuum model will dictate filter(s) type. See Table C-1.
Figure 020-2: Filter Types
Note:
Changing from one type of filter to another type is permitted. (e.g., Active Air
Clean to Active HEPA). See Section 020-4.10 for instructions.
