1 Safety instructions
1.1 Preliminary remarks
The escalator deep cleaning machine step 100 was manufactured according to state-of-the-
art technology and in compliance with all relevant regulations. This, however, does not guar-
antee that some other unavoidable dangers for persons and property can occur. All person-
nel working with this machine must therefore read and follow these operating instructions,
and in particular the safety regulations, with great care.
These operating instructions must remain at the machine for use by the operator. Each oper-
ator must receive thorough instruction on handling and working with the machine.
1.2 Owner’s duties
In accordance with EU directive on the use of operating equipment 89/655/EEC Art. 6(1) and
7 and EU framework directive 89/391/EEC Art. 1(1) and Art. 6(1), the owner of the equipment
is obliged to instruct all persons, particularly with regard to safety, who will be authorised to
work on assembly, operation, maintenance, repair or dismantling of the machine.
The owner is also obliged in accordance with EU directive on the use of operating equipment
89/655/EEC Art. 4a to inspect the machine before start-up, following repair work and follow-
ing faults or malfunction.
1.3 Intended and specified use
The escalator deep cleaning machine step 100 is exclusively intended for basic and mainte-
nance cleaning of indoor and outdoor escalators. Any use beyond this stipulation must be
considered as contrary to the manufacturer’s intentions. The manufacturer will not be liable
for any damage resulting from such work; all risk in this case will be borne exclusively by the
operator. Correct use of the machine also includes compliance with the conditions of opera-
tion and maintenance stipulated by the manufacturer.
The escalator deep cleaning machine step 100 is not intended nor suitable for clean-
ing hazardous dirt.
The machine may only be used with the cleaning liquid approved by the manufactur-
er.

hands.
When the machine is being disconnected from the power network, only the plug itself
may be pulled - never the power cable.
The machine may be repaired or opened only by qualified electricians.
If work on the opened machine with connected current is absolutely neces-
sary, such work may be carried out only by a qualified electrician who is famil-
iar with all attendant dangers and the relevant work stipulations (VDE0100).
When work is carried out on machine or parts when live, only tools specially
intended for this purpose may be used.
1.6 Modifications and changes to the machine
It is forbidden for reasons of safety to carry out modifications to this machine. Any unauthor-
ised modifications to the machine automatically invalidate all liability claims against the man-
ufacturer for any damage caused by the modified machine.
Original parts and accessories have been specially designed for this machine. Parts and fit-
tings made by other manufacturers have not been tested by us and are therefore not ap-
proved for use. Assembly and installation of such parts could impair the safety and the per-
fect functioning of the machine. Columbus expressly refuses to accept liability for any dam-
age resulting from the use of non-original parts and accessories.
1.7 General safety instructions
When the machine is not in use, its must always be locked away and the key re-
moved.
If it is not possible to lock away the machine, some other suitable measures must be
taken to prevent unauthorised use.
Neither the electrical nor mechanical safety devices on the machine may be changed
or put out of action.
It must be ensured that no other persons, in particular children, are in the vicinity of
the machine when it is in operation.
The machine may only be transported in elevators whose permitted load is adequate
for this purpose.
1.8 Safety instructions for mains-operated machines
Care must be taken that the mains cable incurs no damage by being crushed, torn, frayed,
driven over, etc. This connection must be examined regularly for damage, bare points,
scorched areas, etc. The machine may not be used unless the mains connections is in per-
fect condition. The plug must always be disconnected prior to any cleaning or maintenance
work on the machine, or when accessories are being fitted and replaced. When parts, such
as brushes, mains connection cables, plugs, etc. are being replaced, all technical data pro-
vided by the manufacturer must be observed and only original spare parts used; otherwise
safety of the machine could be impaired. If the power cable is damaged, it must be replaced

step 110

3 Operation
3.1 Before start-up
All local safety regulations and instructions must be observed for each start-up.
The escalator must be inspected jointly with the party responsible for the escalator, who
should also be informed of any discoloration or paint stains etc. caused by repair and renew-
al work..
3.2 Assemble brushes
If brushes (1) have not yet been installed in the guide rail (2), the lid (3) on the opening for
replacing brushes (4) in the left side wall should be opened (see Fig. 1: Brush assembly).
If possible, brushes of the same design (brush length, hardness etc.) should
not be installed directly behind each other in order to avoid unbalance effects
and to achieve an ideal cleaning result!
Make sure that one of the lids (3) is closed while putting the brushes into the
machine.
Figure 1 Brush assembly
The procedure below should be followed:
Insert power plug.
Set key switch (5) to "1".
Raise machine [pushbutton (6) on operating console (46)].
Move rail in the opening for replacing brushes (4) (pushbutton (7) Touch operation for
bush).

Attention! When pushing the button the brushes start immediately to move.
Set key switch (5) to "0".
Shove in brush (1) until it hits against the right side wall.
Set key switch (5) to "1".
Move next rail completely in the opening for replacing brushes (4) (pushbutton (7)
touch operation for brush).
Set key switch (5) to "0".
Repeat this procedure until all brushes have been inserted.
Then screw on lid (3) once more.
Use only original columbus brushes: the size and shape of these have been
tested and are adjusted to fit the escalator! A set of brushes consists of brush-
es with different brush lengths, bristles and bristle materials.

Each time the fresh-water tank is being filled, the dirty-water tank (21) should
also be emptied. See Chapter 3.14 Emptying the dirty water tanks.
Figure 3 Fill up fresh warter
3.4 Preparations on site
The cleaning date should be co-ordinated with the maintenance personnel (possibly process
electrician) in charge of the escalator.
The safety manager should also be informed if necessary.
Have the escalator switched off by the relevant specialists and secured
against being switched on by accident!
Remove escalator key!
The operator must plug in the mains cable for the machine, or a suitable socket must be
shown to him.
The operator must furthermore obtain instruction on manual control of the escalator or else
ensure that some person familiar with the workings of the escalator is available near by at all
times.
3.5 Safety measures on site
All unauthorised persons must be prevented from approaching the entrances at both ends of
the escalator by means of safety measures (e.g. red-and-white barrier chains).

The machine, the transport trolley and, when available, accessories trolley are to be placed
in the cordoned-off level area at the bottom of the stairs to prevent any unauthorised use.
3.6 Preliminary work
All foreign bodies such as: cigarette packages, cans, etc. must always be re-
moved before any work commences!
Any objects jammed in the machine, such as small stones, bits of glass, etc.
are a significant impediment to achieving a good result. Care must therefore
be taken that all such objects are removed in advance. The handheld cleaning
equipment is ideal for this purpose!
Remove any dirt from the grooves in the steps with the 4 cm hand rake before vacuuming,
brushing or sweeping clean.
Handheld cleaning equipment should not be left lying on the escalator, other-
wise there is danger of it being drawn into the machine!
3.7 Working instructions
The detergent applied to the escalator surface will lead to danger of slipping!
Shoes with non-slip soles must therefore always be worn during work on the
stairs!
Scratching or erosion on the escalator steps caused by wear, corrosion or material faults can
not be repaired.
3.8 Positioning the machine on escalator
The machine with extended lifting spindles (18) should then be shoved into the escalator and
moved by authorised escalator operators to the first completely extended step (Fig. 4:Fixing
the machine).
The escalator is then stopped completely.
Ensure that the escalator is switched off by the relevant personnel and se-
cured against accidental starting !
Remove escalator keys!

Figure 4 Fixing the machine
3.9 Setting step height
The machine is in danger of falling if the travelling supports (23) and safety
supports (24) are not adjusted properly to the step height of the escalator to
be cleaned.
Move machine to the first completely extended step.
Fix the machine in the middle of the escalator.
Pull the star handle (47) down. Then lower the machine. The machine has to stand
on the rear legs now. So the gliding rails (25) do not touch the escalator completely.
Open the attachement screw and check if the travelling support (23) and the safety
support (24) touch the escalator.
Move the star handle (47) to a higher position (move it a bit more to the top than the
highest distance between the escalator and the gliding rail (25)).
Lift the machine (6) and lower (11) it. Now the whole gliding rail (25) have to touch the
escalator. If not then please move the star handle (47) more to the top and repeat the
process.
Thighten the attachement screws again and make sure that the travelling support (23)
and the safety support (24) touch the escalator.
Make sure that the machine is resting uniformly on the two travelling strips and
all four supports and that the wheels are approx.. 3-4 mm distant from the
step!
If this is not the case, the adjustment procedure must be repeated!
Incorrectly adjusted travelling supports (23) will mean that the operator will
have to use more force! In addition the travelling supports (23) brake earlier.

Start the cleaning operation.
It will be possible to start the cleaning process only when the running gear has
been driven to the point where the limit switch is activated at the lifting spin-
dles (22) and the green light in the AUTO-START-button (9) blinks!

3.11 Cleaning the escalator
In order to achieve an ideal moisture content on the brushes, the first step should be cleaned
twice at the beginning of the cleaning operation. After the machine - lying on the left side of
the escalator - is shoved into the escalator step until the wheels stop until the seal strip (34)
is arrested (Fig. 9: Positioning the machine).
Figure 8 Lowering the machine
Figure 9 Positioning the machine
10

step 110
19
The pre-selected programme can now be started. When the cleaning cycle has been com-
pleted, the machine is raised (Fig. 9: Raising the machine).
When raising the machine, the operator must ensure that the glide rails do not
hang on the inside walls of the escalator.
Figure 10 Raising the machine
The machine is then shoved forward again until the wheels stop on the next highest step
(Fig. 4: Fixing the machine), and then lowered again. The machine can now be shoved on
the glide rails into the new working position (Fig. 9: Positioning the machine).
Repetition of the procedure described above will allow the escalator to be cleaned from the
bottom to the top completely-extended step.
Always ensure that the power cable is disconnected and wound up before the
escalator is started again to avoid accidents!
The switched-off and lowered machine is then driven downwards with the escalator to the
position of the last extended step.
After the cable has been connected once more, the procedure described above can be start-
ed anew and the escalator cleaned again up to the top completely extended step. After the
machine has been run from the lower to the highest completely extended step, one side of
the escalator will have been cleaned.
The machine must now be shifted from the left to the right (Fig. 11: Shifting the machine).
Therefor lift the machine about 3 to 5 cm and push it on the gliding rails to the other side.
Do not push the machine on the gliding rails! They can be ruined.

step 110
20
Figure 11 Shifting machine
The cleaning process can then be started for the right side and take place as described
above.
3.12 Subsequent cleaning
Manual cleaning equipment has been developed by columbus by means of comprehensive
practical tests.
With this equipment, any subsequent cleaning that may become necessary, such as major
soiling on the edges and the joining areas between two steps, can be carried out easily.
The manual cleaning equipment manufactured by columbus is particularly
suitable for minor subsequent cleaning.
3.13 Refilling with fresh water
The operator must carry out regular checks at the transparent feeder tube for fresh water
(27) to ensure that the machine is receiving a supply of detergent solution. If bubbles appear
in the tube or if no liquid can be seen, the fresh-water tank is empty and must be refilled.
Let the machine stand in the lowered position on the escalator and fill fresh water along with
cleaning agent according to instructions in Chapter 3.3.
When the fresh-water tank is being filled it is essential that the dirty-water tank
is emptied.
