Location of components

Operation

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 renewal work..

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.

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 brushes with different brush lengths, bristles and bristle materials.

Filling fresh water

• Unlock coupling (16) and separate from fresh-water tank (17).
• Clip in the coupling into the hose braket (18).
• Draw fresh-water tank forward on the side plate (19) and withdraw from machine.
• Remove lid (20) and fill in a maximum of 20 litres of fresh water.
• Use the cleaning in the recommended mixing proportion (see operation instructions ).

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.

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.

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.

Preliminary work

All foreign bodies such as: cigarette packages, cans, etc. must always be removed 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, otherwise there is danger of it being drawn into the machine!

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.

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 secured against accidental starting ! Remove escalator keys!

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 tobe 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 spindles (22) and the green light in the AUTO-START-button (9) blinks!

Select cleaning programms

The machine is provided with 3 cleaning programmes, which have been tested and optimised by columbus.. An ideal cleaning performance is achieved with a minimum use of water.

Programm 1: Quick cleaning cycle

(Duration of the cleaning cycle 15 seconds)

• Put Key switch (5) on „1“.
• Press Automatic ON (10).

Programm 2: Maintenance cleaning cycle

(Duration of the cleaning cycle 27 seconds)

• Put Key switch (5) on „1“.
• Choose program „2“ with the mode switch (14).
• Press Automatic ON (10).
• Switch from program 2 to program 1 during the cleaning cyrcle: Same process as program 2.
• Switch from program 1 to program 2 during the cleaning cyrcle: Same process as program 1.

Programm 3: Intensive cleaning cycle (Duration of the cleaning cycle 39 seconds)

• Put Key switch (5) on „1“.
• Choose program „3“ with the mode switch (14).
• Press Automatic ON (10).
• Switch from program 3 to program 2 during the cleaning cyrcle: Same process as program 3.
• Switch from program 2 to program 3 during the cleaning cyrcle: Same process as program 2.

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).

The pre-selected programme can now be started. When the cleaning cycle has been completed, 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.

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 started 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

The cleaning process can then be started for the right side and take place as described above.

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.

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.

Emptying the dirty-water tanks

(see Fig. 12 Remove dirty water tank and Fig. 13: Insert dirty water tank)

• Set key switch (5) to “0” position.
• Draw the dirty-water tank (21) forward and set down onto the side plate (19).
• Put in the suction tubes into the hose bracket (18)
• Remove tank lid (28) and put it to the side.
• Grip tank on the carrying-troughs and dispose of dirty water according to the relevant environment regulations.

All valid regulations regarding waste water must be strictly observed when the dirty water is being dumped!

• Place dirty-water tank (21) onto the side plate (19) and insertion area.
• Replace tank cover (28).
• Adapt the suction tubes (take care of the coorect fitting; the tubes have to be adapted so that the do not cross each other!)
• Shove in tank (21) and check secure mounting.
• Set key switch (5) to position “1”.
• Start suction with START/STOP key (9).
• Check fitting of tank cover (28)!
• Switch off suction with START/STOP key (9).
• The work can now be continued.

Ending the cleaning process

• Move machine as described in Chapter 3.11 with the escalator to the lowest completely extended step.
• The machine is then raised over the lifting spindle drive (22).
• If the escalator is going downwards, leave the escalator at the lower end, while making sure that:

When the machine is driving over the rim comb the rear axle along with the brake (29) must always be raised in order to prevent the machine catching on the escalator’s rim combs While removing the step 100 off the escalator put a piece of carton under the brake so it cannot hook in the comb of the escalator. Take out the machine with transport trolley (see Chapter 3.16 Use of the transport trolley) and bring to place of storage.

Use of transport trolley

Preparation for transport

For transport, the machine is removed from the transport trolley with the shaft in front after the fixing axle (31) has been removed and driven into the shaft (see Fig. 15: Moving into transport position).

Before the travelling mechanism is driven from the stairs, the rollers on the transport trolley must always be secured with the brakes!

After the fixing axle (31) has been inserted and secured, the travelling mechanism can be drawn in and the machine thus placed on the transport trolley. The fixing axle (31) must be secured against slipping out by means of the supplied permanent cotter pin ! The guide rollers of the transport trolleys allow the machine to be manoeuvred easily (see Fig. 16: Machine in transport position).

Use of transport trolley for maintenance

In preparation for maintenance, the machine is removed from the transport trolley with the shaft in front, after the fixing axle (31) has been withdrawn, and driven into the shaft (see Fig. 17: Moving into maintenance position).

• Before the travelling gear is drawn in, the roller of the transport trolley must always be secured with the brakes!
• After the fixing axle (31) has been inserted and secured again, the travelling gear can be drawn in to about a third its length and the machine then swung into the maintenance position on the trolley.
• The fixing axle (31) must be secured against slipping out by means of the supplied permanent cotter pin!
• Before turning the machine remove both tanks (17; 21) and their covers (20; 28). Otherwise they can be damaged! In this way maintenance and cleaning work can be carried out easily and quickly (see Fig. 18: Machine in maintenance position).

Maintenance / Care

Safety measures during cleaning and maintenance of the machine

• Before any maintenance or cleaning work is carried out, the machine must be separated from the mains with the main switch being set to “0“ and the mains plug disconnected.

This will prevent accidents caused by electrical voltage or moving parts.

• During cleaning or maintenance work on the machine, when parts are being replaced or new equipment fitted for a new function, care must be taken that the machine can not accidentally start, roll or turn over and that no parts can fall down or flap closed. If the operator has any questions or doubts regarding safety, he must request advice from the manufacturer or the relevant sales agent before starting the machine.

Daily care

• Examine the power cable for any damage.
• Always empty the dirty-water tank (21) following use and rinse thoroughly with water
• Inspect brushes (1) and clean.
• Rinse out suction basin (32).
• Clean stripping brush (33).

Weekly care

• Clean and lightly lubricate the extended lifting spindles (22).
• Check suction tubes for leaks.
• Check seal strips (34) and renew if necessary (Fig. 19: Seal strip)

Maintenance after 30 service hours

Maintenance work may be carried out by trained personnel only.

• Remove suction basin (32) and stripping brush (33) and rinse (Fig. 18: Seal strip)
• Check chains (35) for correct tension and, if necessary, tighten with chain adjuster 44) (see Chapter 4.6.1 Tightening the chain and Fig. 20: Chain drive /Spraying nozzle).
• Clean chains (35) and treat with a chain spray.
• Check spray nozzles (36) and clean if necessary.
• Check glide rails (25) on the right and the left. Replace if showing signs of wear (Fig. 19: Seal strip).
• Check sliding elements of the step adjustment device (23 and 24). Replace in case of wear.
• Check seal strip (34) and renew if necessary (Fig. 18: Seal strip).

Maintenance after 100 service hours

Maintenance work may be carried out by trained personnel only.

• Maintenance work in this case should be carried out as after 30 service hours, but here the chains (35) and chain wheels (37) must be checked for wear and replaced if required (see Fig. 21: Chain drive / spray nozzle).
• The brushes (1) must be dismantled and inspected (Fig. 1: Brush assembly). New brushes must be fitted when necessary.
• Clean collecting container (39) under the suction device (38).
• Check all electrical components.

Anumal maintenance

An electrically driven machine must be examined every year in accordance with VDE 702 or some comparable international standards.

This examination must be carried out by a service technician trained columbus.

Tightening the chain

(see Fig. 21: Chain drive /spray nozzles)

The chains must be tightened so that the centre of each chain can be raised by hand between the chain wheels by approx. 3 mm (“A”) or pressed together by 4 – 5 mm (“B”). The chain can be tensioned by adjusting the pressure spindle (26) in the direction of the arrow. The suspension chains on the left and right (“A”) must always have the same tension!

The wearing limit of a chain has been reached when the distance “s” between the 1st and 12th roller exceeds 135.0 mm; see Fig. 22: Wear measurement chain drive. With a brand new chain this dimension “s” should measure 131.4 mm. These values are valid for all 3 chains.

Cleaning and replacing fresh water nozzles

(see Fig. 21: Chain drive / spray nozzle)

• Screw off coupling ring (16).
• Remove pressure spring (41), spray nozzle (36) and ball (40).
• Clean spray nozzle, using only instruments without sharp edges.
• Re-assemble fresh-water nozzle as shown in illustration, while making sure:

The spray nozzles must be aligned in their mounting according to the turning safety device! The coupling ring (42) should only be twisted on manually!
