The appliance can only be started when you press the foot pedal fully downwards. The machine stops when you release the foot pedal. From he stationary escalator cleaner, de- tergent fluid (from the fresh water tank) is applied to the running travellator/ escalator. The rolling brushes brush the detergent againt the running direction into the ridges of the travellator/ escalator. In the same working step, the dirty detergent is sucked into the dirt water tank of the machine via the intake brushes. This appliance is suited for the commercial use, e.g. in hotels, schools, hospitals, facto- ries, shops, offices, and rental companies. Use this appliance only as directed in these operating instructions. – The appliance may only be used to clean the stepping areas of travellators/ escalators. – This unit is only to be used indoors. – The running or movement direction of the unit to be cleaned must be adjusted in such a way that the travellator/ esca- lator moves away from the machine. – To clean the escalator, place the ma- chine only at the lower end of the esca- lator. – The appliance may only be equipped with original accessories and spare parts.

Unloading Removing anti-frost agents 19EN– 5 DANGER Risk of injury! The device can become stuck to and carried away by moving walk- ways/escalators. Check the treads and groove profile for deformations before cleaning and remove any trapped objects found. In case of emergency, make sure that you know where the emergency stop button for the moving walkway/escalator is located. Cordon off the travellator/ escalator as long as cleaning operations are on and the stepping areas are still wet. Switch on the travellator/ escalator. Ensure that the running direction of the travellator/ escalator is away from the machine. Check whether the combs and the guide rails of the machine match the make of the travellator/ escalator. Re- place the combs and the guide rails, if required. Open the cover of the fresh water reser- voir. Fill in fresh water. ATTENTION Risk of damage. Only use the recommend- ed detergents. With other detergents, the operator bears the increased risk regarding the operational safety and danger of acci- dent. Only use detergents that are free from sol- vents, hydrochloric acid and hydrofluoric acid. Follow the safety instructions for using de- tergents. Note: Do not use highly foaming detergents. Pour in detergent. Close the cover of the fresh water res- ervoir. Drive the machine in front of the travel- lator/ escalator platform. DANGER Risk of injury! – Do not use the appliance on inclines. – Only use one foot to step on the foot pedal. The other foot must remain firmly and securely on the ground. – Always hold the push handle firmly with at least one hand. – Loose items of clothing or jewellery may be caught by moving parts of the mov- ing walkway/escalator. Therefore, re- move all jewellery and wear close-fitting clothing and sturdy footwear. The cleaning time depends on the level of dirt and is divided into three cleaning types. Use dry vacuum clean on the travellators/ escalators that have already been cleaned. Cleaning slighly dirty travellators/ escala- tors (normally, at short regular intervals). At this setting, the appliance works with re- duced quantity of water. The water pump works with regular strokes. Start up Preparing the travellator/ escalator Preparing the appliance Operation Cleaning types Dry vacuum cleaning Regular cleaning 20 EN– 6 Cleaning very dirty travellators/ escalators (normally done when the escalator has not been cleaned for a long time). Areas with heavy dirt and stains should ideally be cleaned manually. – First clear off loose, coarse dust manually. – Remove hard objects (such as stones) from the ridges of the steps. – Clean the front side of the escalator steps manually. – Clean the stepping areas in overlapping strips. To do that, first move the appli- ance from the working position and place it on the side. – Observe the steps while cleaning. They should be moist but not wet. There should not be any foam residue. – First do moist cleaning (with detergent liquid) and then dry (by setting the appli- ance to dry vacuum cleaning). – Then clean using clear water so as to remove detergent residues. DANGER Risk of injury and electric shock! Always route the extension cable so that it cannot be trapped or crushed and does not pre- sent a tripping hazard. Plug in the mains plug. Insert the end of the extension cable as a loop in the strain relief clamp. Lock the rear wheels. Place the machine on the platform in such a way that the front wheels do not touch the first step of the moving travel- lator/ escalator. Press pedal for lowering the brush head. The brush head will be lowered and the lock lever will arrest in its posi- tion. Press the foot pedal with one foot and while doing so move the machine a little back and forth towards the side. The machine will position itself centrally in the grooves of the steps; you will then hear a rustling sound. DANGER Risk of injury! The device must not be pushed any further onto the escalators than indicated. Otherwise there is a danger that the device will be carried away by the esca- lator. In the event of such a danger, push the escalator emergency stop button imme- diately. The cleaning head must lie flat on the esca- lator. Set the appliance switch to regular or basic cleaning. The machine is started. Basic cleaning Tips for cleaning Cleaning operations 21EN– 7 Note: The device switches off when the waste water tank is full.
