DUPLEX ESCALATOR BASE 350
1.1 CONGRATULATIONS ON HAVING CHOSEN DUPLEX MACHINES
These are the main characteristics of DUPLEX machines:
•Cleaning of any type of flooring thanks to a patented centrifugal system which allows dirt
to be recovered automatically and in real time;
•Great ease of handling thanks to the possibility of orientating the handle to change the
cleaning direction;
•Easy access to ‘critical’ points (escalator edges, corners, grooves and joints);
•Quite operation.
The experience and know-how gained over our years of production (tens of thousands of
machines in various models), the testing and application in different environments combined with
the expertise of our Engineers have allowed us to improve our product constantly. We were able
to achieve perfect cleaning results even in the deep grooves in the steps of escalators and reach
the side edges, which is still extremely difficult for other escalator cleaning machines.
While cleaning moving escalators, DUPLEX escalator cleaning machines remain still
and stable in their position thanks to the especially patented self-guiding system.
Professional models equipped with a full set of accessories and special trolleys have been
created from two simpler and cheaper machine models. Apart from facilitating the transport of
the appliance within the workplace, these also allow for easy positioning of the machines
themselves on the steps of escalators in motion, resulting in minimal cleaning times.

1.8 HOW TO USE
WARNING
Before inserting the cable plug into a power point which must be
earthed, ensure that the handle is in the rest (upright) position.
IT IS RECOMMENDED THAT YOU LUBRICATE THE CONVEYOR BELTS WITH
DUPLEX SILICONE SPRAY BEFORE STARTING UP THE MACHINE.
HOW TO CLEAN AND WASH ESCALATORS AND MOVING WALKWAYS
Use a Duplex ESCALATOR BASE 350
with an external wet and dry vacuum cleaner
(not supplied with the Base model)
Fit the special brushes provided, with their
equidistant bristles to reach right down into the
tracks forming the stair tread of the escalator
steps.
The pitch of these tracks or channels may vary
from manufacturer to manufacturer.
The brushes of the DUPLEX ESCALATOR Figure 1.5
BASE machines are made from a combination
of special plastic materials with no abrasive
coating, ensuring that no damage is caused to the metal steps of escalators or moving walkways.
WARNING:
Good cleaning results and a longer lifespan of the brushes can only be
achieved if the bristles can enter into the stair tracks or channels
precisely. The use of inappropriate brushes cannot only compromise
the cleaning quality but also damage the brushes.

AUTOMATIC MOTOR PROTECTION "MOTOR PROTECTOR" MP
The “Motor Protector” is a safety device which stops the machine in case conditions occur
that overload the electric motor (e.g. foreign bodies caught in the brushes which can prevent
their rotation, poor supply of power, overheating, etc.).
WARNING:
Disconnect the machine from the power socket before removing any
foreign bodies caught in the brushes.
After checking and possibly eliminating the cause which led to motor overload, press the
“Motor protector” button (after about 60 seconds) to restore machine operation.

DUPLEX ESCALATOR BASE 350
1.9 HOW TO WASH ESCALATORS AND MOVING WALKWAYS
1st PHASE - DRY BRUSHING
IMPORTANT:
All dry dust will be sucked up using this procedure, which is essential
to prevent dust from turning into slurry when the washing phase is
carried out. We recommend to pour the water into the central recovery
tank during the suction phase.
For better cleaning results it is recommended to have the escalators or moving
walkways move towards the operator.
1. Position the machine at the foot of the escalator (preferably on the bottom floor);
2. Position the machine on the first step making sure that the narrow side is lined up against
the edge of the step, and that the stabilising wheels are in the channels, regardless of the
position of the machine, which can either be on the right or the left hand side;
3. Use a wet vacuum cleaner.
4. Insert the suction hose into the appropriate opening in the cover (16) supplied;
5. Start up the external wet vacuum cleaner and the machine at the same time by lowering
the handle.
C
Figure 1.8
15

DUPLEX ESCALATOR BASE 350
6. Activate the escalator or moving walkway (preferably moving towards the operator);
7. Hold the machine firmly and make the escalator (or walkway) complete at least three full
rotations;
8. Raise the handle to stop machine operation;
9. Move the machine to the other side of the step and carry out the same procedure,
following the same sequence as above.
10. When the work is completed remove lid (C- figure “1.8” on page 15), adapted for the
attachment of a vacuum cleaner.
11. Empty the recovery tank and clean the machine in all its parts.
Figure 1.9
16

DUPLEX ESCALATOR BASE 350
2nd PHASE - WASHING
For better cleaning results it is recommended to have the escalators or moving
walkways move towards the operator.
1. Prepare a detergent solution consisting 95% of water and 5% of Detex (specific product to
clean escalators - see technical sheet).
2. Fill up the two tanks (T) with the special detergent solution.
IMPORTANT:
DETEX is a product expressly designed and developed for the cleaning
of escalators or moving walkways.
It does NOT damage surfaces, metal parts or components and rubber or
plastic components and the machine paintwork.
The use of products other than those specified will invalidate any
warranty and relieve the manufacturer from any liability deriving from
damage caused by the use of unsuitable products.
3. Position the machine on the first step;
4. Start up the machine lowering the handle;
5. Activate the escalator or moving walkway (preferably moving towards the operator).
6. Spread the detergent pressing the appropriate lever (Lfigure “1.2” on page 7) located
under the handle.
7. Make the escalator rotate several times until all dirt has been fully removed. Empty the
recovery tank (R) from time to time to prevent it from overflowing.
TRT
Figure 1.10
17

DUPLEX ESCALATOR BASE 350
IMPORTANT:
It is important for all three stabilising
guide wheels to be inserted into the
same channel or track, otherwise the
machine could move crossways and
work in an irregular manner.
Figure 1.11
Should the escalator or moving walkway be covered in
layers of dirt and muck due to wear, more frequent and long washing may be required.
Once the escalators' and moving walkways' optimal condition has been restored, routine
maintenance gets easier, quicker and cheaper.
The positioning of the Duplex Escalator Base on escalator steps or moving walkway
requires a certain dexterity and ability that the operator can acquire only after carrying
out various washing operations.
TIP:
To check whether the escalator/moving walkway has completed a full
rotation, and consequently a full washing session, apply a sticker to the
rubber handrail in the same direction of rotation. As the sticker re-
appears it means that the rotation has completed.
3rd PHASE - SOAKING (optional)
Very often, older escalators or walkways present greasy black deposits in the corners of the
steps which have built up over the years following the use of lubricants for the escalator
mechanisms that became impregnated with dust and dirt.
In this case the washing operation may be preceded by a preventive soaking phase.
We recommend that you use a standard pressure spray pump. Fill it with the same DETEX
product, either diluted or undiluted, and spray the product over the entire surface to be
treated evenly while the walkway is running.

1.10 GENERAL MAINTENANCE OF THE BASE 350
WARNING:
During cleaning and maintenance operations the machine must always
be disconnected from the mains.
WARNING:
Never use a pressure washer for cleaning operations.
The procedures described below must be carried out after each use of the machine.
CLEANING OF THE TANKS AND CONVEYOR BELTS
•Remove the three tanks and wash them under running water.
•Make sure that no foreign bodies are caught in the rubber valves located in the water tanks, to
prevent the dirt from obstructing the seal of the valves and causing the liquids to leak.
•Clean the drip channel with a thin wire or paper clip.
•Keep the recovery tank scraper clean at all times.
•Thoroughly clean the rubber conveyor belts and every part of the machine with a damp cloth.
•Use a brush to remove every residue of dirt from the corners, then wipe the machine dry
with a dry cloth.
•Lubricate the rubber conveyor belts with Duplex silicone spray.
CLEANING AND MAINTENANCE OF THE BRUSHES
DUPLEX brushes require little routine maintenance.
The high rotation speed during cleaning manages to centrifugate dirt and keep them efficient
at all times.
However, check their status and clean them, if necessary by soaking overnight in a mild
detergent
WARNING:
Remove the plug from the power socket before cleaning the brushes.
19

DUPLEX ESCALATOR BASE 350
ROUTINE MAINTENANCE
In addition to cleaning, it is necessary to perform the following operations periodically:
1. Remove the brushes from the machine (see following section);
2. Dip them in a container with cold or lukewarm water and let them soak for a few hours;
3. Stir and rinse the brushes well;
4. Re-fit the brushes in reversed position in relation to the one they had before (ref. point 1).
This is necessary as the bristles tend to bend when the brushes always rotate in the same
direction.
The mechanical parts of the DUPLEX ESCALATOR do not require any particular maintenance.
HOW TO REMOVE THE BRUSHES
•Unscrew the two screws anchoring the stainless steel casing using the supplied 6mm hex
key.
•Remove the brushes.
STORING THE MACHINE
• After use, store the machine in a covered and dry place, protected from atmospheric agents.
