To reduce the risk of fire, electric shock, or
injury:
– Do not leave appliance when plugged in.
Unplug from outlet when not in use and
before servicing.
– TO REDUCE THE RISK OF ELECTRIC
SHOCK-USE INDOORS ONLY
– Do not allow to be used as a toy. Close
attention is necessary when used by or
near children.
– Use only as discribed in this manual. Use
only manufacturer`s recommended
attachments.
– Do not use with damaged cord or plug. If
appliance is not working as it should, has
been dropped, damaged, left outdoors,
or dropprd into water, return it to a
service center.
– Do not pull or carry by cord, use cord as
a handle, close a door on cord, or pull
cord around sharp edges or corners. Do
not run appliance over cord. Keep cord
away from heated surfaces.
– Do not unplug by pulling on cord. To
unplug, grasp the plug, not the cord.
– Do not handle plug or appliance with wet
hands.
– Do not put any object into openings. Do
not use with any opening blocked; keep
free of dust, lint, hair, and anything that
may reduce air flow.
– Keep hair, loose clothing, fingers, and all
parts of body away from openings and
moving parts.
– Turn off all controls before unplugging.
– Use extra care when cleaning on stairs.
– Do not use to pick up flammable or
combustible liquids, such as gasoline, or
use in areas where they may be present.
– Connect to a properly grounded outlet
only. See Grounding Instruction.
This appliance must be grounded. If it
should malfunction or breakdown, ground-
ing provides a path of least resistance for
electric current to reduce the risk of electric
shock. This appliance is equipped with a
cord having an equipment-grounding con-
ductor and a grounding plug. The plug must
be inserted into an appropriate outlet that is
properly installed and grounded in accor-
dance with all local codes and ordinances.
Improper connection of the equipment
grounding conductor can result in a risk of
electric shock. Check with a qualified electri-
cian or service person if you are in doubt as
to whether the outlet is properly grounded.
Do not modify the plug provided with the ap-
pliance-if it will not fit the outlet, have a prop-
er outlet installed by a qualified electrician.
This appliance is for use on a nominal 120-
volt circuit and has a grounding attachment
plug that looks like the plug illustrated in
sketchpicture A. Make sure that the
appliance is connected to an outlet having
the same configuration as the plug. No
adaptor should be used with this appliance.

For operator:
Please ensure that all users of the machine
have read and understood the contents of
this Operating Instructions Manual and are
familiar with the local regulations about work
safety. The users must have been techni-
cally trained to use this appliance.
For users:
Before using the appliance for the first time,
read and observe these operating instruc-
tions and the accompanying brochure: Safe-
ty information for brush cleaning units and
spray-extraction units, No. 5.956-251.
Safety devices serve to protect the user and
must not be rendered inoperational or their
functions bypassed.
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, deter-
gent fluid (from the fresh water tank) is ap-
plied 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 work-
ing step, the dirty detergent is sucked into
the dirt water tank of the machine via the in-
take brushes.
Use this appliance only as directed in these
operating instructions.
– The appliance may only be used to clean
the stepping areas of travellators/ esca-
lators.
– The running or movement direction of
the unit to be cleaned must be adjusted
in such a way that the travellator/ escala-
tor moves away from the machine.
– To clean the escalator, place the ma-
chine only at the lower end of the escala-
tor.
– The appliance may only be equipped
with original accessories and spare
parts.
– The appliance may only be used by per-
sons whose weight is more than 65 kg.

en blocks used for stopping the wheels.
ÎFour indicated floor boards of the pallet
are fastened with screws. Unscrew
these boards.
ÎPlace the boards on the edge of the pal-
let. Place the boards in such a way that
they lie in front of the four wheels of the
machine. Fasten the boards with screws.
ÎSlowly push the machine down from the
ramp.
Note
At the time of manufacturing the appliance,
it has already been flused using an anti-frost
agent. Before starting the machine for the
first time, you need to first remove the anti-
frost agent.
ÎFill in 10 litres of fresh water in the fresh
water reservoir.
ÎPress the foot pedal.
ÎSet the machine switch to basic clean-
ing.
ÎKeep the machine running until the pres-
sure on the manometer falls.
Danger
Risk of injury! The appliance can get stuck
and be dragged away by the travellator/ es-
calator. Before starting cleaning, check the
stepping areas and the ridge profile to see
that there are no deformations or any ob-
jects stuck therein. To be on the safer side,
make sure that you know where the emer-
gency switch-off button of the travellator/ es-
calator is located.
ÎCordon off the travellator/ escalator as
long as cleaning operations are on and
the stepping areas are still wet.
ÎSwitch on the travellator/ escalator.
ÎEnsure that the running direction of the
travellator/ escalator is away from the
machine.
ÎCheck whether the combs and the guide
rails of the machine match the make of
the travellator/ escalator. Replace the
combs and the guide rails, if required.

Danger
Risk of injury!
–The body weight of the user must be at
least 65 kg.
–Press the foot lever with only one foot.
The other foot must be placed firmly on
the ground.
–Hold the pushing handle firmly with at
least one hand.
–Loose fitting clothes and jewellery can
get entangled in the moving parts of the
travellator/ escalator. Hence, remove
jewellery and wear clothes fitting well on
the body and safety shoes.
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/ escalators
(normally, at short regular intervals). At this
setting, the appliance works with reduced
quantity of water. The water pump works
with regular strokes.
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 manual-
ly.
– 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 re-
move detergent residues.
