CAUTION
External heat sources may cause the surface temperature to rise (e.g. sunlight)!
Do not touch the a󰀨ected surfaces in this case to avoid burns!
WARNING
Never reach into rotating/moving parts to avoid crushing.
DANGER
The s-max must not be operated in the case of severe visual impairment and/or blindness!
Do not exceed the total permissible weight and the max. person weight, as this may lead to defects or
overload the s-max!
Do not use in rain, wet conditions, snow or black ice to avoid slipping due to the reduced braking
e󰀨ect!
Do not use on escalators or travellators to avoid injuries from falling, the occupant tipping out and
damage to property!
The operability of the s-max may be inuenced by electromagnetic elds (e.g. by mobile phones,

4.3 Intended purpose
4.4 Intended patient population
The stair climbers are guided manually and are operated by an operator.
They make it possible to transport a single person with reduced mobility safely over stairs, upwards and
downwards. The products have been designed for indoor and outdoor use, and moving on spiral stairs
and slopes is possible, too.
The intended patient population includes all persons who are able to sit independently and have a
maximum body weight corresponding to the technical specication of the respective model and variant
(max. 115 kg for the s-max D1352).

4.5 Medical requirements and indication
4.6 Contraindications and restrictions
4.7 User group
The patients must be able to sit independently. Secure persons who cannot sit upright unaided with belts
(refer to accessories) to prevent the occupant from falling out!
The manually guided stair climber assists the accompanying person while transporting the patient in the
wheelchair over stairs or slopes, upwards and downwards. The use of the stair climber is intended for
patients who are not able to move by themselves and accompanying persons who do not have su󰀩cient
physical endurance and strength to move the patient in the wheelchair over stairs or slopes. The s-max
is used to transport patients with their own wheelchair.
The stair climbers must not be used if:
• the operator has obtained no training/instruction for the product!
• the operator is below the age of 16!
• there is no supervision for minors of at least 16 years of age!
• the operator is not physically and mentally able to operate the stair climber safely!
• more than one person shall be transported simultaneously!
• the person to be transported cannot sit upright unaided!
• the operator does not have adequate eyesight!
• the braking e󰀨ect is reduced due to rain, wet conditions, snow or black ice!
• the one-side and/or two-side braking e󰀨ect of stair climber does not set in!
• escalators or travelators shall be overcome!
• medical devices with e.g. a life support function, and diagnostic devices are in the proximity!
• it is not used according to the intended use!
The stair climbers are intended for the use by:
medical sta󰀨,
• healthcare professionals,
• driving services, and
• laymen.
Users are trained in the use of the device by means of a training course.

Adhesive label with serial number On the left of the housing and rear side of the user manual
IP protection class IPX4
Classication according to ISO 7176-28:2012 Type D (according to Annex A, Table 1)
1) With activated ComfortStep, the climbing speed and the range are reduced. The range also depends on the weight of the occupant.
2) Any steps of a smaller depth may not be travelled as in this case it is no longer possible for the wheel to be set down safely.
3) The person weight on the type plate and in the technical data were calculated using an assumed wheelchair weight of 20 kg.
4) Observe the maximum load according to the wheelchair manufacturer's information.
5) At temperatures below 0 °C the performance of the battery pack will decrease; therefore we recommend a storage temperature of at least 0 °C.

5.1 Handle unit
WARNING - The handle unit must be securely xed with the locking screw so that it is safely
joined to the climbing unit!
WARNING - The climbing unit mount may only be adjusted by the manufacturer, the AAT eld
service or an authorised specialist dealer!
A 9-pin sub-D coupling in the receptacle provides the electrical connection.
Connect the handle unit and
the climbing unit to each
other.
»The mount must be aligned
parallel to the housing.
Secure the connection with
the locking knob for the
stanchion tube.
Both units must have been
securely joined.
5.2 Battery pack
WARNING - The battery pack must be xed and locked to prevent immediate detachment!
Assembly. Insert the battery
pack into the opening
provided in the climbing unit.
»The battery locking device
is activated automatically.
Disassembly. Release the
locking device.
»Press the release button on
the climbing unit downwards,
then pull out the battery
pack.

6.1 Adjusting the handles to the correct height
NOTE - To avoid malfunctions or defects, store the s-max in a frost-free environment for at least
one hour prior to start-up.
NOTE - Press UP/DOWN switch only a few seconds after switching on!
6 Starting up
WARNING - The handle must have been securely xed with the locking screw so that the
handle adjustment does not change directly!
CAUTION - Pay attention to the pinch point at the groove opening to avoid injuries!
Turn the locking screw
for height adjustment
counterclockwise and pull out
the handle to shoulder height.
Tighten the locking screw
clockwise.
6.2 Transverse adjustment of handle
Turn the locking screw
for transverse adjustment
counterclockwise.
Move the handle in the
desired direction.
Tighten the locking screw
clockwise.
In the case of very narrow staircases or spiral stairs, the handle might hit the wall. In these cases, adjust
the handle in the transverse direction.

6.4 Neutral position
Move the climbing leg to
neutral position by keeping
the UP/DOWN switch
pressed.
»If the single-step mode
(refer to chapter 6.6)
has been activated,
the climbing leg
is automatically stopped in
neutral position!
Correct. Incorrect!
Insert the safety chip for the
immobiliser.
»The safety chip must snap
in!
Switch the s-max on via the
ON/OFF switch .
6.3 Switching on the device

6.5 Checking the safety brakes
DANGER - If there is only a one-sided braking e󰀨 ect or no braking e󰀨 ect at all, do not use the
s-max, to avoid falling from the stairs. Notify the manufacturer, the AAT  eld service, or the
authorised specialist dealer!
WARNING - Check safety brakes without occupant!
There are safety brakes
located on both sides of the
climbing unit. Activate them
for testing.
»Test the safety brakes
before every journey.
Retract the climbing leg
completely and tilt the s-max
backwards.
Test: the s-max cannot
be rolled forwards,
but only backwards =
safety brakes active.
i
Recommendation by
the manufacturer:
as an aid, support foot
on the drive housing to
tilt the s-max backwards.
For a detailed procedure,
refer to chapter 8.3.
Single-step mode
Deactivate / Activate.
LED is lit = single-step mode
activated!
If you do not need the
single-step mode, you can
switch it o󰀨 manually on the
membrane keypad.
» LED is not lit = single-step
mode deactivated!
i
Manufacturer’s
recommendation:
Only deactivate the
single-step mode,
if the operator
is able to handle the
s-max safely.
DANGER - With the single-step mode deactivated, it is mandatory to ensure correct operation,
otherwise the s-max may slip!
6.6 Single-step mode

6.7 ComfortStep
Deactivate / Activate.
»LED is lit = ComfortStep
activated!
»This ensures a gentle and
thus more comfortable
climbing procedure.
If you do not need
ComfortStep, you can
switch it o󰀨 manually on the
membrane keypad.
» LED is not lit =
ComfortStep deactivated!
Manufacturer’s
information:
Each time the device is
switched on again, the
memory function plays
back the last setting
used.
i
NOTE - If an adjustment of the step height is to be made, please contact the AAT  eld service
or an authorised specialist dealer!
