General safety instructions
iNOTE
If you have visual impairment, this user manual can be downloaded at:
www.aat-online.de/de/bda/s-max.
Read the user manual prior to start-up and observe the warning notices and safety instructions.
In the event of reading difculties, training contents must be further expanded upon verbally.
The user manual must be kept in a safe place after reading.
Contains some ammable materials. Keep the device away from sources of ignition.
s-max can interfere with highly sensitive electromagnetic elds of other electronic devices
(e.g. anti-theft devices).
Stability tests were performed under laboratory conditions. S-max can behave differently under real
conditions compared to laboratory tests.
Training may only be carried out by the manufacturer, the AAT eld staff or the qualied specialist shop.
CAUTION
External heat sources may cause the surface temperature to rise (e.g. sunlight)!
Do not touch the affected surfaces in this case to avoid burns!

Symbol Explanation
Handle with care
The packaging including the product must be handled with special care.
Protect from moisture
Protect the packaging including the product from overly high air humidity.
Cover during storage. Carefully cover with a tarpaulin, if necessary.
Caution fragile
Handle the packaging including the product carefully and never allow it to fall.
This way up
The packaging must be stored and transported in such a way that the arrows

or tilting the package, must be avoided.
2 Explanation of the symbols on the packaging
WARNING
To avoid being crushed, never reach into rotating/moving parts!
DANGER
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 maximum person weight, as this may lead to
defects or an overloading of the s-max!
Do not use in rain, wet, snow or ice as the restricted braking capacity may cause slipping!
Do not use on travellators or escalators as doing so may risk physical injury and/or material damage
as a result of crashing or the occupant falling out of the seat!
The operational capability of s-max can be inuenced by electromagnetic elds ((e.g. by mobile
phones, electric generators or high-voltage sources)!
Do not store near medical devices, for example with a life support function, and diagnostic devices, as
these may malfunction!

4.2 Indication and intended use
With the stair climber s-max you can transport one person with limited mobility safely and effortlessly
up and down stairs in their own wheelchair . You can conquer nearly all kinds of stairs and spiral stairs,
whether they are inside or outside. Driving on slopes is also possible.
The stair climber is developed to be operated by one person. This person must be trained and physically
and mentally capable of safely operating the s-max! They must have sufcient vision capability! Minors
below the age of 16 are not allowed to operate the s-max! Minors of at least 16 years are allowed to
operate the s-max, but only under supervision. Please bear in mind that the use of a stair climber can
entail a greater degree of risk and requires more skills than those required to operate a wheelchair.
The life expectancy of the s-max depends on the intensity of the application and is approx. 5 years
under normal use. This statement implies compliance with all prescribed maintenance and service
specications. The life expectancy can also be exceeded with careful handling. However, this life
expectancy can also be shortened due to overuse and improper handling.
This user manual is an all-purpose manual for the devices D1352 and D1601. The stair climbers only
differ in the technical dataand colour scheme. You can see which version you have by checking the
serial number. All chapters listed apply to both versions of the s-max.
4.3 Contraindication
The s-max may not be used if:
• the operator has not received training/instruction for the product!
• the operator is younger than 16 years old!
• the operator is a minor of at least 16 years, but there is no supervision!
• the operator is physically and mentally unable to safely use the s-max!
• more than one person needs to be transported at the same time!
• the person to be transported cannot sit independently!
• the operator does not have sufcient visual capacity!
• the braking effect is impaired due to rain, wet conditions, snow or ice!
• the required braking effect (on one side or both sides) is not guaranteed!
• escalators or travellators must be negotiated!
• medical devices, for example with a life support function, and diagnostic devices, are nearby!
• the intended use is contradicted!

4.4 Technical data
WARNING - Do not exceed the total permissible weight and the maximum person weight, as
this may lead to defects or an overloading of the s-max!

Classication according to
ISO 7176-28:2012 Type D (table 1 of annex A)
1) The climbing speed as well as the range with one charge of the batteries is reduced if the ComfortStep is activated. The range also depends on the weight
of the person seated.
2) Never use the stair climber to climb stairs with too little depth because it is no longer possible for the main wheels to touch the steps safely.
In the interest of progress we reserve the right for technical changes.

connected to the climbing unit!
WARNING - the climbing unit attachment may only be set by the manufacturer, the AAT eld
team or authorised specialist dealers!
A 9-pin sub-D coupling in the attachment establishes the electrical connection.
Connect the handle unitand
climbing unit.
»The attachment must be
aligned parallel to the
housing.
Secure connection with the
standpipe xing knob. Both
units must be connected
safely.
5.2 Battery pack
WARNING - The battery pack has to be locked safely, otherwise it may move involuntarily!
Assembly. Insert the battery
pack into the opening
provided for this purpose in
the climbing unit.
»The battery latch locks
automatically.
Disassembly. Loosen latch.
»Press down the release
button on the climbing unit,
then remove the battery
pack.

6.1 Adjusting the handles to the correct height
NOTE - Store s-max in a frost-free environment at least one hour prior to start-up to
avoid malfunctions.
NOTE - Wait a few seconds after turning on before pressing the UP/DOWN switch!
6 Start-up
WARNING - Always securely x the handle with a locking screw so the handle setting does not
change unexpectedly!
CAUTION - To avoid injury, beware of pinch points at the groove opening!
Turn the height adjustment
locking screw counter
clockwise and pull out the
handle at shoulder height.
Tighten the locking screw
clockwise.
6.2 Transverse adjustment handle
Turn the transverse
adjustment locking screw
anti-clockwise.
Move handle in the desired
direction.
Tighten the locking screw
clockwise.
The handle may hit the wall if the stairwells or spiral staircases are narrow. In these cases, adjust the
handle in a transverse direction.

6.4 Neutral position
Bring climber into the
neutral position by pressing
the UP/DOWN switch.
»If single step mode
(see Chapter 6.6)
is activated, climber
will stop automatically in the
neutral position!
Correct. Wrong!
Insert safety chip for the
engine immobiliser.
»Safety chip must latch!
Turn on s-max by
pressing the ON/OFF
switch .
6.3 Turning on the device

6.5 Checking the safety brakes
DANGER - Do not use the s-max if the required braking effect (on one side or both sides) is not
guaranteed because a reduced braking effect can lead to falling down the stairs. Contact the
manufacturer or your authorised dealer!
WARNING - Check safety brakes without an occupant!
There are safety brakes
located on both sides of the
climbing unit. Activate them
for checking the effect.
» Check the safety brakes
before each use.
Pull in the climbers to their
upmost position and tilt s-max
backwards.
Test: s-max cannot
be pushed forward,
only backwards =
safety brakes activated.
i
Manufacturer’s
recommendation:
Put your foot on the
housing and tilt the
s-max towards you. See
detailed description in
Chapter 8.3.
Single step mode
Activate / deactivate.
LED glows = single step
mode is activated!
Should you choose to
turn off the single step
mode you can do so by
pressing the appropriate
button.
» LED does not glow = single
step mode is deactivated!
i
Manufacturer’s
recommendation:
Only deactivate the
single step mode,
if the operator is able
to use the s-max safely.
DANGER - If the single step mode is deactivated, make sure to operate the s-max correctly and
safely! Otherwise it can lead to falling down the stairs!
6.6 Single step mode

process.
Should you choose to turn
off the ComfortStep you
can do so by pressing the
appropriate button.
» LED does not glow =
ComfortStep is deactivated!
Manufacturer’s
information:
Every time you
turn on the device, the
last used setting will be
reproduced.
