1 General information
Congratulations! With the acquisition of this stair climbing system you have
a device that will quickly become a reliable and indispensable partner in
transporting physically disabled people.
With the C-max you are able to transport persons safely and effortlessly up-
and downstairs; even winding stairs are no problem for the C-max.
Driving on slopes is also possible. The safety brakes on both sides of the
C-max ensure your safety.
Naturally the C-max is also suitable to drive on level ground. The device is
lightweight, flexible and does not take up much space.
The c-max is capable of climbing stairs up to a step heigth of 21 cm. The mi-
nimum depth of the step’s surface must be 14 cm, regardless of the type of
stairs (regular straight stairs or winding stairs).
The necessary step width concerning straight stairs is the width of the c-max
plus an extra 10 cm for manoeuvring.
1.1 Instruction
This user’s manual will instruct you step by step about the safe and adequa-
te use of the C-max.
Operating the C-max takes a certain skill. In the interest of your safety only
trained personnel may use the C-max.
FPlease read this user’s manual carefully and particularly take note of
the safety instructions before you use the C-max for the first time.
1.2 Care and maintenance
One of the most important aspects concerning the maintenance of the C-max
is charging the sealed lead acid batteries. They are part of the battery pack
and must be charged every time after using the device.
Other than that your C-max does not need much care or maintenance. More
extensive instructions you find in chapter 8.
1.3 Warranty and liability
For damage that was caused by inadequate use disregarding this manual we
assume no liability whatsoever. (Please read chapter 9 for more detailed in-
formation concerning warranty and liability).

2 Description of the product
2.1 Adequate use
Please use the C-max exclusively for the transportation of physically disab-
led persons.
Said persons should be able to sit properly without help, otherwise you
should secure them with a safety belt. The latter is an accessory available at
AAT Alber Antriebstechnik GmbH.
In addition, the arms of the person to be transported should not protrude
over the arm rests during the transportation process.
FIn the interest of your safety you may not use the stair climbing devi-
ce C-max on escalators or moving belts!
FTransporting other kinds of loads is explicitly prohibited!
FOnly authorized operators may use the s-max. Therefore never leave
the s-max unattended.
FPlease do not use the c-max in the rain or generally in wet conditions
due to the following potential safety hazards, e.g. danger of slipping,
restricted braking effect etc.
