4.2 Intended use
The stair climber C120 is used to transport cargoes safely over stairs (upwards and downwards). In
doing so, both straight and spiral stairs can be travelled. Driving on slopes is possible, too.
Any other use is considered not in compliance with the intended use.
The C120 was developed to be operated by a single person. However, the use of a stair climber requires
a higher level of skill and experience than the use of a manual hand truck.
This user manual applies to the CargoMaster C120 V.

5.2 Inserting the battery pack
5.3 Unfolding and folding the toe plate
WARNING - Fix and lock battery pack so that it cannot become loose.
RISK of burns - Only remove the battery when the C120 has been switched o󰀨.
Installation.
Place the battery pack on
the locating pins on the drive
housing.
The battery pack locks in
place automatically.

5.7 Checking the safety brakes
DANGER - If the safety brakes only take e󰀨ect on one side or no e󰀨ect at all:
Do not use the C120. There is a risk of falling! Contact the manufacturer, the AAT eld service
or a certied partner.
DANGER - Do not support your foot on the housing. There is a risk of crushing!
WARNING - Check safety brakes prior to any run and without cargo.
The chassis has a safety
brake on each of both
sides.
Activate the safety brake on
both sides, respectively. To do
so, push the brake lever
upwards with the foot.
Move climbing leg to neutral
position (refer to section 5.6)
and tilt the C120 back.
TEST: Roll the C120 forward
and backward.
If it is not possible to roll the
C120 forward, the safety
brakes are active.
Pay attention to the note on
the housing.
