6.5 Checking the safety brakes
DANGER - If there is only a one-sided braking eff ect or no braking eff ect, do not use the CR23,
to avoid falling from the stairs. Notify the manufacturer, the AAT fi eld service, or the authorised
specialist dealer!
WARNING - Check safety brakes without occupant!
There are safety brakes on
both sides of the chassis.
» Test the safety brakes be-
fore every journey.
Retract the climbing leg
completely and tilt the CR23
backwards.
Test: The CR23 cannot be
rolled forwards, but only
backwards = safety brakes
active.
6.6 Single-step mode
Single-step mode
Deactivate / Activate.
LED is lit = single-step mode
activated!
If you do not need the sin-
gle-step mode, you can
switch it off manually on the
membrane keypad.
» LED is not lit = single-step
mode deactivated!
i
Manufacturer’s recom-
mendation:
Only deactivate the sin-
gle step mode, if the op-
erator is able to handle
the CR23 safely.
DANGER - With the single-step mode deactivated, it is essential to ensure correct operation,
otherwise the CR23 may slip!
i
Recommendation by
the manufacturer:
As an aid, support your
foot on the drive hous-
ing to tilt the CR23 back-
wards. For the detailed
procedure, refer to chap-
ter 7.3.
