ƽ Danger
Danger of accident. If the machine does not
brake, then proceed as follows:

If the machine does not come to a halt
on a ramp with a gradient of 2% when
you release the drive pedal, then the
emergency-stop button may be
pressed for safety reasons only if the
mechanical functioning of the immobi-
lizing brake has been checked properly
before commissioning the machine.
Press the brake pedal if the machine
does not brake properly.
 Switch off the machine only after it
comes to a complete halt (on an even
surface) and call up the aftersales serv-
ice!
 Further, follow all warning instructions
for braking.

tilt.

The gradient perpendicular to the direc-
tion of travel should not exceed 15%.
