on an ascent of above 2%, then the key
switch must not be set to 0. The appli-
ance must continue to be operated until
a horizontal plane is achieved with it.
 When a horizontal plane has been
achieved, the appliance must be shut
down and aftersales service needs to

 Further, follow all warning instructions
for braking.
DANGER
Danger of tipping if gradient is too high.
 The gradient in the direction of travel
should not exceed 8%.
Drive only lengthwise on uphill and
downhill gradients, do not turn.
Danger of tipping when driving round
bends at high speed.
Danger of slipping on wet floors.
 Drive slowly when cornering.
Danger of tipping on unstable ground.
 Only use the machine on sound surfac-
es.
Danger of tipping with excessive sideways
tilt.
