Operation

DANGER
Long hours of using the appliance can
cause circulation problems on account of
vibrations.
It is not possible to specify a generally valid
operation time, since this depends on sev-
eral factors:
– Proneness to blood circulation deficien-
cies (frequently cold extremities, tin-
gling, numbness).
– Low ambient temperature. Wear warm
clothes to protect the affected body
parts.
– A firm grip impedes blood circulation.
– Continuous operation is worse than an
operation interrupted by pauses.
In case of regular, long-term operation of
the device and in case of repeated occur-
rence of the symptoms (e.g. tingling, numb-
ness in certain body parts) please consult a
physician.

 Pull seat adjustment lever outwards.
 Slide seat, release lever and lock in
place.
 Check that the seat is properly locked in
position by attempting to move it back-
wards and forwards.

Danger
Risk of injury! While reversing, ensure that
there is nobody in the way, ask them to
move if somebody is around.
ATTENTION
Risk of damage! Only use the direction
switch when the machine is standing still.
 Set the travel direction switch to "back-
wards".
 Press accelerator pedal down slowly.
Driving method
– The accelerator pedal can be used to
vary the driving speed infinitely.
– Avoid pressing the pedal suddenly as
this may damage the hydraulic system.
– In the event of power loss on inclined
surfaces, slightly reduce the pressure
on the accelerator pedal.
Brakes
 Release the accelerator pedal, the ma-
chine brakes automatically and stops.
Note: The braking effect can be supported
by pressing the brake pedal.
Driving over obstacles
Driving over fixed obstacles which are
70 mm (2.75 inch) high or less:
 Drive forwards slowly and carefully.
Driving over fixed obstacles which are
more than 70 mm (2.75 inch) high:
 Only drive over these obstacles using a
suitable ramp.

Sweeping mode

ATTENTION
Do not sweep up packing strips, wire or
similar objects as this may damage the
sweeping mechanism.
 For sweeping operation, set the engine
speed to 2550 rpm, see chapter "Multi-
function display | Setting the rpm".
Note
Settings of 1500 rpm are only intended
for transport travel and not for sweeping
operation (sweeping brush and side
brushes do not turn sufficiently).
Note: To achieve an optimum cleaning re-
sult, the driving speed should be adjusted
to take specific situations into account.
Note: During operation, the dust filter
should be shaken off and cleaned at regu-
lar intervals.
