Check immobilizing brake

Danger
Danger of accident. The immobilizing brake
must always be checked first on an even
surface before starting the machine.
Take the seating position.
Set main switch to "1".
Select direction of travel.
Gently depress drive pedal.
The brake must get released and you must
be able to hear it (the control lamp for im-
mobilizing brake on the console switches
off). The machine must roll slightly on a
plane surface. When the pedal is released,
the brake falls in in an audible manner.
Switch off the machine and call the after-
sales service if the above-mentioned
events do not occur.
Brakes
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 pull
the battery plug in the sense of an
emergency-stop button for safety rea-
sons only if the mechanical functioning
of the immobilizing brake has been
checked properly before starting up the
machine.
Always pull the battery plug on plane
surfaces below 2% inclination.
Switch off the machine only after it comes
to a complete halt (on an even surface)
and call up the aftersales service!
– Further, follow all warning instructions
for braking.
Driving
Danger
Danger of tipping if gradient is too high.
The gradient in the direction of travel
should not exceed 10%.
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 surfaces.
Danger of tipping with excessive sideways tilt.
The gradient perpendicular to the direc-
tion of travel should not exceed 10%.
Sit on the seat and set main switch to
"1".

The drive direction can also be changed
during the drive. You can thus clean very
dirty surfaces by driving back and forth a
couple of times.

tomatically switches off after a certain peri-
od. A fault message is displayed on the
console.
The concerned unit gets switched off if the

wheel outwards.
The brake is unlocked and the appliance
can be pushed as long as the unlock lever
is kept in this position.

pulled, the appliance does not have any
braking effect.
Filling in detergents

ed detergents. With respect to different de-
tergents the operator bears the increased
