– Make sure that
the LH side brush (if fitted) is still in the raised position,
the RH side brush is still in the raised position,
the main brush is still in the raised position.
– Put the starting key into “Position 1”. The sweeper is
ready to operate.
!
Important information
– The drive mechanism is equipped with an electronic
overload fuse. Overload is indicated by a pilot lamp. In
the event engage the parking brake and release the drive
pedals(approx. 10 min.) until the drive components have
cooled down.
– For safety reasons the drive mechanism remains inac-
tive if a drive pedal is engaged before the keyswitch is
turned on.
Working with the sweeper
– Lower the main brush and, if required, the side
brush as well .
– Main brush roller and side brush switch themselves on
automatically.
– Switch the blower fan on in order to sweep without clouds
of dust forming.
– Release the parking brake by moving the lever
forwards
– Slowly depress the drive pedal, the speed can be
selected smoothly according to the setting.
Depress left pedal, machine moves backwards.
Depress right pedal, machine moves forwards.
Braking
– Release the drive pedal and the sweeper will brake
automatically.
Note: The braking effect can be increased by careful
operation of the drive pedal for the opposite direction
and/or by using the parking brake.
Going up slopes
– The sweeper can be driven in the fast gear (position )
for slopes up to a gradient of 15 %.
– For slopes of gradients between 15 % and 18 %, the
sweeper must be operated in low gear (position ).
Stopping the sweeper and switching off
– Release the drive pedal. The sweeper brakes automati-
cally and comes to a halt.
– Apply the parking brake .
– Make sure the main roller and side brush are raised so
that the bristles are not damaged. (Main brush roller,
side brush and blower fan switch off automatically).
– Turn the ignition key to “Position 0” and then remove it.
– Clean the sweeper inside and outside as required.
Recommendation: Clean interior with compressed air.
Wipe over the exterior with a damp cloth but do not use
an aggressive cleaning agent.
– Park sweeper in a protected place and stop it from rolling
away.
– Pull out battery plug connection.
– If the sweeper is shut down for a relatively long period,
charge the battery at approx. two-monthly intervals, see
in addition chapter “Maintenance”.
Cleaning the filter
Manual cleaning
While the sweeper is operating, the filter should be cleaned
approx. every 15–30 minutes (depending on amount of
dust).
– Switch off the blower fan. The electric filter cleaner is
operated automatically for approx. 10 seconds.
– Switch on the blower fan again.
Emptying the waste hopper
!
Important information
Injury hazard!
No person or animal should be allowed to remain in the area
traversed by the hopper while it is being emptied.
Danger of being crushed!
Do not reach into the shafts and linkage of the emptying
mechanism.
Do not stand under the raised hopper.
Risk of sweeper toppling over!
If the sweeper is standing on a slope with a gradient of more
than 5 %, it could topple over while the hopper is being
emptied. The hopper should therefore only be emptied when
the gradient at the location where the sweeper is standing
is less than 5 % for the direction in which it is facing.
– Stop the sweeper.
– Raise the main brush .
Note: Following steps can only be performed with the
sweeper set to two-handed operation.
– Raise the waste hopper, 1 + 2. +
When the hopper has reached the required height drive
backwards towards the discharge container.
