2 Safety
2.1 Use in compliance with intended purpose
The machine is suitable as a sweeper for sweeping leaves,
waste and snow. With the sweepings container attached, the
sweeper can also be used for collecting leaves and litter.
Any use exceeding this is considered not in compliance with
the intended purpose. The manufacturer shall not be liable
for damage resulting from use not in compliance with the
intended purpose; the risk for this shall be in the sole
responsibility of the user.
Use in compliance with the intended purpose shall also include
compliance with the operation and maintenance provisions
specified by the manufacturer.
2.2 Possible misuse
It is particularly prohibited:
˗To sweep up any wires, cables or heavy stones (risk of injuries
and damage to the machine!);
˗To use a foot to push items under the sweeper (risk of injuries!)
˗To sweep any materials which may block the sweeping brushes
(machine damage!)
˗To charge the KM domus batteries with a non-original charger
(damage to battery);
˗To expose the battery in the machine to direct sunlight;
˗To pull the machine backwards unless it is absolutely necessary.

3 Design and function
3.1 Brief description
The sweeper may be used for sweeping and collecting (if a sweepings container is mounted) of loose dirt or snow. Die machine has a travel drive
and is driven by a petrol engine with electric starter. The sweeper brush function may be operated by means of a lever. The sweeper brushes can
be inclined in an angle of 45° in both directions. The KM domus 82V has a motor-battery connection allowing for sweeping at the push of a button.

3.3 Operating elements for all models
Lever for brush drive
The left-hand lever is used to operate the sweeper brush mechanism.
Operate the lever as follows:
Lever activated: Brush turns
Lever released (O): Deactivate brush
Lever for travel drive.
The right-hand lever is used to operate the sweeper drive mechanism.
Operate the lever as follows:
Lever pulled: Machine moves forward
Lever released (O): Deactivate travel drive
Brush height adjustment
The crank handle is used to set the height of the sweeper brushes by adjusting the support
wheel. The bristles of the brushes should only just touch the floor to be set optimally. An
excessively deep setting results in an overload of the drives and in inappropriate wear of the
brushes. An improperly adjusted brush will also result in a faster consumption of the battery
capacity.
Height adjustment:
Loosen the star grip nut, subsequently turn the screw to the requested position.
Turn right = sweeper brush is lifted
Turn to the left = lower the sweeping brush
Tighten the star grip nut in this position.
Electric motor 82V

If a warm or hot battery is inserted into the charger, the CHARGE LED lights up RED. Let
the battery cool down outside the charger for approx. 30 minutes.
d) FLASHING RED:
With a RED flashing LED, remove the battery from the charger and insert it again within 2
hours.
If the LED flashes RED again, the battery is defective and must be replaced.
If the pilot lamp indicates a normal charging process, the battery is o.k. For a check,
remove the battery after 2 hours and disconnect the charger for one minute. Insert the
battery and connect the charger to the power supply again. If a normal charging process
is indicated, the battery is o.k.
Charge battery system
Connect the battery charger to the power supply.
Push the battery into the charger. If the green LED is flashing, the battery is being charged. If
the LED lights up green, the battery is fully charged. The battery can now be removed from
the charger. Subsequently always disconnect the charger from the power supply.
Power button
This LED shows the capacity increase to 3300 revolutions. If additional capacity is required for
sweeping, the motor will automatically switch to the Turbo setting.
Note!
Increasing the speed will result in a faster consumption of the battery capacity and the battery
will have to be charged more often.
Always store the battery at
room temperature when it is
not used, in order to maintain
the battery capacity.
