houses, car parks and pedestrian pre-
cincts. Any use beyond this is regarded
as improper use. The manufacturer is
not considered liable for any damage
resulting from improper use; the user is
solely responsible for all the risks. The
sweeping vehicle must not be used to
clear up toxic, inflammable or other
substances which represent a potential
health hazard. Intended use also inclu-
des maintaining and observing the ope-
rating, maintenance and repair
conditions prescribed by the manufac-
turer.
The Hako-Jonas 1500 may only be
operated, serviced and repaired by per-
sonnel who are familiar with the work in-
volved and are aware of the risks.
Based on the conception, design and
construction of the model introduced
onto the market by us, the machine

Notes on warranty
The terms defined in the purchase
agreement apply. Claims for compen-
sation related to damage are excluded
from the terms of warranty when the da-
mage is the result of failure to observe
regulations concerning service and
maintenance. Maintenance work must
be performed by authorized Hako ser-
vice centers and confirmed in the
“Maintenance Report” which serves as
a warranty logbook.
The following are excluded from the
terms of warranty: wear and tear
through overuse, defective fuses, im-
proper handling and use or unauthori-
zed modifications. Claims under the
terms of warranty are also annulled
when damage occurs to the vehicle re-
sulting from the use of parts or accesso-
ries not explicitly approved by us or
from failure to observe maintenance re-
gulations.
Handover of the machine
Inspect the vehicle immediately on deli-
very for signs of transport damage. Re-
placement will be made when confir-
mation is provided immediately by the
freight carrier with regard to the dama-
ge and the damage report is sent to our
authorized sales partner together with
the consignment note.
Conditions for approval
The Hako-Jonas 1500 is an automotive
machine within the terms defined in the
Road Traffic Licensing Regulations
(FZV §2, previously StVZO §18).
On request, the manufacturing plant
can enclose a report with which to ac-
quire the vehicle type approval. This re-
port is used by the local vehicle
registration office to produce a valid ve-
hicle registration license (Vehicle Regi-
stration Certificate, Part 1).
An official license number is not neces-
sary. A general inspection in accor-
dance with § 29 StVZO (road traffic
licensing regulation) is not required eit-
her because the vehicle is designed for
a top speed under 20 kph. In accor-
dance with the StVZO, the vehicle must
carry a first-aid kit, warning triangle and
the vehicle registration license when
used on public roads, paths and pede-
strian precincts.
If any attachments or conversions are
made on the Hako-Jonas 1500, which
affect the equipment described in the
vehicle registration license and are not
mentioned in the vehicle registration li-
cense, the license becomes invalid. To
acquire a new vehicle registration licen-
se, the vehicle must be presented to an
officially accepted expert to produce a
new report. The report becomes the of-
ficial vehicle registration license when
the vehicle registration office applies
the applicable stamp.
Driving license
In accordance with the provisions on
driving licenses, a person who intends
to drive a motor vehicle constructed
with a top speed in excess of 6 kph on
public roads, paths and pedestrian pre-
cincts, must be in possession of a valid
driving license. Drivers of the Hako-Jo-
nas 1500 require a driving license for
automotive agricultural machines up to
25 kph (Class L or higher).
