Intended use
The Hako-Jonas 1900 is a sweeping
vehicle conceived exclusively for
sweeping up dry and wet refuse from
areas such as production plants, ware-
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
risk to health. Intended use also inclu-
des maintaining and observing the ope-
rating, maintenance and repair
conditions prescribed by the manufac-
turer.
The Hako-Jonas 1900 may only be
operated, serviced and repaired by per-
sonnel who are familiar with the work in-
volved and are aware of the risks. The
applicable accident prevention laws
must be observed and any generally
accepted health and safety directives
must be maintained. The manufacturer
is not deemed liable for any damage re-
sulting from unauthorized modifications
to the vehicle.

Conditions for approval
The Hako-Jonas 1900 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 accordan-
ce 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 accordan-
ce 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 1900 1900 V/
D which affect the equipment described
in the vehicle registration license and
are not mentioned in the vehicle regi-
stration license, the license becomes
invalid. To acquire a new vehicle regi-
stration license, the vehicle must be
presented to an officially accepted ex-
pert to produce a new report. The report
becomes the official vehicle registration
license when the vehicle registration of-
fice 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 1900 require a Class L driving li-
cense (motor vehicles up to 25 kph).

2.1 Instruction
Instruction is required before first ope-
ration. First instruction into handling of
the machine must be held by a qualified
person sent by your local PowerBoss
contract dealer. Your PowerBoss dea-
ler will be informed by the manufacturer
upon delivery of the vehicle and will
contact you to make a date for instruc-
tion.
2.2 Prior to starting up
Carry out the following checks before
starting the vehicle:
1. Check the parking space for signs of
leaks. Hoses, lines and tanks must
show no signs of leaks or damage.
2. Check the fuel supply, refill if neces-
sary; refer to Chapter Maintenance.
3. Check the engine oil level, refer to
Chapter Maintenance.
4. Check the hydraulic oil level, refer to
Chapter Maintenance.
The hydraulic system cannot bring
its full performance at low tempera-
tures!
5. Check the seat adjustment, refer to
Chapter Operation.
6. Check the steering wheel adjust-
ment, refer to Chapter Operation.
2.3 Starting the vehicle
Before starting the vehicle, pay
attention to the operating infor-
mation in Chapter "Safety In-
formation".
The following operating elements must
be actuated in succession to start the
vehicle:
For safety reasons, the driver's
seat is equipped with a seat
contact switch. The function of
the seat contact switch must
not be bypassed.
1. All control levers and switches
(sweepings container, rotary brush,
accelerator, etc.) must be in their
neutral position. The zero setting is
monitored electronically. A deflection
of the pedal from this position pre-
vents the engine being started.
2. The vehicle's parking brake must be
applied.
3. Set the engine speed switch to idling
speed.
4. Turn the ignition key clockwise a litt-
le. The preheating control lamp lights
up. Continue preheating until the
control lamp goes out.
5. Turn the ignition key further to start
the engine. The load control lamp
goes out. The fuel quantity, engine
oil pressure, engine temperature and
battery charge indicators appear.
6. Set the engine speed switch to its id-
ling position and allow the engine to
warm up a little.
The Hako-Jonas 1900 may
only be used in ambient tem-
peratures up to 40°C.
It should not be started at tem-
peratures <-15°C. At extremely
low temperatures, the hydrau-
lic system requires a few minu-
tes until it reaches operating
temperature and can provide
its full power output. Full loads
should only be applied to the
units on reaching operating
temperature.
If the start procedure must be
repeated or the engine stalls, it
can only be restarted after the
ignition has been switched off.
A restart blocking system in the
ignition lock prevents restar-
ting when the engine is run-

using a propellant gas system,
refer to the LPG Operating Ma-
nual.
2.4 Putting into operation
Proceed as follows to prepare the ve-
hicle for operation:
1. Check the vehicle, refer to Section
2.2 - Prior to operation.
2. Start the vehicle, refer to Section 2.3.
3. Lower the rotary brush and side
brushes.
4. Switch on the side brush drive.
5. Switch on the suction turbine (only
for dry waste).
6. Release the parking brake to its end
position.
7. Slowly press the accelerator until the
required driving speed is reached.
8. Activate the agitating device at regu-
lar intervals to clean the filter.
9. Check the refuse in the sweepings
container regularly; if necessary, op-
timize the sweepings container volu-
me by implementing the RTR system
or emptying the sweepings contai-
ner.
When the function of the side
brushes and suction turbine
remain on, you can use the ro-
tary brush control lever to
switch all the sweeping
functions on and off.
2.4.1 Optimum use of the
sweepings container (RTR sy-
stem)
The RTR system serves to compress
the refuse in the sweepings container,
thus increasing the fill volume.
When the RTR system is activated, the
sweepings container automatically
stops in front of the opening point of the
discharge flap. The indicator is above
the control lamp on the operating panel.
The discharge flap remains closed and
the refuse drops from the loading sec-
tion to the area of the discharge flap.
1. Set the engine speed to idling speed.
2. Switch the RTR system on.
3. Raise the sweepings container; to do
this press and hold the safety switch
and simultaneously move the
sweepings container control lever to
the rear.
The sweepings container can
only be pivoted when the
sweepings container has been
lifted past a minimum height to
prevent a collision between the
sweepings container and
chassis. The sweepings con-
tainer is locked against turning
when below this min. height.
4. Pivot the sweepings container; to do
this press and hold the safety switch
and simultaneously move the
sweepings container control lever to
the right.
5. The refuse is distributed optimally in
the sweepings container.
6. Pivot the sweepings container back
again; to do this press and hold the
safety switch and simultaneously
move the sweepings container con-
trol lever to the left.
7. Lower the sweepings container; to
do this press and hold the safety
switch and simultaneously move the
sweepings container control lever to
the rear.

First Operation
The container can only be lo-
wered fully when it is horizon-
tal. If the container is slightly
turned when lowered, it auto-
matically stops before colliding
with the chassis. In such ca-
ses, the container must be rai-
sed a little again and turned so
that it is properly horizontal.
2.4.2 Emptying the sweepings
container
1. Drive the Hako-Jonas 1900 to the
waste disposal depot.
2. Stop the Hako-Jonas 1900 with a
safety clearance in front of the refuse
container.
3. Set the engine speed switch to idling
speed.
4. Clean the filter system; set the
switch for the agitating device to ON.
5. Raise the sweepings container; to do
this press and hold the safety switch
and simultaneously move the
sweepings container control lever to
the rear.
6. The sweepings container must ex-
ceed the minimum height for the
container emptying process.
7. Drive the Hako-Jonas 1900 forwards
until the sweepings container is over
the refuse disposal container.
8. Pivot the sweepings container to its
emptying position; to do this press
and hold the safety switch and simul-
taneously move the sweepings con-
tainer control lever to the right.
9. Empty the sweepings container
completely.
10.Pivot the sweepings container back
again; to do this press and hold the
safety switch and simultaneously
move the sweepings container con-
trol lever to the left.
11.Reverse the Hako-Jonas 1900 and
stop it in front of the container obser-
ving the necessary safety clearance.
12.Lower the sweepings container; to
do this press and hold the safety
switch and simultaneously move the
sweepings container control lever to
the front.
Driving the vehicle with the
sweepings container raised re-
duces the vehicle's stability.
Therefore, only raise the
sweepings container immedia-
tely prior to emptying it. Before
raising the sweepings contai-
ner, the operator must have
ensured that there are no per-
sons or items in front of or be-
side the vehicle. Only raise the
sweepings container when the
vehicle is on a horizontal sur-
face.
The vehicle may only be driven
slowly when the sweepings
container is raised.
It is forbidden for anyone to
move into the danger area.
Risk of crushing and shearing!
Before raising or lowering the
sweepings container, ensure
that there is a sufficient safety
clearance.
The sweepings container may
only be filled to the maximum
permitted filling weight. Over-
loading causes a reduction in
vehicle stability.
The sweepings container must
be cleaned at regular intervals.
The sweepings container mo-
vements are monitored. The
sweepings container comes to
an automatic stop if there is a

20
First Operation
risk of collision with other ma-
chine parts which could result
in damage. In such cases, the
sweepings container must be
moved in the opposite direction
to reactivate the function.
2.5 Stopping and switching off
the vehicle
1. Slowly move the accelerator to its
zero setting to decelerate the vehicle
until it stops.
2. Pull the parking brake to its end po-
sition.
3. Raise the rotary brush and side brus-
hes.
4. Switch off the engine.
The Hako-Jonas 1900 can be

celerator in the opposite direc-
tion or applying the service
brake.
Remove the ignition key when
getting off the vehicle to pre-
vent unauthorized use.
2.6 After completing work
Drive to a suitable servicing location
and clean the vehicle.
It is not permitted to clean the
vehicle with a pressure washer
or steam blaster.
