Preface
READ THESE OPERATING INSTRUCTIONS CAREFULLY to familiarise yourself
with the correct way to operate and service your machine, and to
prevent personal injury or damage to the machine.
These operating instructions and the adhesive safety signs on your
machine can also be obtained in other languages
(your dealer can order these for you).
THESE OPERATING INSTRUCTIONS ARE a permanent part of your machine and
should be handed over to the new owner if the machine is sold.
MEASUREMENTS in these operating instructions are given in the metric
system. Only use suitable parts and screws. Different wrenches are
required for metric and inch screws.
THE DESIGNATIONS “RIGHT” AND “LEFT” refer to the forward driving
direction of the mounted equipment.
ENTER THE PRODUCT IDENTIFICATION NUMBERS in the appropriate “Technical
data” or “Product - Identification Number” sections. Please ensure
that all figures are accurately entered. These numbers can be of
invaluable assistance for tracing the machine should it be stolen.
Your dealer also needs these numbers when you order spare parts. We
recommend that you additionally file these identification numbers in
a secure place away from the machine.
BEFORE DELIVERY OF THIS MACHINE, your dealer performed a pre-delivery
inspection to ensure optimal performance.
THIS DEVICE DESIGNED EXCLUSIVELY for commercial use and regular
application in the maintenance of greens and parks for the wind
generation through air without particles carried in the air stream
(“SPECIFIED USE“).
Usage for any other purpose beyond this is considered as contrary to
the intended use. The manufacturer accepts no liability for damage
or injury resulting from this improper use. These risks are borne
solely by the user. Compliance with and strict adherence to the
operating, maintenance and repair conditions as specified by the
manufacturer also form essential elements of the intended usage.
FORESEEABLE INCORRECT USE/MISUSE. It is not permitted to use the
attached device to transport persons or things.
THIS MACHINE MUST ONLY BE operated, maintained and repaired by persons
familiar with all its particular characteristics and acquainted with
the relevant safety regulations. The relevant accident prevention
regulations, all other generally recognised safety-related,
occupational medicine and road traffic regulations must be adhered
to. Any modifications carried out to this machine without the
express approval of the manufacturer excludes the manufacturer of
all liability for any resulting damage.

1.0. Safety
Use safety lights and devices
Prevent collisions between other
road users, slow moving tractors
with attachments or towed
equipment, and self-propelled
machines on public roads.
Frequently check for traffic
from the rear, especially in
turns, and use hand signals or
turn signal lights.
Use headlights, flashing warning
lights, and turn signals day and
night. Follow local regulations
for equipment lighting and
marking. Keep lighting and
marking visible and in good
working order. Replace or repair
lighting and marking that has

using a torch near pressurized
fluid lines or other flammable
materials. Pressurized lines can
be accidentally cut when heat goes
beyond the immediate flamme
area.

injected into the skin must be
surgically removed within a few
hours or gangrene may
result.Doctors unfamiliar with
this type of injury should
reference a knowledgeable
medical source.

2.0. Mounting
2.1. GENERAL
WARNING:
Mount the machine only with
the engine shut off and the
PTO switched off. The
signboards applied on the
machine show important
warnings and directions for
safe operations.
Observe these signs for your
safety.
Check the engine speed and
sense of rotation (stickers on
the machine) against the
specifications of your
tractor. The stickers specify,
to which engine speed and sense
of rotation the machine has
been set.
2.2. Tractor attachments
As a standard, the blower can
be mounted on a three-point
linkage cat. 1.
1. Attach bottom connecting rod
to both pins (A) and secure.
2. Attach top connecting rod
with pin (B) to the bore
matching the tractor type
and secure.
3. The adjustment is made with
the top connecting rod.
During mounting take care that
the blower stands parallel to
the soil.

2.3. Extended attachment
The attachment can be extended
by 60 mm.
Remove front protective
cover
Release securing screws in
hole row A and B
Secure the mount (D) in
hole row B and C
The mount for the top
connecting rod can also be
extended 60 mm.
Release securing screws in
hole row A and B.
Secure the top connecting
rod frame (E) in hole row
B and C
When the conversion is
complete, reinstall the front
protective cover.
2.4. Supports
The supports must be inserted in
the holder from above, as shown
in Fig. 4603.44. Attach supports
in the middle bore and secure
with spring cotters.

2.0. Mounting
2.5. Drive shaft adjustment
To adjust the length, hold the
half shafts next to each other
in the shortest working position
and mark them.
Shorten inner and outer
protective tubes equally.
Shorten inner and outer sliding
profiles by the same length as
the protective tubes.
Round off all sharp edges and
remove burrs. Grease sliding
profiles.

2.0. Mounting
2.6. Cardan shaft
The length of the cardan shaft is
to be checked in the working
position and in removed position.
If the cardan shaft is too long,
it must be shortened according to
the description below.
When working with lifted-off
blower, pay attention to the
angle of the cardan shaft. If the
angle exceeds approx. 20°, the
standard cardan shaft must be
exchanged for a wide-angled
cardan shaft of the same size.
The protection for the cardan
shaft has to be fixed with the
safety chain.
2.7. Hydraulic connections
For hydraulic swiveling of the
blow-out nozzle an independently
switchable, double-acting
hydraulic valve is necessary.
The hydraulic hoses of the
swivel mechanism are equipped
with connectors of size 3.
Before coupling, the connectors
and sockets have to be cleaned
thoroughly in order to prevent
impurities from getting into the
hydraulic circuit. The hoses have
to be laid in such a way, that
no shear and abrasion spots can
occur. If necessary, the hoses
have to be fixed at the
appropriate places.
When the blower is dismounted,
the hydraulic connectors should
be protected from damages and
soiling by attaching the dust
guard caps.
