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. NO materials may be
poured into the blower via the intake grille.
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.

SCHUTZKLEIDUNG TRAGEN
Wear close fitting clothing and
safety equipment appropriate to
the job.
Prolonged exposure to loud
noise can cause impairment or
loss of hearing.
Wear a suitable hearing
protective device such as
earmuffs or earplugs to protect
against objectionable or
uncomfortable loud noises.
Operating equipment safety
requires the full attention of
the operator. Deo not wear
radio or music headphones while
operating machine.
Stay clear of rotating drivelines
Entanglement in rotating
driveline can cause serious
injury or death.
Keep tractor master shield and
driveline shields in place at
all times. Make sure rotating
shields turn freely.
Wear close fitting clothing.

1.0. Safety
Guard and shields
Keep guards and shields in
place all the times. Ensure
that they are in good condition
and installed correctly.
Always disengage the driveline,
shut off engine and remove key
before removing any guards or
shields.
Keep hands, feet and clothing
away from moving parts.
Avoid high - pressure fluids
Escaping fluid under pressure
can penetrate the skin causing
serious injury.
Avoid the hazard by relieving
pressure before disconnecting
hydraulic or other lines.
Tighten all connections before
applying pressure.
Search for leaks with a piece
of cardboard. Protect hands and
body from high pressure fluids.
If an accident occurs, see a
doctor immediately. Any fluid
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.

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 been damaged
or lost.
An implement safety lighting
kit is available from your
dealer.
Avoid heating near pressurized fluid lines
Flammable spray can be
generated by heating near
pressurized fluid lines,
resulting in severe burns to
yourself and bystanders. Do not
heat by welding, soldering,
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.
