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 BELONG to the 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. Furthermore, the corresponding US dimensions are also stated
in each case. 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 MACHINE IS DESIGNED EXCLUSIVELY for winter services clearing snow
from roads and grassy areas (“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. Using the equipment in accordance with the
specifications also includes observance of the operating and
maintenance conditions as specified by the manufacturer.
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
personnel familiar with the equipment and who are aware of the
dangers involved. The relevant accident prevention regulations, all
other generally recognised safety-related, occupational medicine and
road traffic regulations must be adhered to. Unauthorised
modification to the machine exonerates the manufacturer from
liability for any resulting damage.

All information, illustrations and specifications in these Operating Instructions are based on the latest information available at the time of
publication. We reserve the right to make design changes at any time without prior notification. 5

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.

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.

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.
