INTRODUCTION
1700_GB-Introduction
Introduction
Dear Customer
These Operating Instructions are intended to allow you
to familiarise yourself with the implement and provide
you with clear information on safe and correct handling,
care and maintenance. Thus please take the time to read
these Instructions.
These Operating Instructions comprise part of the imple-
ment. They are to be kept at a suitable location and acces-
sible to staff over the entire service life of the implement.
Instructions based on the national provisions regarding
protection against accidents, road traffic and environmental
protection are also to be applied additionally.
Any persons commissioned with the operation, maintenance
or transport of the implement must read and understand
these Instructions, in particular the safety information, prior
to starting work. Any warranty claims lapse on non-obser-
vance of these Instructions.
In case you have questions related to this operation manual
or further questions about this implement, please contact
your dealer.
Care and maintenance performed in good time and scru-
pulously according to the maintenance intervals specified
ensure operational and traffic safety as well as the reliability
of the implement.
Use only the original spare parts and accessories from
ttinger or accepted by Pöttinger. For those parts relia-
bility, safety and suitability for Pöttinger machines can be
assured. Warranty claims lapse if non-approved parts are
used. The use of original parts is also recommended after
the warranty period has expired to maintain the performance
of the implement in the long term.
Product liability legislation obliges the manufacturer and
the authorised dealer to issue Instructions when selling
implements and to instruct customers in the use with refer-
ence to the safety, operating and maintenance regulations.
Confirmation in the form of a declaration of transfer is
required to verify that the implement and Instructions have
been transferred correctly. The declaration of transfer was
attached to the implement on delivery.
Every self-employed person and farmer is an entrepreneur
within the meaning of the product liability legislation. In
accordance with the laws of product liability, entrepre-
neurial property damages are excluded from the liability.
All damage to property within the meaning of the product
liability legislation is regarded as damage caused by the
implement but not to the implement.
These Operating Instructions are integral part of the imple-
ment delivery scope. You should therefore hand them over to
the new owner if ownership of the implement is transferred.
Train and instruct the new owner in the regulations stated.
The Pöttinger Service-Team wishes you good luck.

Rotor Speed
Requirement:
The speed of the rotors may be pre-selected depending on
the tractor power and ambient conditions. This is carried
out either by way of the pre-selected PTO drive shaft speed
of the tractor or by the position of the gearwheels in the
rotary harrow’s transmission.
PTO shaft speed:
The recommended speed of the tractor’s PTO drive shaft
is 1,000 rpm. The lowest torque occurs at this speed and
this protects the drive components.
The speed of the tractor’s PTO drive shaft may be reduced
to 750 rpm or 540 rpm on soft ground or with a low working
depth.
Reposition the gears in the transmission of the
rotary harrow (only version WG):

- stop the tractor
- raise the rotary harrow and simultaneously
lower the rotational speed of the PTO drive shaft.
If the rotors are free from blockages, the cam-type cut-
out clutch of the PTO drive shaft engages again audibly
due to the reduced speed, and work can be continued.
The rotors must be freed of the blockage or obstacle if they
do not start to rotate.
CAUTION
Mild injury risk - due to thrown off parts which are
not covered by the protective cover.
Refer people out of the danger area.
Stop drive of the machine as soon as any-
body approaches it.
