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

Pöttinger 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):

1

- 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.
