I. Foreword

Dear customer,

We thank you for the trust you have placed in us by

purchasing this machine.

When you received the machine, the dealer should

have given you instructions for the operation, mainte-

nance and adjustment of the machine.

However, this brief introduction to the machine can

not replace a detailed acquaintance with the different

tasks and functions of the machine and the proper way

to treat it.

The operating instructions are designed so that you

are extensively informed of the activities required in

each area, from commissioning and operation to the

maintenance and care of the machine. The structure

of the individual chapters in the text and illustrations

corresponds to the sequence of work procedures when

you use the machine.

Read these operating instructions carefully before you

use the machine, and pay special attention to the

safety instructions.

Important: To avoid accidents and to ensure

maximum results, no alterations may

be made to the machine without the

manufacturer’s permission. Similarly,

the machine must only be used under

the conditions prescribed by Krone.

All information, illustrations and technical information in

these operating instructions represent the latest status

at the date of publication. The company reserves the

right to make constructional alterations at any time and

without prior notice or obligation.

This symbol is designed to draw attention

to the safety instructions contained in the

operating instructions. These instructions

must be observed to prevent accidents

Year

When ordering replacement parts, the type designation,

machine number and year of manufacture must be

given. These details can be found on the identification

label on the machine.

We recommend that these details be entered in the

above boxes so that they are readily available.

Please remember that imitations and copies of parts,

especially wearing parts, do not keep what they appear

to promise. Material quality is difficult to test visually,

therefore special care is required when purchasing

cheap offers and imitation parts!

The simplest remedy:

Purchase only original KRONE parts!

You will find this symbol at various points

in the operating instructions. It gives

special handling instructions which

should be particularly observed in the

use of the machine.

Preparing for operation

2 Preparing for operation

Special safety notes

• Keep a sufficiently safe distance from the cutting tools during operation.

• Even when the mower is used in accordance with specifications, stones etc. may be

thrown out. Therefore, no-one shoud be standing in the danger area. Particular care

should be taken when working near roads or buildings.

• Check the protective cloth covers regularly. Replace worn or damaged protective

cloth covers.

• The protective devices on the mower unit, e.g. cloths and guard plates, should be

engaged before starting work.

• No-one must be allowed to walk between the tractor and the mower, when the mower

is being moved from transport postion to mowing position or back to transport

position.

• Particular care is required when fitting attachments to the tractor or removing them!

It is essential that the accident prevention regulations are observed.

• The mower unit is hitched off centre. When braking in dangerous situations

(cornering on slippery ground) the tractor can jack-knife. The minimum unladen

weight of tractor of 4000 kg should therefore be fulfilled.

2.1 Preparing the disc mower

Assemble the PTO shaft (1) with extended guard (2) on

to the machine. Hang the retaining chain (4) in the hole

(3) to prevent the protective tube (5) from turning with

the shaft.
