4.1

Safety Instructions Safe operation of the mower unit is only possible through appropriate use of the cutting blades according to directions.

Check the mower unit every time it will be used for damaged, missing and worn cutting blades and replace cutting blades if necessary!

Only replace missing and damaged mower blades in sets as specified by the manufacturer to prevent danger resulting from imbalance !

Check the parts fastening the blades at every change of cutting blades according to regulations specified by the manufacturer and replace if necessary!

It is most of all important to check the degree to which the blade holding bolt has been worn down on its inner radius by the blade. It must be replaced by a new unused blade holding bolt at the latest when a groove depth of 3 mm has been reached, that is a reduction of the inner radius by 3 mm.

The riveting on the blade bolt in the knife holder as well as the wear on the knife holder on the outer edge are to be checked. All knife holders on the cutting disc, knife must be replaced by new knife holders if necessary.

The safety guards must be checked regularly and worn or damaged safety guards must be replaced!

Protective equipment on the mower unit, for example canvases and hoods, protect against flying stones and the like as well as from access to dangerous areas. For this reason they must be placed in safety position before starting work!

Squashing and shearing points arise while the mower unit is being swivelled from the transport position into the working position and vice versa.

For this reason, keep out of the area between the tractor and the mower unit. The swivelling process must take place with the mower unit in a horizontal condition.

The glide discs must be in contact with the ground before putting into operation and while working!

Stones and similar objects can be thrown out even when the mower unit is being used correctly. Therefore, no-one should be in the danger zone.

Special care is required when working near roads and buildings!

The working tools cab run on after switching off the drive. Do not approach them until they have stopped.

If an obstacle is run over, stop the mower unit immediately and check for damage!

4.2

Wear close-fitting clothing when working on the front attachment. Do not wear loose clothing!

Keep the machine clean to prevent fire!

Before starting and before putting it into operation check the area around the machine (children!).

Ensure that you have an adequate view!

Passengers must not be carried on the machine while working or during transport!

Always connect the implement correctly to the tractor and connect and secure the machine to the prescribed couplings!

Always place the jack in the appropriate position when hitching and unhitching the machine – stability!

Use special care when hitching the machine to the tractor and when unhitching the machine!

Make sure that balance weights are correctly fixed at the provided points!

Observe the permissible transport dimensions!

Observe the maximum permissible axle loads and total weights!

Check and mount transport equipment – such as lights, warning devices, and if required protecting devices and guards!

Operating devices (ropes, chains, linkages etc.) of remotely controlled mechanisms must be positioned in such a way that they do not trigger unintentional operation in any transport or operating position!

For road travel prepare the machine and lock any moving parts as prescribed by the manufacturer!

Never leave the operator's platform when driving!

Always adapt your ground speed to the ground conditions! Avoid making sharp turns when driving up or down slopes or when driving across the slope!

The operating, steering and braking behaviour will be affected by the trailed machine! Therefore ensure adequate steering and braking power!

When making turns, always take into consideration the width and/or inertia of the implement!

Only operate the machine when all guards are fitted and in the correct position!

Ensure all persons stand clear of the operating area and of the area of danger!

Keep clear of the swivelling range of the operating machine.

Watch for pinch and shear points on parts that are operated, for instance by hydraulics!

BA DISCO 2650 RC Plus / 2650 RC - 0299 720.4

Operation Environmental recommendations Simple changes to accustomed mowing procedures can help reduce injuries and fatalities to wildlife.

At the same time, the forage quality is improved.

Environment!

Mowing from the outside to the inside leaves wild animals little chance to escape!

– For this reason, mow from the inside to the outside.

Drive to the centre of the section to be mown and mow from the inside to the outside.

The central patch can be mown as soon as there is enough space to turn.

This gives wild animals the chance to flee in an outward direction.

(Fig. 18)
