2.2 Personnel qualication requirements
The operator is obliged to inform all the users about correct application
of the machine and the respective hazards. This can be done on the
basis of these operating instructions. The operator is responsible for
ensuring that the operating instructions are always available at the
machine and that the users observe the operating instructions. The
operator must also provide any necessary personal protective equip‐
ment.
Users are persons who drive, adjust, operate or maintain the machine.
Users must be able to use the machine safely. This means:
nUsers understand how the machine works.
nUsers know and are able to avoid dangers.
nUsers are physically capable of controlling the machine.
In order to use the machine as intended and in a professional manner,
users must have the required technical (agricultural) knowledge.
Unless otherwise indicated, users may carry out all activities described
in these operating instructions themselves.
Certain activities should only be performed by service personnel, e.g.

The parked machine may overturn. This may result in fatal or serious
injuries.
►Park the machine in operating position.
►Park the machine on rm and level ground only.
►Place a plate (metal, wood, stone) with sucient carrying capacity
under the stands.
The machine is equipped with components in which mechanical
energy is stored (e.g. springs, overload safety units). Uncontrolled
release of mechanical energy accelerates components like a projectile.
This may result in fatal or serious injuries.
►NEVER dismantle or open components that store mechanical
energy.
The hydraulic system is under high pressure. Leaking hydraulic oil can
penetrate through the skin into the body.
Risk of injury to body parts, face, eyes and unprotected skin areas
The hydraulic oil may be hot.
The hydraulic oil is harmful to health.
►When working on the hydraulic system:
Wear safety goggles and gloves.
►Check the condition of the hydraulic system according to the main‐
tenance schedule. Replace damaged or worn components of the
hydraulic system immediately.
►NEVER touch leaks without hand protection.
►If hydraulic oil has penetrated the body:
Seek medical attention immediately. Remove the hydraulic oil from
the body as quickly as possible. Risk of infection
2.4 Workplaces and passengers
The main workplace for working with the machine is the driver's seat in
the tractor. Further workplaces are described in the respective instruc‐
tions for action.

2.6 Safe handling
2.6.1 Personal protective equipment
Carrying and wearing protective equipment is an important safety
component.
Lack of or inappropriate protective equipment increases the risk of
damage to health and injury to persons.
For certain work on the machine, the following protective equipment is
required in addition to suitable workwear:
nSafety gloves
Use protective equipment as follows:
►Only use protective equipment that is in proper condition.
►Only use protective equipment that provides eective protection.
►Adapt protective equipment to the respective person, e.g. size.
2.6.2 Driving the tractor-machine combination
Mounted or trailed machines change the driving characteristics of the
tractor.
The driving characteristics also depend on the operating status, the
lling or loading and on the subsoil.
If the driver does not consider changed characteristics, accidents may
occur.
►Observe changed driving behaviour when driving.
Ä Chapter 5 ‘Road travel’ on page 34
An insuciently secured and unattended tractor-machine combination
is a danger to persons, e.g. children playing.
►Before leaving: Stop the tractor-machine combination.
nEngage the parking brake.
nTurn o the engine.
nRemove ignition key.
►Before continuing to drive: Check the safe condition of the tractor-
machine combination again.
