Directive
2006/42/EC
UNI EN 5674
UNI EN 4254-1
Assemble suitable casings and protections
along the entire length of the shaft and of the
universal joints.
Blocking and guards/protective devices must
be in good conditions.
The guard on the header side must overlap
the guard of the PTO drive shaft (off-centre)
for at least 50 mm, in order to avoid contact
with moving parts.
The header must be equipped with
appropriate coupling devices to avoid the
rotation of PTO drive shaft.
When the header is not coupled to the
combine, it must be equipped with a support
for the PTO drive shaft (this support cannot
be the coupling point mentioned above).
D.1.3.
Detachment of the machine
The detachment of the header from the combine, should be performed placing the
machine on a compact, flat surface with the power off and the exit openings closed.

Machinery
Directive
2006/42/EC
UNI EN 4254
If necessary, provide the header with
appropriate supports in order to avoid the
overturning.
Except for the wheels, the support devices
must limit the contact pressure with the
ground to 400 kPa (maximum).
The machine is specifically designed to stay
stable (when not attached to a combine), on a
hard surface with an inclination of about 8.5°
in all directions.
The header is equipped with appropriate
safety warning labels positioned in the vicinity
of hazard zones. Comply with the directions
given in the instruction manual.
