3.2.4 Space for servicing
The area above the machine must not contain any equipment which could pre-
vent the fitting, servicing and replacement of parts. A free height of at least 2.8
metres is required in order to remove the inspection doors.
A 1-metre free space should be allowed in front of the machine and around the
infeed and outfeed ends for service purposes.
3.3 Transport and storage
Check that there is sufficient height available to transport the machine to its instal-
lation site.
The machine is supplied in sections with a pallet under each section. Transport
each section to the installation site using a handtruck.
The sections are transported transversely with the forks of the truck inserted from
the long side. (The side marked “FRONT”). If the space available does not permit
transverse transport, each section should be transported using two handtrucks,
one at each short end. Do not lift the machine by its legs. These are indicated by
labels on the outside of the packaging.
