3. Functional description
By means of the automatic pot dispenser empty pots are put on
the pot holders on the right side of the machine - when it is
viewed from front.
The pot holders on the console are moved counter clockwise.
The exact pot track movement is guaranteed by a special, high-
performance belt that is low-wear and low-maintenance. The
pot holders that are fixed to this belt by force-locking are also
supported in the outer track, thus preventing tipping.
The pots are forwarded under the elevator.
The excess substrate at filling is fed directly back to the soil
hopper after the drilling process and thus does not travel along
the entire potting track.
Plates are fixed on endless chains located in the elevator
housing which take the soil from the hopper. When the plates
reach the upper turning point the soil falls into pot being there.
An adjustable conveyor belt is installed inside the soil hopper
which forwards the soil always towards the elevator.
The pot holders that are fixed to the special belt move on and a
drilling motor being synchronous with the inching mechanism
drills a hole into the soil that’s inside the pot by means of a
replaceable drill.
One or several person(s) standing around the machine (or a
transplanter) may plant plants into the pots.
Plant holding trays may be located either beside the machine or
in a separate storing place in the middle of the console.
A pot take-off is installed to remove the planted pots from the
console and to push them on one or two conveyor belt(s)
connected to the machine.

2 General safety instructions
1. Due diligence of the operating company
The MAYER TM 2700 potting machine was designed
and built taking a danger analysis into consideration
and after careful selection of the harmonised
standards to be complied with as well as other
specifications. It therefore meets the state of the art
and guarantees a maximum degree of safety.
However, only if all the measures required for such
are taken can this safety be achieved in actual
operational practice. Planning these measures and
checking their implementation is subject to the
operating organisation's duty to take due care.
The operating organisation must in particular
guarantee that:
•… the machine is only used in accordance
with its intended use (cf. the Product
description section).
•… the machine is only operated when in
flawless working order and, especially,
that the working order of the safety
equipment is regularly checked.
•… the Operating Instructions are always
available in legible condition and complete
at the location where the machine is used.
•… only sufficiently qualified and authorised
personnel operate, service and repair the
machine.
•… these personnel are regularly instructed
about all relevant matters concerning
industrial safety and environmental
protection and that they know the
Operating Instructions and especially the
safety instructions they contain.
•… none of the safety and warning signs
attached to the machine are removed and
that all remain legible.
•Users must obligate themselves only to
ever operate the machine when it is
flawless condition.
•No unauthorised conversions or
alterations are allowed that influence the
machine's safety.
•Only when it has stopped, must any work
ever be carried out on the machine.
