field is wrong.
•In such a case, an electrician must change the direc-
tion of rotation inside the mains plug.
•The power supply to the machine must be fuse-pro-
tected with 16A secured with an AC/DC sensitive
ground-fault circuit interrupter (type B).
3Operating instructions
Please refer to the short instructions supplied with your machine for
the operation of your Tumbler.
Follow also the safety instructions in Chapter 1.1!
Depending on the user programs, the lid and drum are
moved automatically. While the program is running, no
person or object may stand or be located within the work-
ing range of the machine (front distance at least 1.2 m
over the entire machine width).
If the power fails when a user program is being executed
the machine will react as follows when the power supply
is reinstated: it will start up again automatically and the

Tumbler MKR 600

program will continue from that point at which it was in-
terrupted by the power failure.
In its respective life cycle phases (transport, commission-
ing, setup, operation, cleaning, decommissioning, care /
maintenance, dismantling / disposal) this machine is de-
signed for 1-person operation!
When using this machine, no other person may be present
near the machine. The exception (2-man operation):
•Installation and removal of drum lid
•Installation and removal of drum lid arms
•Installation and removal of tumbling arm
•Installation and removal of mixing arm
•Installation and removal of protective gearbox cover
•Transport of machine and machine parts
Depending on the user programs, temperatures down to -
10 C may be generated in the drum. Take the correspond-
ing precautions.
Do not touch the tumbling arm / mixing arm with your
hands or any object when they are moving! Their rota-
tional speed while the lid is open is restricted for safety
reasons!
Make sure before each lifting operation that both stand-
ard trolleys sit correctly in the standard trolley support of
the lifting aid!
No persons or objects may be present in the swivel range
of the drum!
When emptying the drum corresponding appropriate pre-
cautions must be taken to ensure that no person stands in
the discharge area of the machine!
Make sure when mounting (or adjusting) the tumbling arm
as well as the mixing arm (alternative blind plug) that
they are correctly locked!
No persons or interfering objects may be present in the
swivel range of the lid!

Tumbler MKR 600
11
The operator must make sure that no persons, who do not
know the hazards of the machine or cannot anticipate
them, are about in the area of the machine!
If the drum is inclined downwards and you aerate the
drum or even open the lid, the goods will fall out of the
machine.
Each time before you start working, make sure that the
drum lid seal has been inserted correctly. For this, check
during program start whether a pressure loss is indicated
on the pressure display (if the machine can create a vac-
uum). If this is the case, the gasket has been mounted cor-
rectly. Otherwise check the gasket.
The lid cannot be opened when there is a vacuum in the
machine or if it has not yet been fully aerated.
If you interrupt a program by pressing “Pause”, you will be
prompted to aerate when “Open lid” is actuated. Only af-
ter the drum has been evacuated will you be able to open
the lid by actuating it again.
Within a program you may aerate the machine before the
lid shall be opened.
The drum can be set to any position between
-10° and 100° (= discharging position) so that it can be
used for any operating process.
The control panel may only be operated by touching it
with the fingers. Using any objects (e.g. blade) is prohib-
ited!

unrelated to the part, always carry out a fault diagnosis.
For this reason, contact our Service Hotline at [phone] for
spare parts or technical faults. Please keep the machine type and
number ready.
6Disposal
1. The machine contains a cooling system filled with the refrig-
erant R404A. It must be pumped off by a refrigeration in-
staller and must then disposed of correctly!
2. The following components contain oil:
a. Lid drive
b. Tumbling arm drive
c. Slewing gear
d. Vacuum pump
e. Compressor (cooling unit)
