1 Introduction
1.1 Instrument description
The 786 Swing Head is an auxiliary drive for the Sample Processors from
Metrohm, e.g. the 815 USB Robotic Sample Processor XL. It extends the
capabilities
precisely to any given position on a sample rack. The working area of the
Sample Processors is now being expanded even further. Now, even positions
outside of the sample rack can be moved to as a result. It is thus possible to
transfer samples from the sample rack into separate working stations in just
a few simple steps.
This is a high-precision motor drive, which is mounted on the tower of a
Sample Processor. Robotic arms of different construction types are available
for assembly on the 786 Swing Head. Equipped with the corresponding
accessories, these can be used for applications requiring a high degree of
flexibility or very complex working steps.

medical environments in its basic equipment version.
This instrument is suitable for transferring chemicals and flammable solvents.
The usage of the 786 Swing Head therefore requires that the user has basic
knowledge and experience in the handling of toxic and caustic substances.
Knowledge with respect to the application of the fire prevention measures
prescribed for laboratories or production plants is also mandatory.
Swing Head is designed for usage in an automation system in ana-

1.5 Safety instructions
1.5.1 General notes on safety
Warning
This instrument may only be operated in accordance with the specifications in this documentation.
1 Introduction
Warning
This symbol draws attention to a possible biological
hazard.
Caution
This symbol draws attention to a possible damage of
instruments or instrument parts.
Note
This symbol marks additional information and tips.
This instrument has left the factory in a flawless state in terms of technical
safety. To maintain this state and ensure non-hazardous operation of the
instrument, the following instructions must be observed carefully.
1.5.2 Electrical safety
electrical safety when working with the instrument is ensured as part of
The
the international standard IEC 61010.
Only personnel qualified by Metrohm are authorized to carry out service

1.5.3 Tubing and capillary connections
Caution
Leaks in tubing and capillary connections are a safety risk. Tighten all
connections well by hand. Avoid applying excessive force to tubing connections. Damaged tubing ends lead to leakage. Appropriate tools can
be used to loosen connections.
Check the connections regularly for leakage. If the instrument is used
mainly
in unattended operation, then weekly inspections are mandatory.
1.5.4 Personnel safety
Warning
Wear protective goggles and working clothes suitable for laboratory work
while operating the 786 Swing Head. It is also advisable to wear gloves
when caustic liquids are used or in situations where glass vessels could
break.
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
Warning
Always install the safety shield supplied with the equipment before using
the instrument for the first time. Pre-installed safety shields are not
allowed to be removed.
The 786 Swing Head may not be operated without a safety shield!
Warning
Personnel are not permitted to reach into the working area of the instrument while operations are running!
A considerable risk of injury exists for the user.
Warning
In the event of a possible blockage of a drive, the mains plug must be
pulled out of the socket immediately. Do not attempt to free jammed
sample vessels or other parts while the device is switched on. Blockages
can only be cleared when the instrument is in a voltage-free status; this
action generally involves a considerable risk of injury.
