2.1 General safety instructions

Please read carefully!
The can be used in combination with hazardous materials, work processes and equipment. However,
the operating manual cannot cover all of the safety issues that may occur in doing so. It is the user's
responsibility to ensure compliance with the safety and health regulations and to specify the corre-
sponding restrictions before use.
1.
Every user must read and understand this operating manual before operation.
2.
Follow the general hazard instructions and safety regulations, e.g. wear protective clothing,
eye protection and protective gloves.
3.
Observe all specifications provided by reagent manufacturers.
4.
When dispensing inflammable media, make sure to avoid to buildup of static charge, e.g., do
not dispense into plastic vessels; do not wipe instruments with a dry cloth.
5.
Use the instrument only for dispensing liquids, with strict regard to the defined limitations of
use and operating limitations. Comply with the operating exclusions; see Operating Exclu-
sions, p. 35. If in doubt, contact the manufacturer or supplier.
6.
Always perform work in a manner that does not endanger yourself or other people. When dis-
pensing, the discharge tube must always point away from you or any other person. Avoid
splattering. Only use suitable vessels.
7.
Never press down the piston when the discharge tube closure is attached.
8.
Never remove the discharge tube while the dispensing cylinder is filled.
9.
Reagents can accumulate in the screw cap of the discharge tube. Thus, the screw cap should
be cleaned regularly.
10.
To prevent tipping, use a bottle stand – particularly with small bottles and when using the flex-
ible discharge tube.
11.
When mounted to a bottle, never carry the instrument by the cylinder sleeve or the valve
block. Breakage or loosening of the cylinder can lead to personal injury from chemicals, see
First Steps, p. 38, Fig. 4.
12.
Never use force. Use smooth gentle movements to operate the piston upwards and down-
wards.
13.
Use only original accessories and original replacement parts. Do not make any technical modi-
fications. Do not dismantle the instrument any further than is described in the operating man-
ual!
14.
Always check that the instrument is in proper working condition before use. The user can
come into contact with media if the instrument has been insufficiently cleaned or inspected. If
there is a sign of a potential malfunction (e.g., piston difficult to move, sticking valves or leak-
age), immediately stop dispensing and consult the Troubleshooting, p. 53 section. Contact
the manufacturer, if necessary. In case of discolorations, check if any material fatigue is
present. If there is any doubt, replace components.
15.
Always tighten the retaining ring between the valve block and dispensing cylinder by hand. Do
not use any tools.
16.
Autoclaving the instrument is not permitted!
