Attention: Dust-laden gases, deposits and condensed solvent vapour can restrict air flow out the si-
lencer. The resultant back pressure can lead to damage of pump bearings, diaphragms, and valves.
Under those conditions, a silencer must not be used.
Note: Some of the components on the printed circuit board are sensitive to electrostatic discharge.
Do not touch components. If necessary, ground the printed circuit board and the person replacing the
battery suitably.
Attention: Use only a battery of the recommended type (see ”Technical data”).
The battery must not be charged or connected to an external voltage.
➨ Remove the battery.
➨ Insert the new battery in the battery compartment correctly
matching the positive and negative polarity (as shown by
the engraving inside the compartment).
☞ When reassembling the vacuum gauge, make sure that
the switch pad and the printed circuit board are positioned
correctly.
➨ Carefully screw both parts of the housing together.
