ATTERY CARE
Before handling batteries, read the relevant safety
precautions and act accordingly.
An ASB (Service Bulletin) dealing elaborately with batteries and due
care is available on request.
If the battery is still dry,it must be activated as described in point
4.7.1.
The battery must be in operation within 2 months from being
activated; if not, it needs to be recharged first.
4.7.1 A
CTIVATING A DRY
Ð Take out the battery.
Ð Battery and electrolyte must be at equal temperature above 10 ¡C.
Ð Remove cover and/or plug from each cell.
Ð Fill each cell with electrolyte until the level reaches 10 to 15 mm
above the plates, or to the level marked on the battery.
Ð Rock the battery a few times so that possible air bubbles can
escape; wait 10 minutes and check the level in each cell once
more; if required, add electrolyte.
Ð Refit plugs and/or cover.
Ð Place the battery in the compressor.
4.7.2 E
LECTROLYTE
Read the safety instructions carefully
Electrolyte in batteries is a sulphuric acid solution in distilled water.
The solution must be made up before being introduced into the
battery.
4.7.3 R
ECHARGING A BATTERY
Before and after charging a battery, always check the electrolyte level
in each cell; if required, top up with distilled water only. When
charging batteries, each cell must be open, i.e. plugs and/or cover
removed.
Use a commercial automatic battery charger according
to its manufacturer's instructions.
Apply with preference the slow charging method and adjust the
charge current according to the following rule of thumb:
battery capacity in Ah divided by 20 gives safe charging current in
Amp.

TORAGE
Run the compressor regularly, e.g. twice a week, until warm.
Load and unload the compressor a few times to operate the unloading
and regulating components. Close the air outlet valves after stopping.
If the compressor is going to be stored without running
from time to time, protective measures must be taken as
described in a separate Service Bulletin (ASB), which
may be obtained on request.
