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
-
CHARGED BATTERY
–
Take out the battery.
–
Battery and electrolyte must be at equal temperature
above 10 °C.
–
Remove cover and/or plug from each cell.
–
Fill each cell with electrolyte until the level reaches 10 to 15
mm above the plates, or to the level marked on the battery.
–
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.
–
Refit plugs and/or cover.
–
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.
4.7.4 B
ATTERY MAINTENANCE
–
Keep the battery clean and dry
–
Keep the electrolyte level at 10 to 15 mm above the plates
or at the indicated level; top up with distilled water only.
–
Keep the terminals and clamps tight, clean, and lightely
covered with petroleum jelly.

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.

ERVICE KITS
A service kit is a collection of parts to fit a specific repair or
rebuilding task.
It guarantees that all necessary parts are replaced at the
same time which improves the uptime of the unit.
The order numbers of the Service Kits are listed in the Atlas
Copco Parts List (ASL).
Contact Atlas Copco.

OMPRESSOR ELEMENT OVERHAUL
When a compressor element is due for overhaul, it is
recommended to have it done by Atlas Copco. This
guarantees the use of genuine parts and correct tools with
care and precision.
