NOTE:
• If the indicator lamp does not turn on or flicker when
charging, the battery may be faulty. In this case, ask
your local service center.
When using
When the tool is switched on, the lamps will light to
indicate the remaining battery capacity. When the tool is
switched off, the light goes out after approx. 5 seconds.
When pushing the check button with the tool switched
off, the indicator lamps turn on for approx. 5 seconds to
show battery capacity.
If the orange lamp flickers, the tool stops because of little
remaining battery capacity (Auto-stop mechanism).
Charge the battery cartridge or use a charged battery
cartridge at this time.
When the tool is used with the battery that has not been
used for a long time and is switched on, no lamps may
light up. The tool stops because of little remaining battery
capacity at this time. Charge the battery properly.
