When using
When the tool is switched on, the lamps will light to indi-
cate 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.
