4. Battery
General
o Charge the battery before use. The recharging time of an empty battery is about 7 hours. The
temperature of the battery to be recharged must be +10...+ 30 C.
o Recharging should always take place at a room temperature of about +20 C, in a dry place shielded
from dust and direct sunlight.
o The recharger
performs a battery test at start of each charging to detect defective batteries.
o Optimum performance with new battery packs is achieved only after they have completed three
charge-cycles.
Note!
o A new battery or a battery stored for a longer period or an over-discharged battery may not
function stably, which will terminate the recharging prematurely. Monitor the red signal light
(=charging in operation) after e.g. 30 or 60 minutes and initiate the recharging several times if
needed.
o In too cold/warm an environment the battery will not be charged.
o Never recharge in a potentially explosive environment!
o When not in use, prevent over-discharge of battery by keeping the blower device always on
recharge. Overcharging of battery is automatically prevented.
Recharging
Connect the recharging device to the main power supply (100-240 V/ 50 Hz). When not connected
to the blower device, the signal light will not start burning.
Push the recharging plug into the charging connector and turn the plug slightly clockwise until it sits
fast, otherwise the battery will not be charged. The charging will start automatically.
o red signal light remains on. The time needed depends
on the battery status.
o Recharging is complete when the red signal light goes out, and the green signal light starts burning
and stays on (standby level).
o The recharging plug will come off when you pull the locking and simultaneously turn the plug
counter-clockwise. Then close the protective lid.
