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 °C...+ 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
Always use the Proflow's own recharging device (it is delivered with the blower unit). 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.
•
Open the protective lid of the blower's charging connector.
•
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
Throughout the recharging, the recharger's 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.
