below 10 °C or above 40 °C. Recommended charging tem-
perature: approx. 24 °C.
Note: The charger will not charge a battery if the cell
temperature is below approximately 10 °C or above 40 °C.
The battery should be left in the charger and the charger
will begin to charge automatically when the cell tempera-
ture warms up or cools down.
u To charge the battery (4), insert it into the charger (19).
The battery will only t into the charger in one way. Do
not force. Be sure that the battery is fully seated in the
charger.
u Plug in the charger and switch on at the mains.
The charging indicator (20) will ash green continuously
(slowly).
The charge is complete when the charging indicator (20)
lights green continuously. The charger and the battery can be
left connected indenitely with the LED illuminated. The LED
will change to ashing green (charging) state as the charger
occasionally tops up the battery charge. The charging indica-
tor (20) will be lit as long as the battery is connected to the
plugged-in charger.
u Charge discharged batteries within 1 week. Battery life will
be greatly diminished if stored in a discharged state.
Leaving the battery in the charger
The charger and battery pack can be left connected with the
LED glowing indenitely. The charger will keep the battery
pack fresh and fully charged.
Charger diagnostics
If the charger detects a weak or damaged battery, the charg-
ing indicator (20) will ash red at a fast rate. Proceed as
follows:
u Re-insert the battery (4).
u If the charging indicators continues ashing red at a fast
rate, use a different battery to determine if the charging
process works properly.
u If the replaced battery charges correctly, the original
battery is defective and should be returned to a service
centre for recycling.
u If the new battery gives the same indication as the original
battery, take the charger to be tested at an authorised
services centre.
Note: It may take as long as 30 minutes to determine that
the battery is defective. If the battery is too hot or too
cold, the LED will alternately blink red, fast and slow, one
flash at each speed and repeat.

Hints for optimum use
General
u In order to achieve optimum cutting results, only cut dry
grass.
Trimming
u Hold the tool as shown in g. J
u Gently swing the trimmer from side to side.
u When cutting long grass, work in stages from the top. Take
small cuts.
u Keep the tool away from hard objects and delicate plants.
u Cutting line will wear faster and require more feeding if
the cutting is done along pavements or other abrasive
surfaces or heavier weeds are being cut.
u If the tool starts running slowly, reduce the load.
Edging
Optimum cutting results are achieved on edges deeper than
50 mm.
u Do not use the tool to create edges. To create edges, use
an edging spade.
u Guide the tool on its wheel (10) or edge guide (11) as
shown in g. K.
u To make a closer cut, slightly tilt the tool.
