Starting Operation

For Your Safety

Warning! Switch off, remove the isolator switch and
the battery before adjusting or cleaning. The same ap-
plies when the cable to the switch in the handle is
damaged, cut or entangled.

The blade continues to rotate for a few seconds after
the machine is switched off.

Caution: Do not touch the rotating blade.

Charging the Battery

The battery is equipped with temperature monitoring that al-
lows charging only in the temperature range between 0 °C
and 35 °C. In this manner, a high battery service life is
achieved.

Note:

The battery is supplied partially charged. To ensure

full battery capacity, completely charge the battery in the
battery charger before using for the first time.
The lithium-ion battery can be charged at any time without
reducing its service life. Interrupting the charging procedure
does not cause damage to the battery.
The “Electronic Cell Protection (ECP)” protects the lithium-
ion battery against deep discharging. When the battery is
empty, the product is switched off by means of a protective
circuit: The product no longer operates.

Do not continue to press the On/Off switch after an auto-
matic shut-off of the product.

The battery could become

damaged.
Observe the notes for disposal of the battery.

Inserting/Removing the Battery

Note:

Using unsuitable batteries can lead to malfunctions or

damage the machine.
Insert the charged battery. Ensure the battery is inserted
correctly.
To remove the battery from the machine, press the battery
unlocking button and pull the battery out.

Charging Procedure

The charging procedure starts as soon as the mains plug of
the charger is plugged into a socket outlet and the battery is
inserted onto the charger .
Due to the intelligent charging method, the charging condi-
tion of the battery is automatically detected and the battery
is charged with the optimum charging current, depending on
battery temperature and voltage.
This gives longer life to the battery and always leaves it fully
charged when kept in the charger for storage.

charger (AL 3620 CV/AL 3640 CV/AL 36V-20)

Rapid-charging Procedure

The rapid-charging procedure is indicated by

flashing

of the

green

battery charge indicator.

Indication element of the battery: During the

charging procedure, the three green LEDs light up one after
the other and briefly go out. The battery is fully charged
when the three green LEDs light up continuously. The three
LEDs go out again approx. 5 minutes after the battery has
been fully charged.

Note:

The rapid-charging procedure is only possible when

the battery temperature is within the allowable charging
temperature range, see section “Technical Data”.

Battery charged

Continuous lighting

of the

green

LED indic-

ator indicates that the battery is fully charged.
Additionally, a signal tone sounds for approx.

2 seconds, which acoustically indicates that the battery is
fully charged.
Afterwards, the battery can be removed for immediate use.
When the battery is not inserted,

continuous lighting

of the

LED indicator indicates that the mains plug is inserted in the
socket outlet and that the battery charger is ready for opera-
tion.

Battery Temperature below 0°C or above 45°C

Continuous lighting

of the

red

LED indicator

indicates that the temperature of the battery is
not within the allowable charging temperature

range, see section “Technical Data”. As soon as the allowable
charging temperature range is reached, the battery charger
automatically switches to rapid charging.
When the battery is not within the allowable temperature
range, the red battery LED lights up when inserting the bat-
tery into the battery charger.

No Charging Procedure Possible

If a different malfunction of the charging pro-
cedure is present, this will be indicated
through

flashing

of the

red

LED indicator.

The charging procedure cannot be started and the battery
cannot be charged (see section Troubleshooting).
