English
► Lower the push handle to lock the arms in
their seats.
5 Connecting Charger to
Power Supply
Power supply (mains) voltage and operating volt‐
age must be the same.
► Insert the plug (1) in the wall outlet (2).

A self test is performed after the charger is con‐
nected to the power supply. During this process,
the light emitting diode (1) on the charger lights
up green for about 1 second, then red and goes
off again.

Charging the Battery

A factory-new battery is not fully charged.
Recommendation: Fully charge the battery
before using it for the first time.
► Connect the charger to the power supply –
mains voltage and operating voltage of the
charger must be the same – see "Connecting
Charger to Power Supply".
Operate the charger only in enclosed and dry
rooms at ambient temperatures between +5°C to
+40°C (+41°F to +104°F)
Only charge dry batteries. Allow a damp battery
to dry before charging.

► Push the battery (1) into the charger (2) until
noticeable resistance is felt – then push it as
far as stop.
The LED (3) on the charger comes on when the
battery is inserted – see "LED on Charger"
Charging begins as soon as the LEDs (4) on the
battery glow green – see "LEDs on Battery".
The charge time is dependent on a number of
factors, including battery condition, ambient tem‐
perature, etc., and may therefore vary from the
times specified.
The battery heats up during operation in the
power tool. If a hot battery is inserted in the
charger, it may be necessary to cool it down
before charging. The charging process begins
only after the battery has cooled down. The time
required for cooling may prolong the charge time.
The battery and charger heat up during the
charging process.
6.1
The AL 300 and AL 500 chargers are equipped
with a battery cooling fan
6.2
The AL 100 charger has no fan and waits for the
battery to cool down before starting the charging
process. The battery is cooled by heat transfer to
the ambient air.
