Mounting The Charger On A Wall; Led Diagnostics; Leds On The Battery - Stihl MSA 120 C Instruction Manual

14 LED Diagnostics

A battery is not fully charged when it ships from the factory.
STIHL recommends that you fully charge the battery before
using it the first time.
Operate the charger only indoors, in dry rooms and within an
ambient temperature range of 41 °F to 104 °F (5 °C to
40 °C).
The battery heats up during operation of the chain saw. If a
hot battery is inserted into the charger, it may be necessary
for it to cool down before charging starts. The charging
process begins only after the battery has cooled down
sufficiently.
Charging time depends on a number of factors, including
battery condition and the ambient temperature. For a
complete list of approximate charging times, see

13.3 Mounting the Charger on a Wall

Before mounting, ensure that no electrical cables, pipes or
other service lines run in the wall behind the charger.
To mount the wall charger:

► Mount the charger indoors in a dry room near an electrical
outlet.
► Sink the screws into a wall stud. Use appropriate screw-in
wall anchors or other similar mounting devices if an
appropriate wall stud is not available.
► Align the charger as shown above. Mount to a wall with the
following dimensions:
0458-716-8621-E
– a = minimum 18 in. (450 mm)
– b = minimum 3.9 in. (100 mm)
– c (for AL 101) = 3.0 in. (75 mm)
– c (for AL 300 and AL 500) = 4.7 in. (120 mm)
– d = 0.2 in. (4,5 mm)
– e = 0.4 in. (9 mm)
– f = 0.1 in. (2,5 mm)

14.1 LEDs on the Battery

14.1.1 Battery Status
Four LEDs show the status of the battery. These LEDs can
glow or flash green or red.
3
e
d
14.1.2 Chain Saw Status
f
When the battery is inserted in the chain saw, the same
f
LEDs on the battery will indicate the status of the chain saw.
If three LEDs glow red continuously: the chain saw motor is
too hot. Allow the motor to cool down.
If three LEDs flash red when you activate the trigger switch:
the chain saw has an electrical malfunction. Do not operate
the chain saw. Have it checked by an authorized STIHL
servicing dealer before use or storage.
For troubleshooting information, @ 25.
If one LED glows red continuously: the battery
is either too hot or too cold. Allow the battery
to warm up or cool down gradually at an
ambient temperature of about 50 °F to 68 °F
(10 °C to 20 °C).
If all 4 LEDs flash red: the battery has a
malfunction and must be replaced. Do not
attempt to charge, use or store the battery.
