The new STIHL FSA 65, 85 cordless trimmers are
the latest additions to the STIHL line of battery-
powered garden tools.
Sophisticated lithium-ion battery technology, the
time-proven AUTOCUT® C mowing head principle
and the high power of the electric motor provide the
user with a new dimension in cutting performance
for handheld, cordless trimmers.
Battery power allows excellent maneuverability
without exhaust fumes or a power cord.
Ease of use, optimized balance and low vibrations
help reduce operator effort.

It also minimizes wear, reduces the space required
and keeps the noise level low. 1.5 Retaining Latch, Trigger Switch Lockout
An electronic module converts the battery voltage to
the voltage required by the motor and controls the 1
motor in response to the position of the trigger
switch. The electronic module monitors the motor's 2
condition at all times and makes adjustments if
necessary. This guarantees a constant cutting
performance over the entire running time.

The unit can be locked or unlocked as required with
the retaining latch (1). The trigger switch lockout (2)
is an additional safety feature that helps avoid
unintentional operation of the trigger (3).

Charging principle
The charger charges the battery in two stages. The
battery is first charged at a constant current up to a
preset voltage limit. The charger then switches over
to charging at a constant voltage. The charge
current is reduced automatically until it drops below
a given minimum or the preset total charge time is
exceeded. The charger then switches itself off
automatically.

The charger can charge the battery only if data

Contact between the battery and charger will be
insufficient if the battery is not inserted properly in
the charger. In such a case the light emitting diode
