16 Inserting and Removing the Battery

Disengaging the chain brake unlocks the chain. To
disengage the chain brake:
► Pull the front hand guard toward the front handle.
You will hear an audible click when the front hand guard
reaches the unlocked position. If the chain saw is switched
on and the saw is in standby mode, the "CHAIN BRAKE"
LED (1) goes out. In this position, the chain brake is
disengaged.

15.3 Maintaining the Chain Brake

WARNING
An improperly maintained chain brake may increase the time
needed to stop the saw chain after activation, or it may not
activate or stop the chain at all, @ 7.2. The chain brake is
subject to wear, depending on the amount of usage,
conditions under which the saw is used and other factors.
Excessive wear will reduce the effectiveness of the chain
brake and can render it inoperable.
► Your chain saw should be returned to your authorized
STIHL servicing dealer for periodic inspection and
servicing of the brake system according to the following
schedule:
– Heavy Usage: every 3 months
– Part-Time Usage: every 6 months
– Occasional Usage: every 12 months

16.1 Inserting the Battery

WARNING
Never use a malfunctioning, damaged, cracked, leaking or
deformed battery, @ 9. Use and store the battery only
within an ambient temperature range of 14 °F to 122 °F (- 10
°C to 50 °C), @ 9.
WARNING
To reduce the risk of unintended activation, never store the
battery in the chain saw, @ 22.2.
To insert the battery:
► Engage the chain brake, @ 15.1.
► Place the chain saw on a level surface.
► Insert the battery (1) into the battery compartment (2) until
it stops.
The battery is properly inserted when you hear an audible
click and the battery is flush with the top of the housing. In
this position, there is electrical contact between the
battery and the chain saw.
Since a new battery is not fully charged, STIHL recommends
that you fully charge the battery before using it the first time,
@ 12.2.
