Oil
WARNING
■ Never operate your saw without bar and chain
lubrication. If the chain runs dry, the cutting
attachment will be damaged beyond repair
within a very short time. A damaged chain
may break, resulting in severe or fatal per‐
sonal injury. Always check chain lubrication
and the oil level in the tank before starting
work and periodically during work.
This chain saw is equipped with an adjustable oil
pump. The flow of bar and chain oil can be set
for different guide bar lengths, types of wood and
working techniques.
To adjust the flow of bar and chain oil:
► Switch off the chain saw,
► Remove the battery,
► Engage the chain brake,
The chain oil feed rate is suitable for most appli‐
cations when the oil flow adjusting screw (1) is in
position E (Ematic).
To increase the flow:
► Turn the oil flow adjusting screw clockwise.
Turn reduce the flow:
► Turn the oil flow adjusting screw counter-
clockwise.

16.1 Engaging the Chain Brake
WARNING
■ The chain brake will operate only if it has been
properly maintained and the front hand guard
has not been modified,
WARNING
■ No chain brake device prevents kickback. This
device is designed to reduce the risk of kick‐
back injury, if activated, in certain kickback sit‐
uations. For the chain brake to remain in good
working order, it must be properly maintained,
9.
In the event of a kickback, the chain brake is
designed to engage if the left hand contacts the
front hand guard and pushes it forward.
The chain brake is also designed to be activated
by the inertia of the front hand guard if the forces
are sufficiently high. When the brake is activated
by inertia, the hand guard accelerates toward the
bar nose, even if your hand is not behind the
hand guard.
Engaging the chain brake locks the chain. To
manually engage the chain brake:
► Push the front hand guard away from the front
handle.
You will hear an audible click when the front
hand guard reaches the locked position. If a bat‐
tery is inserted: The Chain Brake LED (1) lights
up.
16.2 Disengaging the Chain Brake
WARNING
■ Before disengaging the chain brake and
switching on your chain saw, be sure that the
guide bar and saw chain are clear of you and
all other obstructions and objects, including
the ground, 5.5.
