Operation
Avoid letting the area of the saw rail depicted on the right touch wood
GB
or other hard objects.
In order to reduce the risk of injury in case of a rebound, the device is
equipped with a chain brake which is triggered automatically on
impact and which stops the saw chain immediately.
For safety reasons, the functionality of the chain brake must be
checked each time the device is used (▸ Checking the chain brake –
p. 104).
With less strong rebounds, it can happen that the chain brake is not triggered automatically. For this
reason it is important that the device be held fast with both hands.
Only a careful and correct working method can reduce the risk of a rebound reliably!

Basic work technique

DANGER!
Risk of injury!
This section treats the basic work technique when handling the device. The information
provided here does not replace the many years of training and experience of a profes-
sional.
Avoid any work for which you are not sufficiently qualified! Thoughtless handling of the
device can cause severe or even fatal injuries!
Before each use
– Check the chain brake (10) to ensure it is functioning correctly.
– Checking the tensioning of the saw chain (7).
– Check the chain catcher for damage.
– Check the on/off switch (3) to ensure it is functioning correctly.
– Check the throttle block (17) to ensure it is functioning correctly.
– Check whether all handles are free of oil.
– Check whether all parts of the device are present, firmly attached and undamaged.
Sawing technique
Pulling sawing
With this technique, sawing occurs with the underside of the saw rail
from above downwards. The saw chain thus pushes the device for-
wards away from the user. This way, the front edge of the device forms
a support, which catches the forces which arise on the tree trunk when
sawing.
With pulling sawing, the user has much more control over the device
and can avoid rebounds better. Therefore, this is the preferred sawing technique.
Pushing sawing
With this technique, sawing occurs with the upper edge of the saw rail
from below upwards. The saw chain thus pushes the device backwards
towards the user. If the saw rail twists, the device can fly towards the
user with great force.
