chain and rail after a maximum of 5 cuts.
Checking the tensioning of the saw chain
WARNING!
Risk of injury!
A new saw chain must be re-ten-
sioned after a maximum of five cuts.
This is normal during the run-in time;
the intervals between subsequent re-
tensionings will get larger.
The saw chain is tensioned correctly if it lies
close against the underside of the saw rail
and can be moved easily by hand.
Readjust tension of the saw chain when nec-
essary (►Re-tensioning the saw chain –
p. 16).
If there is sufficient chain greasing, the oil
spraying off of the saw chain will form a slight
trail.
Checking the chain brake
The chain brake ensures immediate blocking
of the saw chain in case of a rebound. Before
beginning work with the device, it must be
checked to ensure that it is functioning cor-
rectly.
– Set device on the ground.
– Start the device.
– Tip the hand guard forwards. The chain
must stop immediately.
– If the chain brake is not working correctly,
have the device checked by an expert
immediately.
Filling up saw chain oil
►P. 5, item 7
NOTICE!
Environmental damage!
Since the saw chain oil can penetrate
the environment during operation,
biologically-degradable special veg-
etable-based saw chain oils should
be used.
– Lay device securely with the tank
cover (10) upwards.
– Before opening, clean the tank cover and
the filler neck if necessary.
– Slowly open and remove the tank cover.
– Carefully fill up the saw chain oil. Do not
spill!
– Read the oil level at the inspection
glass (6). The oil stand must be placed
between [MIN] and [MAX].
– Tighten the tank cover by hand.
– If you have spilled any saw chain oil, be
sure to wipe it up.
– Check the oil quantity in the tank.
– Start the device.
– Hold the running saw chain approx. 15
cm over a suitable surface for a time
(15s).
Operation
Safety equipment
The device has several pieces of safety
equipment which reduce the risk of injury
when working:

12
DANGER!
Risk of injury!
The device must only be put into
operation if no faults are found. If any
part of the device is defective, it must
be replaced before the next use.
Chain catcher
The chain catcher serves to catch a torn saw
chain or one which has jumped out of the
guide. Through regular maintenance of the
saw rail and correct and regular tensioning of
the saw chain, accidents of this type can be
prevented.
The rear hand guard
The rear hand guard serves to protect the
hand against a jumped chain and disturbing
branches and twigs.
Check before starting!
Check the safety equipment and the safe
condition of the device.
– Check all parts for their firm fit.
– Check whether there is any leakage.
– Check whether there are visible defects:
broken parts, cracks, etc.
– Check the device for correct chain ten-
sioning.
– Check the function of the chain brake.
Attaching the extension cable
►P. 6, item 8
– Plug the unit plug into the connector of
the extension cable.
– Feed the extension cable through the
strain relief mechanism (13) as shown.
Starting the device
►P. 6, item 9
– Hold the device fast with both hands.
– The hand guard (8) must be folded
towards the back.
– Press the switch-on safety lock (11).
– Press the start button (12).
The device starts up.
Use
Before use, familiarize yourself sufficiently
with the sawing technique for chain saws.
You will find information about this in the
trade literature. We recommend that you
attend suitable training sessions. The notes
here serve only as a complement!
Correct posture
DANGER!
Risk of injury!
Never work on unstable subsurfaces!
Never work above shoulder height!
Never work while standing on a lad-
der!
Do not work bent too far forward!
Only use the device under favourable
weather and site conditions!
– Stand with both legs securely on the
ground.
– Heed obstacles in the work area.
– While you are working, always hold the
device fast with both hands!
Hold the device:
– with the left hand on the handle.
– with the right hand on the handle.
– balanced in a secure position.

13
Here’s how to saw correctly!
DANGER!
Risk of injury!
Always switch the motor off before
you put the device down!
• Search the work area and remove objects
which are in your way.
• When you begin work, check the safety of
the device (►Check before starting! –
p. 13).
• Take the device in both hands as
instructed.
Risk of rebound!
Rebounds occur if the upper edge or tip of
the saw rail touch wood or other hard
objects. The device is thrown with high
energy back and forth, which can cause
extremely severe injuries.
DANGER!
Risk of injury!
When working with the device, dan-
gerous rebounds may occur! Severe
or even fatal injuries can be the
result! Before beginning work with
the device, the chain brake must be
checked to ensure that it is function-
ing correctly.
Avoid letting the area of the saw rail depicted
on the right touch wood 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. 12).
With less strong rebounds, it can happen that
the chain brake is not triggered automati-
cally. 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 train-
ing and experience of a professional.
Do not perform any work for which
you are not sufficiently qualified!
Thoughtless handling of the device
can cause severe or even fatal inju-
ries!
Before each use
1. Check the chain brake to ensure it is
functioning correctly.
2. Check the rear hand guard for damage.
3. Check the switch-on safety lock and start
button to ensure they are functioning cor-
rectly.
4. Check whether all handles are free of oil.
5. Check whether all parts of the device are
present, firmly attached and undamaged.
6. Check the chain catcher for damage.
7. Check the chain tensioning.
Sawing technique
Pulling sawing
With this technique, sawing occurs with the
underside of the saw rail from above down-
wards. The saw chain thus pushes the device
forwards 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 pre-
ferred sawing technique.
Pushingsawing

14
DANGER!
Risk of injury!
Felling and delimbing work may only
be performed by trained people!
There is a risk of fatal injuries!
1
C
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.
If the user does not balance out the force of
the saw chain pushing backwards with his or
her bodily force, there is a danger that only
the tip of the saw rail will make contact with
the wood and there will thus be a rebound
(►Risk of rebound! – p. 14).
Felling a tree
B
45°
A
45°
B
Before beginning the felling work, make sure
that:
• there are no people or animals in the fell-
ing area of the tree.
• there is an obstacle-free escape route for
each participant. A retreat occurs diago-
nally counter to the felling direction.
• the area around the trunk is free of obsta-
cles (risk of stumbling!).
• the next workplace is at least two and a
half tree lengths away. Before felling, the
felling direction of the tree must be
checked and it must be ensured that
there are no objects, people or animals in
a distance of 2 1/2 tree lengths.
2
The felling of a tree occurs in two steps:
1. Notch the trunk by approximately one-
third of its diameter on the felling direc-
tion side.
2. On the other side, make the felling cut,
which must be somewhat higher than the
felling notch (approx. 3-5 cm).
DANGER!
Risk of injury!
Never saw the tree trunk completely
through. The area serves as a "hinge"
and ensures a defined felling direc-
tion.
DANGER!
Risk of injury!
When felling, stand only to the side of
the tree to be felled! There is a risk
of fatal injuries!
Trunks lying flat on the ground
– Cut into the trunk halfway, then turn over
and saw through from the opposite side.
NOTICE!
Device damage!
Make sure that the saw rail does not
touch the ground while you are saw-
ing through the trunk!
Propped-up trunks
We recommend that you place trunks to be
sawed through on sawhorses. If this is not
possible, the trunk should be lifted with the
help of supporting branches and placed over
trestles.

15
DANGER!
Risk of injury!
Do not saw any trunks under tension!
Splintering wood or a twisted saw rail
can cause extremely severe injuries!
DANGER!
In the interest of your own safety!
Only perform the maintenance work
described here yourself.
Any other work, especially motor
maintenance and repairs must be
performed by a trained professional.
Improper work can cause damage to
the device and thus also injuries.
DANGER!
Risk of injury!
Before any maintenance or cleaning
work:
– Pull out the plug.
– Let the device cool down.

16
DANGER!
Danger of death!
A worn or improperly sharpened
chain can cause rebounds. Severe or
even fatal injuries can be the result!
Note:
Special tools are required to sharpen
the saw chain; these guarantee that
the cutting of the chain occurs at the
correct angle and the correct depth.

**) The specified vibration emission value was
measured in accordance with a normed test
procedure and can be used in order to compare
one tool with another. The specified vibration
emission value can also be used for an intro-
ductory evaluation of the exposure. The vibra-
tion emission value may fluctuate from the
specified value during actual use of the power
tool. These fluctuations will depend on the way
in which the power tool is used. Try to keep
vibrations to a minimum. One method of reduc-
ing the vibration load is, for example, limiting
the length of time you work with the tool. All
parts of the operating cycle must be taken into
account for this purpose (for example, also
including times in which the power tool is
switched off and times in which it is switched
on, but is running without load).
Appropriate chain oil
NOTICE!
Risk of damage to the device!
Under no circumstances should you
use old oil to grease the saw chain!
This can cause damage to the oil
pump, saw rail and chain!
Use only special saw chain oils with good
adhesion properties. Since the saw chain oil
can penetrate the environment during opera-
tion, biologically-degradable special vegeta-
ble-based saw chain oils should be used.
