Recoil
2
When sawing with the underside of the guide rail - fore-
hand cut - the chainsaw can be pulled suddenly towards
the sawn object if the saw chain jams or hits a solid ob-
ject in the wood.
 To avoid pulling in, always set the bucking spikes
securely onto the wood.
When sawing with the top side of the guide rail - back-
hand cut -the chainsaw can be propelled back towards
the user if the saw chain jams or hits a solid object in the
wood.
 To avoid a recoil:
 Do not pinch the top of the guide rail.
 Do not twist the guide rail in the cut.
Kickback
DANGER
Uncontrolled movements of the chainsaw
Danger of death from incision injuries
Plan the cut before cutting and identify any potential
dangers.
Always hold the chain saw firmly with both hands.
When kickback occurs, the chainsaw is suddenly and
uncontrollably flung in the direction of the user.
A kickback occurs when e.g. the saw chain in the upper
region of the blade guide tip unintentionally encounters
an obstacle or is trapped.
Illustration Q
 Always hold the chainsaw so that the kickback forc-
es can be withstood. Do not let go of the chainsaw.
 Do not bend too far forward when sawing.
 Do not use the chainsaw above shoulder level.
 Always wait until the chain has reached full speed
and saw at full throttle.
 Do not saw with the saw rail tip.
 Insert the guide rail into a started cut only with ex-
treme care.
 Pay attention to the position of the trunk and to forc-
es that can close the cut and jam the saw chain.
 Never saw off several branches at the same time
when pruning.
 Only work with a sharp and properly tensioned
chain.
 Use a chain with a low kickback risk and a guide rail
with a small rail head.
Plan the fall direction and retreat path
DANGER
Falling tree
Danger of death
Tree felling work may only be carried out by trained per-
sons.
When planning the fall direction, note the following:
 The distance to the next workplace must be at least
2.5 tree lengths.
 Do not perform felling in strong wind.
The tree can fall unchecked.
 Determine the direction of fall based on tree growth,
terrain (slope) and weather conditions.
 Always drop the tree into a growth gap, never onto
other trees.
A retreat path must be planned for every worker. Where:
 The retreat path us to be positioned approx. 45 ° di-
agonally opposite the direction of fall.
Illustration R
 Free the retreat path from obstacles.
 Do not place any tools and equipment on the retreat
path.
 When working on a steep slope, plan the retreat
path parallel to the slope.
 When using the retreat path, watch for falling
branches and observe the crown space.
Preparing the work area at the trunk
1. Clean the work area at the trunk of interfering
branches, scrub and obstacles.
Safe stance ensured.
2. Thoroughly clean the root, e.g. with an axe.
Sand, stones and other foreign matter make the
chain blunt.
3. Remove large roots.
a Cut the root vertically.
Illustration S
b Cut the root horizontally.
c Remove the loose root piece from the work area.
DANGER
Falling tree
Danger of death
Tree felling work may only be carried out by trained per-
sons.
1. Make sure nobody will be endangered by the falling
tree. Calls can be overhead due to engine noise.
Only persons occupied with felling may be present
in the felling area.
2. Set the felling notch at right angles to the direction
of fall.
a As close as possible to the ground, make a hori-
zontal cut (sole cut) over approx. 1/3 of the trunk
diameter.
Illustration T
b Make an oblique cut (roof cut) at an angle of ap-
prox. 45-60 °.
3. Set the felling cut.
a Make the felling cut parallel to the sole cut and at
least 50 mm higher.
b Only make the felling cut so far that a break-off
strip at least 50 mm wide remains.
The break-off strip prevents the tree from twisting
and falling in the wrong direction.
As the fell line approaches the break-off strip, the
tree should begin to fall.
4. Stop the felling cut if there is a danger that the tree
will not fall in the desired direction or sway back and
jam the saw chain. Use wedges to extend the cut
and fell the tree in the desired direction.
5. pull the chainsaw out of the cut when the tree starts
to fall.
6. Switch off the device.
7. Lock the chain brake.
8. Lower the chainsaw.
9. Follow the planned retreat route.
DANGER
Uncontrolled movements of chainsaw and sawing
material
Life-threatening incision injuries, injuries caused by
sawed material
Plan the cut before cutting and identify any potential
dangers.
Always hold the chainsaw firmly with both hands
