Precautions for Saw procedure
Never stand under the branch you want to saw. Use
special caution when working with branches under
tension and splintering wood. Possible risk of injury
caused by falling branches and catapulting pieces of
wood. In general, it is recommended to set the prun-
ing saw at an angle of 60° to the road.
Keep both hands well with the device during the cut-
ting process and pay you up to an equilibrium posi-
tion and a good level.
• Never try to use your tool with one hand. The loss
of control of your tool can cause serious injury or
death. Never work on a ladder, a tree branch or
other unstable surfaces.
• Never cut with the upper edge or the tip of the cut-
ter bar.
• Make sure that the chain tension is always cor-
rectly adjusted.
• Practice for guiding the device slight pressure, but
you do not overload the motor.
Clear the work area before cutting interfering branch-
es and undergrowth. Then you create a retreat area,
far from the spot where the cut branches fall on, and
remove any obstacles there. Keep the work area
clean, remove the cut branches immediately. Pay at-
tention to your point, wind direction and the possible
direction of fall of the branches. Be prepared that
fallen branches can strike back. Place all other tools
and equipment at a safe distance from the branches
to be cut, but not in the retreat area.
Always observe the condition of the tree.
Look for rot and decay in the roots and branches.
If they are rotten inside, they can break off and fall
down unexpectedly during cutting.
You could also attend by fractured and dead branch-
es out, which is solved by the shake and fall on you.
For very thick or heavy branches you first make a
small incision below the branch before you work from
the top down to avoid chipping.
Basic cutting technique
Heavy branches break off easily when sawing. They
tear long strips of bark away from the trunk, which
damages the tree sustainably. The following section
technique can significantly reduce this risk:
• Saw the first branch about 10 cm from the trunk.
• Put in about 15 cm from the base of the top of a
further section.

possible!
• Saw until the branch breaks. The risk of injury on
the trunk is no.
• Finally, remove with a clean cut from the top of the
trunk along the remaining.
• Thus, the damage to the tree are kept as low as
possible, we recommend the interface additionally
to seal with grafting wax.
Hazards by reactive forces
Reactive forces occur during operation of the saw
chain. The forces which are applied to the wood are
against the operator. They occur when the moving
chain comes into contact with a fixed object such as
a branch or is pinched. These forces can lead to a
loss of control and injury.
Understanding the origin of these forces can help
you to avoid the scare and the loss of control. This
saw is designed to make the return effects are not as
noticeable as with traditional chain saws.
Always still keep a firm grip and a good level to main-
tain control of the tool in doubt.
The most common effects are:
• setback
• recoil,
• retreat
Kickback
The setback can occur when the moving saw chain
meets at the upper quarter of the guide rail on a solid
object or is pinched.
The cutting force exerted on the chain from the saw,
a rotational force in the opposite direction to the
chain travel. This leads to an upward movement of
the guide rail.
Avoid kickback
The best protection is to avoid situations that lead to
setbacks.
1. Keep the position of the upper guide rail always
2. Leave this place never come into contact with an
3. Cut only one branch at a time.
Withdrawal
The withdrawal occurs when the chain on the under-
side of the bar suddenly stuck because it is jammed
or encounters a foreign object in the wood. The chain
then pulls the saw forward. The withdrawal often
happens when the chain is not running at full speed
when in contact with the wood.
Avoid withdrawal
Be aware of the forces and situations that can lead
to jamming of the chain on the underside of the bar.
in mind.
object. Cut anything with it. Be especially careful
near wire fences and cutting small, hard knots, in
which the chain can easily pinch.
