Fill the chain oil tank (Fig.34 / M )) to 80% with chain
oil.

Oil Supply Control
Always make sure that the automatic oil system is
working properly. Always ensure the oil tank is full.
During sawing work, the guide and the chain must al-
ways be sufficiently oiled to reduce friction with the
chain bar.
The chain bar and the chain must never be without
oil. If you operate the chain dry or with too little oil, the
cutting performance will decrease, the service life of
the chain bar will reduce, the chain will become blunt
quickly and the guide will wear rapidly owing to over-
heating. You can detect a lack of oil from smoke de-
velopment or the guide changing colour.
To check the chain lubrication keep the chain on a
piece of paper and give full throttle for a few seconds.
On the paper the quantity of oil can be checked.The
saw chain must always throw off a little oil. After a few
seconds, a slight oil trace must be visible.
Make sure that there is always enough oil in the tank
because chain lubrication is always on.

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 position
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 correctly
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 fall-
en 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 ar-
ea.
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
• Saw until the branch breaks. The risk of injury on
• Finally, remove with a clean cut from the top of the
possible!
• Thus, the damage to the tree are kept as low as
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 notice-
able as with traditional chainsaws.
Always still keep a firm grip and a good level to main-
tain control of the tool in doubt.
The most common effects are:
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.
