Oil Supply Control
Always make sure the automatic oiler system is working properly. Keep the oil tank filled with Chain,
Bar and Sprocket Oil.
Adequate lubrication of the bar and chain during cutting operations is essential to minimize friction
with the guide bar.
Never starve the bar and chain of lubricating oil. Running the saw dry or with too little oil will de-
crease cutting efficiency, shorten saw chain life, cause rapid dulling of chain, and lead to excessive
wear of bar from overheating. Too little oil is evidenced by smoke or bar discoloration.
To check the saw chain lubrication, hold the chain saw with the saw chain over a piece of paper and
give a few seconds of full throttle.
The oil quantity can be checked on the paper. The chain must always be thrown off a small amount
of oil. After a few seconds, a light oil trail must be visible.

Use screw (R) to reduce or increase the amount of oil.
Clockwise - oil quantity is reduced (-)
Counterclockwise - oil quantity increases (+)
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 pruning saw at an angle of 60 ° to the road.
Keep both hands well with the device during the cutting 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 cutter 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 branches and undergrowth. Then you create a re-
treat 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 attention 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 branches 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:
