stacles 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 branch-
es. 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:
- 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.
- 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 tra-
ditional chainsaws. Always still keep a firm grip and a good level to maintain control of the
tool in doubt.
The most common effects are:
- kickback
- 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 move-
ment of the guide rail.
- Avoid kickback:
The best protection is to avoid situations that lead to kickbacks.
1. Keep the position of the upper guide rail always in mind.
2. Leave this place never come into contact with an object. Cut anything with it. Be es-
pecially careful near wire fences and cutting small, hard knots, in which the chain can
easily pinch.
3. Cut only one branch at a time.
Withdrawal
The withdrawal occurs when the chain on the underside of the bar suddenly stuck because it
is jammed or encounters a foreign object in the wood. The chain then pulls the saw forward.
