maximum speed for the whole time. Allow the chain to cut wood. Press down the saw lightly. Stop pressing the saw at the end of
the cut to avoid losing control over the tool. When the cutting has been finished release the throttle lever (8) and allow the engine
to run idle. Switch off the engine before putting the chain saw away. Keeping high speed of the engine when not cutting wood
causes unnecessary losses and wear of parts.
4.11. Protection against recoil.
Recoil is movement of the guide bar of the chain saw up and/or back, which happens when the part of the chain on the guide
bar tip encounters an obstacle. Ensure the processed material is firmly fixed. Use clamps to fix the material. Hold the chain
saw with both hands when starting up and during operation. During recoil the chain saw cannot be controlled and the chain is
loosened. Incorrectly sharpened chain increases risk of recoil. Do not cut above level of your shoulders.
Avoid cutting with guide bar tip, it may cause sudden recoil - to the back and up. Always use complete safety equipment and
appropriate working clothes when operating the chain saw. Disassembly of protections, inappropriate operation, maintenance,
improper guide bar or chain replacement may contribute to increase of risk of body injury in case of recoil. Never modify the saw
in any way. By using modified chain saw, the user looses all warranty rights. Warranty voids also when the chain saw is used in
accordingly to information contained in this manual.
4.12. Cutting pieces of wood.
When cutting wood follow guidelines for safety of work and do as follows: Ensure the wood piece cannot be moved. Use
clamps to fix short pieces of material before cutting. Cut wood or wood-like materials only. Before cutting ensure the chain saw
will not come into contact with stones or nails, as it could cause pulling the saw out and damage to the chain. Avoid situations
when working saw might touch wired fence or ground. When cutting branches support the saw as much as possible and do not
cut with the tip of the guide bar. Watch out for obstacles such as protruding stumps, roots, hollows and holes in the ground, as
they may be cause of an accident.
4.13. Felling a tree.
Felling trees require great experience. Do not perform activities for which you are not qualified! Define the tree fall line.
Consider wind, lean of the tree, location of heavy branches, complexity of work after tree fall and other factors. When tidying
area around the tree remember to ensure proper ground grip and escape path to use when the tree falls. Predict and tidy up
two escape paths at 45° angle, counting from the line opposite to expected line of the tree fall. There must be no obstacles on
these paths.
The cutting is done by making three notches. Steering is done first notch, including upper and lower notch, and then ends
with the felling notch. By proper placement of the three notches can be controlled direction. Make an initial upper notch at an
angle, one third of the trunk diameter deep. Make a horizontal notch lower, to join the top. Perform overthrown notch horizontally
from the opposite side of the guide and a little higher than lower surface of the notch. Insert wedges on time to avoid pinching of
the saw chain. Fell the tree by driving a wedge rather than cutting through the whole trunk.
