
Determine the direction of the cut, taking into account the wind, the slope of the tree, the location of heavy branches, ease
of work after felling and other factors (Fig. (Rys.) 15).

By clearing the area around the tree arrange a good escape route.

Make an incision to one-third the depth of the tree (Fig. (Rys.) 16) on the side of the tree where the tree is to be laid.

Make a cut on the opposite side of the cut, at a level slightly higher than the cut.
WARNING!
When cutting down a tree, warn people who may be nearby about potential danger.
CUTTING AND HEWING
Before starting work, assess the direction of the distribution of forces (stresses) inside the entire log. Always end the cut on the
opposite side of the log bending direction to prevent cutting guide jam.

A tree lying on the ground (Fig. (Rys.) 17): Cut down halfway, then turn the log and cut from the other side.

Tree placed on supports (Fig. (Rys.) 18): In area A, cut from the bottom up to one third of the depth and finish cutting from
the top down. In area B, cut from top to bottom to one third of the depth and finish cutting from the bottom up.

Cutting off the branches of a felled tree (Fig. (Rys.) 19): First check which way the branch is bent. Then make the first cut
from the bend side and finish cutting from the other side. If the branch is bent like at (Fig. (Rys.) 19) - cut from the bottom
up, finish cutting from the top down.

Cutting off the branches of a standing tree (Fig. (Rys.) 20).
Attention! First cut the branch down to approximately ½ in diameter, then cut the branch from above.
WARNING!
Always ensure good foot support. Do not stand on tree logs. Watch out for the rolling of the cut log.
Be careful of springing the branch being cut off.
Do not use the saw on an unstable surface or ladder. Do not work with arms outstretched. Do not cut above shoulder height. Always
hold the chain saw with both hands.
MAINTENANCE
The rules for safe maintenance of the device are described in this manual in the section "Maintenance and storage" in the chapter
"Detailed safety rules for petrol saws".
WARNING!
Before cleaning, inspecting or repairing the device, make sure that the engine is switched off and is not hot. Disconnect the spark
plug to prevent the petrol saw from being switched on accidentally.
AIR FILTER CLEANING
A dirty air filter increases fuel consumption and reduces the efficiency of an internal combustion engine. The air filter should be
cleaned as needed, at least every 5 hours of operation of the saw. Sawdust on the filter surface can be removed with a brush. To
clean the filter from the inside, use compressed air.
To reach the air filter, unhook the tabs 1 (Fig. (Rys.) 21) and remove the air filter cover 2 (Fig. (Rys.) 21).
Then unscrew the wing nut holding the air filter 1 (Fig. (Rys.) 22) and remove the air filter 2 (Fig. (Rys.) 22). The air filter should be
disassembled, washed with gasoline and dried, and replaced if necessary.
CYLINDER RIBBING
Dust accumulating on the cylinder fins may cause the saw engine to overheat, therefore the cylinder fins should be inspected and
cleaned periodically during air filter maintenance.
MAINTENANCE OF THE SPARK PLUG
To ensure proper operation of the engine, check the condition of the spark plug, check its cleanliness and the gap, which should be
0.5-0.7 mm. Use original TORCH L8RTF spark plugs. Always do the following with the engine off:
