6. Reset the ridged bumper at a low point when cutting thicker logs by pulling the
product slightly backwards and reposition at lower level to continue sawing. Do not
remove the product completely from the wood.
7. Do not force the saw chain while cutting, let the chain do the work.
8. Do not operate the product with arms fully extended or attempt to saw areas which
9. Optimum sawing is achieved if the chain speed remains constant during cutting.
10. Be careful when reaching the end of the cut. The weight of the product may change
unexpectedly as it cuts free from the wood. This can cause accidents to the legs
and feet. Always remove the product from a wood cut while the product is running.
11. Check the chain tension and oil feeding regularly.

1. When bucking and felling operations are being performed by two or more persons
at the same time, the felling operations should be separated from the bucking
operation by a distance of at least twice the height of the tree being felled. Trees
should not be felled in a manner that would endanger any person, strike any utility
line or cause any property damage. If the tree does make contact with any utility
2. The product operator should keep on the uphill side of the terrain as the tree is
likely to roll or slide downhill after it is felled.
3. An escape path should be planned and cleared as necessary before cuts are
started. The escape path should extend back and diagonally to the rear of the
expected line of fall.
4. Before felling is started, consider the natural lean of the tree, the location of larger
branches and the wind direction to judge which way the tree will fall.
5. Remove dirt, stones, loose bark, nails, staples and wire from the tree.
Make the notch (B) 1/3 the diameter of the tree, perpendicular to the direction of falls.
saw chain or the guide bar when the second notch is being made.
Make the felling back cut (A) at least 50 mm higher than the horizontal notching cut.
Keep the felling back cut parallel to the horizontal notching cut. Make the felling back
cut so enough wood is left to act as a hinge. The hinge (C) wood keeps the tree from
twisting and falling in the wrong direction. Do not cut through the hinge.
As the felling gets close to the hinge, the tree should begin to fall. If there is any chance
that the tree may not fall in desired direction or it may rock back and bind the saw chain,
stop cutting before the felling back cut is complete and use wedges of wood, plastic or
aluminum to open the cut and drop the tree along the desired line of fall.
When the tree begins to fall
remove the product from the cut, switch off and put the
product down then use the retreat path planned. Be alert for overhead limbs falling and
watch your footing.
