To use a spiked bumper
A spiked bumper holds the wood as you cut. The spiked
bumper is a pivot between the engine body and the
guide bar.
1. Put the lower end of the spiked bumper at the
correct felling hinge width.
2. Push against the front handle with your left hand and
lift the rear handle with your right hand.
3. Cut until you get the correct felling hinge width.
Note: The felling hinge must have an equal
thickness.
4. Cut more than half of the diameter and then put the
felling wedge into the saw cut.
To fell a tree
1. Remove dirt, stones, loose bark, nails, staples and
wire from the tree.
2. Make a notch 1/3 the diameter of the tree,
perpendicular to the direction of the fall. (Fig. 56)
3. Make the lower horizontal notch cut. This will prevent
either the saw chain or the guide bar from being
pinched when the second notch is made.
4. Make the felling back cut (X) at least 50 mm (2 in)
higher than the horizontal notching cut. Keep the
felling back cut parallel to the horizontal notching cut
so enough wood is left to act as a hinge. Do not cut
through the hinge. The hinge wood keeps the tree
from twisting and falling in the wrong direction. (Fig.
57) (Fig. 58)
5. As the felling back cut nears the hinge, the tree
starts to fall. Make sure that the tree can fall in the
correct direction and not rock rearward and pinch the
saw chain. Stop the cut before the felling back cut is
complete to prevent this. Use wedges of wood,
plastic or aluminium to open the cut and let the tree
fall along the necessary line of fall. (Fig. 59)
6. When the tree begins to fall, remove the product
from the cut, stop the engine, put the product down,
then use the retreat path planned. Be alert for
overhead limbs falling and watch your footing. (Fig.
60)
To limb a tree
1. Use larger limbs to hold the log off the ground.
2. Remove small limbs in one cut. (Fig. 61)
3. Cut branches that have tension from the bottom to
the top to prevent pinching the saw chain or the
guide bar.
To buck a log
CAUTION: Do not let the saw chain touch
the ground.
