5. Safety Devices on your Chain brake (continued)
CaUTIoN: No buttons should be pressed when the chain
brake is released (hand protection pulled back in the direction
of the handle and locked).
always ensure before starting the chainsaw that the hand protec-
tion (5) is locked in the operating position. To do this, pull back the
hand protection in the direction of the handle.

5.2. Rundown brake

In accordance with the latest regulations, this chainsaw is equipped with
a mechanical rundown brake. This brake is connected to the chain brake
and stops the running chain after the chainsaw has been switched off.
It is activated by releasing the ON/OFF switch. The rundown brake
avoids injuries through the coasting of the chain.

5.3. Chain catch bolt

18
This chainsaw is fitted with a chain catch bolt (18). If the chain breaks
when the saw is in operation, the chain bolt will catch the loose chain end
and thus prevent injury to the operator's hand.
6. Instructions on Working Properly with the
Chainsaw

a) felling a Tree

When bucking and felling operations are being performed by two or more
persons, at the same time, the felling operation should be separated
from the bucking operation by a distance of at least twice the height
of the tree being felled. Trees should be felled in a manner that would
endanger any person, strike any utility line, the utility company should
be notified immediately.
The chainsaw operator should keep on the uphill side of the terrain as the
tree is likely to roll or slide downhill after it is felled.
A retreat path should be planned and cleared as necessary befor cuts are
started. The retreat path should extend back and diagonally to the rear of
the expected line of fall as illustrated in Figure 10.

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.
Remove dirt, stones, loose bark, nails, staples, and wire from the tree
where felling cuts are to be made.

b) Notching Undercut

Make the notch 1/3 the diameter of the tree, perpendicular to the direc-

tion of fall as illustrated in 11. Make the lower horiziontal notching cut first.
This will help to avoid pinching of either the saw chain or the guide bar
when the second notch is being made.

c) felling back Cut

Make the felling back cut at least 2 inches (50.8 mm) higher than the
horizontal notching cut as illustrated in Figure 11. 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 wood keeps the tree from
twisting and falling in the wrong direction. Do not cut through the hinge.
As the felling cut gets close to the hinge the tree should begin to fall. If
there is any chance that the tree may not fall in the 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 chainsaw from the cut, stop the
motor, put the chainsaw down, then use the retreat path planned. Be alert
for overhead limbs falling and watch your footing.

d) limbing a Tree

Limbing is removing the branches from a fallen tree. When limbing,
leave larger lower limbs to support the log off the ground. Remove the
small limbs in one cut as illustrated in Figure 12. Branches under tension
should be cut from the bottom up to avoid binding the chainsaw.

e) bucking a log

Bucking is cutting a log into lengths. It is important to make sure your
footing is fim and your weigth is evenly distributed on both feet. When
possible, the log should be raised and supported by the use of limbs, logs
or chocks. Follow the simple directions for easy cutting.
