4. Make the felling cut on the opposite side to the initial
notch and slightly higher than the notch. As the felling cut
gets close to the notch cut, the tree will begin to fall.
5. Remove the saw from the cut, stop the engine with the
on/off switch (18), put the saw down and leave the area
along the retreat path.
Limbing
Limbing is the process of
removing the branches from
a fallen tree.
Check the direction in which a branch will bend before
cutting it. Always cut on the opposite side to the bending
direction so that the guide bar is not pinched in the cut.
For large limbs that cannot be removed in one cut, make
an initial cut from the bent side and finish by sawing from
the opposite direction. Do not remove limbs that are
supporting the fallen tree on the ground until the tree has
been cut into lengths.
WARNINGS. Always keep a balanced stance. Do not stand
on the log. Be alert to the fact that the log may roll over.
When working on a slope, always stand on the uphill side
of the log.
Bucking
Bucking is cutting a log into
lengths for easier handling.
To saw a log lying on the ground,
first saw halfway, then roll the log
over and cut from the opposite
side. To saw the end of a log
supported off the ground, first
saw up from the bottom one-third through the log then finish
by sawing down from the top. To saw a log in the middle of
two supports holding it off the ground, first saw down from
the top one-third through the log then finish by sawing up
from the bottom.
CAUTION. Avoid cutting into the ground as this will very
quickly dull the saw chain.
Pruning
Pruning is the removal of a limb
or branch from a standing tree.
WARNINGS. Do not use an
unstable foothold or ladder. Do
not overreach. Do not saw above
shoulder height. Always use both
hands to hold the saw.
First cut up from the bottom and finish down from the top.
Maintenance
Note. Before cleaning your chainsaw or carrying out any
maintenance procedure, make sure that the engine is off
and is cool. Disconnect the spark plug to prevent
accidental starting.
Maintenance to be preformed after each use
1. Loosen the filter cover knob (11) and remove the filter
cover (10).
2. Remove the air filter (7).
3. Split the air filter into its two
halves and clean the mesh.
Dry particles can be removed
by tapping on a hard surface.
More stubborn dirt may
require washing out the filter
with petrol or using an air
compressor.
4. Re-assemble the two halves
and replace the airfilter, filter
cover (10) and knob (11).
5. Take off the guide bar (1)
and maintain it as follows,
remove any sawdust from the
groove in the guide bar.
