Sawing; Felling A Tree - Hitachi CS40EM Bedienungsanleitung

7. Sawing

WARNING
•
•
• When completing a cut, be ready to hold
up the unit as it breaks into clear, so it will
not follow through and cut your legs, feet or
body, or contact an obstruction.
• Always keep the spiked bumper face to a
tree, because the chain may suddenly be
drawn into a tree.
• It is not necessary to force the saw into the
cut. Apply only light pressure while running
the engine at full throttle.
• When the saw chain is caught in the cut, do
not attempt to pull it out by force, but use a
wedge or a lever to open the way.
GUARD AGAINST KICKBACK
• This saw is equipped with a chain
brake that will stop the chain in
the event of kickback if operating
properly. You must check the chain
brake operation before each us-
age by running the saw at full the

Before proceeding to your
job, read the section "For
Safe Operation". It is recom-
mended to first practice saw-
ing easy logs. This also helps
you get accustomed to your
unit.
Always follow the safety
regulations. The chain saw
must only be used for cutting
wood. It is forbidden to cut
other types of material. Vibra-
tions and kickback vary with
different materials and the
requirements of the safety
regulations would not be re-
spected. Do not use the chain
saw as a lever for lifting, mov-
ing or splitting objects. Do
not lock it over fixed stands.
It is forbidden to hitch tools
or applications to the PTO
other than those specified by
the manufacturer.
throttle for I -2 seconds and push-
ing the front hand guard forward.
The chain should stop immediately
with the engine at full speed. If the
chain is slow to stop or does not
stop, replace the brake band and
clutch drum before use.
• It is extremely important that the
chain brake be checked for proper
operation before each use and
that the chain be sharp in order to
maintain the kickback safety level
of this saw. Removal of the safety
devices, inadequate maintenance,
or incorrect replacement of the bar
or chain may increase the risk to
serious personal injury due to kick-
back.

FELLING A TREE

Felling direction
Notch cut
1. Decide the felling direction considering the wind,
lean of the tree, location of heavy branches, ease
of completing the task after felling and other fac-
tors.
2. While clearing the area around the tree, arrange a
good foothold and retreat path.
3. Make a notch cut one-third of the way into the tree
on the felling side.
4. Make a felling cut from the opposite side of the
notch and at a level slightly higher than the bottom
of the notch.
WARNING
• When you fell a tree, be sure to warn neighbor-
ing workers of the danger.
Bucking and Limbing
WARNING
• Always ensure your foothold. Do not stand on
the log.
• Be alert to the rolling over of a cut log. Especial-
ly when working on a slope, stand on the uphill
side of the log.
• Follow the instructions in "For Safe Operation"
to avoid kickback of the saw.
Before starting work, check the direction of bending
force inside the log to be cut. Always finish cutting
from the opposite side of the bending direction to pre-
vent the guide bar from being caught in the cut.
