Cutting Techniques - EINHELL GC-LC 18/20 Li T Operating Instructions Manual

Hearing protection and protective goggles
Wear a protective helmet with integral face and
hearing protection. This will off er protection
against falling and recoiling branches.
Work safety
•
To ensure that you can work in safety you
must use the tool at a working angle of max.
60°.
•
Never stand under the branch you want to
saw.
•
Use special caution when working with
branches under tension and with splintering
wood.
•
Possible risk of injury from falling branches
and pieces of wood catapulted into the
surroundings!
•
When the tool is in operation, keep other
persons and animals away from the danger
zone.
•
The tool is not protected from electric shock
through contact with high-voltage cables.
Keep a minimum distance of 33 ft. (10 m)
from live cables. Electric shock can cause
fatal injury.
•
When working on slopes always stand to the
upper or left or right side of the branch you
want to cut.
•
Hold the tool as close as possible to your
body. This will help you to keep your balance.

Cutting techniques

•
When removing branches, hold the tool at an
angle of max. 60° to the horizontal to avoid
being hit by a falling branch (Fig. 20).
•
Start with the bottom branches on the tree.
This will make it easier for the cut branches to
drop.
•
After completing a cut, the weight of the saw
will abruptly increase for the operator as the
saw is no longer supported by the branch.
This can result in you losing control over the
saw.
•
Remove the saw from the cut only with the
saw chain still running. This will prevent the
saw from getting jammed.
•
Never cut with the tip of the saw.
•
Never cut into the bulging branch collar. This
will prevent the tree from healing.
Sawing off smaller branches (Fig. 21):
Place the contact surface of the saw onto the
branch. This will prevent the saw from making
jerky movements when you begin a cut. Exerting
slight pressure, guide the saw from the top to the

bottom through the branch.
Sawing off large and long branches (Fig. 22):
Carry out a relief cut when working on large
branches.
Start by sawing through 1/3 of the branch
diameter (section 1) from the bottom to the top
with the top side of the bar. Then saw towards the
fi rst cut (section 2) from the top to the bottom with
the bottom side of the bar. Saw off long branches
in several steps to keep control over the impact
location.
Kickback
The term "kickback" describes what happens
when the running pole chain saw suddenly kicks
upward and backward. Usually this is caused
by contact between the tip of the bar and the
workpiece or by the saw chain becoming trapped.
In the event of kickback, large forces occur
suddenly and violently. As a result, the pole chain
saw usually reacts uncontrollably. This can often
result in very serious injuries to the worker or
persons in the vicinity. The risk of kickback is at
its greatest when the saw is positioned for a cut
in the region of the tip of the bar, as the leverage
eff ect is greatest there. It is therefore safest to
position the saw as fl at as possible.
Warning!
•
Make sure that the chain tension is always
correctly adjusted.
•
Only use pole chain saw that is in perfect
working order.
•
Only work with a saw chain that has been
properly sharpened in accordance with the
instructions.
•
Never cut with the upper edge or the tip of the
bar.
•
Always hold the pole chain saw firmly with
both hands.
Cutting wood which is under tension
Special care is required when cutting wood which
is under tension. Cutting wood which is under
tension can release the tension, causing the
wood to react out of control. In the worst case this
can result in severe and even fatal injuries. This
type of work must be performed only by specially
trained persons.
