Cutting techniques

•
When removing branches, hold the equip-
ment at an angle of max. 60° to the horizontal
to avoid being hit by a falling branch (Fig. 27).
•
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. 28):
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 larger and longer branches
(Fig. 29):
Carry out a relief cut when working on larger
branches.
Start by sawing through 1/3 of the branch diame-
ter (a) from the bottom to the top with the top side
of the cutter rail. Then saw towards the fi rst cut (b)
from the top to the bottom with the bottom side of
the cutter rail.
Saw off longer branches in several steps to keep
control over the impact location.
Kick-back!
The term "kickback" describes what happens
when the running chainsaw suddenly kicks up-
ward and backward. Usually, this is caused by
contact between the tip of the cutter rail and the
workpiece or the saw chain becoming trapped.
In the event of kickback, large forces occur sud-
denly and violently. As a result, the chainsaw
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 cutter rail, as the leverage eff ect is
greatest there. It is therefore safest to position the
saw as fl at as possible.

Important!

•
Make sure that the chain tension is always
correctly adjusted.
•
Only use a chainsaw if it 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
cutter rail.
•
Always hold the chainsaw firmly with both
hands.
Cutting wood which is under tension
Special care is required when cutting wood which
is under tension. Wood which is under tension
from which it is released by cutting may in some
cases react completely unpredictably and un-
controllably. In the worst case this could result in
extremely severe or even fatal injuries. This type
of work must only be performed by persons who
have been specially trained.
8. Working with the hedge trimmer
mounting kit
•
Check that the cutters work properly. The
twin-bladed cutters rotate in opposite direc-
tions, thus guaranteeing high cutting perfor-
mance and smooth operation.
•
Take care to maintain a steady foothold and
hold the equipment firmly in both hands away
from your body. Before you switch on, make
sure that the equipment is not touching any
objects.
Work practice
•
A hedge trimmer can be used to cut shrubs
and bushes as well as hedges.
•
To obtain the best cutting results, hold the
hedge trimmer so that the cutter teeth are
at an angle of approx. 15° in relation to the
hedge (see Fig. 30).
•
The twin-bladed cutters rotate in opposite
directions, thus enabling cutting in both direc-
tions (see Fig. 31).
•
It is recommended to tie a guide line of string
or the like along the hedge so that you cut the
hedge to a level height. Cut off all branches
which protrude beyond the guide line (see
Fig. 32/33).
•
Cut the sides of the hedge with curve-shaped
movements from the bottom up (see Fig. 34).
