•
Hold the tool as close as possible to your
body. This will help you to keep your balance.
Sawing 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. 17).
•
Start with the bottom branches on the tree.
This will make it easier for the cut branches
to drop.
WARNING! Never stand underneath the branch
you are sawing – always keep out of the range
of falling branches! – Branches landing on the
ground could bounce up again – Danger of in-
jury
•
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 small branches (Fig. 18):
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. 19):
Carry out a relief cut when working on large bran-
ches.
Start by sawing through 1/3 of the branch diame-
ter (a) from the top to the bottom 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 long branches in several steps to keep
control over the impact location.
Kickback
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 by the saw chain becoming trapped.
In the event of kickback, large forces occur sud-
denly and violently. As a result, the chainsaw
Anl_GC_HC_90-2046_T_SPK13.indb 25
GB
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.
Warning!
•
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 rail.
•
Always hold the chainsaw firmly with both
hands.
Cutting wood which is under tension
Danger!
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.
8. Maintenance
Keep the tool, the cutter set and the cutter set
guard in good working condition. Poor mainte-
nance can result in damage to the tool and in very
serious injuries.
There are no other parts inside the tool which re-
quire maintenance.
8.1 Replacing the saw chain and the cutter
rail
The cutter rail needs to be replaced if the guide
groove of the cutter rail is worn. Proceed as de-
scribed in the section "Fitting the cutter rail and
saw chain".
Use only saw chains and cutter rails approved by
the manufacturer. These are listed in section 4
"Technical data" or are available as accessories
(see section 10.3 "Ordering spare parts"). The
use of spare parts which are not approved by the
manufacturer could result in very serious injuries.
