Sharpening The Saw Chain; Replacing The Power Cable - EINHELL GC-EC 7520 T Originalbetriebsanleitung

Kickback
The term „kickback" describes what happens
when the running electric pole pruner sudden-
ly kicks upward and backward. Usually this is
caused by contact between the tip of the cutter
rail and the workpiece or by the saw chain be-
coming trapped. In the event of kickback, large
forces occur suddenly and violently. This usually
results in the electric pole pruner reacting out of
control.
Warning!
•
Make sure that the chain tension is always
correctly adjusted.
•
Only use an electric pole pruner that is in per-
fect 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 electric pole pruner firmly
with both hands!
Cutting wood which is under tension
Danger!
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. Maintenance
There are no other parts inside the equipment
which require maintenance.
To keep the tool in good working order, carry
out regular maintenance in accordance with the
following instructions. Use only the accessories
and spare parts approved by the manufacturer,
Details can be found in section 10.3 "Ordering
spare parts". Incorrect maintenance and the use
of non-approved accessories or spare parts can
result in very serious injuries.

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. Unscrew the ad-
apter plate (Fig. 2 / Item 13a) from the old cutter
rail and screw it on the new cutter rail.
Proceed as described 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.
8.2 Checking the automatic chain lubrication
You should check the operation of the automa-
tic chain lubrication system on a regular basis
in order to guard against overheating and the
damage this can cause to the cutter rail and the
chain. Point the tip of the cutter rail at a smooth
surface (a board or a cut tree face) and allow the
electric pole pruner to run. If you see a growing oil
stain on the smooth surface, the automatic chain
lubrication system is working properly. If there is
no clear trace of oil to be seen, please refer to the
corresponding instructions in the section "Troub-
leshooting". If the information contained there fails
to help, please contact our service department or
a similarly qualifi ed workshop.
Warning! Do not actually touch the surface with
the tip of the cutter rail when performing this test.
Keep a safe distance (approx. 20 cm).

8.3 Sharpening the saw chain

Working eff ectively with the electric pole pruner is
possible only if the saw chain is in good condition
and sharp. This also reduces the risk of kickback.
The saw chain can be re-sharpened by any dea-
ler. Do not attempt to sharpen the saw chain your-
self unless you have the necessary special tools
and experience.

9. Replacing the power cable

Danger!
If the power cable for this equipment is damaged,
it must be replaced by the manufacturer or its
after-sales service or similarly trained personnel
to avoid danger.
