CAUTION!
Comply with all accident prevention measures laid down by the relevant trade associations
and authorities and recommended by insurers.
Do not undertake any changes whatsoever to the hedge trimmer, because this would put your
safety at risk.
The operator may carry out only the maintenance and repair tasks described in these instructions for
use. All other maintenance work must be carried out by authorised maintenance personnel.
Use only original replacement parts and original accessory parts which you have obtained from authori-
sed solo by AL-KO service centres.
The use of unapproved accessory parts and tools creates an increased risk of accidents and injuries. For
personal injury and/or material damage caused by the use of unapproved replacement and/or accessory
parts, solo by AL-KO accepts no liability.
Sharpening the knives
If the knives have become blunted, and no longer cut
well, sharpen the positions on the blades which are
cross-hatched in the diagram (20-3). Do not sharpen the
contact (slide) surfaces of the upper and lower knives.
(20-1) Flat grinders
(20-2) Cutting cross-section
Switch off the motor, disconnect the the spark plug
lead, and ensure that the cutting blade and the knife
are secured before you grind the knives.
Wear gloves, safety spectacles, etc.
Do not grind off too much material. That would re-
move the hardened layer, and the knives would be-
come blunt very quickly when used.
Resetting the separation between upper and lower knives
Grind the upper/lower knives. If you do not obtain a clean
cut, even though the knives are sharp enough, set the
distance between the knives as follows:
1 Loosen the bolts in order to remove the cutting blade
from the machine.
Loosen the nut (21-1)by means of a ring or open-ja-
2
wed spanner.
Slightly tighten the holding bolt (21-2) by means of a
3
Torx spanner, until you feel resistance, and then loo-
sen the holding bolt again by a quarter-turn.
