CUTTING
The nylon line cuts grass cleanly without damaging tree bark and
avoiding the violent impacts that would occur between a rigid cutting
attachment and hard surfaces.
It is, however, recommended not to work too long in such areas in
order to avoid damaging fragile, immature plant, in particular, and to
avoid premature line wear.
Proceed in stages, when trimming, tilting the cutting attachment
slightly.
For larger areas, hold the cutting attachment horizontal and sway it
sideways from right to left and from left to right, alternately.
WITH 3-TOOTH AND 4-TOOTH
BLADE
CAUTION:
• Do not use a blade larger than 255 mm in diameter.
CUTTING
The 3-tooth and 4-tooth grass-cutting blade is especially suitable for
clearing dense and tangled weeds, bushes such as brambles or
wild shrubs with a stem diameter of less than 2 cm.
To trim bushes, lower the cutting attachment from above while
holding it horizontal so as to cut the branches in small pieces.
It is dangerous to use grass-cutting blades on very hard wood
and/or plants with a large stem diameter. Kicking of the cutting
attachment is difficult to control, and can seriously endanger
the operator and cause serious damage to the equipment.

WITH CIRCULAR SAW BLADE
Use of the circular saw blade is only
authorized on UMK435E of UEET type.
CAUTION:
• Never use a saw blade with a diameter in excess of 200 mm. The
circular saw blade is intended to be used for cutting out shrubs,
bushes and small trees whose trunk does not exceed 6 cm in
diameter.
CUTTING
Some blade sectors [1] must
not be used as they will cause
the tool to rebound owing to
the direction of rotation. Tools

NEVER cut with the right half
of the blade. The part to be
used is represented by the
grey area.
For the best results, you must swing your equipment quickly
towards the branch or trunk to be cut. Do not proceed gradually as
engine speed could drop and lead to stalling.
Estimate the height of the items to be cut and where they might
fall.
Ensure that falling pieces will not cause bodily injuries to
persons or property damage.
Make sure the blade is not stuck in the trunk when it falls.

Always cut on the side opposite the fall.

MAINTENANCE

REPLACING THE LINE
1. Press the lugs [2] located on
3
either side of the head to
1 open it.
2. Extract the reel and remove
2
the rest of the nylon line.
3. Prepare 3 metres of 2.7 mm
diameter line and fold it in
half, lengthwise.
4. Place the middle of the line in
the notch [5] in the reel and
coil the wire by turning in the
specified direction.
5. Secure the ends in the two
opposite notches [3] (leaving
an excess of 10 cm of line).
6. Reinstall the reel in its place
and feed the lines through
the two side holes [4].
7. Reinstall the cover.
CAUTION:
• Always use a line of the
diameter recommended in the
technical specifications.
• Poor results would be
obtained if the line diameter is too large as this will result in an
excessive load on the engine, so reducing its performance.
Never replace the nylon line with a line of a different material,
such as steel wire.
To avoid severe personal injury, disconnect the spark plug cap
to prevent accidental starting.
Wear heavy gloves to protect your hands when replacing the
nylon head.
