Maintenance - Honda UMK425E1 Manuel Du Propriétaire

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.

MAINTENANCE

REPLACING THE LINE
1. Press the lugs [2] located on either side of
the head to open it.
2. Extract the reel and remove
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.
3
5. Secure the ends in the two
1
opposite notches [3] (leaving
2
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:
C13
• Always use a line of the diameter recommended in the technical
specifications.
D2 D3
SAFETY
• 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.
3
Never replace the nylon line with a line of a different material,
1
such as steel wire.
2
To avoid severe personal injury, disconnect the spark plug cap
to prevent accidental starting.
Wear heavy gloves to prtect yur hands when replacing the
nylon head.
SHARPENING
3-TOOTH AND 4-TOOTH BLADES
SAFETY
Sharpening is essential to obtain good results. A slightly blunt
cutting attachment can be sharpened with a file.
A grinding wheel should be used if the wear is more severe.
CAUTION:
• In all cases, the cutting attachment must be kept correctly
balanced. If you do not have the required tools or if you think your
cutting attachment may not be properly balanced, contact your
authorized Honda dealer.
Remove the cutting attachment for sharpening and check that it is
not cracked, out of true or bent.
If it is, replace it with a new one.
