Trimming around trees
When trimming around tree trunks, approach slowly so
that the line does not strike the bark. Walk around the
tree, cutting from left to right. Approach grass or weeds
with the tip of the line and tilt the line spool forwards
slightly.
Warning! Take extreme care during mowing work. When
doing such work keep a distance of 30 meters between
yourself and other people or animals.
Mowing
When mowing, you want to cut all the vegetation down
to the ground. To do this, set the line spool at an angle
of 30° to the right. Place the handle in the required
position. Remember the increased risk of injury to the
user, watchers and animals, and the danger of damaging
property due to objects (for example stones) being
thrown.
Warning! Do not use the equipment to remove objects
from footpaths, etc. The equipment is a powerful tool and
can throw small stones and other objects a distance of
15 meters or more, causing injuries and damage to cars,
houses and windows.
Jamming
If the cutting blade jams as a result of attempting to
cut vegetation that is too dense, switch off the engine
immediately. Remove the grass and scrub from the
equipment before you restart it. Fig. 42
Preventing recoil
When you work with the blade, there is a risk of recoil if
it strikes solid objects such as tree trunks, branches, tree
stumps, stones or the like. This will throw the equipment
backwards in the direction opposite to the rotation of the
tool. This can cause you to lose control of the equipment.
Do not use the blade near fences, metal posts, boundary
stones or foundations.

10. Maintenance

Before performing any maintenance or cleaning work,
always turn off the engine and pull out the spark boot
plug.
1. Do not spray the unit with water. It damages the
engine.
2. Clean the unit with a cloth, hand brush, etc.
Maintenance schedule
12 hours of 24 hours of

Replacing the line spool/cutting line Fig. 35 - 39
1. Dismantle the line spool (1) as described in section
8.4 Assembly. Press the spool together and remove
one half of the housing. Fig. 35
2. Take the spool plate out of the line spool housing.
Fig. 36
3. Remove any remaining cutting line.
4. Place the new cutting line in the center and hang the
loop which has formed into the recess in the spool
splitter. Fig. 37
5. Wind the line onto the spool counter-clockwise and
under tension. The spool splitter will separate the two
halves of the line. Fig. 38
6. Hook the last 15cm of the two ends of the line onto
the opposite lying line holders of the spool plate. Fig.
39
7. Thread the two ends of the line through the metal
eyelets in the line spool housing .
8. Press the spool plate into the line spool housing.
Fig. 36
9. Pull the two line ends sharply to release them from
the line holders.
10. Join the housing parts together again. Fig. 35
11. Cut the excess line to a length of around 13cm. This
will reduce the load on the engine when starting and
warming up.
12. Remount the line spool (see section 8.4). If you are
replacing the complete line spool, skip points 3-6.
Grinding the safety hood blade
The safety hood blade can become blunt over time.
• When you notice this, undo the screw holding the
safety hood blade on the safety hood.
• Clamp the blade in a vise.
• Sharpen the blade with a fl at fi le and make sure
that the angle of the cutting edge is not altered in the
process. File in one direction only.
Replacing and resharpening the cutting blade at the
end of the mowing season always resharpen the cutting
blade or, if required, replace the cutting blade with a new
one.
Unbalanced blades will cause the brush cutter to vibrate
violently-risk of accident!
Change and clean the spark plug Fig. 32 - 33
1. Once the engine has cooled, remove the spark plug
using the socket spanner supplied.
2. Clean the plug with a wire brush.
3. Using a feeler gauge; set the gap to 0.5-0.7 mm.
4. Install the spark plug carefully by hand, to avoid cross-
threading.
5. After the spark plug is seated, tighten with spanner to
compress the washer.
Clean the air filter Fig. 28 - 31
Soiled air filters reduce the engine power by supplying
too little air to the carburetor. Regular checks are
therefore essential.
