jects (for example stones) being thrown up (Fig.
11e).
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.
Sawing
The equipment is not suitable for sawing.
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.
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. For cutting dense stalks,
position the blade as shown in Fig. 9f to prevent
recoil.
9. Maintenance
Always switch off the equipment and pull out the
spark boot plug before carrying out any mainte-
nance work.
9.1 Replacing the line spool/cutting line
1. Dismantle the line spool (16) as described in
section 5.1.8. Press in the side lugs slightly
while simultaneously pressing the spool down
and turning it clockwise (Fig. 15a). Remove
one half of the housing.
2. Take the line spool out of the line spool
housing (Fig. 15c).
3. Remove any remaining cutting line.
4. Place the new cutting line in the center and
hang the loop which has formed into the re-
cess in the spool splitter (Fig. 15d)
5. Wind up the line counter-clockwise and under
tension. The spool splitter will separate the
two halves of the line (Fig. 15e)
6. Hook the last 15cm of the two ends of the

line onto the opposite lying line holders of the
spool plate (Fig. 15f)
7. Thread the two ends of the line through the
metal eyelets in the line spool housing (Fig.
15c).
8. Press the line spool into the line spool
housing.
9. Pull the two line ends sharply to release them
from the line holders.
10. Cut the excess line to a length of around 13
cm. This will reduce the load on the engine
when starting and warming up.
11. Refi t the line spool (see section 5.1.8). If you
are replacing the complete line spool, skip
points 3-6.
9.2 Grinding the safety hood blade
The safety hood blade can become blunt over
time. When you notice this, undo the screw hol-
ding 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 cut-
ting edge is not altered in the process. File in one
direction only.
9.3 Maintenance of the air fi lter
Soiled air fi lters reduce the engine output by
supplying too little air to the carburetor. Regular
checks are therefore essential. The air fi lter (37)
should be checked after every 25 hours of use
and cleaned if necessary. If the air contains a lot
of dust, the air fi lter must be checked more fre-
quently.
1. Remove the air fi lter cover (Fig. 12a/Item 36)
2. Remove the air fi lter (Fig. 12b/Item 37)
3. Clean the air fi lter by tapping it or blowing it
out.
4. Assemble in reverse order.
Important: Never clean the air fi lter with petrol or
infl ammable solvents.
9.4 Maintenance of the spark plug
Spark plug sparking gap = 0.6mm. Tighten the
spark plug with a torque of 12 to 15 Nm. Check
the spark plug for dirt and grime after 10 hours of
operation and if necessary clean it with a copper
wire brush. Thereafter service the spark plug after
every 50 hours of operation.
1. Pull out the spark plug connector (38).
2. Remove the spark plug (Fig. 39) with the sup-
plied spark plug wrench (20).
3. Assemble in reverse order.
