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. 30 to prevent
recoil.
9. Maintenance
Always switch o
ff
the equipment and pull out
the spark boot plug (13) before carrying out any
maintenance work.
9.1 Replacing the line spool/cutting line
1. Dismantle the line spool (3) as described in
section 5.6. Press the spool together (Fig. 35)
and remove one half of the housing (Fig. 36).
2. Take the spool plate (K) out of the line spool
housing (Fig. 37).
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. 38)
5. Wind the line onto the spool counter-clockwi-
se and under tension. The spool splitter will
separate the two halves of the line. (Fig. 39)
6. Hook the last 15cm of the two ends of the
line onto the opposite lying line holders of the
spool plate. (Fig. 40)
7. Thread the two ends of the line through the
metal eyelets in the line spool housing (Fig.
37).
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.
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 5.6). 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 (Fig. 31-33)
Soiled air
fi
lters reduce the engine power by
supplying too little air to the carburetor. Regular
checks are therefore essential. The air
fi
lter (T)
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 should be checked more
frequently.
1. Remove the air
fi
lter cover (Fig. 31-32).
2. Remove the air
fi
lter (Fig. 33).
3. Clean the air
fi
lter by tapping it or blowing it
out.
4. Assemble in reverse order.
Warning!
Never clean the air
fi
lter with petrol or
in
fl
ammable solvents.
9.4 Maintenance of the spark plug (Fig. 34)
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 boot plug (Fig. 13).
2. Remove the spark plug (Fig. 34) with the sup-
plied multifunction tool (27).
3. Assemble in reverse order.
9.5 Carburetor settings
Important!
Settings on the carburetor may only
be made by authorized customer service person-
nel.
The air
fi
lter cover must be removed before car-
rying out any work on the carburetor, as shown in
Fig. 31 and 32.
