stones or foundations. For cutting dense stalks, 

position the blade as shown in Fig. 9f to prevent 

recoil.

9. Maintenance

Always switch o

ff

  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 (13) as described in 

section 5.1.6. Press the spool together (Fig. 

12a) and remove one half of the housing (Fig. 

12b). 

2.   Take the line spool out of the line spool 

housing (Fig. 12c).

3.  Remove any remaining cutting line.

4.  Place the new cutting line in the center and 

attach the resulting loop to the recess in the 

spool splitter (Fig. 12d).

5.  Wind the line on to the spool counter-clockwi-

se with tension. The spool splitter will separa-

te the two halves of the nylon line (Fig. 12e).

6.  Hook the last 15 cm of the two ends of the 

line to the line holders opposite the line spool 

(Fig. 12f).

7.  Thread the two ends of the line through the 

metal eyelets in the line spool housing (Fig. 

12c).

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 up and warming up.

11.  Fit the line spool again. See section 5.1.6. If 

you are replacing the complete line spool, 

ignore 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. 10a-10c)

 Soiled  air 

fi

 lters reduce the engine output by sup-

ply too little air to the carburetor. Regular checks 

are therefore essential. The air 

fi

 lter (10) should 

be checked after every 25 hours of use and clea-

ned 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. 10a).

2. Remove 

the 

fi

 lter element (Fig. 10b/10c).

3. Clean 

the 

fi

 lter element by tapping it or 

blowing it.

4.  Assemble in reverse order.

Important: Never clean the air 

fi

 lter with petrol or 

in

fl

 ammable solvents.

9.4 Maintenance of the spark plug 

(Fig. 11a-11c)

 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.   Remove the spark plug connector cover (20) 

as shown in Fig. 11a.

2.   Pull out the spark plug connector (16). (Fig. 

11b)

3.  Remove the spark plug (Abb. 11c) with the 

supplied spark plug wrench (27).

4.  Assemble in reverse order.

9.5 Carburetor settings

 Important. Settings on the carburetor may only be 

made by authorized customer service personnel.

To carry out any work on the carburetor you must 

fi

 rst remove the air 

fi

 lter cover as shown in Figu-

res 10a-10c.

Setting the throttle cable:

If the maximum speed of the equipment drops 

over time and you have ruled out all the other 

possible causes listed in section 12 „Troubleshoo-

ting“, it may be necessary to adjust the throttle 

cable. First of all check whether the carburetor 

opens fully when the throttle handle is pressed 

right through. This is the case if the carburetor 

slide (Fig. 13a) is completely opened when the 

throttle is fully activated. Figure 13a shows the 

correct setting. If the carburetor slide is not com-

pletely open, it must be adjusted.

The following steps are required to adjust the 

throttle cable:

• 

 Undo the lock nut (Fig. 13b/Item C) a few 

turns.
