housing (Fig. N3). Make sure that you do not
lose the spring or the washers.
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. N4)
5. Wind the line on to the spool counter-
clockwise with tension. The spool splitter will
separate the two halves of the nylon line
(Fig. N5)
6. Hook the last 15 cm of the two ends of the
line to the line holders opposite the line
spool (Fig. N6)
7. Thread the two ends of the line through the
metal eyelets in the line spool housing (Fig. N3).
8. Press the line spool into the line spool
housing. Ensure that the spring and
washers are in the correct position (Fig. N3).
9. Press the line spool cover on to the line
spool housing. Ensure that the two lugs (Fig.
N2/Item 1) in the line spool housing lock
into the appropriate recesses (Fig. N2/Item
2) in the line spool cover.
10. Pull the two line ends briefly and
powerfully to release them from the line
holders in the line spool.
11. 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.
12. Fit the line spool again. See point 5.1.5.
If you are replacing the complete line spool,
ignore points 3-6.
7.2.2 Maintenance of the air filter (Fig. J1-J2)
Soiled air filters reduce the engine output by
preventing the air reaching the carburettor.
Regular checks are therefore essential. The air
filter should be checked after every 25 hours
of use and cleaned if necessary. If the air
contains a lot of dust, the air filter should be
checked more frequently.
1. Remove the air filter cover (Fig.J1-J2)
2. Remove the filter element.
3. Clean the filter element by tapping it or
blowing it.
4. Assemble in reverse order.
Please note: Never clean the air filter with
petrol or inflammable solvents. Clean the air
filter with compressed air or by tapping it.
7.2.3 Maintenance of the spark plug
(Fig. K1-K2)
Spark plug gap = 0,6 mm. Tighten the spark
plug with a torque of 12-15 Nm.
Check the spark plug for dirt and grime
after 50 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 off the spark plug boot (Fig. K1)
by twisting.
2. Remove the spark plug (Fig. K2) with
the supplied spark plug wrench.
3. Assemble in reverse order.
7.2.4 Grinding the safety guard blade
The safety guard blade (Fig. L/Item F) can
become blunt over time. Clamp the blade
in a vise. Sharpen the blade with a flat file
and make sure that the angle of the cutting
edge is not altered in the process. File in one
direction only.
7.2.5 Carburettor settings
Important.
Settings on the carburettor may
only be made by an authorised petrol
repair agent.
