will reduce the load on the engine when starting up
and warming up.
▶ 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 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.
9.3 Maintenance of the air fi lter
Soiled air fi lters reduce the engine output by supply too
little air to the carburetor. Regular checks are there
-
fore essential. The air fi lter 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.
▶ Remove the air fi lter cover (Fig. 10a).
▶ Remove the fi lter element (Fig. 10b/10c).
▶ Clean the fi lter element by tapping it or blowing it.
▶ 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 neces
-
sary clean it with a copper wire brush. Thereafter service
the spark plug after every 50 hours of operation.
▶ Pull out the spark plug connector (20) (Fig. 11a).
▶ Remove the spark plug (Abb. 11b) with the supplied
spark plug wrench (27).
▶ Assemble in reverse order.
9.5 Carburetor settings
Important. Settings on the carburetor may only be made by
authorized customer service personnel.
The air fi lter cover must be removed before any work on
the carburetor, as shown in Figures 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 „Troubleshooting“, 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 completely 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.
▶ Undo the adjusting screw (Fig. 13b/Item D) until the
carburetor slide is completely open when the throttle
is fully activated, as shown in Figure 13a.
▶ Retighten the lock nut.
9.6 Setting the idling speed
Note! Set the idling speed when the equipment is
warm.
The idling speed may only be adjusted by an authorized
service center. The starting speed of the cutting tool
must be at least 1.25 times the idling speed.
9.7 Applying grease to the gear unit
After every 20 hours of use add a little gear grease (ap -
prox. 10 g.) at the lubrication nipple (C) (Fig. 7c).
10. CLEANING, STORAGE AND
TRANSPORT
10.1 Cleaning
▶ Keep the handles free of oil so that you can maintain
a firm grip.
▶ Clean the equipment as required with a damp cloth and,
if necessary, mild washing up liquid.
Important!
Always pull out the spark boot plug each time before
carrying out any cleaning. Never immerse the equipment in
water or other liquids in order to clean it.
Store the equipment in a safe and dry place out of the
reach of children.
10.2 Storage
Important: Never put the equipment into storage
for longer than 30 days without carrying out the
following steps.
Important information about storage!
Store the petrol device as shown in Fig. 15a. If it is stored
suspended or upright (Fig. 15b) or sideways, this will cause
engine oil to fl ow into the combustion chamber, which
will prevent the device from starting.
