The knife in the protective hood shortens the
trimming line to the correct length, when the
engine starts again.
Maintenance and Care
Gear Lubrication
Check the filling of lubrication grease every 25
hours of operation.
- Use an Allen key to remove the plug screw by
turning (B32).
- When you cannot see any grease on the screw,
fill approx. 5 g lubrication grease (DIY store) into
the gearbox case, and close the ller opening
again.
Keep in mind that the gearbox case should never
be completely filled with lubrication grease.
Air filter
After working for longer time, you should clean
the air filter. Dust and pollen plug up the pores of
the filter made of foamed plastic.
- Remove the cover (B33), and wash the filter (B34)
in mild soap water. Caution: Do not use any
gasoline or solvent.
- Dry the filter before you insert it again.
In order not to shorten the service life of the
engine, a damaged air filter must be replaced at
once.
Adjustment of Spark Plug
Check the spark plug air gap at least once a year
or when the engine starts poorly. The correct gap
between ignition flag and ignition contact
is 0.25"/0.63 mm (B35).
- Wait until the engine has cooled down
completely.
- Pull the spark plug cap (B36) off the spark plug,
and use the supplied spark plug wrench to
remove the spark plug by turning (B37).
- When the electrode is severely worn out or
reveals a strong incrustation, the spark plug must
be replaced with an equivalent plug.
A strong incrustation of the spark plug can be
caused by: Amount of oil is too high in the
gasoline mix, poor oil quality, old gasoline mix, or
plugged up air filter.
- Screw the spark plug by hand completely into
the thread. (Avoid jamming it)
- Use the supplied spark plug wrench to tighten
the spark plug.
- When using a torque wrench, the tightening
torque is 12-15 Nm.
- Plug the spark plug socket correctly on the plug.
Adjustment of Carburetor
The carburetor was adjusted to optimum
performance in the factory. Should readjustment
be necessary, please contact a service center.
Idle-Running Speed
Make sure before each use that the cutting tool
does not rotate when the engine is running idly.
Should the cutting tool rotate when the engine is
running idly, you can adjust it at the carburetor.
- Use a screwdriver to turn the idle adjusting
screw just so far that the cutting tool will not
rotate any longer.
Trimming the Line Knife
- When the trimming line is no longer cut clean
during feeding, use a file to re-sharpen the
cutting edge (B38). File in one direction and in the
specified angle.
