Replacing the line spool/cutting line Fig. 31 - 36
1. Pull off the line guard cap from the line spool (5) by
forcefully pressing between the retaining plates.
2. Remove the spool with line remaining and the
compression spring.
3. Remove the used up spool.
4. Take the new line spool and pull out 10 cm at both
lines each.
5. Now, place the line spool (5) on the tapered spring,
and guide both lines each through the round metal
lugs at the line spool housing.
6. Then place the spool cover on the new line spool (5).
Turn it so that the plates of the spool cover are pushed
with the springs in the line spool housing.
7. Now, press the spool cover together with the line
spool, until it engages in the line spool housing.
8. The knife (A) in the protective hood (18) shortens the
trimming line to the correct length, when the engine
starts again.
Grinding the safety hood blade Fig.25 (A)
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 flat file and make sure that
the angle of the cutting edge is not altered in the
process. File in one direction only.
• Important! Reassemble the cutting knife.
Replacing and resharpening the cutting blade at the
end of the mowing season always resharpen the cutting
blade or, if required, replace the cutting blade with a new
one.
Grinding cutter blade (17)
If the blade is only slightly dull, they can re-sharpen
themselves.
• 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. (~25°) File in one direction only.
Replace the blade at the latest after five times
scharpening.
Replace the blade with heavy wear or broken blade.
Unbalanced blades will cause the brush cutter to vibrate
violently-risk of accident!
Lubricate angle transmission
Lubricate with lithium-based grease. Remove the screw
Fig.8(O) and put in the grease, turning the shaft manually
until grease emerges, then replace the screw.
Attention! Fill only a small amount of grease. Do not
overfill.
Change and clean the spark plug Fig. 37 - 38
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.
• Wait until the engine has cooled down completely.
• Pull the spark plug cap off the spark plug, and use the
supplied spark plug wrench to remove the spark plug
by turning.
• 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.
Clean the air filter Fig. 39 - 42
Soiled air filters reduce the engine power by supplying
too little air to the carburetor. Dust and pollen plug up
the pores of the filter made of foamed plastic. Regular
checks are therefore essential.
• Unclip the air filter cover and remove the sponge filter
element.
• To avoid objects falling into the air tank, replace the air
filter cover.
• Wash the filter element in warm soap water, rinse and
allow drying naturally.
Important: Never clean the air filter with petrol or
inflammable solvents.
In order not to shorten the service life of the engine, a
damaged air filter must be replaced at once.
Care of the guide rail
Turn the rail around every time you have the chain
sharpened or replaced. This will avoid a one-sided wear
of the rail, especially at the top and bottom.
Regularly clean
1 = the opening for the oil supply
2 = the oil passage
3 = the raceway groove of the rai
Servicing and sharpening of saw chain
The correct sharpened chain
Working effectively with the chainsaw is only possible if
the chain is in good condition and
sharp. This also reduces the risk of kickback. The chain
can be re-sharpened by any dealer. Do not attempt
to sharpen the chain yourself unless you have the
necessary special tools and experience. A properly
sharpened chain goes way through the wood and it
requires very little pressure. Do not work with a dull or
damaged chain. It increases physical exertion, increase
the vibrations and leads to unsatisfactory results and
higher wear.
• Clean the chain.
• Check it.
