If necessary:
Retighten accessible fastening screws and nuts.
You will avoid excessive wear and tear and dam-
ages of the tool, when you follow the instructions
in this manual.
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! Install the cutting knife again
Replacing and resharpening the cutting blade at the
end of the mowing season
Grinding the cutting blade (17)
If the blades become slightly dull, you can sharpen
them yourself.
•
Fasten the blade in a vice.
•
Grind all 3 cutting unit blades using a flat file and
make sure to maintain the angle of the cutting
edge. (~25°) Only file in one direction.
•
Replace the blades after sharpening them five
times at the latest.
Replacing and resharpening the cutting blade at the
end of the mowing season always resharpen the cut
-
ting blade or, if required, replace the cutting blade
with a new one.
Unbalanced blades will cause the brush cutter to vi-
brate violently-risk of accident!
Always start with running at full speed chain to cut.
Recoil
The recoil occurs when the chain on top of rail sud-
denly stuck because it is jammed or encounters a
foreign object in the wood. The chain can jerkily hold
the saw against the operator. Rebounds happen of-
ten if the top rail is used for cutting.
Avoid recoil
Be aware of the forces and situations that can lead to
jamming of the chain on top of rail.
Do not cut more than one branch at a time.
Do not tilt the rail to the side when you pull them out
of a cutting gap, since the chain could get caught
otherwise.
10. Maintenance
WARNING:
Always wear protective gloves when
working on or around cutting tools.
For non-use, transport or storage always attach the
transport guard to all cutting tools. Fig. 1 (14a, 15a,
17c)
Before performing any maintenance or cleaning
work, always turn off the engine and pull out the
spark boot plug.
1.
Do not spray the unit with water. It damages the
engine.
2. Clean the unit with a cloth, hand brush, etc.
3. Use a moist piece of cloth to clean the plastic
parts. Do not use any cleaning agents, solvents,
or sharp objects.
4. During the course of work, wet grass and weed
wraps around the drive shaft below the cutting
guard for technical reasons. Remove this, oth-
erwise the engine will overheat because of too
much friction. Fig. 45
Regular checks
Keep in mind that following specifications relate to
normal usage. Owing to circumstances (longer pe-
riods of daily work, severe dust exposure, etc.), the
specified intervals will become correspondingly
shorter.
•
Before starting work, after tank filling, after impact
or dropping:
Check the cutting tools for secure seating, general
visual check for cracks and damage.
•
Immediately replace damaged or blunt cutting
tools, even in the event of minor hairline cracks.
•
Sharpen cutting tools (also when required).
•
Weekly inspection:
Lubrication of gear (also, if necessary).
