Replacing the line spool/cutting line Fig. 41 - 46
1. Dismantle the line spool (1) as described in section
8.3 Assembly. Press the spool together and remove
one half of the housing. Fig. 42
2. Take the spool plate out of the line spool housing.
Fig. 43
3. Remove any remaining cutting line.
4. Place the new cutting line in the center and hang the
loop which has formed into the recess in the spool
splitter. Fig. 44
5. Wind the line onto the spool counter-clockwise and
under tension. The spool splitter will separate the two
halves of the line. Fig. 45
6. Hook the last 15cm of the two ends of the line onto
the opposite lying line holders of the spool plate. Fig.
46
7. Thread the two ends of the line through the metal
eyelets in the line spool housing .
8. Press the spool plate into the line spool housing.
Fig. 43
9. Pull the two line ends sharply to release them from
the line holders.
10. Join the housing parts together again. Fig. 42
11. Cut the excess line to a length of around 13cm. This
will reduce the load on the engine when starting and
warming up.
12. Remount the line spool (see section 8.3). If you are
replacing the complete line spool, skip points 3-6.
Grinding the safety hood blade Fig.24 (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 (4)
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!
Change and clean the spark plug Fig. 35 - 36
1. Once the engine has cooled, remove the spark plug
using the socket spanner supplied.
2. Clean the plug with a wire brush.
3. Using a feeler gauge; set the gap to 0.5-0.7 mm.
4. Install the spark plug carefully by hand, to avoid cross-
threading.
5. After the spark plug is seated, tighten with spanner to
compress the washer.
Clean the air filter Fig. 37 - 40
Soiled air filters reduce the engine power by supplying
too little air to the carburetor. 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.
m
Warning!
Never run the engine without the air filter element
installed.
Lubricate angle transmission
Lubricate with lithium-based grease. Remove the screw
and put in the grease, turning the shaft manually until
grease emerges, then replace the screw.
Adjusting the idle speed Fig. 52
If the cutting device runs idle, correct the idle speed.
1. Allow the engine to warm for 3-5 minutes
(No high speeds!).
2. Turn the adjusting screw (S): clockwise
- idle speed increases (+)
counterclockwise
- Idling speed decreases (-)
The idle speed is 3000 min-1
Contact the manufacturer if the cutter continues to run at
idle.
Do not continue to operate the unit!
