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 vice.
•
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
•
Replace and sharpen the cutting blade at the end of the mowing season.
Grinding the cutting blade
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.
•
Replace and sharpen the cutting blade at the end of the mowing season. Always sharpen the cutting blade
or, if required, replace the cutting blade with a new one.
•
Unbalanced blades will cause the brush cutter to vibrate violently-risk of accident!
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.
Attention! Fill only a small amount of grease. Do not overfill.
Change and clean the spark plug
•
Check the spark plug air gap at least once a year or when the engine starts poorly. The correct gap 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 re- placed
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
Soiled air filters reduce the engine power by supplying too little air to the carburettor. 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.
