HOW
Brush cutter
After each use
Remove earth and grass using a small wooden stick and a plastic brush.
Check that all components are firmly secured.
Check that there are no breaks, deformations, cracks, bending, crushing,
wear or rust.
Check the state of wear of the spool, line and guard. Replace if necessary.
Check the state of wear of the blade (if applicable) and its sharpness. Sharpen
or replace if necessary.
Hand grip and controls
After each use
Clean the dirt off, and thoroughly wipe traces of oil, petrol or humidity.
Engine
After each use
Using a brush, clean the cooling fins.
Keep all air vents in the engine clean and unobstructed.
Fuel lines and filter
After each use
Check that there are no cuts or cracks.
Check that there are no fuel leaks. If necessary, have the pipes replaced by an
authorised service centre.
The fuel filter, if any, is located along the fuel line or inside the tank. Check and
clean at least every three tank fills, or in case the engine malfunctions.
Air filter
Clean every 15 hours of
use. Replace every 50
hours of use. In case of
use in dusty areas, clean
and replace parts more
often.
1. Open the filter box cover following the picture of fig.G.
2. Remove the filter element.
3. Wash it with soap and water and rinse thoroughly.
4. Dry it thoroughly.
5. Soak it in clean engine oil.
6. Squeeze it to remove excess oil. Excess oil in the filter could cause an
engine malfunction.
7. Reinstall the filter and its cover.
Spark plug
Clean every 25 hours of
use. Replace every 100
hours of use. For the spark
plug type, check the tech-
nical specifications in the
manual.
1. Disconnect the spark plug cap and unscrew the spark plug with the correct
spanner.
2. Check the spark plug and in case of carbon residue, remove it with a metal
brush (not included). Replace the spark plug if the electrode is excessively worn
or the insulation is damaged.
3. Measure the distance between the electrodes using a thickness gauge (not
included) cross-checking with the value indicated in fig. G; adjust if necessary.
4. Screw the spark plug back in by hand.
5. Secure a used spark plug with around ¼ turn of the correct spanner, and a
new one with around ½ turn of the spanner.
Lubrication of the gears
of the cutting head
Every 10 hours of use
Through the grease fitting located on the cutting head (grease nipple or hole
with screw, fig.M pos.25), lubricate with gear grease, until the chamber is filled.
Lubrication of the rod
and of the flexible trans-
mission cable.
Every 20 hours of use
The extraction and lubrication of the transmission rod (18 Fig.A) and of the
flexible cable (21 Fig.A) must be performed by an authorized service center.
General check-up

80 hours of use.
Take the machine to an authorised service centre for a general check-up.
