BLADE SHARPENING (2-3-4 TOOTH)
1. Blades are reversible: when one side is no
longer sharp, the blade can be turned over
GB
and used on the other side (Fig. 17).
2. Blades are sharpened using a flat single-cut
file (Fig. 17).
3. To maintain the correct balance, file all cutting
edges uniformly.
4. If the blades are not sharpened correctly, this
can set up abnormal vibrations in the machine
and cause the blades themselves to break
ultimately.
BLADE SHARPENING (8 TOOTH)
Always check the general condition of the blade.
Correct sharpening permits the maximum
performance of the brush cutter. To sharpen the
teeth, use a file or grindstone and proceed with
light touches, respecting the corners and the
dimensions shown in Fig. 11.
SHARPENING THE SAW BLADE
• See the cutting attachment packaging for
correct sharpening instructions.
A correctly sharpened blade is essential for
working efficiently and to avoid unnecessary
wear to the blade and clearing saw.
• Make sure that the blade is well supported
when you file it. Use a 5.5 mm round file.
• The filing angle is 15°. File alternate teeth to
the right and those in between to the left. If
the blade has been heavily pitted by stones it
may be necessary to dress the top edges of
the teeth with a flat file, in exceptional cases. If
so, this should be done before filing with a
round file. The top edges must be filed down
by the same amount for all the teeth.
WARNING! – The wrong type of cutter or
an incorrectly sharpened blade will increase the
risk of kickback. Check mower blades for
deterioration or cracks, and replace if damaged.
WARNING: Never repair damaged

NYLON LINE HEAD
Only use line of the same diameter as the original
to avoid overloading the engine (Fig. 18).
In order to get more line out of the cutting head,
tap it lightly on the ground while working.
Note: Never hit the nylon head against hard spots
such as concrete or stones, it could be dangerous.
Replacing the nylon line on the LOAD&GO
trimmer head (Fig.19)
1. Cut 6.0 m of nylon line Ø 3.0 mm.
2. Align the arrows and insert the line into the

gloves during maintenance operations. Do not
carry out maintenance with the engine hot.
Never use fuel for cleaning operations.
AIR FILTER
Every 8-10 working hours, remove the cover (A,
Fig. 22), clean the filter (B).
Blow with compressed air, at a distance.
Replace if dirty or damaged. The engine runs
irregularly if the filter is clogged, with consequent
higher consumption and lower performance.
FUEL FILTER
Check fuel filter periodically. A dirty filter can cause
difficult starting and lower engine performance.
To clean filter proceed as follows: remove it from
fuel filling hole. Replace it (Fig. 21) if too dirty.
ENGINE
Clean cylinder fins with a brush or compressed
air periodically. Dangerous overheating of engine
may occur due to impurities on the cylinder.
SPARK PLUG
