directive 2006/42/EC is enforced, this cleaning
should be done by your servicing dealer).

Allow it to cool down before carrying out this operation.
In some regions, it is prohibited to operate an engine without a
spark arrester.

bolts [1] from the muffler
protector [2] and remove the
muffler protector.

screws [3] from the spark
arrester [4] and remove the

around the exhaust port and
spark arrester. Clean if
necessary.

there are any breaks or
tears.
5. Install the spark arrester [4]
and muffler protector [2] in
the reverse order of removal.

BLADE CLUTCH LEVER FREE PLAY
Measure the clearance [11] at the top of the lever [3]
by holding the yellow button [12] pressed in.
It must be between 5 and 10 mm.
If necessary:
1. Undo the lock nuts [14] with a
10 mm spanner.
2. Move the nuts [14] up or
down as necessary.
3. Retighten the lock nuts [14]
and recheck the clearance.
4. Start the engine outdoors and engage the blade clutch lever.
Check that the blade starts to rotate when you pull the lever to
