Turn on the water and start the engine so
that the blade moves horizontally around the
skirt. Allow the engine to run for 3-5 minutes.
Do not use this method unless the spring-
loaded � ap on the skirt is down!
Sharpening the blade
Remove the spark plug cap (13) from the
spark plug. Remove the bolt and washer
securing the blade to the crankshaft and
remove the blade and adapter.
Caution: The blade can be sharp!
Get the knife sharpened at a professional
workshop if you do not have the necessary
experience to do it yourself.
The blade must be completely in balance
after sharpening. You can also insert a
screwdriver into the hole in the middle of
the blade and see if the blade balances on
the screwdriver. If not, sharpen more of the
blade's heavy side.
Replace the blade with a new one if it is
damaged, bent or otherwise out of balance.
Lubricate the crankshaft and adapter using
lubricating spray or a light oil.
Replace the components in reverse order and
check that the blade is secure. The spare part
number on the blade must be facing away
from the adapter.
The bolt must be tightened with a torque of
40-50 Nm.
