Checking the blade

Loading nylon line

Every unit is test run at the factory and the carburettor is fine
tuned for maximum performance.
Before adjusting carburettor, clean or replace air filter, start en-
gine and run several minutes to bring it to operating temperature.
To adjust the carburettor proceed as follow:
Start engine and turn "idle" speed adjustment screw clockwise
until the cutting attachment begins to turn, then turn the screw
anticlockwise until the cutting attachment stops turning. Fur-
thermore, give the screw an additional 2 turn. Repeat the pro-
cess of accelerating to full throttle and return to idle a few
times. Check that the cutting attachment stops moving at idle.
If a tachometer is available, the engine idle speed should be
final adjusted to 3000 r/min.
NOTE
When the carburettor cannot be adjusted properly with the idle
speed adjustment screw (T), you must contact an authorized
service dealer.
Use only blade designated for this model by the manufacturer.
When a crack is noticed on the blade, do not use it but replace
with a new one.
Ensure that the blade is correctly fitted in accordance with the
instructions.
When the cutting blade becomes dull due to wear reverse it for
further use.

Replace with new one.
