To start the engine on
WARNING: If the cutting unit does not
stop when you adjust the idle speed,
speak to your nearest servicing dealer.
Do not use the product until it is correctly
adjusted or repaired
Note: The idle speed is correct when the engine
operates smoothly in all positions. Refer to
data on page 16 for the recommended idle speed.
To do maintenance on the muffler
The muffler decreases the noise level and directs the
exhaust gases away from the operator.
WARNING: Mufflers that have catalytic
converters get very hot during operation and
will stay hot for some time after you stop the
product. This also applies at idle speed. If
you touch the product it can result in burns
to the skin. Think about of the risk of fire.
