Air Intake Screen; Spark Plug; Air Filter - Husqvarna 560 BTS Operator's Manual

Air intake screen

Check that the air intake is not blocked on all sides
including the underside, for example, by leaves or
rubbish. A clogged air intake reduces the machine's
blowing capacity and increases the engine's working
temperature, which can result in engine failure. Stop the
engine and remove the object.
WARNING! Never use the blower if the
!
screen is not in place. Before use, check
that the screen is in place and
undamaged.

Spark plug

The spark plug condition is influenced by:
• Incorrect carburetor adjustment.
• An incorrect fuel mixture (too much or incorrect type
of oil).
• A dirty air filter.
These factors cause deposits on the spark plug
electrodes, which may result in operating problems and
starting difficulties.
Clean the outside of the spark plug. Remove it and check
the electrode gap. Adjust the gap to 0,6-0,7 mm, or
replace the spark plug. Check that the spark plug is fitted
with a suppressor.
