Husqvarna 541EA Operator's Manual page 11

Maintenance
Clean the external surface of the carburetor and
the area around it.
Clean the cooling system of the product.
Check the clutch, clutch springs and the clutch
drum for wear. Replace if it is necessary.
Clean the muffler.
Replace the spark plug. Make sure that the
spark plug is assembled with a suppressor.
To adjust the carburetor
The basic carburetor settings are adjusted during
testing at the factory. Adjustment must be carried
out by a trained technician.
To check the muffler
WARNING: Do not use a product that has
a defective muffler. Always replace a
defective muffler.
WARNING: Risk of burn or fire. Mufflers
with catalytic converters get very hot
during operation.
WARNING: Risk of fire. The muffler
decreases the noise level and identifies
the exhaust gases from the operator. The
exhaust gases are hot and can contain
sparks.
CAUTION: The spark arrester screen must
be replaced if it is damaged. Do not use a
product if the spark arrester screen on the
muffler is missing or defective.
CAUTION: If the spark arrester screen is
blocked, the product will be too hot. This
will cause damage to the cylinder and
piston.
1. Make sure that the muffler is not damaged.
2. Make sure that the muffler is correctly attached to
the product.

To check the air cleaner
• After every 25 hours of operation, please remove
the air cleaner cover and inspect the air cleaner. If
it is too dirty, wash it carefully in warm water
containing a neutral detergent, and put it back to
its original position after drying it thoroughly.
• If the air cleaner is distorted or damaged, please
replace it with a new one.
• If the air cleaner is blocked, the efficiency of the
engine will be reduced. In addition, the engine
interior will suffer abnormal wear if it is operated
without filter or if continually operated with a
distorted or damaged filter.
To check the fuel filter
• After every 25 hours of operation, empty the fuel
tank, detach the fuel filter from the tank, and
remove all dirt. If the filter is too clogged, please
replace it with a new one.
• If the fuel filter is clogged, the engine speed may
be limited or speed fluctuations may occur.
• If the engine is operated without a fuel filter, dirt
will accumulate in the carburetor and cause it to
malfunction
