Cleaning The Air Filter; Gear; Fuel FIlter; Spark Plug - Husqvarna 143AE15 Manual De Instrucciones

• Excessive fuel consumption.
Clean the filter every 25 hours, or more regularly if
conditions are exceptionally dusty.
Cleaning the air filter
Remove the air filter cover and take out the filter. Wash it
clean in warm, soapy water. Ensure that the filter is dry
before refitting it.
An air filter that has been in use for a long time cannot be
cleaned completely. The filter must therefore be replaced
with a new one at regular intervals. A damaged air filter
must always be replaced.

Gear

Check the oil level of the gear box every 50 hours of use
and change with new oil as necessary (SAE 80-90).

before taking any further action. If the spark plug is dirty,
clean it and check that the electrode gap is 0,6-0,7 mm.
