Replacing The Air Filter - Husqvarna SG11 Operator's Manual

Replacing the air filter

If the engine seems weak, produces black smoke
or runs unevenly, the air filter may be clogged.
For this reason, it is important to clean and replace
the air filter regularly (see the maintenance
schedule for the proper service interval).
WARNING!
Allow the exhaust system to cool
before performing service. Risk for
burns.
Cleaning/replacement of the air filter is carried out
as follows:
1. Undo the wing nut (1) and lift off the cyclone
filter with the air filter cowling (2).
2. Remove the foam rubber pre-filter and clean
using a mild detergent.
Squeeze it dry with a clean cloth.
Soak it with new engine oil. Wind the filter in an
absorbent cloth and squeeze out excess oil.
3. Remove the wing nut in the air filter and
remove the paper filter. Tap the paper filter
against a fixed surface to remove dust. If the
paper filter is still dirty or damaged, it must be
replaced.
IMPORTANT INFORMATION
Do not use compressed air over 2 bar/30 PSI
to clean the paper filter.
Do not wash the paper filter.
Do not oil the paper filter.
4. Refit the air filter as follows:
Mount the paper filter in the air filter housing
and tighten the wing nut.
5. Refit the pre-filter on the paper filter.
6. Refit the cyclone filter with the air filter cowling.
