Service
WINTER STORAGE
To prepare your Husqvarna mower for winter storage,
perform the routine maintenance and necessary
adjustments and record the part numbers of worn or
broken parts so they may be ordered and replaced
before the next mowing season. Use only authentic
Husqvarna replacement parts to insure proper fit and
the safety of your mower is maintained.
Treat the fuel in the tank with a fuel stabilizer (such as
STA-BIL). This will minimize the formation of fuel gum
deposits during storage. Read and follow the mix ratio
on the container. Run the engine for at least 10
minutes after adding the stabilizer to bring it into the
carburetor.
These few tips will help make your mower ready when
needed for the next mowing season and insure many
years of dependable service.
