Winter storage

At the end of the season, the machine should
be readied for storage (or if it will not be in use
for longer than 30 days). Fuel allowed to stand
for long periods of time (30 days or more) can
leave sticky residues that can plug the
carburetor and disrupt engine function.
Fuel stabilizers are an acceptable option to
reducing sticky residues during storage. If
alkylate gasoline (Aspen) is used, stabilizers
are unnecessary because this fuel is stable.
However, you should avoid switching between
regular and alkylate gasoline as sensitive
rubber components can harden. Add stabilizer
to the fuel in the tank or in the storage
container. Always use the mixing ratios
specified by the manufacturer of the stabilizer.
Run the engine for at least 10 minutes after
adding the stabilizer so that it reaches the
carburetor. Do not empty the fuel tank and the
carburetor if you have added stabilizer.
Never store an engine with fuel in the
tank indoors or in poorly ventilated
spaces where fuel vapor can come in
contact with open flame, sparks or a
pilot light such as in a boiler, hot water
tank, clothing drier, etc.
Handle the fuel with caution. It is very
flammable and careless use can cause
serious damage to person and
property. Drain the fuel into an
approved container outdoors and far
away from open flame. Never use
gasoline for cleaning. Use a degreaser
and warm water instead.

Service

When ordering spare parts, please specify the
purchase year, model, type, and serial number.
Always use genuine Husqvarna spare parts.
An annual check-up at an authorized service
workshop is a good way to ensure that your
machine performs its best the following season.

WARNING!

STORAGE

To ready the machine for storage, follow these
steps:
1. Clean the machine carefully, particularly the
chassis and working equipment. Mend damage
to the paint to prevent rust.
2. Inspect the machine for worn or damaged parts
and tighten any nuts or bolts that may have
become loose.
3. Change the engine oil; dispose of properly.
4. Open the fuel valve. Empty the fuel tank (1) and
the carburetor (2).
5. Close the fuel valve.
6. Remove the spark plug and pour about a
tablespoon of engine oil in the cylinder. Turn
over the engine so that the oil is evenly
distributed and then refit the spark plug.
Put the engine in the compression phase where
the triangle mark on the sleeve of the starter is
aligned with the upper hole in the starter.
Note: Compression phase occurs every second
revolution.
7. Lubricate all grease nipples, joints and shafts
as described in the chapter "Lubrication/
Lubrication schedule".
8. Store the machine in a clean, dry place and
cover it for extra protection.
