STORAGE
Storage
Winter Storage
At the end of the mowing 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 foul the 
carburetor and disrupt engine function.
Fuel stabilizers are an acceptable option as 
regards to the sticky residues that can occur 
during storage.
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.To ready the machine for storage, follow these 
steps:
1. Thoroughly clean the machine, especially 
under the mower deck. Touch up damage to 
the paint and spray a thin layer of oil on the 
underside of the mower deck to avoid 
corrosion.
2. Inspect the machine for worn or damaged 
parts and tighten any nuts or screws that may 
have become loose.
3. Change the engine oil; dispose of properly.
4. Empty the fuel tanks or add a fuel stabilizer. 
Start the engine and allow it to run until the 
carburetor is drained of fuel or the stabilizer 
has reached the carburetor.
5. Remove the spark plug and pour about a 
tablespoon of engine oil into the cylinder. 
Turn over the engine so that the oil is evenly 
distributed and then refit the spark plug.
6. Lubricate all grease zerks, joints, and axles.
7. Remove the battery. Clean, charge, and store 
the battery in a cool place, but protect it from 
direct cold.
8. Store the machine in a clean, dry place and 
cover it for extra protection.
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. WA R N I N G !
Never store an engine with fuel 
in the tank indoors or in poorly 
ventilated spaces where fuel 
vapor can come in contact with 
open flames, sparks, or a pilot 
light such as in a boiler, hot 
water tank, clothes drier, etc. 
Handle the fuel with care. It is 
very flammable and careless 
use can cause serious personal 
injury and property damage. 
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.
