Fuel system
W ARNING!
Gasoline and gasoline fumes are poisonous and extremely flammable. Be especially careful when handling gasoline, as carelessness can result in personal injury or fire.
Only store fuel in containers approved for that purpose.
Never remove the fuel cap and fill the fuel tank when the engine is running.
Always stop the engine when refueling.
Do not smoke when filling the gasoline tank and do not pour gasoline in the vicinity of sparks or open flame.
Never fill the fuel tank indoors.
Before starting the machine after refueling, it should be moved at least 10 feet (3 M) from the location where it was filled.
Turn off the fuel supply for storage or transport.
If leaks arise in the fuel system, the engine must not be started until the problem has been resolved.
8011-205chg
Never fill the fuel tank indoors.
FUEL VALVE
8011-186
Close the fuel valve.
Check the fuel level before each use and leave space for the fuel to expand, because the heat from the engine and the sun can otherwise cause the fuel to expand and overflow .
Avoid overfilling. If you spill gasoline on the machine, wipe up the spill and wait until it has evaporated before starting the engine. If you spill gasoline on your clothing, change your clothing.

8011-222chg
Fueling always poses an element of risk.
SAFETY INSTRUCTIONS
Maintenance
Never make adjustments with the engine running.
Disengage the drive units, shut off the engine and wait until all moving parts come to a complete stop before making adjustments, performing maintenance or cleaning the machine.
Disconnect the spark plug cable before beginning repair work.
Keep all components in serviceable condition and make sure all nuts, bolts, etc. are tight. Replace worn or damaged decals.
Be careful when checking work tools. Use gloves when performing maintenance work.
Never allow persons not trained in the use of the machine to perform service on it.
Always park the machine on even ground before performing maintenance or making adjustments.
8011-027

W ARNING!
Wait until all moving part s are completely still before performing maintenance on the machine.
Do not disassemble the engine. This can invalidate your engine warranty. Contact your dealer if you have any questions regarding service or guarantee matters. Follow all maintenance instructions.
Do not change the setting of governors and avoid running the engine with overly high RPM. If you run the engine too fast, you risk damaging the machine components.

PROTECTIVE EQUIPMENT

Personal equipment
Consult your Husqvarna dealer when selecting protective equipment. Our dealers have a broad assortment of equipment for professionals such as forestry workers and knowledge about occupational environment requirements and protective levels.
Before using the stump grinder, you may in many cases need to cut back the object with a power saw. Hence, it is appropriate to use personal protective equipment that fulfils requirements for working with both stump grinders and power saws.
The main difference is that you should wear protective glasses when operating the stump grinder while the wire mesh visor gives sufficient protection when using a power saw. Thus when using the stump grinder, we recommend using both a wire mesh visor to protect your face and protective glasses. Alternatively, you can use a Plexiglas face guard, but it scratches more easily and is more susceptible to soiling and fogging.
You require the following personal protective equipment:
1. Protective helmet (hard hat)
2. Ear protection
3. Face guard
4. Protective trousers
5. Protective glasses
6. Breathing protection (risk of dusty work environment)
7. Protective gloves
8. First aid kit
9. Protective boots or steel-toed shoes
