FUEL HANDLING

Fuel mixture

CAUTION! The machine is equipped with

atwo--stroke engine and must always be run using a mixture of gasoline and two-- stroke engine oil. It is important to accu- rately measure the amount of oil to be mixed to ensure that the correct mixture is obtained. When mixing small amounts of fuel, even small inaccuracies can drastical- ly affect the ratio of the mixture.

WARNING: Always ensure there is adequate ventilation when handling fuel.

Gasoline

CAUTION! Always use high quality unleaded gasoline.

SThis engine is certified to operate on

unleaded gasoline.

SThe lowest recommended octane rating is 87. If you run the engine on lower oc- tane rating than 87, “knocking” can oc- cur. This leads to an increased engine

temperature, which can result in a seri- ous engine breakdown.

SWhen working at continuous high revs a higher octane rating is recommended.

Two-stroke oil

SFor great results and performance use HUSQVARNA two--stroke oil, which is specially formulated for our two--stroke

engines. Mixture 1:50 (2%).

STo maximize the life of your trimmer, you may choose to use a high quality syn- thetic oil formulated for two--stroke engines. Mixture 1:50 (2%).

SNever use two--stroke oil intended for water--cooled outboard engines,

sometimes referred to as outboard oil.

SNever use oil intended for four--stroke engines.

	1	2 1/2
	2 1/2	6 1/2
	5	12 7/8

Mixing

SAlways mix the gasoline and oil in a clean container intended for fuel.

SAlways start by flling half the amount of the gasoline to be used. Then add the entire amount of oil. Mix (shake) the fuel mixture.

Add the remaining amount of gasoline.

SMix (shake) the fuel mixture thoroughly before filling the machine’s fuel tank.

SDo not mix more than one month’s sup- ply of fuel at a time.

SIf the machine is not used for some time, the fuel tank should be emptied and cleaned.

WARNING: The catalytic con- verter muffler gets very hot during and after use. This also applies during idling. Be aware of the fire hazard, especially when working near flammable substances and/or vapors.

Fueling

WARNING: Taking the following precautions, will lessen the risk of fire:

Do not smoke or place hot objects near fuel.

Always shut off the engine before refueling.

Always stop the engine and let it cool for a few minutes before refu- elling.

When refueling, open the fuel cap slowly so that any excess pressure is released gently.

Tighten the fuel cap carefully after refueling.

Always move the machine away from the refueling area before starting.

Min. 10 ft.

(3 m)

SClean the area around the fuel cap. Contamination in the tank can cause

operating problems.

SEnsure that the fuel is well mixed by shak- ing the container before filling the tank.
