Operation Fuel This product has a two-stroke engine. CAUTION: Incorrect type of fuel can result in engine damage. Use a mixture of gasoline and two-stroke oil. product and decrease the life time of catalytic converters. CAUTION: Do not use two-stroke oil for water-cooled outboard engines, also referred to as outboard oil. Gasoline CAUTION: Always use a quality gasoline/oil mixture of at least 90 octane (RON). There is a risk that use of lower octane grade causes knocking. This gives rise to high engine temperature, which can result in serious engine damage. CAUTION: If your product is equipped with a catalytic converter use a good quality unleaded gasoline/oil mixture. Leaded gasoline will destroy the catalytic converter. • Use low-emission gasoline, also know as alkylate gasoline, if it is available. CAUTION: Do not use oil for four-stroke engines. • For best results and performance use Husqvarna two-stroke oil. • If Husqvarna two-stroke oil is not available, use a different two-stroke oil of good quality for air-cooled engines. Speak to your servicing dealer to select the correct oil. Gasoline, l 5 10 15 20 Two-stroke oil, l 2% (50:1) 0.10 0.20 0.30 0.40 • Ethanol blended fuel, E10 may be used (max 10% ethanol blend). Using ethanol blends higher than E10 will cause lean running condition which can damage the engine. • We recommend a higher octane rating when you do work at continuous high speed. Husqvarna alkylate fuel We recommend you to use Husqvarna alkylate fuel for best performance. The fuel contains less dangerous material compared to regular fuel, which decreases dangerous exhaust fumes. The fuel gives a low quantity of dangerous remainings when it is combusted, which keeps the components of the engine more clean. This extends the life of the engine.

Carefully measure the quantity of oil to be mixed to make sure that you get the correct mixture. 1. Fill half the quantity of the gasoline to be used. 2. Add the full quantity of oil and mix (shake) the fuel mixture. 3. Add the remaining quantity of gasoline. 1011 - 005 - 11

Operation
Fuel
This product has a two-stroke engine.
CAUTION:
Incorrect type of fuel can result in
engine damage. Use a mixture of gasoline
and two-stroke oil.
Gasoline
CAUTION:
Always use a quality gasoline/oil
mixture of at least 90 octane (RON). There
is a risk that use of lower octane grade
causes knocking. This gives rise to high
engine temperature, which can result in
serious engine damage.
CAUTION:
If your product is equipped with a
catalytic converter use a good quality
unleaded gasoline/oil mixture. Leaded
gasoline will destroy the catalytic converter.
•
Use low-emission gasoline, also know as alkylate
gasoline, if it is available.
•
Ethanol blended fuel, E10 may be used (max 10%
ethanol blend). Using ethanol blends higher than
E10 will cause lean running condition which can
damage the engine.
•
We recommend a higher octane rating when you do
work at continuous high speed.
Husqvarna alkylate fuel
We recommend you to use Husqvarna alkylate fuel for
best performance. The fuel contains less dangerous
material compared to regular fuel, which decreases
dangerous exhaust fumes. The fuel gives a low quantity
of dangerous remainings when it is combusted, which
keeps the components of the engine more clean. This
extends the life of the engine. Husqvarna alkylate fuel is
not available in all markets.
Two-stroke oil
CAUTION:
Unsatisfactory oil quality and/or
incorrect oil/fuel ratio can damage the
product and decrease the life time of
catalytic converters.
CAUTION:
Do not use two-stroke oil for
water-cooled outboard engines, also
referred to as outboard oil.
CAUTION:
Do not use oil for four-stroke
engines.
