Two-stroke oil
For the best results use
HUSQVARNA two-stroke
oil, which has been
specially produced for
power cutters. Mixing ratio
1:50 (2%).
If HUSQVARNA two-stroke
oil is not available you can
use a high quality two-
stroke oil intended for air
cooled engines. Contact
your dealer when selecting
an oil. Mixing ratio: 1:33
(3%) - 1:25 (4%).
Never use two-stroke oil intended for water cooled outboard
motors, so-called outboard motor oil.
Never use oil intended of four-stroke engines.
!
Fuel mixture
WARNING! the power cutter is fitted with a
two-stroke engine and must always be run on
a mixture of petrol and two-stroke oil. To
ensure the correct mixture proportions it is
important to measure the quantity of oil
accurately. When mixing small amounts of
fuel small discrepancies in the amount of oil
has a great bearing on the proportions of the
fuel mixture. Always provide good ventilation
when handling fuel.
Petrol
Use unleaded or quality
leaded petrol.
The lowest recommended
octane rating is 90. If you
run the engine on a petrol
with a lower octane rating
than 90 so-called “knocking“
can occur. This leads to an
increased engine
temperature, which can
result in a serious engine
breakdown.
FUEL HANDLING
Mixture
Always mix petrol and oil in
a clean container intended
for petrol.
Always start by filling half
the quantity of petrol
required. Then add the
entire oil quantity. Mix
(shake) the fuel mixture. Fill
the remaining quantity of
petrol.
Mix (shake) the fuel mixture
carefully before filling in the
machine‘s fuel tank.
Do not mix fuel for more
than approx. 2 months use.
If the clearing saw is not
used for a long period of
time, the fuel tank should be
emptied and cleaned.
!
Fuelling
WARNING!The following precautions reduce
the risk of fire:
Do not smoke or place any sources of heat in the
vicinity of the fuel.
Never refuel when the engine is running.
Open the fuel cap slowly when fuelling so that any over
pressure is released slowly.
Tighten the fuel cap carefully after refuelling.
Always move the machine from the fuelling place
before starting.
Keep the handle dry, clean
and free from oil and fuel.
Clean around the fuel cap.
Clean the fuel tank
regularly. The fuel filter
should be changed at least
once per year
Contamination in the tank
can disrupt operations.
Ensure that the fuel is well
mixed by shaking the
container before filling the
tank.
Always exercise care when
filling the fuel. Move the
power cutter at least three
metres from the filling area
before starting. Make sure
the fuel cap is tightened.
