Fuel
!
WARNING! The pruning saw is equipped with a
two-stroke engine and should always be run on a
mixture of petrol and two-stroke oil. To ensure the
correct mixture always measure out the amount of
oil that is needed accurately. If you mix small
amounts of fuel small errors in the amount of oil
will have a large effect on the mixture ratio. Always
ensure good ventilation when mixing fuel.
Petrol
Use good quality unleaded or leaded fuel.
The minimum recommended octane is 90. If the fuel is
less than 90 octane it may cause knocking. This will lead
to a higher engine temperature and may result in severe
engine damage.
Two-stroke oil
For best results use Husqvarna two-stroke oil, which is
specially developed for pruning saws.
Mixture ratio: 1:50 (2%).
If Husqvarna two-stroke oil is not available you may use
another high quality two-stroke oil made for air-cooled
engines.
Mixture ratio: 1:33 (3%) - 1:25 (4%).
Never use outboard oil, i.e. oil intended for water cooled
outboard engines.
Never use oil designed for four-stroke engines.
Mixing
Always mix petrol and oil in a clean container designed
for petrol.
Start by pouring half the petrol into the container. Then
add all the oil. Shake the fuel mixture well. Now add the
remaining petrol. Shake the fuel mixture thoroughly.
Then pour the fuel into the fuel tank of the pruning saw.
Never mix more fuel than you need for around 2 months
work. If you do not intend to use the pruning saw for a
long period the fuel tank should be drained and cleaned.
The table on the left shows the various mixture ratios.
