Fuel Handling; Fuel - Jonsered GT 2125 Operator's Manual

Fuel

CAUTION! The machine is equipped with a two-stroke engine
and must always been run using a mixture of gasoline and
two-stroke engine oil. It is important to accurately 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 drastically affect the ratio of the
mixture.
WARNING! Always ensure there is adequate
!
ventilation when handling fuel.
Gasoline
CAUTION! Always use high grade unleaded oil mixed
gasoline (minimum 87 RON). If your machine is equipped with
a catalytic converter (see chapter on Technical data) always
use a good quality unleaded petrol/oil mixture. Leaded petrol
will destroy the catalytic converter and it will no longer serve
its purpose.
Use low-emission gasoline, also known as alkylate gasoline,
if it is available.
• This engine is certified to operate on unleaded
gasoline.
• The lowest recommended octane rating is 87. If you run
the engine on lower octane rating than 87 so-called
"knocking" can occur. This leads to an increased engine
temperature, which can result in a serious engine
breakdown.
• When working at continuous high revs a higher octane
rating is recommended.
