MIXING THE FUEL

This product is powered by a 2-stroke engine and
requires pre-mixing petrol and 2-stroke lubricant. Pre-
mix unleaded petrol and 2-stroke engine lubricant in a
clean container approved for petrol.
This engine is certified to operate on unleaded petrol
intended for automotive use with an octane rating of
91 or higher.
Do not use any type of pre-mixed petrol/lubricant
from fuel service stations; this includes the pre-
mixed petrol/lubricant intended for use in mopeds,
motorcycles, etc.
Use a high quality 2-stroke self-mixing lubricant for
air-cooled engines. Do not use automotive lubricant
or 2-stroke outboard lubricant.
Mix 2% synthetic 2-stroke oil into the petrol. This is a
50:1 ratio.
Mix the fuel thoroughly and each time before fueling.
Mix in small quantities. Do not mix quantities larger
than usable in a 30-day period. A 2-stroke lubricant
containing a fuel stabilizer is recommended.
