Introduction
WARNING: Read and understand the safety
chapter before you use the product.
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.
Premixed fuel
• Use Zenoah premixed alkylate fuel of a good quality,
for best performance and extension of the engine
life. This fuel contains less harmful chemicals
compared to regular fuel, which decreases harmful
exhaust fumes. The quantity of remains after
combustion is lower with this fuel, which keeps the
components of the engine more clean.
To mix fuel
Gasoline
• Use good quality unleaded gasoline with a maximum
of 10% ethanol contents.
CAUTION: Do not use gasoline with an
octane grade less than 90 RON/87 AKI.
Use of a lower octane grade can cause
engine knocking, which causes engine
damages.
• We recommend that you use gasoline of a higher
octane grade for work with continuously high rpm.
Two-stroke oil
• For best results and performance use Zenoah two-
stroke oil.
• If Zenoah two-stroke oil is not available, use a two-
stroke oil of good quality for air-cooled engines.
Speak to your servicing dealer to select the correct
oil.
CAUTION: Do not use two-stroke oil for
water-cooled outboard engines, also
referred to as outboard oil. Do not use oil
for four-stroke engines.
