WARNING
• Gasoline is very flammable. Avoid smoking or
bringing any flame or sparks near fuel. Make
sure to stop the engine and allow it cool before
refueling the unit. Select outdoor bare ground for
fueling and move at least 3m (10ft) away from the
fueling point before starting the engine.
• The RedMax/Komatsu Zenoah engines are
lubricated by oil specially formulated for air-cooled 2-
cycle gasoline engine use. If Komatsu Zenoah oil is
not available, use an anti-oxidant added quality oil
expressly labeled for air-cooled 2-cycle engine use.
(JASO FC GRADE OIL or ISO EGC GRADE)
• Do not use BIA or TCW (2-stroke water-cooling type)
mixed oil.

• Exhaust emission are controlled by the
fundamental engine parameters and components
(eq., carburation, ignition timing and port timing)
without addition of any major hardware or the
introduction of an inert material during
combustion.
• These engines are certified to operate on unleaded
gasoline.
• Make sure to use gasoline with a minimum octane
number of 89 RON (USA/Canada: 87AL)
• If you use a gasoline of a lower octane value than
prescribed, there is a danger that the engine
temperature may rise and an engine problem such
as piston seizing may consequently occur.
• Unleaded gasoline is recommended to reduce the
contamination of the air for the sake of your health
and the environment.
• Poor quality gasolines or oils may damage sealing
