7. Fuel and chain oil
English
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 engines are lubricated by oil specially
formulated for air-cooled 2-cycle gasoline engine
use. If RedMax 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.
RECOMMENDED MIXING RATIO
GASOLINE 50:OIL 1
(when using ZENOAH genuine 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
rings, fuel lines or fuel tank of the engine.
