WARNING
NOTE
• 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 10 ft (3 m) away from
the fueling point before starting the engine.
• Failures caused by operating engines on gasoline with octane
rating lower than 89 are not covered by the RedMax Two-
Stroke engine warranty.
WARNING
• Alternative Fuels (Not Gasoline)
Alternative fuels, such as E-15 (15% ethanol), E-20 (20%
ethanol), E-85 (85% ethanol) are NOT classified as gasoline
and are NOT approved for use in RedMax 2-stroke gasoline
engines. Use of alternative fuels will cause major engine
performance and durability problems such as: improper
clutch engagements, overheating, vapor lock, power loss,
lubrication deficiency, deterioration of fuel lines, gaskets
and internal carburetor components, etc... Alternative fuels
cause high moisture absorption into the fuel/oil mixture
leading to oil and fuel separation.
■ GASOLINE REQUIREMENTS
• All 2-Stroke RedMax Products are powered by Zenoah
Professional-Commercial Duty, Hi-Performance, Hi-RPM, Air
Cooled 2-Stroke engines.
RedMax/Zenoah – Hi-Performance 2-stroke engines produce
higher HP outputs as compared to standard Home Owner Duty
or Light Commercial Duty production engines offered by most
manufacturers.
• 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.
• The RedMax/Zenoah Engines are registered and certified with
CARB (California Air Resources Board) and EPA
(Environmental Protection Agency) to operate on CLEAN Mid-
grade 89 octane or Premium, unleaded (lead-free) gasoline and
RedMax Air-Cooled "Max Life", Synthetic blend Premium two-
stroke engine oil mixed at 50:1 ratio.
■ OIL REQUIREMENTS
• Use only RedMax "Max Life", Synthetic blend Premium Air-
Cooled two-stroke engine oil or oil certified to ISO-L-EGD
(ISO/CD1378) standard AND one that is JASO-FD registered.
RedMax Air-Cooled "Max Life", Synthetic blend Premium two
stroke engine oil and ISO-L-EGD (ISO/CD1378) AND JASO-FD
oils are fully compatible with gasoline's containing 10% Ethanol.
RedMax Air-Cooled "Max Life", Synthetic blend Premium two
stroke engine oil and ISO-L-EGD (ISO/CD1378) AND JASO-FD
oils are Universal and should be mixed at 50:1 ratio for all 2
stroke air cooled engines sold in the past regardless of mixing
ratios specified in those manuals.
• Unleaded gasoline is recommended to reduce the
contamination of the air for the sake of your health and the
environment.
• If the oil is registered with JASO, the JASO Logo with FD and
registration number will be displayed on the container. The
highest JASO rating is "FD", which equals the ISO-L-EGD
rating. Lower ratings are "FC", "FB", and "FA".
• This Hi-Performance Air Cooled 2-stroke Engine requires the
[ R+M ]
use of Minimum 89 Octane
(Mid grade or Premium)
2
clean gasoline. Gasoline may contain maximum of 10% Ethanol
(grain alcohol) or up to 15% MTBE (Methyl tertiary-butyl ether).
Gasoline containing Methanol (Wood Alcohol) is NOT
approved.
NOTE
• Engine problems due to inadequate lubrication caused by
failure to use ISO-L-EGD certified and JASO FD registered oil
such as "MaxLife", RedMax Synthetic blend Premium 2-stroke
oil WILL VOID THE REDMAX TWO-STROKE ENGINE
WARRANTY.
• IF octane rating of the Mid Grade gasoline in your area is lower
than 89 Octane use Premium Unleaded Gasoline. The majority
of all 2-stroke engine manufacturers in the USA and Canada
recommend using gasoline with 89 Octane or higher.
WARNING
WARNING
• Gasoline with an octane rating lower than 89 will greatly
increase the engines operating temperature. Low octane
gasoline will cause detonation (knock) resulting in piston
seizures and major internal engine components damage.
• Poor quality gasolines or oils may damage sealing rings, fuel
• Do not use NMMA (National Marine Manufacturers
Association), BIA (Boating Industry Association), and TCW (two
cycle water cooled) oils designed for MoPeds or Outboard,
water cooled Marine Engines. Do not use API (American
Petroleum Institute), TC (Two Cycle) labeled oils. The API-TC

longer exists.
WARNING
1. Select flat and bare ground for fueling.
2. Move at least 10 feet (3 meters) away from the fueling point
before starting the engine.
3. Stop the engine before refueling the unit. At that time, be
sure to sufficiently agitate the mixed gasoline in the
container.
IMPORTANT
U
S
• Gasoline/Oil mixture Storage Recommendations
Store your gasoline or gasoline/oil mixture in a cool dry area in
a tightly sealed approved container to limit the entry of moisture
and additional air (oxygen). Moisture and air cause the
development of varnish and gum, making the fuel stale. Stored
gasoline and gasoline/oil mixture ages and loses its octane
rating and volatility. Do not mix more gasoline/oil than you
intend to use in 30 days, and 60 days when fuel stabilizer is
added. RedMax Air-Cooled "Max Life" Synthetic blend
Premium two-stroke engine oil "Contains fuel stabilizer" and
will automatically extend your gasoline/oil mixture life up to 60
days.
■ FOR YOUR ENGINE LIFE, AVOID
1. FUEL WITH NO OIL (RAW GASOLINE) – It will cause severe
damage to the internal engine parts very quickly.
2. GASOHOL – It can cause deterioration of rubber and/or plastic
parts and disruption of engine lubrication.
3. OIL FOR 4-CYCLE ENGINE USE – It can cause spark plug
fouling, exhaust port blocking, or piston ring seizure.
4. Mixed fuels which have been left unused for a period of
one month or more may clog the carburetor and result in the
engine failing to operate properly.
5. In the case of storing the product for a long period of time,
clean the fuel tank after rendering it empty. Next, Start the
engine and run the carburetor dry residual fuel.
6. In the case of scrapping the used mixed oil container, scrap it
only at an authorized depository site.

doing so could result in severe
burns.
• When checking the machine to make
sure that it is okay before using it,
check the area around the muffler
and remove any wood chips or
leaves which have attached
themselves to the machine. Failing
to do so could cause the muffler to
become overheated, and that this in
turn could cause the engine to catch
on fire. Always make sure that the
muffler is clean and free of wood
chips, leaves, and other waste
before use.
• Check the intake air cooling vent and
the area around the cylinder cooling
fins after every 25 hours of use for
blockage, and remove any waste which
has attached itself to the machine. Note
that it is necessary to remove the
engine cover shown in (MA8) in order
to be able to view the upper part of the
cylinder.
IMPORTANT
• If waste gets stuck and causes
blockage around the intake air cooling
