U
S
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 RedMax
Professional-Commercial Duty, Hi-Performance, Hi-RPM, Air
Cooled 2-Stroke engines.
RedMax – 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 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

test standard has been discontinued by API in 1995 and it no
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
• 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.

■ AIR CLEANER
WARNING
• Never operate the blower without an air
filter or with a deformed or broken filter
element because unfiltered dusty air
will quickly ruin the engine.
• Check the air cleaner before use.
A clogged air filter may increase fuel
consumption while cutting down the
engine power.
• This prefilter is dry type.
• Never wash the prefilter in
oleaginous cleaning solution.
• Do not clean a paper filter by striking
it.
■ FUEL FILTER
• A clogged fuel filter may cause poor
acceleration of the engine. Check
periodically to see if the filter is clogged
with dirt. The filter can be taken out of
the fueling port using a small wire hook.
Disconnect the filter assembly from the
fuel pipe and unhook the retainer to
disassemble it. Clean the components
with gasoline.
• Never clean a paper filter by striking it
with or against another object. The filter
may be damaged and resultant dust
contamination can diminish engine
performance.

FEDERAL AND CALIFORNIA EMISSIONS CONTROL WARRANTY
STATEMENT YOUR WARRANTY RIGHTS AND OBLIGATIONS
U
S
The EPA (U.S. Environmental Protection Agency), CARB (California Air Resources Board), Environment
Canada and RedMax are pleased to explain the emissions control system's warranty on your 2009 and later
small off-road engine. In U.S. and Canada, new equipment that use small off-road engines must be designed,
built, and equipped to meet the applicable Federal or Californian stringent anti-smog standards. RedMax must
warrant the emissions control system on your small off-road engine for the period listed below provided there
has been no abuse, neglect or improper maintenance of your equipment. Your emissions control system may
include parts such as carburetor, ignition system, catalytic converter, fuel tank, filters and other associated
components. Also, included may be hoses, belts, connectors, sensors, and other emission-related assemblies.
Where a warrantable condition exists, RedMax will repair your small off-road engine at no cost to you including
diagnosis, parts and labor.
MANUFACTURER'S WARRANTY COVERAGE
This emissions control system is warranted for two years or if the product qualifies for a longer warranty period
resulting from the type of use, that period shall prevail. If any emissions-related part on your equipment is
defective, the part will be repaired or replaced by RedMax.
OWNER'S WARRANTY RESPONSIBILITIES
As the small off-road engine owner, you are responsible for performance of the required maintenance listed in
your Owner's Manual. RedMax recommends that you retain all receipts covering maintenance on your small off-
road engine, but RedMax cannot deny warranty solely for the lack of receipts or your failure to ensure the
performance of all scheduled maintenance. As the small off-road engine owner, you should however be aware
that the RedMax may deny you warranty coverage if your small off-road engine or a part has failed due to
abuse, neglect, or improper maintenance or unapproved modifications.
You are responsible for presenting your small off-road engine to a RedMax distribution center or service center
as soon as the problem exists. The warranty repairs should be completed in a reasonable amount of time, not to
exceed 30 days. If you have any questions regarding your warranty coverage, you should contact RedMax at 1-
800-291-8251 or via e-mail at [email protected].
WARRANTY COMMENCEMENT DATE
The warranty period begins on the date the engine or equipment is delivered to an ultimate purchaser.
LENGTH OF COVERAGE
RedMax warrants to the ultimate purchaser and each subsequent owner that the engine or equipment is
designed, built, and equipped so as to conform with all applicable regulations adopted by EPA and CARB, and
is free from defects in materials and workmanship that causes the failure of a warranted part for a period of two
years.
WHAT IS COVERED
REPAIR OR REPLACEMENT OF PARTS Repair or replacement of any warranted part under the warranty
must be performed at no charge to the owner at a warranty station. Warranty services or repairs will be provided
at all RedMax distribution centers that are franchised to service the subject engines. Throughout the emissions
warranty period of two years, RedMax must maintain a supply of warranted parts sufficient to meet the expected
demand for such parts.
WARRANTY PERIOD Any warranted part that is scheduled for replacement as required in the maintenance
schedule, is warranted for the period of time prior to the first scheduled replacement point for that part. If the
part fails prior to the first scheduled replacement, the part will be repaired or replaced by RedMax at no cost.
Any such part repaired or replaced under warranty is warranted for the remainder of the period prior to the first
scheduled replacement point for the part. Any warranted part that is not scheduled for replacement as required
in the maintenance schedule, is warranted for two years or if the product qualifies for a longer warranty period
resulting from the type of use, that period shall prevail. If any such part fails during the period of warranty
coverage, it will be repaired and replaced by RedMax at no cost. Any such part repaired or replaced under the
US-17
EBZ7150/RH
warranty is warranted for the remaining warranty period. Any warranted part that is scheduled only for regular
inspection in the maintenance schedule will be warranted for a period of two years. A statement in such written
instructions to the effect of "repair or replace as necessary" will not reduce the period of warranty coverage. Any
such part repaired or replaced under warranty will be warranted for the remaining warranty period.
DIAGNOSIS The owner must not be charged for diagnostic labor that leads to the determination that a
warranted part is in fact defective, provided that such diagnostic work is performed at a warranty station.
CONSEQUENTIAL DAMAGES RedMax is liable for damages to other engine components proximately caused
by a failure under warranty of any warranted part.

exempted add-on or modified parts will be grounds for disallowing a warranty claim. RedMax will not be liable to
warrant failures of warranted parts caused by the use of a non-exempted add-on or modified part.
