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.  
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.

WARNING  
• Pay attention to agitation.  
1. Measure out the quantities of gasoline and oil to be mixed.  
2. Put some of the gasoline into a clean, approved fuel container.  
3. Pour in all of the oil and agitate well for 10seconds.  
4. Pour in the rest of gasoline and agitate again for at least one  
minute. As some oils may be difficult to agitate depending on oil  
ingredients, sufficient agitation is necessary. Be careful that, if  
the agitation is insufficient, there is an increased danger of early  
piston seizure due to abnormally lean mixture.  
5. Place a clear indication on the outside of the container to avoid  
mixing up with gasoline or other containers that dont contain oil.  
6. Indicate the contents on outside of container for easy  
identification.  
FUELING THE UNIT

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

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

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.
