WARNING

FUEL

• 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.

■ 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 Mid­grade 89 octane or Premium, unleaded (lead-free) gasoline and
RedMax Air-Cooled "Max Life", Synthetic blend Premium two­stroke engine oil mixed at 50:1 ratio.

• Unleaded gasoline is recommended to reduce the
contamination of the air for the sake of your health and the
environment.

• This Hi-Performance Air Cooled 2-stroke Engine requires the
use of Minimum

89 Octane (Mid grade or Premium)

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.

• 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.

• 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

7. Fuel

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

• 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.

■ HOW TO MIX FUEL

RECOMMENDED MIXING RATIO
GASOLINE 50 : OIL 1
(when using RedMax Air-Cooled "Max
Life")

• 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

1. Untwist and remove the fuel cap. Rest the cap on a clean
surface.

2. Put fuel into the fuel tank to 80% of the full capacity.

3. Fasten the fuel cap securely and wipe up any fuel spillage
around the unit.

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.

■ 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.

Maintenance, replacement, or repair of the emission control device and
systems may be performed by any non-road engine repair establishment or
individual.

9. Maintenance

Make sure that the engine has stopped
and is cool before performing any
service to the blower. Contact with
rotating blower fan or hot muffler may
result in a personal injury.

■ AIR CLEANER

• 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.

• 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.

CLEANING AIR FILTER:

1. Unscrew 2 knob bolts and remove the
air cleaner cover. Then remove a
prefilter mounted inside the air cleaner
cover.

■ SPARK PLUG

• The spark plug may gather carbon
deposits on its firing end with
reasonable use. Remove and inspect
the spark plug every 25 hours and
clean the electrodes as necessary with
a wire brush. The spark gap should be
adjusted to .025 in (0.6~0.7mm).

• Plug manufacturers recommend
replacing the plug twice a year to avoid
unexpected plug failure in a job.

REPLACEMENT PLUG IS A NGK
CMR7H.

• Note that using any spark plugs other
than those designated may result in the
engine failing to operate properly or in
the engine becoming overheated and
damaged.

• To install the spark plug, first turn the
plug until it is finger tight, then tighten it
a quarter turn more with a socket
wrench.

■ MUFFLER

• Inspect periodically, the muffler for
loose fasteners, any damage or
corrosion. If any sign of exhaust
leakage is found, do not use the blower
and have it repaired immediately.

• Note that failing to do so may result
in the engine catching on fire.

• Before starting operation, always make
sure to check if the muffler is properly
held by three bolts (F21 (2)).
(Fastening Torque : 8 to 12 N·m)

• Also make sure that the speak arrester
and the diffuser are properly attached
with four bolts (F21 (1)). (Fastening
Torque : 2 to 3 N·m)

• Even if one of seven bolts is loose, it
may result in engine catching on fire.

■ SPARK ARRESTER

• The muffler is equipped with a spark
arrester to prevent red hot carbon from
flying out of the exhaust outlet.
Periodically inspect and clean as
necessary with a wire brush. In the
State of California it is required by law
(Section 4442 of the California Pulic
Resources Code) to equip a spark
arrester when a gas powered tool is
used in any forest covered, bush
covered, or grass covered unimproved
land.

■ PROCEDURES TO BE PERFORMED
AFTER EVERY 100 HOURS OF USE

1. Remove the muffler, insert a
screwdriver into the vent, and wipe
away any carbon buildup. Wipe away
any carbon buildup on the muffler
exhaust vent and cylinder exhaust port
at the same time.

2. Tighten all screws, bolts, and fittings.

■ AIR INLET NET

• Blowing air is taken in from the air inlet
net. When air flow has dropped down
during operation, stop the engine and
inspect the air inlet net for blocking by
obstacles.

• Note that failure to remove any such
obstacles may result in the engine
becoming overheated and damaged.

(1) Net

Never use the blower without the net of
the blower. Before each use, check
that the net is attached in place and is
free from any damage.

■ IGNITION COIL AIR GAP
INSPECTION

• If the gap is out of standard or when
installing the coil or rotor, adjust the air
gap between the ignition coil and the
iron core of the rotor.

Air Gap:

0.40mm (0.35 ~ 0.45mm)

0.016" (0.014 ~ 0.017")
