•Read this Blower Owner/Operator Manual
carefully. Be sure you understand how to
operate this unit properly before you use
it. Failure to do so could result in serious
injury.
•Be sure to keep this manual handy so that
you may refer to it later whenever any
questions arise. Also note that you are
requested to contact the dealer from
whom you purchased the product for
assistance the event that you have any
questions which cannot be answered

transferring the ownership of this product.
■OPERATOR
•Refrain from operating the blower if you are
tired, ill, or upset, or if you are under the
influence of alcohol, drugs or medication.
•To reduce the risk of hearing loss
associated with sound level(s), hearing
protection is required.
•Always wear eye protection and foot
protection. Eye protection should meet
the requirements of ANSI Z87.1.
•To reduce the risk of injury associated with
the inhalation of dust, use a face filter mask
in dusty conditions.
•Wear rubber-soled shoes or shoes with
WARNING
Safety Precautions
some other form of anti-slip protection to
help protect you against falling.
•To reduce the risk of injury associated with
objects being drawn into rotating parts, do
not wear loose clothing, scarves, neck
chains, unconfined long hair, and the like.
■USE OF BLOWER
•Each time before starting the engine,
inspect the entire unit to see if every part is
in good order and is securely tightened in
place. If any damage is found in the fuel
line, the exhaust line, or the ignition wiring,
do not use the blower until it has been
repaired.
•Before starting operation, always make
sure to check if any obstacles are left
inside the volute case. The obstacles may
cause damage on fan and volute case and
serious injury.
Check to see if the shock-absorbing rubber
mount has become cracked or otherwise
damaged. Note that failing to replace this
rubber mount when it has become
cracked or damaged may cause the
engine to come loose from its frame
during use, thus resulting in possible
serious bodily injury.
•If cracked, be sure to replace without delay.
WARNING
IMPORTANT

•To reduce the risk of injury associated with
contacting rotating parts, stop the engine
before installing or removing attachments.
Do not operate without net in place.
Always disconnect the spark plug before
performing maintenance or accessing
movable parts.
•Do not allow children to use blower. Make
sure that each person you authorize to
operate the blower understands all of the
safety rules in this manual.
•Avoid using any accessory or attachment
other than those bearing the RedMax mark
for use with the blower.

fasteners and rusted or damaged parts.
Use special care around the fuel line, the
muffler, and the ignition wiring.
•All engine service except for those
described in this manual should be
performed by competent service personnel.
Improper service to the blower fan and
muffler could cause a hazardous failure.
WARNING
Safety Precautions
■FUEL
To reduce the risk of fire and burn injury:
•Handle fuel with care. It is highly
flammable.
•Do not smoke while handing fuel.
•Do not refuel a hot engine.
•Do not refuel a running engine.
•Avoid spilling fuel or oil. Always wipe unit
dry before using.
•Move at least 10 ft. (3 meters) away from
the fueling point before starting engine.
•Always store gasoline in a container
approved for flammable liquids.
•Make sure the unit is properly assembled
and in good operating condition.
■WORKING CONDITION
•Check the work area that the blower will be
used in and remove or cover all valuables
that may be damaged by the air blast or
thrown debris.
•To reduce the risk of injury associated with
exhaust fume inhalation, do not operate in
unventilated area. The exhaust gases
contain harmful carbon monoxide.
•Do not allow bystanders in work area.
•Do not point the blower nozzle in the
direction of people or pets.
WARNING
5
•Avoid using the blower where stable footing
and balance are not assured.
•Never to touch the spark plug or plug cord
while the engine is in operation. Doing so
may result in being subjected to an
electrical shock.
•Never to touch the muffler, spark plug, or
other metallic parts of the engine while the
engine is in operation or immediately after
shutting down the engine. These metallic
parts reach high temperatures during
operation and doing so could result in
serious burns.
■AVOID NOISE PROBLEM
Check and follow the local regulations
as to sound level and hours of
operations for blower.
•Operate power equipment only at
reasonable hours-not early in the morning
or late at night when people might be
disturbed. Comply with times listed in local
ordinances.
•To reduce sound levels, limit the number of
pieces of equipment used at any one time.
•Operate power blowers at the lowest
possible throttle speed to do the job.
•Check your equipment before operation,
especially the muffler, air intakes and air
filters.
•Loosen compacted leaves, grass or debris
with a rake or broom beforehand, so that
the lowest possible throttle setting would
get the job done.
•In dusty conditions, slightly dampen
surfaces or use mister attachment when
water is available.
■AVOID CHANCES OF DAMAGE
•Watch out for children, pets, open windows
or freshly washed cars, and blow debris
safely away.
•Use the full blower nozzle extension so the
air stream can work close to the ground.
•After using blowers and other equipment,
CLEAN UP! Dispose of debris in trash
receptacles.
•Always check to be sure that no debris has
been blown onto someone else’s property.

■RECOMMENDED MIXING RATIO
GASOLINE 50:OIL 1
•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.
■HOW TO MIX FUEL
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.
4. Pour In the rest of gasoline and agitate
IMPORTANT
•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.
