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

•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

4

•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.

•Drain the fuel from the fuel tank before

transporting or storing the blower.

•When storing the blower, choose a space

indoors free from moisture and out of the

reach of children.

•Examine the blower at intervals for loose

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.

Fuel

10 

■RECOMMENDED MIXING RATIO

GASOLINE 50:OIL 1

(When using RedMax/ZENOAH genuine oil)

•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.

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.
