WARNING
5

6
•Keep operation area clear of all persons,
particularly small children and pets. Injury
may result from flying debris.
•Avoid using the blower where stable footing
and balance are not assured.
•Never 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 touch the muffler, spark plug, or
other metallic parts of the engine while the

serious burns.
■AVOID NOISE PROBLEM
Check and follow the local regulations
as to sound level and hours of
operations for blower.
•In general, operate blowers between
8a.m.and 5p.m.on week day and 9a.m.to
5p.m.weekends. Avoid using blower late at
night and/or early in the morning.
•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 attachement when
water is available.
•Check if the air filter, air intakes and muffler
are working in properly.
•Never use more than one piece of the
blower at a time.
■AVOID CHANCES OF DAMAGE
•Avoid directing the blower nozzle toward
persons, pets, cars, windows or anything
that could be harmed by blowing debris or
dust.
•Keep the nozzle at full extension when
operating so as to make the air stream
close to the ground.
•Collect any trash and leaves and put them
into a proper container after the job is
done.
•Always check to be sure that no debris has
been blown onto someone else’s property.

•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 spot
before starting the engine.
■FUEL MIX
•The engine is lubricated by oil mixed into
gasoline. Prepare a mixture of unleaded,
alcohol-free gasoline and RedMax oil or an
anti-oxidant added quality oil expressly
labeled for air-cooled 2-cycle engine use.
Recommended mixing ratio is 32 : 1.
•Make sure to use gasoline with a minimum
octane number of 90 ROZ(USA/Canada :
pump octane min.87)
•Unleaded gasoline is recommended to
reduce the contamination of the air for the
sake of your healths and the environment.
•Disqualified gasoline or oil may damage
sealing rings, fuel lines or fuel tank of the
engine.
•Exhaust emission are controlled by the
fundamental engine parameters and
components (eq., carburetion, ignition
timing and port timing) without addition
of any major hardware or the introduc-
tion of an inert material during combus-
tion.
WARNING
•These engines are certified to operate
on unleaded gasoline.
■MIXING FUEL
1.Measure out the quantities of gasoline and
oil to be mixed.
2.Put some of the gasoline into a clean,
marked fuel container.
3.Pour in all of the oil, cap the container and
shake it well.
4.Pour in the rest of gasoline and shake
again for one minute.
5.Indicate the contents on outside of
container to prevent with other containers.
DO NOT USE :
•Fuel containing no oil (raw gasoline)
may cause the engine becoming
overheated and damaged.
•Gasohol may cause deterioration of rubber
and plastic parts and disruption of the
engine lubrication.
•Oil for 4-cycle engine use or water-
cooled 2-cycle engine use may cause
spark plug fouling, carbon building-up and
piston ring sticking.
•Mixed fuels which have been left unused
for a period of one month or more may
have the carburetor clogged or result in the
engine failing to operate properly.
■FUELING
1.Unfasten and remove the fuel cap. Put the
cap on a clean surface for dirt prevention.
2.Pour fuel into the fuel tank up to 80% of full
capacity.
3.Replace the fuel cap and tighten securely.
Spilled fuel must be wiped away from the
blower before starting the engine.

■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.
■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.
•Plug manufacturers recommend replacing
the plug twice a year to avoid unexpected
plug failure in a job.
REPLACEMENT PLUG IS A CHAMPION
RCJ6Y.
•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.
IMPORTANT
•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
•Check the air cleaner every 25 hours of
use or more frequently if used under dusty
conditions. A clogged air filter may increase
fuel consumption while cutting down the
engine power. Never operate the blower
without the air filter or with a deformed filter
element because unfiltered dusty air will
quickly ruin the engine.
CLEANING AIR FILTER:
1.Remove the air cleaner cover by pulling
the tab on bottom and take out the filter
element.
2.Use neutral detergent and warm water to
clean the filter element. After cleaning, air
dry the element completely and moisten
with a small amount of motor oil.
3.Place the filter element into the air cleaner
housing and press the cover against the
housing until it clicks.
