• 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)

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 90
ROZ(USA/Canada : pump octane min.87)

WARNING

• 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

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
again for at least one minute.

5. Put a clear indication on the outside of the
container to avoid mixing up with gasoline
or other containers.

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 dustless place.

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.

1. Select 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.

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 or
WATER COOLED 2-CYCLE ENGINE
USE – It can cause spark plug fouling,
exhaust port blocking, or piston ring
sticking.

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.

RESTARTING ENGINE WHILE ENGINE IS HOT

1. When restarting the engine immediately
after stopping it, leave the choke open.

2. If the engine won't start after several
attempts, close the choke and repeat
pulling the rope or remove the spark plug
and dry it.

■STOPPING ENGINE

Move the throttle lever to the idling position
and press the stop switch (red button) until
the engine comes to a complete stop.

Except for an emergency, avoid stopping the
engine while pulling the throttle lever.

■ADJUSTING IDLE SPEED

1. When the engine tends to stop frequently
at an idle mode, turn the adjusting screw
clockwise.

Warm up the engine before adjusting the idle
speed.

NOTE

NOTE

■STARTING ENGINE

1. Rest the unit on a flat, firm place.

2. Pump the primer until fuel flows out in the
clear tube.

3. Move the choke lever upward to close the
choke.

4. Holding the blower handle, pull the starter
rope with your right hand. (Throttle lever in
idling position.)

Avoid pulling the rope to its dead end or
returning it by releasing the knob. Such
actions can cause starter failures.

5. When the engine has started, move the
choke lever gradually downward to open
the choke.

6. Allow the engine to warm up for a half
minute before starting operation.

NOTE

Operation

■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 .025in.(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 CMR7A.

•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

• C h e c k 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. Place the filter
element into the air cleaner housing and
press the cover against the housing until it
clicks. Never forget to attach the screen. If
the screen is not attached, the cleaner will
not seal properly and the dusts come into
the cylinder.

WARNING

Maintenance

❲11❳

❲12❳

■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 two bolts to the cylinder. (Fastening
Torque: 70~110kg·cm)

•Even if one bolt out of three bolts is loose,
the muffler may get loose during operation
which 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 Public Resources Code) to equip
a spark arrester when a gas powered tool
is used in any forest covered, brush
covered, or grass covered unimproved
land.

IMPORTANT

■AIR INLET SCREEN

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

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

•Never use the blower without the screen
at the air intake of the blower. Before
each use, check that the screen is
attached in place and is free from any
damage.
