checking
The metallic parts reach high temperatures
immediately after stopping the engine.
3. When replacing the oil or any
lubricant, always be sure to u s e
o n l y RedMax products or
products which have been
certified by RedMax for use with
the RedMax product.
4. In the event that any part must be
replaced or any maintenance or
rough roads over long distances by
vehicle without removing all fuel
from the fuel tank. If doing so, fuel
might leak from the tank during
transport.
_ HANDLING FUEL
1. The engine of the RedMax product
is designed to run on a mixed fuel
which contains highly flammable
gasoline. Never store cans of fuel or
refill the tank of the unit in any place
where there is a boiler, stove, wood
fire, electrical sparks, welding
sparks, or any other source of heat
or fire which might ignite the fuel.
2. Never smoke while operating the
unit or refilling its fuel tank.
3. When refilling the tank, always turn
off the engine and allow it to cool
down. Take a careful look around to
make sure that there are no sparks
or open flames anywhere nearby
before refueling.
_ CONNECTING THROTTLE WIRE
1. Remove the air cleaner cover.
2. Connect the end of the throttle wire
to the joint on the top of the
carburetor. (SE7)
_ CONNECTING SWITCH WIRES
• Connect the switch wires between
the engine and mount. Connect the
wires: Black to Yellow and Red to
Green . (SE7)
4. Wipe spilled fuel completely using a
dry rag if any fuel spillage occurs
during refueling.
5. After refueling, screw the fuel cap
back tightly onto the fuel.
_ TRANSPORTATION

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
The RedMax engines are lubricated
by oil specially formulated for aircooled 2-cycle gasoline engine use.
If RedMax oil is not available, use
an anti-oxidant added quality oil
expressly labeled for air-cooled 2cycle engine use. (JASO FC
GRADE OIL or ISO EGC GRADE)

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)
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.
Fuel
_ 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.
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.
_ FUELING THE UNIT
1. Untwist and remove the fuel cap.
Rest the cap on a dustless place.
2. Put fuel into the fuel tank.
3. Fasten the fuel cap securely and
wipe up any fuel spillage around the
unit.
Operation
Starting the Engine
(1) Choke lever (2) On (3) Off
1. Push the primer pump several times until overflown fuel flows out in the clear tube. (OP1)
2. Move the choke lever to the ON position. (OP2)
3. Pull out the starter rope quickly until engine fires.

Operation
•
•
•
Avoid pulling the rope to its end or
returning it by releasing the knob.
Such actions can cause starter
failures.
Move the choke lever to the OFF
position and restart the engine
(OP2)
Allow engine to warm up for several
minutes.
1. When restarting the engine
immediately after stopping it, leave
the choke in the off position.
2. Over choking can make the engine
hard to start due to excess fuel.
_ ADJUSTING THROTTLE CABLE (OP5)
• The normal play is 1 or 2mm when
measured at the carburetor side
end. Readjust with the cable
adjuster as required. (OP5)

Maintenance
_ AIR FILTER
• The air filter, if clogged, will reduce
the engine performance. Check and
clean the filter element in warm,
soapy water as required. Dry
completely before installing. If the
element is broken or shrunk, replace
with a new one. (MA5)
(1) air filter
•
•
_ FUEL FILTER
• When the engine runs short of fuel
supply, check the fuel cap and the
fuel filter for blockage. (MA6)
(1) fuel filter
_ SPARK PLUG
• Starting failure and mis-firing are
often caused by a fouled spark plug.
Clean the spark plug and check that
the plug gap is in the correct range.
For a replacement plug, use the
correct type specified by RedMax.
(MA7)
• REPLACEMENT PLUG IS A NGK
CMR7A.
• Note that using any spark plug other
than those designated may result in
the engine failing to operate
properly or in the engine becoming
overheated and damaged, and void
your warranty.
• 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.
TIGTENING TORQUE:
Inspect periodically, the muffler for
loose fasteners, any damage or
corrosion. If any sign of exhaust
leakage is found, stop using the
machine and have it repaired
immediately.
Note that failing to do so may
result in the 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. Using
needle nose pliers, pull spark
arrester to remove, push to reinstall
after cleaning. 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. (MA8)

Maintenance
•
_ INTAKE AIR COOLING VENT
•
•
•
Never touch the cylinder, muffler,
or spark plugs with your bare
hands immediately after stopping
the engine. The engine can
become very hot when in
operation, and doing so could
result in severe burns.
When checking the machine to
make sure that it is okay before
using it, check the area around
the muffler and remove any
debris. Failing to do so could
cause the muffler to become
overheated, and that this in turn
could cause the engine to catch
on fire. Always make sure that the
muffler is clean and free of
debris.
Check the intake air cooling vent
and the area around the cylinder
cooling fins after every 25 hours of
use for blockage, and remove any
waste which has attached itself.
Note that it is necessary to remove
the engine cover shown in (MA10)
in order to be able to view the upper
part of the cylinder.
If waste gets stuck and causes
blockage around the intake air
cooling vent or between the cylinder
fins, it may cause the engine to
overheat, and that in turn may
cause mechanical failure. (MA10)
(1) cylinder
(2) intake air cooling vent (back)
_ (MA11) 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.
3. Check to see if any oil or grease has
worked its way in between the
clutch lining and drum, and if it has
wipe it away using oil-free, lead-free
gasoline.

Storage
Aged fuel is one of major causes of engine starting failure. Before storing the unit, empty
the fuel tank and run the engine until it uses all the fuel left in the fuel line and the
carburetor. Store the unit indoor taking necessary measures for rust prevention.
