INFORMATION
This machine is equipped with an Overload Cancellation
Mechanism.
When the cutting blades have got into metal wires or those
twigs difficult to cut, the mechanism acts as a shock
absorber, and protects the drive gears and the blades from
severe reaction which could give damage to those parts.
When the blades are frequently caught by twigs, please
check the following points:
1. Size of the twigs. NEVER TRY TO CUT TWIGS
THICKER THAN 3/16”.
2. Condition of the blade edges. REPLACE THE WORN
OUT BLADES.
For the detail of the mechanism, please see below.
Thank you for choosing our product.

assistance in the event that you have any
questions which cannot be answered
herein.
• Always be sure to include this manual
when selling, lending, or otherwise
transferring the ownership of this product.
• This product has been designed for use in
trimming leaves and branches from trees
and hedges, and it should never be used
for any other purpose since doing so could
result in unforeseen accidents and injuries
occurring.
• This product is equipped with extremely
sharp blades, and when used improperly
these blades can be extremely dangerous.
For this reason, you should never use this
trimmer when under the influence of
alcohol, when suffering from exhaustion or
lack of sleep, when suffering from
drowsiness as a result of having taken cold
medicine, or at any other time when a

Safety Precautions
■Work gear and clothing
• When using your trimmer, always be sure
to wear strong, durable, work clothing;
shirts should be long-sleeved shirts and
pants should be full-length pants reaching
down to the ankles.
• Always be sure to wear and helmet and
face protector when using your trimmer.
• When using your trimmer, always be sure
to wear thick work gloves to protect your
hands and non-slip-sole work boots to
prevent you from slipping. Never use your
trimmer when wearing pants with loose
cuffs, when wearing sandals, or when
barefoot.
• When using your trimmer for an extended
period of time, you should wear ear
protectors to protect yourself from loss of
hearing from overexposure to high levels of
sound.
■Warnings considering handling of fuel
• The engine of the RedMax® trimmer is
designed to run on a mixed fuel which
contains highly flammable gasoline. This
fuel is highly flammable and you should
never store cans of fuel or refill the tank of
the trimmer in any place where there is a
boiler, stove, wood fire, electrical sparks,
welding sparks, or any other source of heat

open flames anywhere nearby before
refueling.
• If any fuel spillage occurs during refueling,
always be sure to use a dry rag to wipe any
fuel which has been spilled onto the
trimmer before turning the engine back on
again.
• After refueling, screw the fuel cap back
tightly onto the fuel tank and then carry the
trimmer to a spot 10 feet or more away
from where it was refueled before turning
on the engine.
❲5❳
Safety Precautions
■ Things to check before using your
trimmer
•Before beginning work, look around
carefully to get a feel for the shape of the
land, the trees, hedges, or bushes to be
trimmed, and whether or not there are any
obstacles which might get in the way while
working, and remove any obstacles which
can be cleared away before beginning
work.
•The area within a perimeter of 45 feet of the
person using the trimmer should be
considered a hazardous area into which no
one should enter while the trimmer is in
use, and when necessary yellow warning
rope, warning signs, or some other form of
warnings should be placed around the
perimeter of the area. When work is to be
performed simultaneously by two or more
persons, care should also be taken to
constantly look around or otherwise check
for the presence and locations of other
people using trimmers within the work area
so as to maintain a distance between each
person sufficient to ensure safety.
•Before beginning work, each component of
the trimmer should be checked to make
sure that it is in proper working order and to
make sure that there are no loose screws
or bolts, fuel leaks, ruptures, dents, or any
other problems which might interfere with
safe operation. Be especially careful at this
time to check that there is nothing wrong
with the blades or with the joints by which
the blades are attached to the trimmer.
• Never use the trimmer when the blades
have been worn down severely or when
there is any sort of damage which has
occurred to the blade mechanism.
• Check to make sure that the handle grip
and the protective cover have not come
loose before using the trimmer.
■ Things to check before starting up the
engine
• Take a careful look around to make sure
that no obstacles exist within a perimeter of
15 feet or less around the trimmer before
starting the engine.
• The RedMax trimmer is equipped with a
centrifugal clutch mechanism which causes
the cutting blades to begin to rotate as
soon as the engine is started by putting the
throttle into the start position. When starting
the engine, place the body of the trimmer
onto the ground in a flat clear area and
hold it firmly in place so as to ensure that
neither the blades nor the throttle come into
contact with any obstacles when the engine
starts up.
•Never place the throttle into the high speed
position when starting the engine.
•After starting up the engine, check to make
sure that the blades stop rotating when the
throttle is moved fully back to its original
position. If the blades continue to rotate
even after the throttle has been moved fully
back, turn off the engine and take the unit
to your authorized Red Max servicing
dealer for repair.
■AVOID NOISE PROBLEM
Check and follow the local regulations
as to sound level and hours of
operations for long reach trimmer.
• In general, operate trimmers between
8a.m.and 5p.m.on week days and 9a.m.to
5p.m.weekends. Avoid using trimmer late
at night and/or early in the morning.
NOTE
Safety Precautions
■ Things to be careful about when using
your trimmer
•When using your trimmer, grip the handles
of the trimmer firmly with both hands, place
your feet slightly apart (slightly further apart
than the width of your shoulders) so that
your weight is distributed evenly across
both legs, and always be sure to maintain a
steady, even posture while working.
• Maintain the speed of the engine at the
level required to perform trimming work,
and never raise the speed of the engine
above the level necessary.
• Always be sure never to allow other
persons to come within the work area while
trimming, as doing so might expose them
to the danger of being hit by falling
branches as they are cut.
• Be especially careful not to slip if it is
raining or if rain has just stopped, as the
ground is likely to be slippery at such times.
• If a branch or other object gets caught in
the blades during operation, always be
sure to turn off the engine before removing
the object.
• To protect yourself against injury from
falling branches, always be sure to wear
the required safety equipment, and be
careful when working to watch to see in
which direction branches are moving and
falling so as to avoid being hit by falling
branches.
•If someone calls out or otherwise interrupts
you while working, always be sure to turn
off the engine before turning around.
• Keep operation area clear of all persons,
particularly small children and pets. Injury
may result from flying debris.
• 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 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.
• When you finish trimming in one location
and wish to continue work in another spot,
turn off the engine, place the protective
cover over the blades, and turn the trimmer
so that the blades face away from your
body before carrying it to the new location.
• Never transport the trimmer over rough
roads over long distances without first
removing all fuel from the fuel tank, as
doing so might cause fuel to leak from the
tank as a result of shocks absorbed during
transport.
■ Notes on care and maintenance of your
trimmer
•In order to maintain your trimmer in proper
working order, perform the maintenance
and checking operations described in this
manual at regular intervals. In the event
that any parts must be replaced or any
maintenance or repair work not described
in this manual must be performed, please
contact a representative from the store
nearest RedMax authorized servicing
dealer for assistance.
• Under no circumstances should you ever
take apart the trimmer or alter it in any way.
Doing so might result in the trimmer
becoming damaged during operation or the
trimmer becoming unable to operate
properly.
•Always be sure to turn off the engine before
performing any maintenance or checking
procedures.
•When sharpening, removing, or reattaching
the blades, be sure to wear thick, sturdy
gloves and use only proper tools and
equipment to prevent injury.
• When replacing blades or any other parts
or when replacing the oil or any lubricants,
always be sure to use only RedMax
products or products which have been
certified by RedMax for use with the
RedMax trimmer.

Maintenance
■BLADES
•When refilling the tank or resting, it is often
a good idea to use the time to oil the
cutting blades.
•If a gap exists between the upper and lower
blades, follow the procedure below to
adjust them so that they fit more closely
together.
1. Loosen lock nut (A) as shown in the
diagram.
2. Tighten screw (B) fully, and then turn
one-third to one-half of a rotation
backward.
3. While holding onto the screw to keep it
in position, tighten the lock nut.
4.Check to make sure that the flat washer
(C) is loose enough so that it may be
turned by pressing on it with a finger.
Screwing in the screw too tightly may make
it impossible for the blades to move.
Conversely, not screwing in the screw tightly
enough may make the blades of the trimmer
feel dull and cause leaves and branches to
become caught in the blades of the trimmer.
QUICK TIP
If the blades become so worn down that it is
no longer possible to eliminate the gap
between them, you should contact the
authorized RedMax servicing dealer from
which you purchased your RedMax®
trimmer to have the blades resharpened or
replaced.
NOTE
■GEAR CASE
The inside of the gear case should be
lubricant using ZENOAH-approved lubricant
after every 20 hours of use.
When adding lubricant, use a grease gun to
insert lubricant into the three grease nipples
located on the gear case.
TYPE OF LUBRICANT TO BE USED
Always be sure to use #2 lithium
heat-resistant lubricant.
■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 OR THE EQUIVALENT, SUCH AS
BOSCH WR8E OR NGK BR6S.
•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 trimmer. Contact with
moving cutting head 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 trimmer
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

■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 trimmer to make
sure that it is okay before using it,
check the area around the muffler and
remove any wood chips or leaves which
have attached themselves to the
trimmer. Note that failing to do so could
cause the muffler to become
overheated, and that this in turn could
cause the trimmer to catch on fire.
Always make sure that the muffler is
clean and free of wood chips, leaves,
and other waste before use.
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
to the trimmer. Note that it is necessary to
remove the plug guard shown in Figure 20 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 on the part of the
trimmer.
IMPORTANT
■ 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 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.
WARNING
Storage
BEFORE STORING THE TRIMMER
1.Drain a fuel tank and push the primer bulb
until it becomes empty of fuel.
2.Remove the spark plug and drop a
spoonful of 2-cycle oil into the cylinder.
Pull the starter rope several time and
replace the plug.

Maintenance
■MUFFLER
• Inspect periodically, the muffler for loose
fasteners, any damage or corrosion. If any
sign of exhaust leakage is found, do not
use the trimmer and have it repaired
immediately.
• Note that failing to do so may result in
the engine catching on fire.
WARNING
■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.
