IN ORDER TO ENSURE PROPER AND SAFE

OPERATION OF YOUR HEDGE-TRIMMER

•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

hedge-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

possibility exists that your judgment might

be impaired or that you might not be able to

operate the hedge-trimmer properly and in

a safe manner. Also be sure never to allow

children or anyone unable to fully

understand the directions given in this

manual to use this hedge-trimmer.

Safety Precautions

•Avoid running the engine indoors. The

exhaust gases contain harmful carbon

monoxide.

•Never use your hedge-trimmer under

circumstances like those described below:

1.When the ground is slippery or when

other conditions exist which might make

it not possible to maintain a steady

posture while using the hedge-trimmer.

2.At night, at times of heavy fog, or at any

other times when your field of vision

might be limited and it would be difficult

to gain a clear view of the area where

the hedge-trimmer is to be used to

ensure safety.

3.During rain storms, during lightning

storms, at times of strong or gale-force

winds, or at any other times when

weather conditions might make it unsafe

to use this product.

•When using this product for the first time,

before beginning actual work, take the

hedge-trimmer to a wide, clear, open

space, turn on the power, and practice

handling the hedge-trimmer until you are

sure that you will be able to handle in it

properly in actual operation.

•Lack of sleep, tiredness, or physical

exhaustion results in lower attention spans,

and this in turn leads to accidents and

injury. When planning your work schedule,

allow plenty of time to perform the work of

trimming and allow plenty of time for rest.

Limit the amount of time over which the

hedge-trimmer is to be used continuously

to somewhere around 30~40 minutes per

session, and take 10~20 minutes of rest

between work sessions. Also try to keep

the total amount of work performed in a

single day under 2 hours or less.

•Read this Owner/Operator Manual

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 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.

Safety Precautions

■WORK GEAR AND CLOTHING

•When using your hedge-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 hedge-

trimmer.

•When using your hedge-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

hedge-trimmer when wearing pants with

loose cuffs, when wearing sandals, or

when barefoot.

•When using your hedge-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 hedge-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 hedge-trimmer 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.

•Smoking while operating the hedge-trimmer

or refilling its fuel tank is extremely

dangerous. Always be sure to keep lit

cigarettes away from the hedge-trimmer at

all times.

•When refilling the tank always turn off the

engine first and take a careful look around

to make sure that there are no sparks or

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 hedge-

trimmer before turning the engine back on

again.

•After refueling, screw the fuel cap back

tightly onto the fuel tank and then carry the

hedge-trimmer to a spot 10 feet or more

away from where it was refueled before

turning on the engine.

Safety Precautions

■

THINGS TO CHECK BEFORE USING YOUR

HEDGE-TRIMMER

•Before beginning work, look around

carefully to get a feel for the shape of the

land, the trees, or hedges 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 50 feet

(15m) of the person using the hedge-

trimmer should be considered a hazardous

area into which no one should enter while

the hedge-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 hedge-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 hedge-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

hedge-trimmer.

•Never use the hedge-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 hedge-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 (5m) or less around the hedge-

trimmer before starting the engine.

•The RedMax hedge-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

hedge-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 RedMax servicing dealer

for repair.

■AVOID NOISE PROBLEM

Check and follow the local regulations

as to sound level and hours of

operations for hedge-trimmer.

•In general, operate hedge-trimmers

between 8a.m.and 5p.m.on week days and

9a.m.to 5p.m.weekends. Avoid using

hedge-trimmer late at night and/or early in

the morning.

NOTE

•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 hedge-

trimmer so that the blades face away from

your body before carrying it to the new

location.

•Never transport the hedge-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.

Safety Precautions

■

THINGS TO BE CAREFUL ABOUT WHEN

USING YOUR HEDGE-TRIMMER

•When using your hedge-trimmer, grip the

handles of the hedge-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.

•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.

•Guard against hazardous situations at all

times. Warn adults to keep pets and

children away from the area. Establish a

safe method for gaining your attention

during operation. Be careful if you are

approached.

•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.

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 hedge-trimmer or alter it in

any way. Doing so might result in the

hedge-trimmer becoming damaged during

operation or the hedge-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,

available. Use an anti-oxidant added

quality oil expressly labeled for air-cooled

2-cycle engine use.

RECOMMENDED MIXING RATIO

GASOLINE 32: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)

•Unleaded gasoline is recommended to

reduce the contamination of the air for the

sake of your health and the environment.

•Avoid pulling the rope to its end or returning

it by releasing the knob. Such actions can

cause starter failures.

5.When the engine has started, gradually

open the choke.

6.Allow the engine to warm up for a half

minute before starting operation.

•If the engine won't start after several

attempts, open the choke and repeat

pulling the rope or remove the spark plug

and dry it.

■ STOPPING ENGINE

1.Release the throttle lever and run the

engine at idling speed for a half minute.

2.Stop the engine by the stop switch.

Operation

■ ADJUSTING IDLING SPEED

1.When the engine tends to stop frequently

at idling mode, turn the idle set screw

clock-wise.

2.When the cutting blades keep moving after

releasing the throttle trigger, turn the idle

set screw counter-clockwise.

•Warm up the engine before adjusting the

idling speed.

NOTE

■ HOW TO USE

•This machine is designed so as to cut

twigs upto 8 mm(0.3 inches) thick.

Cutting too thick twigs or metal wires

can not only break the blade teeth but

also give damage to the drive

mechanism.

•When trimming leaves and thin twigs, guide

the blades as drawing a half circle on the

surface, and you will get a better finish.

•Running the engine at high speed with the

blades Jammed up can shorten the life of

clutch parts. When the blades have been

jammed by thick twigs, stop operation at

once and draw your unit off the objects

after stopping the engine. When clipping

comparatively thick twigs, move your unit

slowly back and forth like a saw, and they

can be cut to fine finish.

•When a new unit is first operated, in the

first few minutes grease may come out of

the gear case. But, since this is excess

grease, there is no cause for alarm. For

next use just wipe it off with the engine

stopped.

NOTE

❲

❳

❲

❳

Maintenance

•Make sure that the engine has stopped

and is cool before performing any

service to the hedge-trimmer. Contact

with moving cutting head or hot muffler

may result in a personal injury.

■ DAILY INSPECTION

•Check all the fasteners for loose or missing

ones.

•Brush off dirt on the blades and apply a

light coating of oil.

•The blades are loose-installed to the guide

bar with several screws and nuts. Do not

tighten up those screws, or the blades will

be locked and result in clutch failures.

Allow the screws a half spare turn, and

secure there with the nut(See NOTE on

page 8).

■ GEAR CASE

•At every 25 hours of use, supply grease to

the gear case. Pump in grease via the

grease fitting until it comes out of the root

of blades.

■ AIR FILTER

•The air filter, if clogged, will reduce the

engine performance. Monthly 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.

NOTE

WARNING

■ FUEL FILTER

•When the engine runs short of fuel supply,

check the fuel cap and the fuel filter for

blockage.

■ SPARK PLUG

•Starting failure and mis-firing are often

caused by a fouled spark plug. Periodically

clean the spark plug and check that the

spark gap is in the correct range. For a

replacement plug, use the correct type

specified by RedMax(See SPECIFI-

CATIONS on the page 15).

•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

overheated, and that this in turn could

cause the hedge-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 hedge-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

hedge-trimmer.

IMPORTANT

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 hedge-trimmer 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. 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.

■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 hedge-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 hedge-

trimmer. Note that failing to do so could

cause the muffler to become
