[1] SAFETY PRECAUTIONS
□In order to ensure proper and safe operation of your trimmer
・Read this pole hedge trimmer operating 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.
・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 possibility exists that your judgment might
be impaired or that you might not be able to operate the 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 trimmer.
・Avoid running the engine indoors.
・The exhaust gases contain harmful carbon monoxide.
・Never use your 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 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 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 trimmer to a wide,
clear, open space, turn on the power, and practice handling the 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 trimmer is to be
used continuously to somewhere around 30~40 minutes per session, and take 10~20minutes of rest
between work sessions. Also try to keep the total amount of work performed in a single day under 2
hours of less.
□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 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 MARUNAKA 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 source of heat of fire which might ignite the fuel.
・Smoking while operating the trimmer or refilling its fuel tank is extremely dangerous. Always be sure to
keep lit cigarettes away from the 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 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.
□Things to check before using your trimmer
・Before beginning work, look around carefully to get a feel for the shape of land, the trees, hedges, or
bushes to be trimmed, and whether or not there are 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, warnings signs, or some other from 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.
・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 objects exist within a perimeter of 15 feet or less
around the trimmer before starting the engine.
・The 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 MARUNAKA servicing
dealer for repair.
□Avoid noise problem
・Check and follow the local regulations as to sound level and hours of operations for trimmer.
・In general, operate trimmers between 8a.m.and 5p.m.on week days and 9a.m.to 5.p.m.weekends.
Avoid using trimmer late at night and/or early in the morning.
□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.
2

・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 branch, always be sure to wear the required safety
equipment, and be careful when working to match 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 wise 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 the fuel from the fuel tank, as during 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 MARUNAKA 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 MARUNAKA products or products which have been certified by MARUNAKA for use with
the MARUNAKA trimmer.

drop.
(2) Remove obstructions around the hedge. Determine a safe refugee.
(3) In the trimming work, rotate the engine at high speed.
(4) When trimming a long twig or deeply trimming the hedge, trim it in several times.
(5) When cutting a branch, lightly press the pole hedge trimmer against the branch. Just before cutting
it off, release the force and hold the pole hedge trimmer.
[9] PRECAUTIONS DURING WORKING
1. If the blades have stopped on account of a branch caught during the trimming, first be sure to stop
the engine and eliminate the blanch. Refrain from cutting too hard or too thick a branch (over 7 mm in
diameter).
2. When the machine is running, never touch the blade. Never direct the blades to person.
3. Absolutely avoid handing the machine with a single hand because it might cause jerking, drop of the
hedge trimmer, and so on.
4. The engine speed must not be excessive but just enough to cut the damage. Run the hedge trimmer
at a rated speed (5500-8000 rpm) whenever possible.
5. To avoid a bum, do not touch the engine during the operation or immediately after stopping the
engine. Handle the engine after it is completely cooled.
6. During the operation, the stance must be firm. And, do not work in an unstable condition.
Refrain from working in an unnatural posture or by a risky method.
7. Do not use the pole hedge trimmer continuously for a long time. It is normal to take a break of 10 to
20 minutes after every 50-minute operation.
8. In every 50 hours, inject a proper amount of grease in the crank case of the hedge trimmer.
9. Stop the engine before lubricating the blades during the operation.
10. Stop the engine before leaving the pole hedge trimmer.
[10] MAINTENANCE, INSPECTION AND SERVICING
For repair, make sure to use specified genuine parts.
1. Gear case
NOTE
Though the gear case is equipped with the grease outflow prevention
mechanism, the grease may flow out a little from the blade sliding area.
It does not mean failure.
(1) At every 50 operating hours, supply grease.
(2) Inject grease from the grease injection port in the gear case.
2. Adjusting the blade
The blade is attached to the blade guide with four bolts.
These bolts are tightened while securing proper clearance so that
the blade can move smoothly.
If the clearance is too narrow, the blade does not move smoothly,
and the sliding area may be seized.
If the clearance is too wide, the blade does not cut well.
8

3. Adjust the clearance of the blade using the following procedure.
(1) Loosen the blade coupling nuts.
(2) Completely tighten the blade coupling bolts, and then loosen them by
a half turn.
(3) With each bolt fixed in the position in which it is loosened by
a half turn from the completely tightened position, tighten the blade
coupling nuts.
NOTE
Supply a proper amount of machine oil to the blade sliding area.
[11] STORAGE AFTER OPERATION
1. Clean every part, repair sections, and apply a thin coat of oil on metallic
parts to prevent rust.
2. If the pole hedge trimmer is to be stored for long periods, drain the fuel
from the tank then start the engine and keep the engine running until it
stops to consume all the fuel left in the carburetor.
3. Store the pole hedge trimmer in a place free from excessive humidity
so as to prevent the dust from soiling the machine.
4. Remove the spark plug; inject a small amount of engine oil through the spark plug hole.
Then pull the recoil starter a few times to put a thin coat of oil on the cylinder.
