Thank you for choosing a MAKITA product!
We trust that you will be a satisfied customer. By choosing a MAKITA you have chosen one of the most advanced brushcutters.
The DBC 3310, DBC4010 and DBC4510 brushcutters
combine the benefits of state-of-the-art technology with
ergonomic design, and are professional machines intended for all types of use.
The high-efficiency engine is the heart of the brushcutter,
and has been completely redesigned. Special cylinder
geometry, computerized control times, and
maintenance-free electronic ignition give high performance with low fuel consumption.
The drive shaft is designed for continuous heavy-duty
use, with 9 bearings and a tough centrifugal clutch. The
fuel tank is positioned forward, for the right c to make long
jobs easier and less fatiguing.
Some of the other technical features of your MAKITA
brushcutter are:
- Precision-tuned vibration damping
Four conical hollow absorption elements, between
the engine and the main tube and between the engine
and the tank unit with handles, reduce felt vibration to
a minimum, for comfortable, untiring long-term working.
- Multi-function handle
All important controls are located on the right handle
for ease of operation.
- Easy cutting-tool change
A new locking system developed by MAKITA allows
you to lock the cutting tool for simple, safe blade
changing.
- High-efficiency noise reduction
The completely encapsulated engine and the
resonator-chamber intake muffler make this brushcutter remarkably quiet.
The following industrial property rights apply: US 512606,
EP 0438611, EP 0696414, GBM 9106194, GBM
9412925.
To ensure your own safety and to get the maximum
performance out of your MAKITA brushcutter, we urge

General precautions
To ensure correct operation, the user has to read this
instruction manual to make himself familiar with the
handling of the brushcutter. Insufficiently informed
users will risk danger to themselves as well as others
due to improper handling (1).
- It is recommended only to lend the brushcutter to
people who have experience with brushcutters. When
lending the brushcutter to someone else, give him this
Instruction Manual as well.
- First-time users should ask their dealer for basic
instructions, or contact a forestry school. To familiarize yourself with the basic handling of
gasoline-powered brushcutting, start out with trimming jobs before moving up to sawing.
- Children and persons under 18 years must not be
allowed to operate the brushcutter with metal cutting
tools (such as saw blades, steel bush cutter, star
blades etc.). Exceptions may be made for persons
over 16 for training purposes under the supervision of
a qualified trainer.
- Always use brushcutters with the utmost care and
attention.
- Operate the brushcutter only if you are in good physical condition. Perform all work calmly and carefully.
The user must accept liability for others.
- Never use the brushcutter after consumption of alcohol, drugs or medication (2).
Personal protective equipment
- The clothing worn should be functional and appropriate, i.e. it should be tight-fitting but not cause hindrance. Do not wear either jewellery or clothing which
could become entangled with bushes or shrubs.
- In order to avoid head-, eye-, hand- or foot injuries
as well as to protect your hearing, the following
protective equipment and protective clothing must
be used during operation of the brushcutter:
- It is recommended to wear a protective helmet; it is
imperative when working in forests. The protective
helmet (1) should be checked at regular intervals for
damage and must be replaced after 5 years at the
latest. Use only approved protective helmets. If you
have long hair, always wear a hairnet!
- The face shield (2) of the protective helmut protects
against flying sawdust, wood chips or stone chippings. During operation of the brushcutter always
wear goggles or a visor to prevent eye injuries.
- Wear adequate noise protection equipment to avoid
hearing impairement ( ear muffs (3), ear plugs etc.).
Octave brand analysis upon request.
- The forestry safety jacket (4) is equipped with spe-
cial red coloured shoulder parts. The arms and neck
should always be protected by clothing.
- The protective trousers (5) are made from a nylon
fabric with 22 layers and protects against cuts. We
strongly recommend its use. In any case, it is essential that a long pair of trousers made of tough material
be worn during operation of the brushcutter. Do not
wear short pants.
- Protective gloves (6) made of thick leather are part
of the prescribed equipment and must always be worn
during operation of the brushcutter.
- Safety shoes or boots (7) fitted with anti-skid sole,
steel toe caps and leg protection must always be
used. Safety shoes equipped with a protective layer
give protection against cuts and ensure a secure
footing. Do not wear sandals or go barefoot.

Handling fuels / Refuelling
- Stop the engine before refuelling.
- Keep away from open flame or sparks and do not smoke
while refuelling or mixing fuel (5).
- Let the engine cool down before refuelling.
- Fuel may contain substances similar to solvents. Eyes
and skin should not come in contact with mineral oil
products. Always wear protective gloves when refuelling
(5). Frequently clean and change protective clothes. Do
not breathe in fuel vapors. Inhalation of fuel vapours can
be hazardous to your health.
- Before refuelling the brushcutter make sure it is in a
stabile position.
- Do not spill fuel or oil. When you have spilt fuel or oil
immediately clean the brushcutter. Fuel should not
come in contact with clothes. If your clothes come in
contact with fuel, change them at once.
- Ensure that no fuel ooze into the soil (environmental
protection). Use an appropriate base.
- Refuelling is not allowed in closed rooms. Fuel vapors
will accumulate near the floor (explosion hazard).
- Carefully tighten the locking screw of the fuel tank and
inspect the fuel cap at regular intervals.
- Change the place before starting the engine at least 10
feet (3 meters) from the place of refuelling (6).
- Fuel cannot be stored for an unlimited period of time.
Buy only as much as will be consumed in the near future.
- Use only approved and marked containers for the transport and storage of fuel. Ensure children have no access
to fuel.

Putting into operation
- Do not work alone. Another person must be nearby
in case of emergencies (within shouting distance).
- Children and other persons must remain more than 50
feet (15 meters) from the working area. Keep an eye out
for animals as well (7).
- Before use always check that the brushcutter is safe
for operation:
Make sure the cutting tool is securely installed. The
throttle must automatically return to the off position
when released, and the throttle lever lock must work
properly. The cutting tool must not turn during idling. The
handles should be clean and dry. The on/off switch must
function properly. The guard must be undamaged and
securely installed in the correct position. Otherwise
you are in danger of injury!
- Start the brushcutter only in accordance with the instructions. Do not use any other methods for starting the
engine (8)!
- Use this brushcutter and its cutting tools only for the
uses they are intended for as specified in the documentation.
- Never use, for example, wire or wire-rope which can
break off and become a dangerous projectile. Use only
flexible, non-metallic line recommended in this manual.
- Start the brushcutter only after complete assembly
and inspection. Operation of the device is only
permitted after all the appropriate accessories are
attached!
- The cutting tool must be equipped with its appropriate guard. Never run the cutter without this guard!
- The cutting tool must not turn during idling. If necessary
adjust the idling speed.

- Before starting, make sure that the cutting tool has no
contact with hard objects such as branches, stones etc.
- The engine must be switched off immediately if there are
any noticeable changes in the behaviour of the equipment.
- Should the cutting tool hit stones or other hard objects,
immediately switch off the engine and inspect the cutting tool.
- Inspect the cutting tool at freqvent intervals for damage
(detect hairline cracks by means of tapping - noise test).
Hairline cracks can occur in the region of the base of the
teeth (9) after long use. Damaged cutting tools and
cutting tools with hairline cracks must not be used
any longer under any circumstances.
- Operate the brushcutter only with the shoulder strap
attached, which is to be suitably adjusted before putting
the brushcutter into operation (10). It is essential to
adjust the shoulder strap according to the user’s size to
prevent fatigue during use. Never hold the cutter with
one hand during use.
- When working with the brushcutter always hold it with
both hands (10). Keep cutting attachment below waist
level. Keep proper footing and balance at all times.
- Operate the brushcutter in such a manner as to avoid
inhalation of the exhaust gases. Do not start or operate
the brushcutter in closed rooms (risk of gas poisoning).
Carbon monoxide is an odorless gas; breathing exhaust
fumes can kill. Work only in well-ventilated places.
- When taking a break or leaving the brushcutter unattended, turn off the engine (11), make sure the cutting
attachment has stopped and set the brushcutter down in
such a way that there is no risk of injury to yourself or
others.
- Never put the hot brushcutter onto dry grass or onto any
combustible materials.
- Shut off the engine during transport or when moving on
to a new location (11).
- Never operate the engine with a faulty exhaust muffler.
If the spark arrestor screen is damaged, replace it
immediately. The use of the brushcutter with a damaged
spark arrestor can cause bushfires!

Kickback (Blade Thrust)
When operating the brushcutter, uncontrolled kickback
may occur.
This particularly the case when cutting in the area between
12 and 2 (12).
Never start a cut in this area when cutting hard objects such as brush, bushes etc.
If you do this, the brushcutter will be thrown to one side at
high speed and with great force. High risk of injury!
Never start a cut in the area between 12 and 2 (Fig. 12).
Kickback prevention (13):
- To avoid kickbacks, observe the following:
- Always watch what you´re doing! Be careful when
continuing cuts started previously.
- The cutting tool must be turning at full speed before
starting cuts.
- There is a high risk of injury in the area between 12 and
2, especially when using metal cutting blades.
- Cuts in the areas between 11 and 12 and between 2
and 5 should be performed only by trained operators
and at their own risk.
- Easy, low-kickback cutting is possible in the area between 8 and 11.

Working behavior / Method of working
- Use the brushcutter only in good light and visibility.
During the winter season beware of slippery or wet
areas, ice and snow (risk of slipping). Always ensure a
safe footing.
- Never cut above your shoulder height.
- Never stand on a ladder and run the brushcutter.
- Never climb up into trees to perform cutting operations
with the brushcutter.
- Never work on unstable surfaces.
- Make sure the cutting area is free of foreign objects such
as stones and metal items. Foreign particles can rebound (danger of injury, 14), damage the cutting tool
and cause dangerous kickbacks.
- Before commencing cutting, the cutting tool must have
reached full working speed.
Applications for cutting tools
Employ only the correct cutting tool for the job in hand (15)!
Do not use tools for jobs they are not designed for.
2-line -/ 4-line trimmer head:

Maintenance
- Always make sure the brushcutter is in good working
order before using it. This includes in particular the
cutting tool, guard, harness and fuel system (check for
leaks). Particular attention must be paid to the cutting
blades, which must be correctly sharpened.
CAUTION: Metal cutting tools must be sharpened only
at an authorized service centre!
A tool which has been improperly sharpened can cause
unbalance and thus considerable danger of injury.
Apart from this, the equipment may be damaged due to
vibrations.
- When changing the cutting tool, cleaning the brushcutter
and the cutting tool etc., it is essential to switch off the
engine and pull the spark plug cap.
- Replace cracked, bent, warped, damaged or dull cutting
tools immediately. Never straighten or weld damaged
cutting tools.

as possible. In particular check the correct setting of the
carburetor.
- Clean the brushcutter at regular intervals and check that
all screws and nuts are well tightened.
- Never service or store the brushcutter near open flames
(18)!
- Always store the brushcutter in a locked storage area,
with the fuel tank completely empty and the carburetor
run dry. Keep the brushcutter out of reach of children.
Observe the accident pre- vention instructions issued
by the relevant trade associations and insurance companies. Do not make any modifications to the brushcutter - you will only be putting your own safety at risk!
The performance of maintenance or repair work by the user
is limited to those activities described in this instruction
manual. All other work must be done by the MAKITA
customer service (19).
Use only original MAKITA spares and accessories.
The use of non-MAKITA spares, accessories, or cutting

Fuel mixture
Gasoline
1.0 Us-gal. (3.7 l)
2.5 Us-gal. (9.4 l)
5.0 Us-gal. (18.9 l)
The brushcutter is powered by a high-performance two-stroke
engine. The engine runs on a mixture of gasoline and two-stroke
engine oil.
The engine was designed for regular lead-free gasoline with an
octane number of at least 91 ROZ. If this is not available,
higher-octane gasoline may be used. This will not damage the
engine, but may impair engine performance.
A similar situation will arise from the use of leaded fuel. To
obtain optimum engine operation and to protect your
health and the environment, only unleaded fuel should be
used! Gasoline which contens alcohol should not used in
MAKITA products.
For lubricating the engine use a two-stroke engine oil (quality
grade: API-TC), which is added to the fuel. The engine has
been designed for use of MAKITA HP 100 high-performance
two-stroke engine oil and a mixture ratio of only 100:1 to protect
the environment. In addition, a long service life and reliable
operation with a minimum emission of exhaust gases are
ensured.
MAKITA HP 100 high-performance two-stroke engine oil is
available in the following sizes:
0.5 l part no. 980 008 609
MAKITA high-performance two-stroke engine oil is available in
two different sizes:
1 l part no. 980 008 607
100 ml part no. 980 008 606
In case MAKITA high-performance two-stroke engine oil is not
available, it is urgently recommended to use a mixture ratio of
40:1 with other two-stroke engine oils, as otherwise optimum
operation of the engine cannot be guaranteed.
Preparation of the correct mixture ratio:
50:1 When using MAKITA high-performance two-stroke oil,
i.e. 50 parts gasoline /1 part oil.
100:1 when using MAKITA HP 100 high-performance two-
stroke engine oil, i. e. mix 100 parts gasoline with 1 part
oil.
40:1 When using other brands, i.e. 40 parts gasoline / 1 part
oil.
Note:
When preparing the fuel mixture, always first mix the entire oil
quantity with half of the gasoline, and then add the rest of the
gasoline. Shake the mixture well before putting in the fuel tank.
It is not wise to add more oil to the mixture than specified, even
if this may seem safer for the engine. More oil only leads to
increased combustion residues, which not only pollute the
environment, but are also bad for the cylinder exhaust
channel, muffler and the spark arrester screen. Furthermore
fuel consumption will increase and performance will fall.

AVOID SKIN AND EYE CONTACT!
Utmost care is required when handling fuel. Fuel may contain
substances similar to solvents. Refuel either in a well ventilated
room or outdoors. Do not inhale fuel vapours. Fuel vapours are
poisonous and can be hazardous to your health. Avoid eye and
skin contact with fuels and mineral oils. Mineral oil products
degrease your skin. If your skin comes in contact with these
substances repeatedly and for an extended period of time, it will
desiccate. Various skin deseases may result. In addition, allergic reactions are known to occur. Eyes can be irritated by
contact with oil. If oil comes into your eyes, immediately wash
them with clear water.
If your eyes are still irritated, see a doctor immediately!
Storage of Fuel
Fuels have a limited storage life. Fuel and fuel mixtures age.
Therefore fuel and fuel mixtures, which have been stored for
too long, can cause starting problems. Purchase only that
amount of fuel, which will be consumed over the next few
months.
Store fuel safely in a dry place in approved containers
only.

Carburetor adjustment
Important information:
The carburetor of this tool is fitted with limiter caps which restrict
the range of adjustment and prevents over-rich mixture
settings. This ensures providing good engine power and
efficient fuel consumption.
Before installing the limiter caps, the manufacturer performs
the „Basic Adjustment” procedure.
Maximum power is achieved throughcarburetor adjustment. It requires a warm engine and a clean air filter and
should preferably be performed by an expert.
The carburetor comes factory-set for the atmospheric pressure at sea-level. At other elevations and during the run-in
phase with a new engine it may be necessary to adjust the
carburetor.
A tachometer (order no. 950 233 210) is a must for accurate
carburetor adjustment.
Before adjusting the carburetor, install the cutting tool you are
going to use and warm up the engine by running it 3-5 minutes.

Set idling speed (step 3)
- If the cutting tool turns when the engine is idling, screw the
throttle-valve stop screw (S) until the cutting tool stops
turning. The idling speed should be now 2,300-2,500 rpm/
min.
For a precise adjustment the following steps are to be
performed:
1. Check adjustment
2. Start engine
3. Set idling speed
4. Adjust speed
5. Check idling speed
6. Check acceleration
7. Check max. speed or output

Adjustment instructions (step 1)
- Before initial operation make sure that the adjusting screws
(H and L) have not been set in all the way. Limiter caps do
not protect the engine from leaning.
- Turn the two adjusting screws (H and L) counter-clockwise as far as they will go.
- Start the engine and let it warm up (step 2).
STOP
Adjust speed (step 4)
- Set the engine speed to 13,000-13,500 RPM by adjusting
the main jet screw (H). Screwing it in makes the fuel/air
mixture leaner (less fuel, more air) and increases the engine
speed.
Caution:
Engine speeds above 13,500 RPM reduce engine life!
L
C
Check idling speed (step 5)
- Now check the idle speed. It should be 2,300-2,500 RPM
(the cutting tool should not turn). If necessary, adjust the
idle speed with the idle jet screw (L). Turning it in increases
the speed, and turning it out decreases it.
Check acceleration (step 6)
- This is the time it takes for the engine to go from idle speed
to maximum speed when you press the throttle hard.
- If acceleration is too slow, turn the idle screw (L) out about
1/8 turn.

Instructions for maintenance
Do not do any maintenance or servicing work not described in this Instruction Manual. All such work may be done only by a MAKITA
service station.
After refuelling the brushcutter 50 times, it should be given a thorough maintenance check and a complete inspection at a MAKITA
service centre.
Daily maintenance
Perfom the following work daily after use:
- Clean the outside of the brushcutter and inspect for damage.
- Clean the air filter (see below). Under dusty working conditions the air filter must be cleaned more often.
- Check the cutting tool for damage and make sure it is tight.
- Check to make sure that there is sufficient difference between the idle and engagement speed so that the cutting tool does not
turn when the engine is idling. If necessary, reduce the idle speed (see page 17). If the cutting tool still turns during idling, take
the brushcutter to a service center.
- Check the function of the safetylocking button, the short-circuiting switch and of the throttle lever (see page 16).
Cleaning the air filter
- Remove the air filter cover (I/15). Close the choke lever
(I/16) to prevent the entry of dust particles into the
carburetor.
- Remove the air filter (I/17) and clean it with a soft brush.
Caution:
To prevent eye injuries, do not blow out dirt particles.
- Very dirty filters can be cleaned out using regular
dishwashing liquid in lukewarm water.
- In case of strong pollution clean more often (several times
a day) because only a clean filter ensures full engine power.
