– During operation, always hold the Brush Cutter/String Trimmer with both
hands.
Always ensure you are on safe footing.
– Operate the Brush Cutter/String Trimmer in such a manner as to avoid
inhalation of the exhaust gases. Never run the engine in an enclosed space
such as inside a room (risk of gas poisoning). Carbon monoxide is an odorless
gas.
– Always switch off the engine when resting, or if you intend to leave the Brush
Cutter/String Trimmer unattended, and place it in a safe location to prevent
injury to other people and damage to the equipment.
– Never put the hot Brush Cutter/String Trimmer onto dry grass or onto any
other combustible materials.
– The cutting tool must always be equipped with the appropriate guard.
Never run the cutter without this guard!
– All protective installations and guards supplied with the equipment must be
used during operation.
– Never operate the engine if the exhaust muffler is faulty.
– Shut off the engine during transport.
– When transporting the equipment, always attach the cover to the cutting
blade.
– Ensure the Brush Cutter/String Trimmer is positioned safely during transport
to avoid fuel leakage.
– When transporting the Brush Cutter/String Trimmer, ensure the fuel tank is
completely empty.
– When unloading the Brush Cutter/String Trimmer from a truck or other such
vehicle, never drop the engine to the ground, as doing so may severely
damage the fuel tank.
– Unless in an emergency, never drop or cast the Brush Cutter/String Trimmer
to the ground as doing so may severely damage the Brush Cutter/String
Trimmer.
– Always lift the entire equipment from the ground when moving it. Dragging the
equipment on its fuel tank is extremely dangerous and may cause fuel to leak,
which may cause fire.
– If the equipment gets heavy impact or fall, check the condition before
continuing work. Check the fuel system for fuel leakage and the controls and
safety devices for malfunction. If there is any damage or doubt, ask our
authorized service center for the inspection and repair.
Refuelling
– Shut off the engine during refuelling, keep away from open flames and do not
smoke during refuelling.
– Ensure mineral oil products do not come into contact with skin. Do not inhale
the fuel vapor. Always wear protective gloves during refuelling. Change and
clean protective clothing at regular intervals.
– To prevent soil contamination (environmental protection), make sure you do
not spill fuel or oil on the ground. If you do spill fuel, clean the Brush Cutter/
String Trimmer immediately.
– Make sure fuel does not come into contact with your clothing. If fuel does
come into contact with your clothing, change your clothing immediately to
prevent fire.
– Inspect the fuel cap at regular intervals to make sure that it can be securely
fastened and does not leak.
– Carefully tighten the fuel tank cap. Once refuelling is complete, move to a
location at least 3 meters away from where you refuelled before starting the

– Never refuel in an enclosed space such as inside a room. Doing so may cause
an explosion due to the accumulation of fuel vapor at ground level.
– Only transport and store fuel in approved containers. Make sure stored fuel is
not accessible to children.
Method of operation
– Only use the Brush Cutter/String Trimmer in good light and visibility. During
the winter season, beware of slippery or wet areas such as icy or snow-
covered areas (risk of slipping). Always ensure you are on safe footing.
– Never cut above waist height.
– Never stand on a ladder while using the Brush Cutter/String Trimmer.
– Never climb up into trees to use with the Brush Cutter/String Trimmer.
– Never work on unstable surfaces.
– Remove sand, stones, nails etc. found within the working range.
Foreign objects may damage the cutting tool and can cause dangerous kick-
backs.
– Before starting to cut, make sure the cutting tool has reached full working
speed.
– If grass or branches get caught between the cutting tool and guard, always
stop the engine before cleaning. Otherwise unintentional blade rotation may
cause serious injury.
– Take a rest to prevent loss of control caused by fatigue. We recommend to
take a 10 to 20-minute rest every hour.
Kickback (blade thrust)
– When operating the brush cutter, uncontrolled kickbacks may occur.
– Kickbacks occur frequently when attempting to cut with the 12 to 2 o’clock
section of the blade.
– Never apply the 12 to 2 o’clock section of the brush cutter blade.
– Never apply this section of the brush cutter blade to solid objects, such as
bushes or trees etc. that have a diameter greater than 3cm. Doing so will
cause the brush cutter to deflect with a large amount of force, which is
extremely dangerous and may cause injury.
Kickback prevention
To avoid kickbacks, remember the following:
– Using the 12 to 2 o’clock section of the blade is extremely hazardous,
especially when using metal cutting tools.
– Cutting operations using the 11 to 12 o’clock section and 2 to 5 o’clock section
of the blade must only be performed by trained and experienced operators,
and then only at their own risk.
The optimum cutting section for easy cutting with almost no kickback is
between the 8 to 11 o’clock section of the blade.
Cutting Tools
Ensure you use the correct cutting tool for each particular job.
DBC260U with cutter blade (Star Blade (4 teeth), Eddy Blade (8 teeth)),
DBC260L with Nylon cutting head.
Never use other blades including metal multi-piece pivoting chains and flail
blades. Otherwise serious injury may result.
For cutting thick materials such as weed, high grass, bushes, shrubs,
underwood, thicket etc. (max. 2 cm dia. thickness). Perform this cutting work by
swinging the brush cutter evenly in half-circles from right to left (in a similar way
to using a scythe).
Maintenance instructions
– Have your equipment serviced by our authorized service center, always using
only genuine replacement parts. Incorrect repair and poor maintenance can
shorten the life of the equipment and increase the risk of accidents.
– Always check the condition of the cutter, in particular the cutter protective
devices and shoulder strap, before commencing work. Particular attention
should also be paid to the cutting blades, which must be correctly sharpened.
– Turn off the engine and remove the spark plug connector when replacing or
sharpening cutting tools, and also when cleaning the cutter or cutting tool.

Handling fuel
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
vapors, and avoid any contact of fuel or oil with your skin.
Mineral oil products degrease your skin. Prolonged skin contact with these
products will cause your skin to become extremely dry, which may result in
various kinds of skin disease. In addition, allergic reactions may 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.
Fuel and oil mixture
The brush cutter engine is a high-efficiency two-stroke engine. It runs on a
mixture of fuel and two-stroke engine oil. The engine is designed for unleaded
regular fuel with a min. octane value of 91 RON. If for any reason no such fuel is
available, you can use fuel with a higher octane value. This will not affect the
engine, but it may cause poor operating behaviour.
Similar problems will arise from the use of leaded fuel. To obtain optimum engine
operation and to protect your health and the environment, use only unleaded
fuel!
To lubricate the engine, add two-stroke engine oil (quality grade: JASO FC or
ISO EGD) to the fuel. The engine has been designed to use the specified two-
stroke engine oil at mixture ratio of 50:1 to protect the environment.
Additionally, long service life accompanied by reliable operation and minimum
emissions are guaranteed through the use of this mixture ratio. Reliable
functioning of the brush cutter cannot be guaranteed unless this mixture ratio of
50:1 (specified 2-stroke engine oil) is strictly observed.
Correct mixture ratio:
Gasoline: Specified two-stroke engine oil = 50 : 1 or
Gasoline: Other manufacturer’s two-stroke engine oil = 25 : 1 recommended
NOTE: To prepare the fuel-oil mixture, first mix the entire oil quantity with half of
the fuel required, then add the remaining fuel. Thoroughly shake the
mixture before pouring it into the brush cutter tank. To ensure safe
operation, do not add more engine oil than the specified amount. Doing
so will only result in a higher production of combustion residues which
pollute the environment and clog the exhaust channel in the cylinder as
well as the muffler. In addition, the fuel consumption will rise and the
performance will decrease.
Refuelling
The engine must be switched off.
– Thoroughly clean the area around the fuel filler cap (2) to prevent dirt from
getting into the fuel tank (1).
– Unscrew the fuel filler cap (2) and fill the tank with fuel.
– Tightly screw on the fuel filler cap (2).
– Clean the screw fuel filler cap (2) and tank after refueling.
Storage of Fuel
Fuel cannot be stored for an unlimited period of time.
Purchase only the quantity required for a 4-week operating period. Only use
approved fuel storage containers.

section of the spark plug.
Caution during operation:
If the throttle lever is opened fully during a no-load operation, the engine revolutions increase over 10,000 min-1. Never operate the engine at a
higher speed than required, and keep the revolutions at an approximate speed of 6,000 - 8,000 min-1.
CAUTION: Always reduce the engine revolutions when the equipment is not being used for work.
Operating the equipment at high revolutions when not being used for work will shorten the lifespan of the equipment.
Warm start
– Follow the instructions for cold start above, except without moving the choke lever (choke lever remains in the down position ()).
Stopping
– Release the throttle lever (3) fully, and when the engine rpm has lowered,
push the I-O switch (1) to “O” position to stop the engine.
– Be aware that the cutting head may not stop immediately, and always allow it
to slow down and stop fully by itself.

ADJUSTMENT OF LOW-SPEED REVOLUTIONS (IDLING)
The cutter blade or the nylon cutting head should not rotate when the control
lever is fully released. If necessary, adjust the idling rpm using the idling
adjustment screw.
Checking the Idling speed
– The idling speed should be set to 3,000 min-1.
If necessary, adjust the idling speed using the idling screw (the blade or the
nylon cutting head must not turn when the engine is idling).
Tightening the idling screw (1) increases the engine revolutions, whereas
loosening the idling screw reduces the engine revolutions.
CAUTION: The cutting tools listed below must only be resharpened by an
authorized facility. Manual resharpening will result in imbalances of
the cutting tool, which will cause vibrations and damage to the
equipment.
– cutter blade (star blade (4 teeth), eddy blade (8 teeth))
A professional resharpening and balancing service is provided by Authorized
Service Agents.
NOTE: To increase the service life of the cutter blade (star blade, eddy blade)
the blade may be turned over to allow both cutting edges to wear.
NYLON CUTTING HEAD
The nylon cutting head is a dual string trimmer head capable of both automatic
and bump & feed mechanisms.
The nylon cutting head will automatically feed out the proper length of nylon cord
by the changes in centrifugal force caused by increasing or decreasing rpms.
However, to cut soft grass more efficiently, bump the nylon cutting head against
the ground to feed out extra cord as shown in operation section.
Operation
– Increase the nylon cutting head speed to approx. 6,000 min-1.
Nylon cord will not feed out correctly at lower speeds (under 4,800 min-1).
– The most effective cutting area is shown by the shaded area in the diagram to
the right.
If the nylon cord does not feed out automatically, follow the instructions below:
1. Release the throttle lever so that the engine idles, and then squeeze the
throttle lever fully. Repeat this procedure until the nylon cord feeds out to the
proper length.
2. If the nylon cord is too short to feed out automatically using the procedure
above, bump the knob of the nylon cutting head against the ground to feed
out the nylon cord.
3. If the nylon cord does not feed out using procedure 2, rewind/replace the
nylon cord by following the procedures described under “Replacing the nylon
cord”.
Replacing the nylon cord
– Stop the engine.
– Press the housing latches inward to lift off the cover, then remove the spool.

– Hook the center of new nylon cord into the notch in the center of the spool,
with one end of the cord extending about 80mm (3-1/8”) more than the other.
Then wind both ends firmly around the spool in the direction of the head
rotation (left-hand direction indicated by LH and right-hand direction by RH on
the side of the spool).
– Wind all but about 100mm (3-15/16”) of the cords around the spool, leaving
the ends temporarily hooked through the notch on the side of the spool.
– Mount the spool in the housing so that the grooves and protrusions on the
spool match up with those in the housing. Mount the spool so that the writing
on the spool is visible from above. Next, unhook the ends of the cords from
their temporary position, and feed the cords through the eyelets so that they
protrude from the housing.
– Align the protrusion on the underside of the cover with the slots of the eyelets.
Then push cover firmly onto the housing to secure it.
Servicing instructions
CAUTION: Before performing any type of maintenance work on the Brush
cutter, always switch off the motor and detach the plug cap from the
spark plug (see “checking the spark plug”).
Always wear protective gloves.
CAUTION: Never remove the recoil starter yourself. Doing so may cause an
accident. This procedure should only be performed by an Authorized
Service Agent.
To ensure a long service life and to avoid any damage to the equipment, perform the following maintenance operations regularly.
Daily inspection and maintenance
– Before operation, check the equipment for loose screws or missing parts. Pay particular attention to the tightness of the cutter blade or nylon
cutting head.
– Before operation, always check to make sure that the cooling air passage and cylinder fins are not clogged.
Clean them if necessary.
– Perform the following maintenance operations daily after use:
• Clean the Brush cutter externally and inspect it for damage.
• Clean the air filter. When working under extremely dusty conditions, clean the filter several times a day.
• Check the blade or the nylon cutting head for damage and make sure it is firmly mounted.
• Check that there is sufficient difference between the idling and operating speeds to ensure the cutting tool is at a standstill while the engine
is idling (if necessary, reduce the idling speed).
If the cutting tool continues to rotate during engine idling, consult your nearest Authorized Service Agent.
– Check that the I-O switch, the lock-off lever, the control lever, and the lock button are all functioning correctly.

Cleaning the air cleaner (filter)
– Unscrew screw (1).
– Turn the choke lever (4) to the fully closed side, and keep the carburetor away
from any dust or dirt.
– Remove the air cleaner cover (3).
– Remove the sponge element (2), wash it in lukewarm water and dry it
completely.
– After cleaning, put back the air cleaner cover (3) and fasten it with screw (1).
NOTE: If there is excessive dust or dirt adhering to the air cleaner, clean it every
day. A clogged air cleaner may make it difficult or impossible to start the
engine, or may increase the engine rotational speed.
Checking the spark plug
– Only use the supplied universal wrench to remove or to install the spark plug.
– The gap between the two electrodes of the spark plug should be 0.6-0.7mm
(0.024”-0.028”). If the gap is too wide or too narrow, adjust it. If the spark plug
is clogged with carton or dirty, clean it thoroughly or replace it.
CAUTION: Never touch the spark plug connector while the engine is running
(danger of high voltage electric shock).
Supply of grease to gear case
– Supply grease (Shell Alvania 3 or equivalent) to the gear case through the
grease hole every 30 hours. (Genuine MAKITA grease may be purchased
from your MAKITA dealer.)
Suction head in the fuel tank
– The fuel filler (5) of the suction head is used to supply the fuel required by the
carburetor.
– Visually inspect the fuel filter periodically. To inspect the filter, open the tank
cap, use a wire hook and pull out the suction head through the tank opening.
Replace the filter if it has hardened, become particularly dirty, or clogged.
– Insufficient fuel supply may result in the maximum permissible speed being
exceeded. Therefore, the fuel filter must be replaced at least quarterly to
ensure satisfactory fuel supply to the carburetor.
Any other maintenance or adjustment work that is not described in this manual must only be performed by Authorized Service Agents.
