Only start the brush cutter engine, after the entire assembly is done.
Operation of the device is only permitted after all the appropriate accessories
are attached.
Before starting make sure that the cutting tool has no contact with hard
objects such as branches, stones etc. as the cutting tool will revolve when
starting.
The engine is to be switched off immediately in case of any engine problems.
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 short regular intervals for damage (detection of
hairline cracks by means of tapping-noise test).
Operate the brush cutter only with the shoulder strap attached which is to be
suitably adjusted before putting the brush cutter into operation. It is
essential to adjust the shoulder strap according to the users size to prevent
fatigue occurring during use. Never hold the cutter with one hand during
use.
During operation always hold the brush cutter with both hands.
Always ensure a safe footing.
Operate the brush cutter in such a manner as to avoid inhalation of exhaust
gas. Never run the engine in enclosed rooms (risk of gas poisoning).
Carbon monoxide is an odorless gas.
Switch off the engine when resting and when leaving the brush cutter
unattended, and place it in a safe location to prevent danger to others or
damage to the machine.
Never put the hot brush cutter onto dry grass or onto any combustible
materials.
The cutting tool has to be equipped with its appropriate guard.
Never run the cutter without this guard.
All protective installations and guards supplied with the machine must be
used during operation.
Never operate the engine with faulty exhaust muffler.
Shut off the engine during transport.
During transport over long distances the tool protection included with the
equipment must always be used.
Ensure safe position of the brush cutter during car transportation to avoid
fuel leakage.
When transporting the brush cutter, ensure that the fuel tank is completely
empty.
When unloading the Brush Cutter from the truck, never drop the Engine to
the ground or this may severely damage the fuel tank.
Except in case of emergency, never drop or cast the Brush Cutter to the
ground or this may severely damage the Brush Cutter.
Remember to lift the entire equipment from the ground when moving the

Method of operation
Only use the brush cutter in good lighting and visibility. During the winter
season beware of slippery or wet areas, ice and snow (risk of slipping).
Always ensure a safe looting.
Never cut above the shoulder height.
Never stand on a ladder and run the brush cutter.
Never climb up trees to perform cutting operation with the brush cutter.
Never work on unstable surfaces.
Remove sand, stones, nails etc. found within the working range.
Foreign particles may damage the cutting tool and can cause dangerous
kick-backs.
Before commencing cutting, the cutting tool must have reached full working
speed.
Kickback
When operating the brush cutter, uncontrolled kickback may occur.
This is particularly the case when attempting to cut within a blade segment
between 12 and 2 oclock.
Never apply the brush cutter within a segment between 12 and 2 oclock.
Never apply this segment of the brush cutter blade to solids, such as bushes
and trees, etc., having a diameter in excess of 3 cm or the brush cutter will
be deflected at great force with the risk of injuries.
Kickback prevention
To avoid kickbacks, observe the following:
Operation within a blade segment between 12 and 2 oclock presents
positive hazards, especially when using metal cutting tools.
Cutting operations within a blade segment between 11 and 12 oclock, and
between 2 and 5 oclock, must only be performed by trained and experienced
operators, and then only at their own risk.
Easy cutting with almost no kickback is possible within a blade segment
between 8 and 11 oclock.
Cutting Tools
Employ only the correct cutting tool for the job in hand.
Nylon cutting head:
Exclusively designed for cutting along walls, fences, grass edges, trees, posts
etc. (supplementing the grass mower). Perform this cutting work by swinging
the grass trimmer evenly in half-circles from left to right.
Cutter blade (Star Blade (4 teeth), Eddy Blade (8 teeth), Brush Blade (3
teeth)):
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 (similar to
using a scythe).
Maintenance instructions
The condition of the cutter, in particular of the cutting tool of the protective
devices and also of the shoulder strap must be checked before commencing
work. Particular attention is to 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.

FUELS/REFUELING
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, avoid any contact of fuel or oil with your skin.
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 diseases may result. 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 engine of the brush cutter is a high-efficiency two-stroke engine. It is run
with 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. In case no such
fuel is available, you can use fuel with a higher octane value. This will not
affect the engine, but may cause poor operating behaviour.
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!
For lubricating the engine use a two-stroke engine oil (quality grade: TC-3),
which is added to the fuel. The engine has been designed for use with
specified two-stroke engine oil and a mixture ratio of only 25:1 to protect the
environment. In addition, a long service life and a reliable operation with a
minimum emission of exhaust gases is guaranteed. It is absolutely essential
to observe a mixture ratio of 25:1 (specified 2-stroke engine oil), as otherwise
reliable function of the brush cutter cannot be guaranteed.
The correct mixture ratio:
Mix 25 parts gasoline with 1 part specified 2-stroke engine oil (see table on
right).
NOTE: For preparing 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 filling it into the brush cutter tank. It is not wise to
add more engine oil than specified to ensure safe operation.
This will only result in a higher production of combustion residues which
will 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.
The engine must be switched off.
Thoroughly clean the area around the fuel filler cap, to prevent dirt from
getting into the fuel tank.
Unscrew the fuel filler cap and fill the tank with fuel.
Tightly screw on the fuel filler cap.
Clean screw fuel filler cap 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.

Do not pull out the starter rope to its full extent and do not allow the starter
handle to be retracted without control, but ensure that it is retracted slowly.
Repeat the starting operation until initial ignitions are heard.
Depress the choke lever ( ) and pull the starter rope again until the
engine starts.
As soon as the engine starts, immediately tap and release the throttle, thus
releasing the half-throttle lock so that the engine can run in idle.
Run the engine for approximately one minute at a moderate speed before
applying full throttle.
Caution during operation:
If the control lever is opened fully in a no-load operation, the engine rotation is increased to 10,000 min
-1
or more. Never operate the engine at
a higher speed than required and at an approximate speed of 6,000 - 8,000 min
-1
.
Starting the warm engine
Same as above, except without moving the choke lever (choke lever remains
in the down position).
Stopping
Release the control lever (3) fully, and when the engine rpm has lowered,
push the I-O switch (1) to O position the engine will now stop.
IDLE ADJUSTMENT
Never attempt to make engine adjustments while the unit is running and
strapped to the operator. Always make engine adjustments with the unit
resting on a flat, clear surface.
The cutter blade or the nylon cutting head should not run when the control lever
is fully released. If necessary, adjust the idle rpm using the idle adjusting
screw.
Checking the Idle speed
Idle speed should be set to 2,600 min
-1
.
If necessary correct it by means of the idle adjustment screw (the blade or
the nylon cutting head must not turn when the engine is on idle.)
Turning in the screw clockwise will cause an increase in the engine speed,
whereas turning the screw counterclockwise will reduce the engine speed.

RESHARPENING THE CUTTING TOOL
CAUTION: The cutting tools mentioned below must only be resharpened by an
authorized facility. Manual resharpening will result in imbalances
of the cutting tool causing vibrations and damage to the equipment.
cutter blade (star blade (4 teeth), eddy blade (8 teeth), brush blade(3 teeth))
An expert resharpening and balancing service is provided by Authorized
Service Agents.
NOTE: To increase the service life of the cutter blade (star blade, eddy blade)
it may be turned over once, until both cutting edges have become blunt.
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
indicated under operation section.
Operation
Increase the nylon cutting head speed to approx. 6,000 min
-1
.
Low speed (under 4,800 min
-1
) is not suitable, the nylon cord will not feed out
properly at low speed.
The most effective cutting area is shown by the shaded area.
If the nylon cord does not feed out automatically, proceed as follows:
1. Release the control lever to run the engine idle and then squeeze the control
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 with the above
procedure, 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 with procedure 2, rewind/replace the
nylon cord by following the procedures described under Replacing the nylon
cord.

If under idling conditions the tool should still continue to run, consult your
nearest Authorized Service Agent.
Check the functioning of the I-O switch, the lock-off lever, the control lever,
and the look button.
Cleaning of air cleaner
Raise the lock lever (1) of the air cleaner cover and release the lock.
Hold the right and left sides of the air cleaner cover, press it to the inside and
then remove it.
Push the choke lever (2) up (arrow), to prevent dirt particles from entering the
carburetor.
Remove the sponge element (3).
Wash it with lukewarm water and then dry it thoroughly.
After cleaning, put back the sponge element and install the air cleaner cover
(4) and tighten the screw to secure.
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 or run the engine at proper rotational speeds.

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 carbon or fouled, 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 DOLMAR grease may be purchased
from your DOLMAR dealer.)
Suction head in the fuel tank
The felt filler (5) of the suction head is used to filler the fuel required by the
carburetor.
A periodical visual inspection of the felt filler is to be conducted. For that
purpose open the tank cap, use a wire hook and pull out the suction head
through the tank opening. Filters found to have hardened, been polluted or
clogged up are to be replaced.
Insufficient fuel supply can result in the admissible maximum speed being
exceeded. It is therefore important to replace the felt filler at least quarterly
to ensure satisfactory fuel supply to the carburetor.
Cleaning of muffler exhaust port
Check of muffler exhaust port (6) regularly.
If it is clogged by carbon deposits, carefully scratch the deposits out with a
suitable tool.
Any maintenance of adjustment work that is not included and described in this
manual is only to be performed by Authorized Service Agents.

STORAGE
When keeping the machine in storage for a long time, drain fuel from the fuel
tank and carburetor, as follows: Drain all fuel from the fuel tank. Dispose of
properly and in accordance with all local laws.
Remove the spark plug and add a few drops of oil into the spark plug hole.
Then, pull the starter gently, so that oil covers the engine inside and tighten
the spark plug.
Clear dirt or dust from the cutter blade and outside of engine, wipe them with
a oil-immersed cloth and keep the machine in a place as dry as possible.
