FUELS/REFUELLING
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 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!
Fuel and oil mixture
The engine of the Brush cutter or Grass trimmer 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 to use specified
two-stroke engine oil at mixture ratio of 50:1 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 50:1 (specified 2-stroke engine oil), as otherwise reliable function of the
Brush cutter or Grass trimmer cannot be guaranteed.
The correct mixture ratio:
Gasoline : Specified two-stroke engine oil = 50 : 1 or
Gasoline : Other manufacturers two-stroke engine oil = 25 : 1
recommended
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 or Grass trimmer 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.
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 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.
Observe the Safety Instructions on page 4!

Firmly hold the clutch case by your left hand, as illustrated.
Slowly pull the starter grip until resistance is felt and continue with a smart
pull.
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.
When the engine starts, please open the throttle lever a little. The choke
button being automatic, it returns to original position .
Run the engine for approximately one minute at a moderate speed before applying full throttle.
Note: If the starter handle is pulled repeatedly when the choke button remains at position, the engine will not start easily due to
excessive fuel intake.
In case of excessive fuel intake, remove the spark plug and pull the starter handle slowly to remove excess fuel. Also, dry the
electrode section of the spark plug.
Caution during operation:
If the throttle lever is opened fully in a no-load operation, the engine rotation is increased to 10,000rpm or more. Never operate the engine at a
higher speed than required and at an approximate speed of 6,000 - 8,000rpm.
Starting the warm engine
As described above, except without moving the choke button.
Stopping
Release the throttle lever (2) fully, and when the engine rpm has lowered,
push the I-O switch (1) to O position the engine will now stop.
Be aware that the cutting head may not stop immediately and allow it to slow
down fully.
IDLE ADJUSTMENT
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 Idling speed
Idle speed should be set to 3,000rpm.
If necessary correct it by means of the idle screw (the blade or the nylon
cutting head must not turn when the engine is on idle).
Screwing in the screw (1) will cause an increase in the engine speed,
whereas backing off the screw 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))
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. 6,000rpm.
Low speed (under 4,800rpm) 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 throttle lever to run the engine idle 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 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.
Replacing the nylon cord
First, stop the engine.
Press on 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, leaving the ends
temporarily hooked through a 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. Keep the side with letters on the
spool visible on the top. Now, unhook the ends of the cord from their
temporary position and feed the cords through the eyelets to come out of 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
COUTION: Before doing any work on the Brush cutter or Grass trimmer, always switch off the motor and pull the plug cap off the spark plug
(see checking the spark plug).
Always wear protective gloves!
To ensure a long service life and to avoid any damage to the equipment, the following servicing operations should be performed at regular
intervals.
Daily checkup and maintenance
Before operation, check the machine for loose screws or missing parts. Pay particular attention to the tightness of the cutter blade or nylon
cutting head.
Before operation, always check for clogging of the cooling air passage and the cylinder fins.
Clean them if necessary.
Perform the following work daily after use:
Clean the Brush cutter or Grass trimmer externally and inspect for damage.
Clean the air filter. When working under extremely dusty conditions, clean the filter the severall 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 idling and engagement speed to ensure that the cutting tool is at a standstill while the
engine is idling (if necessary reduce idling speed).
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.
Cleaning of air cleaner
Clogging of the element (1) may sometimes make it difficult or impossible to
start up the engine or increase the engine speed.
After the end of operation, be sure to clean the air cleaner as mentioned below.
Remove the air cleaner cover screw.
Place the finger under the air cleaner cover, push down the cover lower part,
and detach the air cleaner cover.
Take out the element (1), clean it with lukewarm water mixed with neutral
detergent, and dry it completely.

After cleaning, attach the element.
Insert the claw at the case upper part into the hole at the upper part of the air
cleaner cover. Then, attach the air cleaner cover by pushing it, and tighten
the screw (2).
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 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 carbon or fouled, clean it thoroughly or replace it.
COUTION: 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 (1) of the suction head is used to filler the fuel required by the
carburetor.
A periodical visual inspection of the felt filter 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 filter at least quarterly
to ensure satisfactory fuel supply to the carburetor.
Cleaning of muffler exhaust port
Check of muffler exhaust port (2) 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 the machine is 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 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 or the nylon cutting head and outside
of engine, wipe them with a oil-immersed cloth and keep the machine in a
place as dry as possible.
