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 o’clock.

– Never apply the brush cutter within a segment between 12 and 2 o’clock.

– 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 o’clock presents

positive hazards, especially when using metal cutting tools.

– Cutting operations within a blade segment between 11 and 12 o’clock, and

between 2 and 5 o’clock, 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 o’clock.

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.

(2)

(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.

– 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”.

• 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,

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.
