- 3 -
6. Keep people and animals away from working area
(minimum distance 15 meters).
If somebody should approach you, turn the engine off and
stop the blade (see section STARTING AND STOPPING
THE ENGINE), as during operation the blade or the nylon
string head might project grass, grit or other debris. The
blade is sharp. Be careful even if handling it when the
engine is off. Wear heavy-duty gloves. Turn the engine
off and wait for rotating parts to stop completely before
working on the machine or before touching the blade or
the string head.
DO NOT USE THE BRUSH CUTTER AT ALL, IF THE
SPECIFIED SAFETY GUARD IS NOT FIRMLY
ATTACHED (see sections SAFETY USAGE and
BLADES AND NYLON STRING HEAD ASSEMBLY).

might put your life or somebody else’s in danger as a
result of:
a) possible contact with cutting or rotating parts,
b) possibility of projection of various objects
WARNING: Do not start engine if it is not attached to
the shaft, as the clutch might disintegrate.
[3] SAFETY USAGE
This product must be held to the right of the operator’s body.
This will exhaust fumes are directed away from the operator
and will not be obstructed by the operator’s clothing. If you
have not used a brush cutter before, spend some time in
becoming familiar with the controls and method of usage
before operation. Check the machine carefully before using
it. Make sure that there are no loosened screws, damaged
parts or fuel leakages. Replace damaged or excessively worn
accessories (blades, string heads, GUARDS).
Ensure all maintenance and repair work are carried out by an
authorized service center. Check the condition of the
antivibration components on a regular basis.
N.B. In order to maintain performance and safety, be sure to
use original spare parts and accessories. Avoid using the
brush cutter over excessively long periods of time.
Excessive amounts of vibration can be harmful.

1. Remove from the work area grit debris ropes, metal parts
or any other object which might get entangled along the
rotating parts or be dangerously projected. Before starting
to work, fir the harness correctly. Adjust harness with the
buckle so that the brush cutter is well blanced on your
right side and the blade or string head is parallel to the
ground.
Ensure the pole barrier is correctly assembled (on units
supplied with one).

- 4 -
2. The following accessories can be assembled to your brush
cutter. a) blade, b) nylon string head.
a)WHEN USING A BLADE, ENSURE THE CORRECT
GUARD IS FITTED.
b)WHEN USING A NYLON STRING HEAD,ENSURE
THE CORRECT GUARD IS FITTED.
When using the unit hold the front part of the machine
(blade or nylon string head) below your waist.
NYLON STRING HEAD:
Always make sure it has been correctly assembled (see
section ASSEMBLY and relevant chart).
The nylon string head is suitable to mow a lawn to trim grass
and weeds on edges or wherever there might be obstacles
like trees, fences or walls.
The nylon string head also reduces the likelihood of
damaging small plants and trees bark.
BLADE:
Always make sure it has been correctly assembled (see
section SAFETY and ASSEMBLY and relevant chart).
When fitting or changing a cutting device, ensure you follow
the instructions in the section “fitting a blade or nylon string
head” with extreme precision. Fit these cutting devices using
all and only the parts described, and in the correct order.
Fig.3-2
Fig.3-3
3.BLADES:
You can cut any type of grass, bushwood or shrub.
Operate the machine like a sickle always cutting at full
throttle.
N.B. This machine is designed so that the blade or nylon
string head is mounted for rotation in the anticlockwise
direction.
Fig.3-4
4. WARNING: Always use a well sharpened blade.
A blade with worn teeth besides providing poor
performance, might also generate a sudden thrust. This
can result in a violent sideways kick caused when the
blade touches against solid bodies. Such thrust might then
cause the operator to lose control of the machine itself. Do
not attempt to use a damaged blade but replace it with a
new one.
THRUST: Can occur when using any type of blade
within the risk area
; therefore it is advisable to cut
using the remaining area of the blade.

petrol mix it with 2% (50:1) of high quality synthetic oil
specifically made for 2-stroke engines.
IMPORTANT:Always shake this fuel mix vigorously
each time you use it.
Fuel mix properties deteriorate with time. We therefore,
recommend that you only make the quantity of fuel mix
you will need for each usage. Do no use fuel mix more
than a week old, as this could damage the engine.
WARNING: Do not smoke when re-fuelling.
Always open the fuel cap slowly.
Re-fuel in open spaces only, keeping away from naked
flames or sparks.
Always store fuel in an approved container.
Safety storage of fuel
Petrol is highly inflammable. Put out all cigarettes, pipes
and cigars before working with petrol. Avoid spilling
petrol. Store fuel in a cool well ventilated place, in an
approved container specifically designed for the purpose.
Never store engine with fuel in the tank in enclosed,
poorly ventilated areas, where fuel fumes may reach an
open flame, spark or pilot light such as in a furnace, water
heater, clothes dryer, etc. Petrol fumes can cause an
explosion or a fire. Do not store large amounts of fuel.

A dust clogged air filter may cause carburetor problems.
This may prevent the engine from reaching its maximum
r.p.m. and cause high fuel consumption and/or difficult
starting. Remove filter cover. Carefully clean the inside of
filter box. The filter can also be cleaned with compressed air.
2. GEARCASE
Every 50 working hours inject the gearcase with gear grease
under high pressure through hole A.

From time to time (at least every 50 hours) remove and
clean the spark plug and check the electrode cap. Replace
spark plug about every 100 working hours or whenever it is
extremely encrusted.
Heavily encrusted electrodes can result from an incorrect
carburetor setting or from wrong fuel mixture (too much oil
in the petrol) or a poor quality oil in the fuel mix. Check and
correct.
Please refer to the Engine Operation Manual for information
about changing the spark plug and the electrode cap.
