5. GENERAL WARNINGS TO KEEP IN MIND
WARNING:Readcarefullybeforeoperatingthemachine.
Cautionisthemainrequirementinaccidentprevention!Carefully
read the following warnings when using the machine, even
before starting work. Improper use can be dangerous. Observe
thefollowingprecautions:
• Read this manual completely before starting and running the
machine;
• Before handing the machine over to other people, make them
aware of the safety rules and how to use the machine;
• Pay particular attention to the safety decals on the machine;
• Before starting work, always wear appropriate work wear, long
trousers, gloves, safety shoes and goggles;
• The use of hearing protection equipment is recommended when
using the machine continuously. Use earplugs or earmuffs that
comply with current regulations.
sAfety in the working environment
• Before switching on the machine, check that there are no
animals or people nearby, especially children; the minimum
distance is 15 m;
• Check the area in which the machine is to be used: before
cutting the grass, clear away all objects (stones, branches, etc.)
that could damage the machine or that could be thrown from the
rotating attachment;
• Be careful when working near a road;
• Do not operate near ditches or embankments which may
collapse under the weight of the machine, especially if the
ground surface is uneven or wet;
• Take special care when working on slopes. Do not work on steep
slopes. The handling of the machine is reduced on a slope;
• Do not use the machine in enclosed areas to avoid toxic exhaust
fumes.
driving And behAviourAl sAfety

securely tightened.
further sAfety meAsures
• If you hit a foreign body, disengage the attachment, switch off
the engine, and inspect the rotor for damage. If it is severely
damaged, it must be replaced;
• If the machine begins to vibrate abnormally after a knock,
immediately carry out a general check to identify the reason
for the anomaly. If necessary, request the assistance of an
authorised Grillo workshop;
• The rotation of the cutter rotor is very dangerous, never put your
hands or feet near the rotor while the engine is running;
• The guards installed on the machine (bonnets, plastics, etc.)
must not be removed when working;

rotor;
• Before checking, adjusting, repairing or simply cleaning the
machine, disengage the rotor and switch off the engine;
• Do not change the engine settings, especially the maximum revs;
• Do not have anyone check the machine while you are driving with
the engine running.
fuel And fire hAzArd
• Only refuel outdoors, always switch off the engine, stay away from
sparks or ames, do not smoke! Securely replace tank and fuel
container caps;
• Avoidfuelspills.Afterllingthetankcleanupanyspillageonthe

CAUTION: before starting work, always wear appropriate work
wear,gloves,safetyshoesandgoggles.
1. Adjust the height of the handlebar and carry out the checks listed
above (ref. 9.2 Checks to be carried out before starting the engine);
2. Insert the strings into the rotor and check their length, so that they
do not hit parts of the machine during rotation, thus damaging it
(ref. 13.3 Replacement of the strings on the cutting rotor);
3. Start the engine and move the throttle to maximum revs (g. 4/
MAX);
4. To activate the cutting rotor, press in sequence the PTO lever

9.5 TILT DEVICE
Insomesituations,suchastrimmingedgesornishingnearwalls,itmay
be useful to cut close to the ground. To achieve this there is the TILT
device:byoperatingthelevertotheleftofthehandlebar(g.6/C)itis
possible to release the frame from the central position and tilt it to the
right or left, accompanying the tilt with the handlebar. In this operating
modetherotorwillperformaninclinedcut(g.7,tiltstotheright,leftand
centre position).
Fig. 7
In order to achieve a cut grazing the ground, it is advisable to t the
strings in the lowest setting, with the string holder plate upside down (ref.
11.2 Cutting height adjustment).
9.6 WORK CONCLUSION
When cutting is complete release the PTO lever, then:
1. Move the machine out of the working area;
2. Switchofftheenginebymovingthethrottletothe‘0’position(g.
4/0).
9.7 ORDINARY MACHINE CLEANING
CAUTION: before starting any cleaning operation, always wear
suitableclothingandprotectivegoggles.
CAUTION:whencleaningthecuttingrotor,alwaysensurethat
theengineisswitchedoff.
IMPORTANT:inordertoreducetheriskofre,itisimportant
to keep the engine and muffler area clean of dust and dry grass
residues.
At the end of each job, proper cleaning ensures a long service life for the
machine and prevents most common inconveniences.
The best way to clean the machine is with compressed air in the engine
area and optionally water for the body parts and rotor area.
IMPORTANT: avoid wetting the engine linkages, cables and
handlebarleverswithastrongjetofwater.
9.8 USEFUL RULES FOR CORRECT USE
The machine will work in optimum conditions if certain precautions are
followed.
• Before starting work, check that the rotor and grass guard are
perfectly clean, free of grass and dirt;
• Keep cables and levers always clean of dirt and dust;
• Check the ground for stones, large branches and foreign bodies
before cutting the grass. If possible, remove them;
• Check often the length of the strings: they must not be damaged
andmustbettedcorrectly(ref.13.3Replacementofthestrings
on the cutting rotor);
• Be careful when cutting the grass and slow down if there are
obstacles or areas of very tall grass;
• Pay attention if the engine revs decrease: working is overloaded,
it is necessary to reduce forward speed or cut the grass in several
passes for greater effectiveness;
• The best performance with the trimmer is obtained with strings at
the correct length; furthermore, the square or angular cross-section
of the string will result in less cutting effort;
• Thebestcuttingconditionisonatground.Ifyoucutonaslopebe

10. SAFETY DEVICES
10.1 PTO ACTIVE COUPLING
The machine is equipped with an active coupling system for the operation
of the PTO.
Therefore, to stop the cutting rotor when in operation, simply release the
correspondingredlever(g.6/B).
CAUTION:checkfrequentlythattheactivecouplingfunctions
correctly. When releasing the PTO lever, the rotor must stop
immediately.
If the rotor does not stop immediately, check the lever register adjustment
(ref. 12.1 Adjustment of the PTO, tilt device and handlebar rotation lever
registers) or contact the service centre.
10.2 AUTOMATIC BRAKE ON THE CUTTING ROTOR
The cutting rotor is equipped with a brake system that, when the red PTO
lever(g.6/B)isreleased,ensuresthattheattachmentstopswithin1-2
seconds. If the attachment does not stop immediately, check the brake
adjustment (ref.12.2 Adjusting the automatic brake on the cutting rotor) or
contact the service centre.

11. ORDINARY ADJUSTMENTS
11.1 HANDLEBAR SETTING
Before starting work, it is recommended to position the handlebar in the
most comfortable position and with the greatest control over the machine.
To adjust the height of the handlebar, push down the lever located at the
baseofthehandlebar(g.8),thenmovethehandlebarupordown.To
lock the handlebar in the desired position, release the lever, making sure
that its central pin engages in the notch.
Fig. 8
In certain cutting conditions, such as clearing edges, it may be useful
to rotate the handlebar to the right or left. To rotate it, simply use the
appropriatelever(g.9):bypressingit,thehandlebarcanrotatefreely
and it will be possible to move it to the right, to the left, or to make a
half turn so that it is in the transport position. By releasing the lever, the
column will lock into the corresponding holes in the base.

12.1 ADJUSTMENT OF THE PTO, TILT DEVICE AND
HANDLEBAR ROTATION LEVER REGISTERS
Keeping the levers at the correct tension ensures proper operation of the
machine controls.
By loosening the lock nut and unscrewing or screwing the relevant
adjuster, it is possible to adjust the tension of the cable connected to the
leverofthetiltdevice(g.12/A),thehandlebarrotation(g.12/B)andthe
PTO(g.12/C).

12.2 ADJUSTING THE AUTOMATIC BRAKE ON THE
CUTTING ROTOR
To access the brake on the cutting rotor, remove the front cover of the
machine. If, when releasing the PTO lever, the cutting rotor does not stop
immediately, then slightly unscrew the nut on the threaded rod connected
tothebrake(g.13).If,ontheotherhand,whenpressingthePTOlever
the brake pad remains too close to the pulley, causing it to keep friction
during the rotation of the rotor, then further tighten the nut on the threaded
rodconnectedtothebrake(g.13).
