PACKING AND TRANSPORT
◊ WIDTH: 100 cm. ◊ DEPTH: 47 cm. ◊ HEIGHT: 63 cm.
-Fig.n.4-
• Remove the power mower from its packing.
• Fix the handles to the handlebar support using the two screws and
two knobs pre-mounted on the handle. Make sure to position the
control cables correctly.
• Fix the bar to the machine, removing the hooked spring (Fig.4
Ref.A) located on the pin of the bar support (Ref.B). Insert the pin
of the bar support into the frame (Ref.C) and reinsert the spring
(Ref.A) in the direction of the hole. Take the plastic cylinder (Fig.4
ref.D), insert it into the grass divider (Ref. E) and insert all into the
pin of the bar (Ref.F) correspondingly to the hole on the grass
divider and on the cylinder. Fix the grass divider (Ref. E) to the bar,
inserting two screws (Ref.G) into the threaded holes on the bar
corresponding to the grass divider.
• If the machine is to be transported, empty out the petrol tank and always apply the plastic protective strip to the
E.S.M. cutting bar blade. Read the E.S.M. sheet attached.
IMPORTANT: THE PACKED MACHINE IS SUPPLIED WITH THE MOTOR WITHOUT OIL OR PETROL.
SAFETY RULES
• Read carefully the operation and maintenance manual enclosed with the machine.
• The use of the machine is prohibited to persons under 16 years of age.
• The operator is liable for damages since the machine is under his control.
• Those unfamiliar with the machine or who have never used it are obliged to read the operation and maintenance
manual before operation.
• In case of transport, disassemble the bar and empty the petrol out of the tank.
• If the machine is left unattended, ensure that it cannot start up again.
• Before running the machine, the operator must have a 5 meter radius of free space around him.
• Dry any petrol leaks.
• Fill up the tank with the motor off. Filling the tank or transferring fuel must always be performed outdoors, away from
flames or heat sources. Do not smoke during this operation.
• When mowing in mountainous areas or on slopes, mow horizontally and use non-skid equipment on shoes and wheels.
• If the blade needs replacement, observe E.S.M. operation and maintenance procedures.
• If the bar suffers impact, check the condition of the bar before resuming work.
• Keep feet and hands far away from the cutting bar and all rotating parts.
• Do not run the motor where exhaust containing carbon monoxide may accumulate.
• Never use the mower incomplete or without its safety device.
• Do not assemble/disassemble or clean the cutting bar or other equipment with the motor running.
• Caution! When the clutch is engaged the cutting bar is always in motion.
• Caution! Do not mow areas with slopes exceeding 30%.
• We will not be held liable for accidents caused by the failure to observe these rules.
STARTING AND STOPPING THE POWER MOWER
Every time you get ready to start the motor, make a careful check of the following:
• Make sure that fuel is in the tank.
• Check the motor oil level: CAUTION: MACHINES OUT OF THE FACTORY DO NOT
CONTAIN OIL IN THE MOTOR. Make sure to add oil up to the level on the dipstick.
• CONSULT THE OPERATION AND MAINTENANCE MANUAL OF THE MOTOR UNDER
"BEFORE START-UP"
• Check that all safety systems are released and functioning.
• Start the machine always in the open air and stay at its side.
• Bring the accelerator hand lever (Fig. 5) to the "MAX" position, grasp the cord handle
(Fig. 6) and pull it slightly until you feel some resistance, then pull harder. Make sure
that the cord does not return by itself -- accompany it with your hand.
• With the motor running, bring the accelerator lever (Fig. 5) to the middle position To make the machine go forward
squeeze the clutch lever (Fig. 7 Ref. B) ; if you leave the lever, the machine stops.
• To move the mower freely forward or back, squeeze the wheel release lever (neutral position) after squeezing the
clutch lever.

SAFETY DEVICE FOR STOPPING THE MOTOR
The main function of the lever Fig. 7 is to turn off the motor when releasing your hands from the steering handles.
Every time you get ready to start the motor, check if the engaging and disengaging of the transmission to the wheels
and to the bar through the levers on the handlebars work regularly.
-Fig. n°6- -Fig. n°7-
OPERATING AND REGULATING THE MACHINE
Before you start mowing, oil the cutting blade, then start the motor as follows:
• Engaging the transmission to the wheels and the cutting bar by means of the clutch lever must be carried out with
the motor at a middle r.p.m. and by slowly releasing the lever.
• When starting to mow, position the accelerator lever at 3/4 or at "MAX" to ensure adequate power.
• When mowing along a wall or the edge of a sidewalk, be careful to keep a safety distance so that the blade does not
suffer impact. If not, the cutting bar may undergo damage.
• If the belt slips, loosen the register located on the clutch lever and leave a travel of approximately 5 mm before the
clutch engagement.
• Adjusting the height of the handles is carried out by moving the knobs securing them on the handlebar support. This
will allow two positions (Fig. 1 Ref. 10).
• To regulate the motor, read the manual on the motor under "REGULATIONS".

MAINTENANCE
• For changing the oil and other maintenance operations on the motor (spark plugs, air filter, regulations), refer to the
motor manual provided.
• NB: To unscrew the oil drain plug of the motor, disassemble the rear cover (Fig. 8 Ref. D).
• Empty the gearbox of oil by unscrewing the oil drain plug, let the oil drain completely. After screwing back the cap
tightly, fill to the correct level with new oil recommended by the manufacturer.
• Do not leave the exhausted oil in the environment.
• Check periodically the oil level and fill in with new oil if necessary.
• If the grass is not cut in a satisfactory manner despite the adjustments, the blade must be sharpened or replaced.
Follow the instructions on the E.S.M. maintenance sheet.
• For any mechanical repair, especially during the warranty period, we recommend to go to a specialized repair shop of
the dealer.
• For transporting convenience, the handles can be disassembled by means of the two knobs (Fig. 1 Ref. 10). The
same is recommended for the cutting bar, which is easily disassembled by removing the special split pin on the bar
support (Fig. 9 Ref. E). Always use gloves and apply the protective strip to the blade.
• Regularly check that screws are tight. Pay special attention to the screws fastening the bar to its support.
• Lubricate periodically the crown wheel for the wheel transmission (Fig. 9 Ref. “F”).
CAUTION:!!
It is advised not to keep the motor running when the machine is not
being used for its specific purpose
