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"
•Make sure oil is up to the level in the gearbox (Picture 5 Ref. A)
•Check that all safety systems are released and functioning, especially the levers Ref. B and Ref. C Picture 6
•Always start the motor up outdoors.
•Bring the accelerator hand lever (Picture 6 Ref. "A”) to the "START" position, grasp the cord handle (Picture 7) 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.
•For best start-up, read the operation and maintenance manual on the motor under "START-UP".
•With the motor running, bring the accelerator lever (Picture 6) to the middle position.
•To make the machine go forward squeeze the clutch lever (Picture 6 Ref. B). Release it slowly and the machine will start
operating, keeping the "MOTOR STOP" lever pressed.
•In order to engage the bar, press the security button with the thumb (Picture 6 Ref. H) and with the palm of the hand let the
bar clutch lever down (Picture 6 Ref. C) keeping it pressed on the handle.
•To move the mower freely forward or back, squeeze the wheel release lever (Picture 6 Ref. B) after squeezing the clutch
lever (Picture 6 Ref. D).
•To switch off the engine, move the accelerator lever (Ref. A Picture 6) to the "STOP" position.
•The main function of the lever Ref. "e" Fig. 6 is to turn off the motor when releasing your hands from the steering handles.
Do not ever tie the "MOTOR STOP" lever "e" to the handlebar knob.

Before beginning to mow grease the moving bar with oil. Then start up the engine following the directions.
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 belts are slipping, operate on the adjustment devices (Ref "E" Picture 6) which are on the clutch levers. Leave a gap
of about 5 mm before the clutch engage. To adjust the wheel releasing cable, operate on the adjustment device "F" (Picture
6)
It is possible to adjust the handle vertically, by acting on the knobs that fix it to the handlebar support: two different positions
are available (Picture 8 Ref A).
It's possible to have another little vertical adjustment of the handle, by rotating the handlebar support, after having loosened
the screws that fix it to the transmission box. Then screw tight again. (Ref. "B" Picture 5)
To regulate the motor, read the manual on the motor under "REGULATIONS".

•Make a regular check of the oil level in the gearbox with the cap (Fig. 5 Ref. A) and topping up if necessary.
•Change the oil completely every 200 hours. Empty the gearbox of oil by unscrewing the oil drain plug (Fig. 5 Ref. C)
•Let the oil drain completely. After screwing back the cap tightly, fill to the correct level with new oil recommended by the
manufacturer. Fig. 5 Ref. "A".
•If the grass is not cut in a satisfactory manner despite the adjustments, the blade must be sharpened or replaced. For
replacement as follows :
1. Remove the cable of motor spark plug.
2. Put on a pair of gloves.
3. Unscrew the grass divider (Fig.1 - Ref. “6”).
4. Loosen the 4 knife holder.
5. Remove the blade and put the new or the sharpened one, only after having greased it.
6. Rescrew the knife holder, adjusting them in such a way as the blade can slide well.

•For any mechanical repair, especially during the warranty period, we recommend to go to a specialised repair shop of the
dealer.
•For transporting convenience, the handles can be disassembled by means of the two knobs (Fig. 8 Ref. A). The same is
recommended for the cutting bar, which is easily disassembled by removing the special split pin on the bar support (Fig. 9).
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
