ENGINE OIL
Follow the instructions on the "Engine operator's manual" carefully. It is however necessary to check the oil lever
every 4 hours taking the plug off (Fig. 6, n° 1). Change lubricant the first time after 20 hours. Then change it every
50 hours. Unscrew the plug (Fig. 6, n° 2).
GEARBOX OIL
Check the oil level every 50 working hours unscrewing the screw (Fig. 7, n° 3). If necessary add some SAE
85W90 lubricant. Change the oil once per year. To drain the oil unscrew the plug (Fig. 8, n° 1).
MAINTENANCE
After the first working hours, it might be necessary to check and adjust the wheel releasing cable and the re-
versing device cable acting on the adjuster situated on the handle (Fig. 1, n° 7).
The quick coupling must be always clean and greased. To remove the fairing pull upward. The same for the
cutter bar conveyor.
END OF SEASON MAINTENANCE
Wash the machine carefully; change the oil in the gearbox housing, clean the air filter, wash the cutter.
CUTTER BAR
The cutter bar attachable to this machine is with central control (fig. 11). Its strong construction and high perfor-
mances make it the ideal means to mow small pieces of land, parks and gardens.
The cutter bar must be fixed to the attachments coupling just by means (fig. 4): by the lever.
MAINTENANCE
– Check the blade holders are always well adjusted (fig. 12, F) but not too tight because the engine might
stop once the cutter bar is engaged and the cutter bar could be damaged by overheating. The blade must turn
by operating the hand-wheel.
– Check the blade is well sharpened.
– Sharpen the cutting edges on the upper side (fig. 13).
– Check the blade movement is always properly tightened and lubricated while working. Lubricate with
each cutter bar (fig. 14).
– When work is finished the cutter bar must be washed and lubricated.
SAFETY DEVICE FOR CUTTER BAR (FIG. 16)
On the GF1 cutter bar a safety device has been assembled in order to protect the cutter bar itself if a foreign
body suddenly stops the blade. If, after a certain period of work, and after several sudden stops on the blade, the
cutter bar does'int work as well as before, it is necessary to add one or two schims 0,5 mm. under the washer
(see the picture below in order to adjust the spring pressure on the couplings.
Actions:
1) Disconnect the cutter bar from the machine using the attachment blockage lever (fig. 4).
2) Unscrew the screw nr. 1 (fig. 16).
3) Estract the wascher nr. 2 (fig. 16).
4) Add one or more shins 0,5 mm.
ROTARY CUTTER
This implement (fig. 12), specially studied for parks and gardens maintenance, has a cutting width of 50 cms. Its
high power and the driving wheels allow to operate in all conditions without tireing the operator. The rotary cutter
is attachable to the implement frame instead of the cutter bar.
The transmission of the movement to the blade is obtained by a bevel gear pair. The lawn mower is equipped
with a releasing device on the coupling, in order the machine is not damage.
Cutting height can be regulated adjusting the position of the little wheels of the rotary cutter, or of the lateral rams,
thus changing the blade height from the round (fig. 13).
