GF3 – Translation of the Original Instructions
GEARBOX – Check the oil level (Fig. 4) every 50 working hours by removing the cap and checking
with the machine in horizontal position that the oil is between the two notches. If necessary add
MP 85W/90 (US MIL-L-2105D) oil. Change the oil once a year or every 200 hours.
TIPS FOR A PROPER USE
1)Do not damage the machine's implement centring device. Always keep it clean and greased.
2)Never leave the machine out in the rain.
3)Do not force the gear if gears do not engage: when inserting the gear press the clutch lever a
little.
4)Never strain the engine. If smoke comes out of the exhaust pipe, it is recommended to slow
down.
5)Even difficult grounds can be worked. However the machine must be well run-in first.
6)Never work at max. r.p.m..
7)Often sharpen the blades. To do this, pull the blades out from the bar by first removing the blade
coupling.
END OF SEASON MAINTENANCE
Clean the machine carefully, change the engine and gearbox oil. Clean the air filter. Sharpen and
grease the blades and the cutter bar.
Thanks to its very light weight, the GRILLO GF3 sickle bar is ideal for mowing on slopes where
easy handling is needed.
The cutter bar is available in 110 – 115 – 117 – 127 cm. Four kinds of cutter bar with four different
types of teeth are available:
- teeth with sharp tip (semi-dense arrangement).
- MULCHING – TIROL teeth without sharp tip.
- double blades (without vibrations).
The cutter bar without sharp teeth is provided with side skids used to adjust the cutting height.
TIROL and MULCHING double blades bars have two middle slides for cutting height adjustment.
This teeth allow easier mowing where grass has already been cut without clogging the blade.
Cutter bar maintenance
Grease the blade movement block using the greaser every 8 working hours (fig. 8). The
transmission box should also be greased every 8 working hours using the greaser on the side of
the guard. Keep the blade correctly adjusted by regulating the blade holders; they must not be so
tight that they lock the blade, but the clearance in relation to the teeth plates must not be
excessive. To adjust the blade holders on both types, back off the holder retainer screw by the
necessary amount (fig. 7 – 9).
The blade holders should be replaced when worn even if they are still able to apply pressure.
Regulate the clearance between the blade and the wear strip by loosening the screws securing the
strip retainers and moving the strip forward until it touches the bar holding the blade sections in
place. Then re-tighten the strip retainers. To remove the blade, take out the screws (fig. 8), remove
the blade connection and slip off the blade. Take care to tighten the fixing screws of the coupling
after fitting the blade again. Always use sharp blades: the machine will not strain and will last
longer. After every working day wash the cutter bar removing any remaining piece of grass or mud;
check occasionally that all screws are tightened.
