WARNING: PLEASE BE SURE THAT THE BLADES NUTS HAVE BEEN TIGHTENED
ACCORDING TO THE FOLLOWING TIGHTING VALUES:
NUTS FIXING DISC

NUTS FIXING BLADES

1)
Keep the angle of original sharpened edge (23°)
2)
Do not grind the same blade part excessively in order to avoid changing the properties of the blade due to excessive
heat
3)
Do not excessively grind the material: this will shorten the blades life.
PERFECT CUT IS OBTAINED ONLY WHEN THE BLADES ARE CORRECTLY SHARPENED.
Sharpening frequency varies in accordance with cutting conditions: frequent sharpening is obviously required when
using the machine on stones, sand, mould.
When remounting sharpened or new blades make sure that the blades on one disk are mounted 90° to the blades on the
other disk. Obviously respect cutting direction and remember that the left-hand blade turns counter-clockwise and the
right-hand blade turns clockwise, when operators stand in front of the mower deck as shown in the above picture.
Before any operation on the mower deck for repairs, servicing, cleaning, adjustments and others, disengage the PTO,
stop the engine and remove the key.
16 – HYDRAULIC LIFT FOR FRONT ATTACHMENT
Technical features
The machine is equipped with a hydraulic front lift. It is composed of an oloedynamic pump assembled in parrallel on
the hydrostatic transmission, acting through the distributor on two plunging pistons which are able to lift the front
attachment by means of an equalizer-rod unit.
Use
See chapter 10.
Maintenance
No particular maintenance is required. Just periodically check the oil
quantity in the circuit.
This is done by checking the level through the transparent indicator at
the side of the tank. The indicator shows the oil level.
Oil quantity and quality: see chapter 21.
The unidirectional valve hole, indicated on side picture point 1, may
become clogged by impurities in the oil. In this case and with the
lever in the floating position (forwards) the front attachment lift will
be inhibited during descent phase.
Proceed in the following way to restore correct operation:
1) Remove the valve from the pipes to which it is connected, making
note of the connection direction. The tip of the cone points towards
the pipe that leads to the distributor. Pay attention to the sudden
descent of the attachment as soon as the valve is removed.
2) Clean with compressed air (or by means of a needle) in order to
eliminate the clogging impurities.
3) Remount the valve in its original configuration.
