FD2200 4WD/ Translation of the original instructions
Caution: the right blade central fixing screw has a left-handed thread (fig. 23).
Caution! Always replace damaged or bent blades; never try to repair them! ALWAYS USE ORIGINAL BLADES!
ADJUSTING THE CUTTING DECK
An even deck is essential for achieving a uniform cut over the whole lawn.
With the lawnmower on a flat surface, check the tyre pressures, check the tension of the two deck floating springs
(fig. 24) and act on the adjusting screw if necessary. If a satisfactory parallel set-up cannot be achieved, contact an
Authorised Service Centre. The two deck floating springs also give the drive wheels a better grip, especially on
slopes.
To remove the deck from the mower, undo the two side brackets (fig. 11) and the two pins (fig. 25).
Attention! When the pins are unhooked, please remember to keep the two cutting deck lifting arms pressed
strongly, because they jump up and can be very dangerous.
Unhook the two lateral springs on the grass loading duct and pull forward the whole cutting deck, unscrew the
loading duct from the turbine. Caution! When refitting the deck always remember to reconnect the universal
joint, the loading duct must be screwed for 2 complete turns and does not have to hit the turbine wheel.
PTO BELTS
Attention! These belts are special, USE ORIGINAL BELTS.
To replace them, loosen the tie rod and remove the clutch locking screw.
To set the tension use a no. 13 spanner to turn the nut that adjusts the tension spring (fig. 5, ref. A).
The spring must be compressed at 92 mm length.
CLUTCH-BRAKE FOR PTO
The FD2200 4WD is provided with a multi-disc electro-hydraulic clutch for PTO (fig. 51) activated by an electric
push-button on the dashboard (fig. 2 no.8).
During work, with the PTO engaged, the friction material discs are pressed against each other by the oil pressure.
To make this happen, the working pressure is calibrated at 7 bar. All clutches are tested in pressure to prevent oil
leakage in the components. This construction design guarantees a long working life and a gentle activation.
In order to meet security requirements, the clutch for PTO has a brake that stops the cutting blades within 5
seconds from the moment the clutch is disengaged. Due to the wear of the brake friction material (fig. 51 no.3)
blades may need more than 5 seconds to stop, in that case it is necessary to re-establish the distance between the
disc (fig. 51 no. 4) and the plate (no. 5) to 36.5 mm as per factory calibration. Carry out this intervention with the
machine turned off.
How to carry out the calibration:
1) Turn off the machine.
2) Loosen the counter-ring (fig. 51 no. 1).
3) Bring the distance between the disc (fig. 51 no. 4) and the plate (no. 5) to 36.5 mm by acting on the ring (no.2).
4) Lock the counter-ring (fig. 51 no.1) against the ring (no.2).
After adjusting it, make sure that the blades stop in less than 5 seconds. If the blades take 5 or more seconds to
stop contact an Authorized Grillo Dealer because the machine does not meet the safety standards and cannot be
used in a safe way.
GRASS CATCHER LOCKING HOOK
The grass catcher locking hook may be adjusted with the respective screw. Please leave a small, 2 mm clearance
to make the hooking easier when closing.
