Sharpening The Blades; Pto Belts - Grillo FD 2200 4WD Manual De Instrucciones

FD2200 4WD/ Translation of the original instructions
EMERGENCY AND PARKING BRAKE OIL
Every 50 hours check the brake oil level in the reservoir on the left side of the driving seat (fig. 40). If
necessary, add brake oil DOT4 (total quantity 0.5 litres). Periodically check the braking system to make sure
there are no leakage.
Whenever it is necessary, carry out the air bleed procedure. If you have the proper tool, connect it at the
place of the reservoir cap. If you have to carry out the bleed without the proper tool proceed as follows:
1) Put the oil into the reservoir.
2) Press the emergency brake pedal 3 times (fig. 1 no. 3): keeping the pedal pressed, slightly unscrew the
drain plugs on the calipers to let the air out.
3) Repeat the procedure twice, until the circuit gets under pressure when pressing the pedal.
4) Attention, the brake pedal has to have a little clearance to prevent that the circuit is steadily kept in
pressure, which would damage the brakes.
NOTE: Use the brake pedal only in case of emergency. To stop, just release the feed and reverse pedal.

SHARPENING THE BLADES

For the cutting deck check and maintenance proceed as follows:
1) lift the cutting deck hydraulically;
2) release the two side shock absorber (fig. 11);
3) lift the cutting deck by hand and hitch it with the special lever (fig. 22).
You do not need to release the universal joint nor the deck loading duct. Before starting the machine, make
you sure that the universal joint is well connected and that the stop push button is protruding.
A blunt blade pulls at the grass giving it an unsightly appearance, the cutting edges of the blades must
therefore be kept sharp at all times. As the blades wear they lose their cutting efficiency and tend to become
unbalanced, causing the lawnmower to vibrate; sharpen both blades uniformly.
When you substitute the blades, it is compulsory to substitute also the screw and respective nut (fig. 23). Do
not lock the blade ends: they must be without play, but free to float if they hit against something. In
order to avoid damaging the blades, the torque of the blade pin must be of 90 Nm.
To remove a blades' disc, hold it firmly using safety gloves and unscrew the fixing plate and the central
screw. 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.
