Sharpening The Blades; Adjusting The Cutting Deck; Pto Belts - Grillo FD 1500 2WD Uso Y Mantenimiento

LUBRIFICATION POINTS WITH GREASE
Lubricate with grease every 40 hours the rear axle pivots, the pedals, the PTO transmission belt guide pulley, the
pivot connected to 2 points of the cutting deck, basket lifter arms.
EMERGENCY AND PARKING BRAKES OIL
Check every 50 hours the brakes oil level in the oil pan, which is positioned on the left side of the driving seat (Fig.
40). If you need it, add brakes oil DOT4 (total quantity lt. 0,5). Check periodically the brakes system in order to be
sure there are no oil losses.
How to do the cleaning if this operation is necessary: if you have the tool, please connect it in place of the oil pan plug.
If you have to do the cleaning without the specific tool, use the emergency brake pedal of the machine; please do as follows:
1) Put the oil in the pan.
2) Operate for 3 times on the pedal; keeping the pedal pressed and open lightly the cleaning screws on the
brake clippers in order to let the air go out.
3) Repeat the operation 2 times, until the pedal device keeps the pressure.
4) Attention please! The brake pedal must have a bit of clearance, in order not to keep the device in pressure,
causing the brakes damage.
NOTE: Please use the brake pedal only in emergency case, usually in order to stop the machine you only
have to release the forward and reverse gear pedals.

SHARPENING THE BLADES

To the cutting deck check and maintenance proceed as follows:
1) lift hydraulically the cutting deck;
2) release the two side brackets;
3) lift the cutting deck by hand and hitch with the special lever (fig. 22). You do not need to release the universal
joint and the load pipe.
When you substitute the blades, it is compulsory to substitute also the screw and respective nut (fig. 23).
Do not lock the blades to the plate: they must be without play, but free to float if they knock against
something.
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 the blades uniformly.
To remove a blade-box disk, hold it firmly using safety gloves and undo the centre screw. Caution: the right disk
central fixing screw has a left-handed thread (fig. 23).
Before starting the machine, make you sure that the universal joint is good connected and that the stop push
button is protruding.
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 on the two floating springs (fig.
24), and if necessary use the screws to adjust them.
If a satisfactory parallel set up cannot be achieved, contact an Authorised Service Centre.
The two floating springs also give greater traction to the drive wheels, especially on a slope.
To remove the deck from the mower, undo the side bracket (fig. 11) and the two pins (fig. 25).
ATTENTION! When the two pins are unhooked, please remember to keep the two cutting deck lifting arms
pressed strongly, because they go off and they can be very dangerous.
Unhook the two lateral springs on the charge tube and pull forward the whole cutting assembly, unscrew the load
pipe from the turbine. Caution! When refitting the deck always remember to reconnect the universal joint,
the charge pipe must be screwed for 2 complete turns.

PTO BELTS

Caution! These belts are special, use original belts.
To replace them the procedure as follows: loosen the tie rod and remove the clutch locking screw.
If the belts remain slack even though the adjusting nut is tight, fit spacing washers between the PTO transmission
and the bracket.
