Sharpening The Blades - Grillo FD 2200 stage 5 Bedienungsanleitung

The oil must be changed before the first 500 hours if:
the oil is black;
-
- the oil has a whitish colour (it is contaminated with water);
- there is black residue (partial oil deterioration).
To remove the oil undo the lower oil reservoir plug (fig. 20). To fill it in, unscrew the upper cap (fig. 6, ref. B).
Pay attention to possible impurities, which may get into the circuit, causing serious problems to your
machine.
When you change the hydraulic oil, you must also change the oil filter (fig. 46). Do not increase the drive
wheels hydraulic system pressure over 280 bar; the hydraulic pump and the hydrostatic engines on the
wheels may be damaged. To regulate the cutting deck and the grass catcher hydraulic pressure you must
work on the screw with jam nut located on the hydraulic distributor. This operation must be carried out by an
Authorized Service Centre (max. pressure 230 bar).
155 cm CUTTING DECK GEAR BOXES
Use synthetic oil LSX 75 W 90 (API GL4 + GL5; API MT1 and PG2), 1.550 litres, to be changed every 300
hours. The oil level plug is positioned over the gear boxes.
If you notice any leakage, check and replace the oil seals to avoid the deterioration of the entire
transmission.

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. 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 (red arrow).
