MAINTENANCE AND LUBRICATION

CAUTION!
- Disconnect the plug before performing any cleaning, maintenance or repair operation. Always
wear suitable clothing and working gloves.
- When the machine or part of it is lifted to carry out maintenance operations, always remember
to use suitable fixing tools such as holders and safety locks.
- When carrying out maintenance operations and/or when the machine is tilted without safety
locks or supports, never leave it unguarded in places where inexperienced people and children
could have easy access to it.
- Protect the environment: carefully dispose of used oils, petrol and any other pollutant product!
- Effective maintenance and correct lubrication help to keep the machine fully efficient.
ENGINE
For the lubrication intervals and procedure follow the directions given in the engine manual; it is in any
case indispensable to change the oil and the filter after the first 8 working hours and then every
100 hours. Use SAE 30 (API SJ) oil, quantity 1.9 litres. When you change the engine oil, it is necessary
to change also the oil filter (fig. 4, ref. B). To drain the oil out of the engine, open the lid on the left side of
the engine (fig. 4, ref. A). Pour in the oil through the lid (fig. 4, ref. A). The first precaution to be taken is
that the engine is maintained correctly with a clean air filter and the engine oil up to the level. Keep the
engine compartment, the muffler area and the collectors clean. Use a vacuum cleaner if possible. Check the
air filter (fig. 4, ref. D) every 8 hours or even more frequently in dusty conditions. In order not to reduce
the air needed to cool the engine, the grid on the upper part of the engine (fig. 4, ref. C) must always be
kept clean.
HYDRAULIC TRANSMISSIONS
Check the level in the reservoir with cold engines (fig. 5, ref. A). If more oil is needed, add engine oil
20W50 (total quantity: 4.5 litres). Carry out this control periodically. Caution! Change the oil in the
transmissions the first time after 40 hours and then every 200 hours or at least once a year.
The oil must be changed before the 200 hours if:
- the oil is black;
- the oil has a whitish colour (it is contaminated with water);
- there are black coloured residues (partial oil deterioration).
To remove the oil remove the filter (fig. 10, ref. A). Then install the new filter and pour in oil from the
balance reservoir (fig. 5, ref. A). 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; pay attention to the filtration level.
Always keep the hydraulic transmissions housing clean to guarantee that the oil is cooled by the
ventilation fins. If they are damaged, they have to be replaced.
GREASE LUBRICATION POINTS
Find the lubrication points following the scheme (fig. 2 no. 3). Every 40 hours grease the blade hubs, the
feed levers, the cutting deck lifting parallelogram, the pin connected to 2 points joint of the cutting deck,
the stabilizing cylinder ball-joints.
MACHINE STABILIZING DEVICE
The FX 20 has got a device that improves the machine's manoeuvrability on slopes. A oildynamic
cylinder (fig. 11) on the lower side of the frame intervenes when the rear wheel of the machine is slightly
lifted from the ground and blocks it. The oildynamic cylinder is controlled by a pendulum (fig. 6, ref. B)
that detects the slope. In this way, you have an optimum traction uphill and a remarkable stability of the
machine's rear part downhill.
Periodically check the oil level in the device (fig. 6, ref. A) and grease the oildynamic cylinder ball-joints.
Never fill the oil reservoir completely to avoid spillage. The perfect level is the half of the oil reservoir
capacity. Only use hydraulic oil OSO 10.
