10. Check the vanes on the entry turbine for wear.
11. Check that no foreign objects have clogged the turbine.
12. Check the rotation of the duct inside the grass catcher.
13. Check that the blades disengage automatically when the grass catcher is full; to do this, turn the ignition key,
turn on the panel without starting the engine , engage the PTO blades (fig. 1 no. 2) and touch by hand the
vane fitted to the duct sensor (fig. 14). The PTO should now disengage.
14. Check the engine revs. (2800 rpm diesel engine).
15. Always mow with the engine at maximum revs; if the engine revs drop, slow down for a while, to allow the
engine to reach the right level again.
16. Check that the blades are fitted properly.
17. Check that the entry duct fits correctly and is aligned inside the turbine.
18. CAUTION! To make easier a comfortable driving, the feed pedals and the reverse pedals (fig. 1 n
°

are endowed with power steering assembled on a pump; during the work on a climb, press the pedal, without
stressing the engine.
19. The lawnmower FD 1500 is a cold hydrostatic machine, so it absorbs more power, after e few minutes the
efficiency will be optimal. We inform you that the changeable delivery pump and the hydrostatic engines are
of optimal quality and high efficiency: the minimal loss is 5%.
20. The emergency brake pedal (fig. 1 n
°
3) must be used only if there is a real emergency. Normally use the
feed pedals and the reverse pedal to stop the machine (fig. 1 n
°

2).
21. CAUTION! Do not travel during the transfers, if the cutting deck is high. Use the cutting deck hydraulic lifter
only to get over the obstacles: mount on pavements or on kerbs.
It is compulsory, instead, to travel on public streets with a type-tested machine, endowed with the lights
system, the plate and the cutting deck up.
MOWING POSITION
Use the 4 pins (fig. 11 n
°
12) to adjust the cutting height.
When working on terrain which is rough, has bumps or humps, it is best to use the deck in the highest cutting
position to avoid impact with the blade.
SLOPING GROUND
Steep ground should be tackled in an up-and-down movement, being very careful at direction changes that the
wheels uphill do not meet any obstacles (stones, branches, roots, etc.) which could cause loss of control over the
machine. If the drive wheels tend to slip, use the hydraulic control to raise the deck slightly so that more weight is
exerted on the drive wheels, therefore giving more traction.
Evaluate the various conditions and be careful in the presence of damp ground and wet grass because this could
cause the mower to slide. When going downhill, start off at a slow speed and avoid driving over dry or cut grass
because the wheels could lose their grip.
The differential gear locking (fig. 2 n
°
11) must be used only in special cases, for example: if during a strong
descent you want to reverse the direction of travel, to avoid the rear wheels skidding, or in case of load on motor
vehicle in reverse motion with the presence of ramps.
Normally do not engage the differential gear locking.
Do not run any risks, check carefully the ground and if you are not so safe, avoid the slopes and do not exceed
the speed-limits, which are imposed by your country laws and written also in this manual.
SAFETY DEVICE TRIGGERING
Always remember that the engine stops each time:
the operator gets up from the seat.
In addition, the engine will not start if:
–
the PTO reverser is engaged;
– the turbine reverser is engaged;
– there is no one seated at the controls;
– the feed pedals and the reverse pedal are not in the stop position;
– the basket is not completely lowered.
MAINTENANCE AND LUBRICATION
CAUTION!
Stop the engine, remove the ignition key, before carrying out any cleaning, maintenance or repairs. Always
wear suitable working clothes and safety gloves.
