Maintenance And Lubrication - Grillo FD 1500 PRO 4WD Manuel D'utilisation

turn on the panel without starting the engine, engage the PTO switch (fig. 2 no. 8) and touch with a hand the
lever fitted on the duct sensor (fig. 14). The PTO should now disengage.
15) Check the engine revs. (max. 2400 rpm, max. 2600 rpm at no load).
16) 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.
17) Check that the blades are fitted properly.
18) Check that the cutting deck fits correctly and is aligned inside the loading accelerator.
19) CAUTION! For a comfortable driving, the feed and reverse gear pedals (fig. 1no. 1 and no.2) are fitted with
servo-control on the pump, during work on slopes press the pedal without straining the engine.
20) The lawnmower FD 1500 PRO 4WD is a hydrostatic machine, so it absorbs more power when cold, 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%.
21) The emergency brake pedal (fig. 1 no. 3) must be used only if there is a real emergency. Normally just release
the feed and the reverse pedals to stop the machine (fig. 1 no. 1 and no. 2).
22) CAUTION! Do not transfer the machine with lifted cutting deck. Use the cutting deck hydraulic lifter only to get
over obstacles, mount on pavements or on kerbs. It is compulsory, instead, to travel on public streets with a
type-approved machine, endowed with a lights system, a plate, with the cutting deck up and with an empty
grass catcher.
MOWING POSITIONS
Use the 4 pins (fig. 11 and fig. 12) to adjust the cutting height.
When working on rough terrain, with bumps or humps, it is best to use the deck in the highest cutting position to
avoid impact with the blade.
Attention! During the cut the deck lifting lever has to be in the «floating» position.
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 slightly raise the deck 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 locking (fig. 2 no. 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 locking.
Do not run any risks, check the ground carefully and if you do not feel safe, avoid strong slopes and do not exceed
the speed-limits, which are imposed by your country laws and written also in this manual (max. 18° or 32%).
SAFETY DEVICE TRIGGERING
Always remember that the engine stops each time when:
-
the operator gets up from the seat, if the parking brake has not been engaged and the blades and the turbine
have not been disengaged before.
In addition, the engine will not start if:
-
the PTO switch is engaged;
-
the turbine switch is engaged;
-
if there is no one seated on the driving seat, unless the parking brake has been applied and the blades have
been disengaged;
-
the feed pedals and the reverse pedal are not in the stop position;
-
the grass catcher is not completely lowered.
Attention! When the parking brake is applied, it is possible to leave the driving seat with the engine on, provided the
blades and the turbine are switched off.
CAUTION!
Stop the engine and remove the ignition key before carrying out any cleaning, maintenance or repairs.
Always wear suitable working clothes and safety gloves.
If you do the maintenance on the engine, keeping the basket up, engage the two red painted security locks on the
hydraulic cylinders (fig. 15). Never work on the engine if you have not engaged the locks.
LUBRICATION
Never dispose of used oil, petrol or any other type of pollutant in the environment!
Proper maintenance and correct lubrication help to keep the mower perfectly working.
