Grillo FD 1500 2WD Uso Y Mantenimiento página 23

MACHINE WILL NOT KEEP THE STOP POSITION
If the machine does not stop or withdraws even if it has the pedals in the stop position, work on the pump (fig. 28).
This operation must be done in a authorized service centre.
ELECTRICAL CIRCUIT
The electrical circuit is protected by fuses which, if blown, cause the whole electrical circuit to cut out. These are located:
1) under the bodywork, opening the turbine check gate (fig. 1 n° 21). The general fuse is 70 A/h (fig. 29).
2) the fuse holder box, thanks to all its functions, is on the right of the driving seat, on the fairing (fig. 30).
Once the fault has been located and repaired, replace the blown fuse with one of the same rating.
Never replace a fuse with another of a different rating.
All the relays are inside the box (fig. 31), endowed with 2 connections to make the disassembly easier.
A security sensor detects if the basket is in working position (fig. 32), differently the turbine and the cutting deck
does not engage.
If the fault still persists even after having carried out the operation described above, contact the Authorised
Service Centre.
Never attempt to carry out complex repairs without having the necessary means and technical knowledge available.
AIR FILTER
Check the air filter every 4 hours or more frequently if the place where you use the machine is very dusty (fig. 8).
The air filter is endowed with a depression sensor, that signals on the dashboard that the filter is obstructed.
FINISHING WORK
Once mowing has been completed, disengage the blades and the turbine, take off the foot from the feed pedal
(fig. 1 n° 1 o n° 2), set the throttle lever to idling speed, lower the cutting deck on the ground, turn off the engine
by turning the key in the "0" position and the connect parking brake (fig. 1 n° 11).
CLEANING
Clean the deck, the entry ducts, the turbine and the basket. Do not wash the engine compartment with water
under pressure, use compressed air or a vacuum cleaner.
TOWING BAR
The towing bar is located in the rear part of the machine. You can tow compacting rollers and driven trailer max
weight 4 q in the plain.
STORAGE AND LACK OF USE FOR LONG PERIODS
Store the machine in a dry environment, sheltered from the elements and, if possible, covered up.
If the mower will not be used for a long period (more than one month), disconnect the red lead from the battery
and follow the directions given in the engine manual; in addition grease all the joints.
Check regularly that the battery voltage has not dropped below 12 Volts and if it does so, recharge it.
IMPLEMENTS
LIFTING HOOKS AND TRANSPORT
The lifting hooks (fig. 34) location permits that the machine with the mounted cutting deck is perfectly balanced if
it must be lifted up with the crane.
If the machine is carried with a camion or with a towed trailer, put the cutting deck in a low position, connect the
parking brake and tie it to the mean of transport through ropes, cables, or chains.
150 CM. GRASS SHREDDER
The grass shredder (fig. 41) is very useful for cleaning countryside with tall, wild grass. Allows the cut product to
be shredded making collection unnecessary.
It comes equipped as standard with "Y" shaped hoes, also suitable for shredding small pruned branches.
It can be fitted with grass blades to give a cutting quality equal to that of the lawnmower, or converted into scarifier
by changing the hoes with expulsion vanes.
Applied in the same way as the lawnmower, be careful to fit the universal joint onto the grooved shaft.
Check regularly the tension on the belts at the side of the grass shredder.
If the grass shredder vibrates, check the hoes.
