MACHINE WASHING
To avoid sugar deposits and harvesting equipment
clogging and to preserve the harvesting quality, the
machine must be washed once or more times a day,
especially after its utilization.
The tractor unit should be cleaned with the engine at
a standstill, but for proper cleaning of the harvester
unit it is necessary to operate the norias, conveyors
and extractor fans with the machine in a permanent
location.
This is anyway a departure from the gen-
eral safety requirements specified in the Oper-
ator’s manual.
This operation requires thus a special care and the
absolute compliance with the following precautions:
S
first of all, this operation must be made by a
single operator, skilled in the control of this
machine.
S
The machine should be at a standstill , in-
side a suitable washing area, if possible as-
phalted and levelled, by at least 5x8 m, with
a water draining system, complying with the
regulations as for environmental preserva-
tion.
The washing area should be equipped as follows:
S
a hose having a minimum diameter by 35
mm, long enough for cleaning the machine
all around;
S
a sufficient water flow to get a 2--m water jet,
or a motor--pump unit with high capacity, with
a water reserve of 3--4 m
3
;
S
an adjustable nozzle to direct the water jet to
about 5 m;
S
a ladder about 3.5--m high and a hook
about 0.7--m long.
NOTE: the use of a high pressure cleaning machine
is definitely not recommended.
MACHINE ARRANGEMENT FOR WASHING
AT THE END OF THE CAMPAIGN
Before emptying the last hoppers, stop the thermal
engine.
-- Alight from the driver’s seat, gain access to the
inside of the harvester and cause any build--up of
crop around the shaker plates and on the rear
frame to fall into the buckets.
-- Move all the machine round and, starting from
below, remove all the accumulated dirt or scrap
material.
-- Climb onto the driver’s seat and start up the en-
gine, the extractor fans and the conveyors. Place
the norias in the cleaning position. Run the en-
gine for 10 seconds, then empty the hoppers.
