Cups cleaning
Clean the moving parts of the drilling cups to remove any product residues so that the cups can move freely.
Tyres check
Check the tyres for wear and if they feature tears or signs
of ageing, they must be replaced.
Check tyres pressure and restore if necessary (see "Speci-
fications").
Cleaning the work vehicle
Clean the work vehicle with a high-pressure water jet
and, if necessary, with approved detergents.
The liquid used for washing could be hazardous for the
environment due to the presence of pollutants such as
detergents, oils, etc., therefore do not simply dump the
Troubleshooting
The following list contains a number of common problems that may arise during work, together with the ways to
solve them.
Problem
The seedling planted is too close to
the surface or too deep
The hole made in the plastic mulch
by the drilling cup is too long
The soil has not been properly
compacted on top of the seedlings
There is soil building up in front of
the resting skid
The plastic mulch is being dama-
ged
English language
MAINTENANCE INFORMATION
The pressure must be checked with the weight of the
work vehicle entirely on the ground and with nothing
and nobody on the work vehicle.
wastewater; dispose of it in suitable areas equipped with
separation devices for the pollutants.
Dry with compressed air and lubricate the components
shown (see "Lubrication diagram").
Likely cause
Incorrect planting depth
Incorrect transmission ratios for
the soil type
Packing wheels not set correctly
Transplanting unit is applying too
much force to the ground
Transplanting unit is applying too
much force to the mulch sheet

Solution
Make the relative adjustment (see
"Adjusting the planting depth")
Select the correct ratio (see "Plant spa-
cing range") and replace the pinion (see
"Replacing the pinion")
Adjust the packing wheels (see "Adju-
sting the packing wheels")
Adjust the force applied to the ground
by the unit (see "Adjusting the planting
force")
Adjust the force applied to the plastic
mulch by the unit (see "Adjusting the
planting force")
