IMPROPER USE
By improper use we mean:
-
using the machines for operations they were not designed for or for usages that do not appear in the chapter
“Machine’s Description and End Use” of this manual;
-
use of the machine by people under the age of 18, and/or people not trained to use this kind of equipment.
INCORRECT USE
By incorrect use we mean using the machines without respecting the instructions of the manual.
Not respecting these instructions could risk injury to the operator or third parties, and cause damage to the machine.
Incorrect use can thus mean:
-
incorrect installation and/or use of the components or optional accessories.
-
incorrect preparation of the machine.
-
not using the manufacturer’s spare parts.
-
repairs by non-authorized people.
-
maintenance by non-qualified people.
-
uses the machine is not designed for (see above), lack of maintenance.
WARNING: the manufacturer cannot be held responsible for any injury to people, animals or damages to
things resulting from improper or irresponsible use, as mentioned above.
METHOD OF USE
Users
Users are divided into two categories:
- OPERATOR: a person without technical knowledge but trained to use the machine and carry out simple
maintenance and adjustments.
- QUALIFIED TECHNICIAN: a person who works on behalf of the manufacturer and/or retailer and can carry out
complex maintenance and repairs.
Indications before using
Before starting the machine, you should read this manual carefully.
Check that everything has been installed and checked by a qualified technician.
Send away everybody from the working area before starting work, than proceed slowly checking your machine.
Make sure there are no people standing in the vicinity of the machine and start up the power takeoff slowly until it
reaches a maximum of 400 rpm within the 540 rpm range.
Check that everything is functioning properly and that there are no vibrations.
Use a speed of advancement that does not exceed 3 Km/hr.
The cardan shaft’s actual speed of rotation should remain between 280 and 400 rpm to obtain optimal results.
Follow a straight line while moving forward and try to insert the outer extremity of the machine between the plant
stocks without going beyond 5 cm of the rows’ centerline.
When the machine is resting on its skids, adjust its working depth by regulating the threaded arm of the third point on
the tractor hoister.
Use the respective hydraulic jack to tilt the rotor head to the most appropriate angle in order to obtain an even working
depth.
Use the manual chord or electric button of the safety device to operate the equipment when plant stocks are bent or
feeble, since these may cause the feeler pin to perform inefficiently.
Work the same row on both sides; if it is on a slope, preferably work the side that is positioned uphill first.
The equipment should not absorb more than 25 hp from the power takeoff in normal working conditions.
If it is used with tractors that exceed 35 hp, immediately adjust the various settings and operating procedures before
the equipment show signs of excessive strain.
The machine was designed to operate at a maximum working depth of 10 cm. Increasing the depth does not improve
the weeding process; it would produce greater power absorption, ultimately causing the pieces to wear out
prematurely.
CORRECT USAGE
: keep in mind that each time the machine operates in close proximity to plant stocks the cardan
shaft retracts and subsequently extends enduring torque strain.
While working, maintain the joints at the same angles and within the following parameters: max 25° for continuous
work, and max 45° for intermittent work (with up to 5 minutes of continuous work).
The cardan shaft will encounter greater resistance when the soil is hard or coarse, and when the working depth and
shifting movements are greater.
In these cases, the shaft will require more power from the hydraulic system, which may cause it to overheat.
Detach the equipment if you intend to perform maneuvers that would require greater angles than those indicated.
