GENERAL INFORMATION

3. General instructions for the operation and maintenance
Before starting off for work, be sure that the machine is correctly assembled and in good
operating condition.
The front transport arms must always be attached during transport.
While the front transport arms are attached, do not operate for any reason whatsoever the
hydraulic cylinders for opening the machine or lifting the rake wheels.
When the machine is in movement, make sure that the brake on the front wheels does not block
wheel movement. The wheels must always pivot freely.
When in operation, do not turn around at full speed.
On particularly uneven ground, do not operate with the machine in the fully-opened position
(close machine at least 3’ compared to the fully-opened position). In addition, operate at a
reduced speed.
lf it is noticed that the machine is not operating properly (rake wheels putting too much pressure
on the ground, front wheels braked, etc.) the problem must be corrected immediately to avoid
causing damage to the machine.
If machine maintenance work, repairs or adjustments must be done in the field, they should be
done at a spot where the ground is firm and level. Turn off the tractor and apply the parking
brake. Use the proper tools and wear suitable protection (safety goggles, work gloves, etc.).
If any maintenance work, repairs or adjustments are done which require that some parts be
removed and/or that screws, nuts, pins, etc. be loosened or removed, always make sure that
everything is reassembled or retightened as it had been prior to making repairs or adjustments.
Follow the schedule provided for maintenance.
By following these suggestions it will be possible to keep the machine operating safely and
efficiently, to the benefit of the user.
IMPORTANT
DURING EXTENDED PERIODS OF INACTIVITY IT IS NECESSARY TO CLOSE COMPLETELY
THE CYLINDERS. THIS MUST BE DONE IN SUCH A WAY AS TO PROTECT THE RODS
FROM WEATHER EFFECTS.
THE RODS PARTS REMAINING OUTSIDE THE CYLINDER PIPE ( WHATEVER REASONS
MAY BE ) MUST BE CAREFULLY PROTECTED WITH A GREASE LAYER.

ASSEMBLY INSTRUCTIONS

4. Assembly instructions
Assembly must be done carefully and accurately, for the safety of the person(s) doing the
assembling and to ensure proper machine operation.
Assembly should be done on a flat, solid surface, using the proper tools and wearing suitable
clothing, making sure that all people not involved in the assembly be kept at a safe distance.
Assemblers must provide suitable lifting mechanisms and supports for stabilizing the partially
assembled units, so as to prevent them from falling and causing damage or injury. The steps for
assembly are illustrated in following. Depending on the experience of the assemblers and the
tools available, it is not necessary that the instructions be followed in the exact order given here,
but the safety precautions described above must always be followed carefully and scrupulously.
IMPORTANT
These signs and symbols give information to the operator on how to make the best use of the
machine so as to prolong life, avoid damage, optimise work and, above all, to avoid injury to the
operator and anyone within range of the machine.
4.1 Warning signs
A) Before beginning operations, read the
instruction manual carefully.
B) Before doing any maintenance or repair work,
stop the machine at a suitable spot. Turn off the
tractor motor, apply the brake, remove the key
from the ignition and consult this manual.
