attachments are present. Claims must be ma e in writing to the agent within 8 ays of receipt.
The manufacturer warrants new machinery at the time of elivery to the original purchaser to be
free from efects in material an workmanship if properly set up an operate in accor ance
with this Operator's Manual.
The manufacturer un ertakes to repair or replace free of charge any etective part which shoul

GENERAL INFORMATION

3. General instructions for the operation and maintenance
Before starting off for work, be sure that the machine is correctly assemble an in goo
operating con ition.
The front transport arms must always be attache uring transport.
While the front transport arms are attache , o not operate for any reason whatsoever the
hy raulic cylin ers for opening the machine or lifting the rake wheels.
When the machine is in movement, make sure that the brake on the front wheels oes not block
wheel movement. The wheels must always pivot freely.
When in operation, o not turn aroun at full spee .
On particularly uneven groun , o not operate with the machine in the fully-opene position
(close machine at least 3’ compare to the fully-opene position). In a ition, operate at a
re uce spee .
lf it is notice that the machine is not operating properly (rake wheels putting too much pressure
on the groun , front wheels brake , etc.) the problem must be correcte imme iately to avoi
causing amage to the machine.
If machine maintenance work, repairs or a justments must be one in the fiel , they shoul be
one at a spot where the groun is firm an level. Turn off the tractor an apply the parking
brake. Use the proper tools an wear suitable protection (safety goggles, work gloves, etc.).
If any maintenance work, repairs or a justments are one which require that some parts be
remove an /or that screws, nuts, pins, etc. be loosene or remove , always make sure that
everything is reassemble or retightene as it ha been prior to making repairs or a justments.
Follow the sche ule provi e for maintenance.
By following these suggestions it will be possible to keep the machine operating safely an
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 one carefully an accurately, for the safety of the person(s) oing the
assembling an to ensure proper machine operation.
Assembly shoul be one on a flat, soli surface, using the proper tools an wearing suitable
clothing, making sure that all people not involve in the assembly be kept at a safe istance.
Assemblers must provi e suitable lifting mechanisms an supports for stabilizing the partially
assemble units, so as to prevent them from falling an causing amage or injury. The steps for
assembly are illustrate in following. Depen ing on the experience of the assemblers an the
tools available, it is not necessary that the instructions be followe in the exact or er given here,
but the safety precautions escribe above must always be followe carefully an scrupulously.
IMPORTANT
These signs an symbols give information to the operator on how to make the best use of the
machine so as to prolong life, avoi amage, optimise work an , above all, to avoi injury to the
operator an anyone within range of the machine.
4.1 Warning signs
A) Before beginning operations, rea the
instruction manual carefully.
B) Before oing 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 an consult this manual.

5. Assembly steps
In the steps for assembly we will use the terms "RH part" an "LH part". The istinction is
conventionally ma e looking at the machine from the rear. For the purpose of simplification, we
will illustrate machine assembly for one si e only; since the machine is symmetrical, each
operation must be one on both si es.
1. ATTENTION
Fit bushings 4 on proper seats of uprights 2 & 3. Attach the wheel supports 2 & 3 (LH - RH) to
the
cross member assembly 1
using pins 5, washers 6 & 7 an
screws 8. To i entify parts 2 & 3
(LH - RH) see the next step.
NOTE: measurement labels
(see next figure) must be rea
from the rear si e of the
machine.
In this step, you will use:
Item 4:
4 - bushings D 50 - 60 x 50
(D 2" - 2" 3/8 x 2")
Item 5:
2 - pins D 50 x 190
(D 2" x 7" 1/2)
Item 6:
2 - washers D 23 - 75 x 12
(D 29/32"- 3" x 1/2)
Item 7:

(7/8" x 2")
Item 9:
2 - grease nipples M 8
(5/16")

For correct assembly, the RH support 3 an the LH support 2 must lean in slightly towar s the
center of the machine. After assembly, they must have the measurements given (minimum
wi th). At this point, before moving on to next step, keep in min that the assembly is unstable
an therefore it is recommen e that extreme caution be use .
NOTE: For the win row wi th’s a justment see page 44.
