IMPORTANT
The operator should become familiarized with machine controls before attempting actual operation. Keep unit in
good working condition. Any modification could cause malfunctioning, potentially dangerous situations, or reduced
machine durability.
03
In order to obtain maximum performance from your grain bag unloader, we recommend you keep
the owner's manual in a handy place for quick consultation. Read the manual carefully before
attempting to unload grain from bags and pay special attention to operating and maintenance
instructions.
Safety precautions
For the operator
Before transporting the grain unloader, verify that:
a) The tow bar pin is properly secured
b) Check tire pressure
c) Check that wheel bolts are properly tightened
d) Attach safety chains between machine's tow bar and
tractor drawbar for added security on the road
Most accidents are caused by human error. Follow all safety procedures.
Make sure all people are safely positioned before starting tractor's engine and engaging
the PTO.
Keep unloader clean and sheltered when not in use. This diminishes risk of deterioration
and eventual failure.
Keep a fire extinguisher handy.
Decals with safety indications and warnings should be strictly heeded, kept in good
condition and replaced if necessary.
When towing the machine, drive with the utmost caution on public roads.
Keep hands, feet and clothing well away from moving parts.
Stop the tractor's engine before attempting a hands-on task on the unloader.

PTO stub
Fig.1
The tractor used with the E6910 unloader
should have no less than 60 HP.
Hydraulic circuit can be either open loop or
closed loop.
The PTO drive shaft should not exceed a 360
millimeter (14”) length, measured from end of
PTO stub shaft to drawbar hitch pin (Fig. 1) This
is to ensure adequate torque transference
between the two sections of the drive shaft.
A 12V electric hoist is used to raise and place
bag in position on the tunnel hood, so the tractor's
battery should provide that voltage.
Hitch pin “A” should be 30 to 32 mm. (1 3/16” to 1 1/4”) in
diameter and have its corresponding retaining clip “B” (Fig. 2).
A spacer should be placed between hitch tongue and drawbar
to prevent vertical rocking motion.

CAUTION
After connecting the hoses, check that they are not left so short that the bagger cannot maneuver without pulling at
them, nor too long that there is risk of them snagging a machine part.
Before connecting hoses to tractor: stop tractor engine
and depressurize hydraulic circuit by moving control lever in
both directions. Remove female plugs (Fig. 3, “B”) and wipe
clean coupling ends before connecting.
Before disconnecting hoses from tractor: stop tractor
engine and depressurize hydraulic circuit by moving control
lever in both directions. Pull out quick connect couplings and
cover ends with plugs.
The hydraulic cylinder is used to set the machine's inclination angle and working height. Hoses connect to tractor
hydraulic system through 1/2” NPT quick couplings (Fig. 3, “A”).

DANGER
A drive shaft connected to a live PTO that comes loose at the unloader's end will flail around uncontrollably, posing a
mortal danger to operator and bystanders, and can badly damage equipment at the very least. To avoid this possibility
ensure that:
a) Enough length of square shaft is inserted in adjoining female section
b) Quick release yokes are securely locked to splined stubs on tractor and bagger
c) Regular maintenance is carried out and U-joints are replaced if necessary
CAUTION
The PTO drive shaft demands that the operator be attentive and use maximum caution around it.
Make sure that protection shieds installed on tractor and shaft do not interfere with each other or with normal shaft
movement during work. Verify there is no excessive angle disparity between connection points: drive shaft should be
as horizontal as possible.
This maximum allowable length should not be exceeded because torsion effort could damage the shaft, or even worse, the
sections could come loose.
Also check that drive shaft is not left so short that adjoining sections could make contact. Apply grease to sliding parts.
When connecting yokes to tractor and unloader, ensure that they lock properly.
The protection shields have chains attached to their ends so that they can be secured and be
prevented from rotating simultaneously with drive shaft. Check that they turn freely before chaining them down.
Disassemble shaft into its male and female component halves.
With unloader hitched to tractor and square bar telescoping section
(male half) connected to PTO, place round tube section (female half)
alongside and verify that there are at least 400 mm. (16”) of square
bar that will insert (Fig. 4).
Check maximum and minimum lengths of shaft when open and closed.
Read following instructions to adjust length:
PTO drive shaft Make sure that the correct extremity (i.e., the square bar) of the drive shaft is connected to the tractor's PTO. This is
clearly indicated on the shaft itself.

Ground conditions were evaluated before bagging the grain. If terrain was not previously prepared it can be loose. The wheels
could hit potholes under the bag and tilt to one side.In case the ground is loose, machine height can be increased with
hydraulic cylinder. If there are potholes, they can be filled with soil or covered with elements such as bricks or planks as the
machine advances and lifts the bag off the ground, leaving the holes visible.

At no time during the unloading operation should anyone, except the operator standing at the hydraulic
controls, approach unloader or bag, and that includes both tractor and truck drivers. Onlookers should keep a
safe distance. And never allow anyone to lean against the bag: augers are turning inside.
Haul the machine to where extraction will take
place. When transporting the machine, the
discharge auger must always lie horizontal over
its support stand (Fig. 5) to prevent damage.
The hydraulic cylinder that determines height
clearance must be raised a to its maximum
position to prevent the cross augers from making
contact with the ground. The cylinder shaft must
be fitted with the aluminum stops provided so
that the weight of the machine rests upon them
(Fig. 6).
Before unhitching the unloader, place the front
located screwjack in vertical position (Figs. 7 &
8).

Once the machine rests on the screw jack, hitch it to the tractor drawbar (Fig. 9). Return the
screwjack to its horizontal stow position (Fig. 7).
Connect the hydraulic hoses to the tractor's hydraulic system (Fig. 10). Make sure hydraulic
quick couplings are well-matched with tractor hydaulic system, as incompatible fittings can
restrict flow and cause an oil temperature increase that can damage components.
Lower the drive shaft which is in transport
position (Fig. 11) and connect to tractor PTO
(Fig. 12).
Check that the drive shaft plastic protection
shields can turn freely and secure the chains
at both ends to fixed points on the machine.

Remove the short cross auger extension from its transport position (Fig. 13) and attach it to the end of the main auger shaft. Then use pins to
mount the corresponding protection grid (Fig. 14).
To configure the machine as a 10' bag unloader instead of a 9' bag unloader – the unloader is set up as a 9' machine in factory because
transport has to be done under a 9' configuration – the protection grid must be moved to its outermost position (Fig. 15), the intermediate grid
removed from the frame (Fig. 16) and installed in the open section that remains (Fig. 17). Finally, mount the long cross auger extension on the
shaft (Fig. 18).
All hydraulic functions are controlled from a central command
station. On the upper section is a knob (Fig. 19) that is turned
completely clockwise or completely anti-clockwise depending
on the function to be performed. See detailed instructions in the
following box

Fig.20 Fig.21
Three levers on the valve cluster regulate hydraulic flow, as depicted in the diagram below. First and second levers “A” & “B” (which
operate the machine's hydraulic cylinders) are mounted on valve sections to the left of the control knob, while third lever “C” (which drives
the roller) is mounted to the right of the control knob. This knob operates the flow control valve.
The diagram shows the operational speeds that turning the control knob clockwise or anticlockwise, in combination with each specific lever,
has on the different hydraulic circuits. Operating speed, dependant on hydraulic flow, is all important when it comes to the roller.
Roller speed on initiating extraction should start in the low revs position and should then be increased as necessary. The knob should
initially be turned completely clockwise, in which position the roller will not move at all when lever “C” is actuated, and then progressively be
turned counterclockwise until the desired rpm are attained (Fig.20).
Conversely, if levers “A” or “B” are actuated, hydraulic flow (i.e. operating speed) increases when the knob is turned clockwise. If the
cylinders do not move at all or do so very slowly, the reason is that the knob is completely, or almost completely, turned
counterclockwise.(Fig.21).
The next sections show the use of hydraulic levers “A”, “B” and “C”.

Machine Clearance
First step in preparing for work is raising the discharge auger.
With the tractor's hydraulics turned on, move lever "A" to
upward position (Fig. 22). This will raise the auger tube. Before doing
that, remove any grain that may have accumulated on the connecting
faces as this may prevent correct closure and cause losses through
the resulting gap.
When auger is fully extended, move back the lever to its mid
position (neutral). Once the unloader has finished working and
is to be towed away, the sequence is reversed and the tube is
lowered onto its support bracket by moving lever "A" downward.
Next, second lever “B” is used to regulate working height (i.e.,
clearance of the sweep augers to the ground). To raise the unloader,
the lever is moved to its top position (Fig. 23). The object of height
regulation is to set minimum clearance possible without compromising
bag integrity which can be occur if the augers run into the ground
because of potholes.
The machine cannot be raised during operation. The only way to do it
is to first extricate the sweep augers from the mass of grain and only
then proceed to modify height.

Stops provided come in 3 sizes: 58mm,
40mm and 30mm. Once a combination
of stops has been selected and placed
around the cylinder rod, lever “B” is
pulled down so that the9 weight of the
unloader comes to rest upon the stops
(Fig. 24). At this point the lever is
returned to its neutral position.
The cylinder's bottom located screw
(Fig. 25) allows further height adjustment.
As a practical tip, it is recommended that
the cross auger outer protection rings be
at a height of 8 or 10 cm (3” or 4”) from the
ground (Fig. 26)
The unloader should not be raised or lowered with the hydraulic cylinder if the augers are deep within the grain mass, as
this could place undue strain on some components. The correct procedure is to release a few feet of plastic from
the roller by counter rotating it hydraulically, advance forward with tractor to extricate the sweep augers from the grain,
modify machine clearance with the hydraulic cylinder removing or adding stops as necessary, back the machine once
again into the bag to position the augers next to the grain, and reinitiate PTO and roller to continue unloading.
