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.
05
WARNING:
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.
2) To the side of the machine, on the roller
cross beam, an array of three levers, a turn knob
and a pressure limiting valve control the
unloader's hydraulics. A decal attached next to
them (Fig. 1) shows each control's function.
First step in preparing for work is raising the
discharge auger. With the tractor's hydraulics
turned on, move the first lever to its upward
position (Fig. 2). This will raise the auger tube
slowly.
As soon as auger is fully extended, move back
the lever to its mid (neutral) position. Once the
unloader has finished working and is to be towed
away, the sequence is reversed and the tube is
lowered by moving down the lever.
The sequence ends once the upper half is resting
firmly upon its transport prop and the control lever
is returned to neutral position.
1) Hitch tractor to unloader, connect hoses to
the tractor's hydraulic circuit and connect drive
shaft to the tractor's power take-off.

NOTE:
A pressure limiting valve set to 850 PSI is provided as a safeguard against excessive pressure in the hydraulic circuit.
If this value is exceeded, oil will bypass the hydraulic motor and momentarily bring operation to a standstill.

3) Next, the second lever is used to regulate working
height (i.e., clearance of the sweep augers to the ground)
by means of a hydraulic cylinder. First, this center lever
should be moved to top position in order to raise the
unloader. To adjust for desired clearance, and the object
here is to set the sweep augers as close to the ground as
possible without scraping against it and compromising
bag integrity (see “General indications for efficient
operation” on page 26), a set of three clamp-on stops of
different size is provided.
Once a combination of stops or a single stop have
been selected and placed around the cylinder rod, the
control lever is pulled down (Fig. 3) so that the weight of
the unloader comes to rest upon the stops (Fig. 4). At this
point the lever is returned to its neutral position. The
height of the machine can be modified at any point, even
when the sweep augers are inside the bag.
IMPORTANT:
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.
7) Lower the support stand and reinsert pin
at the base (Fig. 8).
5) Remove the pin at the base of the support stand,
swing the stand upward and attach temporarily to main
beam with same pin (Fig. 5).
4) The third lever, used to control roller rotation,is
not used at this stage.
6) Pull back the
spring-loaded pin that holds the
roller assembly in place during
transport and swivel it 90º to
work position (Figs. 6 & 7).
