f. Use the roller control lever to start the
rollers and gather the bag.
12.
Unloading Speed:
Hydraulic power is used to drive the bag rollers
and wheels. Use the flow divider to set and
control the speed of the movement into the
bag. The system is designed so the bag rollers
and tires drive together. Move slowly to allow
the grain or material to be picked up evenly.
9.
Stopping:
a.
Stop the movement of the extractor.
• Depress the wheel drive pop valve to
stop the wheels.
• Place roller drive lever in neutral.
b. Run until the pick-up assembly is empty.
c. Run until the discharge auger is empty.
d. Slow engine RPM to low idle.
e. Place hydraulic circuit and PTO in neutral
and stop engine.
10.
Emergency Stopping:
Although all the augers should be emptied be-
fore shutting down, in an emergency situation
shut down all power and power units immedi-
ately. Correct the emergency before resuming
work.
11.
Restarting (Unit Full):
When the machine is shut down inadvertently
or for an emergency, the augers and pick-up
assembly will still be full of grain or material.
When restarting, the starting loads will be
higher than normal. When restarting, follow
this procedure:
a.
Start the tractor and place the hydraulic
lever in detent.
b. Use the tractor to back the extractor 1 foot
(60 cm) from the grain in the bag. This will
allow the grain to empty from the pick-up
assembly.
c. Set the engine RPM to low idle.
d. Engage the PTO to start the unloading au-
gers and empty the unloading system.
e. Increase engine speed to 3/4 throttle posi-
tion and completely empty the augers.
NOTE
Reverse gathering roller then move
tractor ahead a little to reduce the
amount of residual material being
gathered. Do not drive ahead very
much to minimize the chance of
tearing the plastic bag.

NOTE
Slow the speed of forward motion to
reduce the load on the system.
