E. Adjustable Air Throttle and Vent
The Grain Vac comes equipped with a unique feature
that decreases the horsepower requirement of the
unit. It consists of an internal damper plate that senses
high airflow, and hence high horsepower situations
and moves into position to limit the condition.
The damper plate is controlled by an external spring.
The condition of this spring should be checked
visually occasionally and should be replaced if it
appears to be sprung or damaged.
The Air Throttle is normally set in the unpinned
position in which the spring controls the position of
the damper plate. This position is used for most
products.
1. If you experience the air throttle fluttering,
adjustment should be made. To correct this
problem simply tighten the adjusting bolt (see
Figure 11) until the flutter is removed.
2. If the throttle is not moving, check the assembly
for binding. Loosening the tension spring may
also be required.

3. To lower the Bin Snake assembly, raise the
assembly slightly, just enough to take the pressure
off of the latch handle.
4. Lift the latch handle open and then slide the Bin
Snake down to your desired position. Lock in
place with the latch handle.
Using the Optional Bin Snake
1. After you have reached the back of the bin with
the MaxFlo Nozzle, from within the bin, unlatch
the rubber retaining strap holding the Bin Snake
in transport and unfold it into the bin one section
at a time. As each section is unfolded, the hose
should be raised up and strapped under the Bin
Snake. When all the Bin Snake sections are
attached to the hose, you are ready to cleanup
the floor of the bin. Extra Bin Snake sections
are available to reach further into larger than
average bins.
2. Remove the last section of steel hose and the
Full Bin Nozzle. Attach the flexible rubber hose
and the Cleanup Shovel and proceed with final
cleanup.
3. Start cleaning at the back of the bin and work
your way forward, toward the door. Clean
directly in front of the door last. You can remove
sections of flexible steel hose as you get closer
to the door.
4. When bin clean up is complete, lower the Bin
Snake to it’s lowest position before lowering
the auger.
