1. Unlatch boom transport clamp, flip up the
boom lock and swing boom back until it
clears the transport step.
2. Remove cover from vertical boom joint.
3. Set speed control at rear of control panel
between 1 and 2 to raise boom.
4. Use hydraulic boom lever (Up to raise,
down to lower). Carefully raise boom high
enough to allow cyclone assembly (at end
of boom) to swivel into position.
5. S
ecure cyclone into position, using
overcenter clamp.
6. Now lift boom all the way into working
position.
7. Secure boom with Over Centre Clamp.
8. Attach
suction line to the receiver tank
intake coupler. Close camlock couplers.
WARNING

when moving the boom. Electrocution can occur without
direct contact.
11
Operation - 6644 Grain Vac
Airlock Rotation
WARNING
Do not run the airlock in the reverse direction. Damage may
occur to the hydraulic motor.
For Best Performance:
1. Working area should be reasonably level
and dry.
2. The Farm King Grain Vac should be located
so the intake line is as straight and as short
as possible.
3. When using the Farm King Grain Vac to
load trucks, make sure there is adequate
room for the receiving vehicle to get under
the discharge cyclone.
Check the rotation of the airlock. Coupler
should turn as indicated by arrow.
Breaking In
Your machine has been operated for a short time at the factory to assure good performance. It can
however not be considered broken in. It normally takes 5 to 10 hours of operation for all parts to
be polished by the grain stream and for the machine to come up to full capacity.
We recommend the following checks during the break in period:
After operating for 1/2 hour
1. Check for overheated bearing. Lubricate or adjust as required*.
2. Check for oil leaks. Tighten or replace part and oil as required*
3. Retorque all hardware - Wheel bolts and fasteners.
4. Check belt tension and adjust as required*.
WARNING
High pressure fluids can penetrate the skin and cause
infection and toxic reaction.
5. C
heck the oil levels in the blower reservoirs. If low, add oil as required. Check for leaks and
correct if problem persists*.
* Check maintenance section for proper procedures. (Also see page 26 for hydraulic safety)
12
Operation - 6644 Grain Vac
After operating for 2 to 10 hours
1. Perform the same checks and inspections as done at 1/2 hour.
2. After the 10 hour inspection, go to normal service and maintenance procedures.
Set Airlock Speed
Material
Airlock Speed (RPM)
For maximum performance adjust speed most
suitable for material moved.
Barley
50 - 60
Canola
45 - 60
Material consistency varies widely in the
field. Airlock speed is also affected by suction
and discharge length. To obtain maximum
performance, try different airlock speed, using
above guide.
Corn
45 - 60
Flax
35 - 55
Wheat
45 - 60
Oats
45 - 60
A rule of thumb is the larger and heavier the
kernel, the faster the airlock should turn.
Tip - with light oats, or other light grains, slow
PTO speed down to 900 or 950 RPM.
Adjusting Speed
Using a stop watch, the airlock can be set by
counting the number of turns the coupler
makes. Coupler is visible through the three
slots in the deck of the machine (photo right).
One turn per second equals 60 RPM.
Adjust airlock RPM by moving the airlock speed
lever on your control panel towards
# 10 to increase speed, toward # 1 to slow
down. Move lever slowly, a small movement
will make a significant change in airlock speed.
13
Operation - 6644 Grain Vac
Short Distance Transfer
Insert bin nozzle.
Connect hose from receiver intake to bin
nozzle. Set the air slide on the full bin nozzle
all the way open and push the nozzle into the
material to be moved.
WARNING
Airslide (Full bin nozzle)
Do not cover airslide with grain.
The line of the grain can be horizontal, angled
or vertical depending on conditions.
Adjust the airslide on the full bin nozzle so
that the material moves across the sight glass
window of the receiver tank to approximately
half way (no more than 2/3) up the window. If
the machine starts to surge, slowly open slide
till surging stops.
Sight
Glass
NOTE: Should the material stop moving and completely cover the sight glass window in the
receiver tank, the machine will quickly plug. Immediately open the air slide fully, on the full bin
nozzle, to allow the machine to clear itself. Remove the nozzle from the grain and forward and
reverse the airlock several times to empty the tank. Then ensure the airlock is turning counter
clockwise and resume operation as normal. Otherwise follow the next 6 steps:
IMPORTANT: If the machine still does not clear
itself do the following:
• Stop machine by slowly reducing engine
RPM to an idle, then disengage PTO
clutch. Remove dust pail which will allow
any material in the bottom of Blower
Protection Cyclone (BPS) to run out.
• Remove nozzle from grain source
• Start the machine and allow the Receiver
tank to empty itself. Then stop machine
again
• Remove the top on the BPS and clean out
any material in the top of the cyclone and
in the pipe between the receiver tank and
the BPS.
• Replace the Dust pail and the Top on the
BPS.
• Start machine, (RECHECK AIRLOCK
SPEED, page 14) and reset the air slide as
per start up instructions.
NOTE: Airlock should not turn faster than
65 RPM or slower than 30 RPM.

Operation - 6644 Grain Vac
Long Distance Transfer
WARNING
Do not use P.V.C. or other plastic tubing for long distance
application. The build-up of static electricity could lead to
an explosion.
Auxiliary airslide. Located on the airline
between the receiver tank and the air pump.
If discharge length is more than 40 ft. (12 m)
or if blower gets too hot to the touch, open the
airslide approximately 1/4" - 1/2" (6 - 12 mm)
for every 100 ft. (30 m) discharge. Open further
if blower still gets hot.
Opening the airslide too far will affect capacity
as adversely as not opening it at all.
Auxiliary
Airslide
Top Loading (push only)
Feed grain below opening
to second cyclone
For top loading, remove top cover of large
cyclone. To avoid feedback be sure grain enters
below opening to BPS (smaller) cyclone.
Long Distance Suction
For sucking grain more than thirty feet, use
straight piping where possible!
Remember: The straighter the suction line the
greater the capacity of the grain vac.
Clean-up
When the machine needs not to be at full
capacity, e.g. when cleaning bins, the engine
can be throttled down.
Steel Flex Hose
The rougher walls of the steel flex hose and the
poly intake hose provide more resistance than
smooth pipe. Capacity may be lowered by 20%
to 40% compared to straight piping.
Use Poly hose for clean-up only.
For regular cleanup use a combination of steel
flex line, straight piping and poly hose. This
will give you the needed flexibility to easily get
into corners and around obstructions without
sacrificing too much capacity.
Poly
Intake Hose
NOTE: Do not dent, stretch or overbend steel
flex line excessively.
Do not store poly hose in sunshine, avoid
sharp obstructions that could cut or puncture
the hose.
15
Operation - 6644 Grain Vac
Seed Drill Clean Out
When using the seed drill clean out kit, operate
the engine at idle only to reduce suction
air flow. The receiver tank can be used as a
holding tank by stopping the airlock until the
seed can be discharged into a truck or storage
Cleanup of Spills and Ground Stored Grain
Multiple Bins (Parallel)
Extreme caution should be exercised when
cleaning spills or grain stored on dirt. Sand
and dirt may cause excessive wear to blower,
and life expectancy of the unit can be reduced
significantly.
Filling Bins and Temporary Storage
Rear discharge option required.
When discharging into bins, remove the airlock
discharge elbow and couple the machine to
stationary or movable piping.
For best performance, review recommended
installation schematics. Use OEM parts
to insure good sealing and maximum
performance.

caution
BPS
(Blower Protection System)
The air which is sucked from the receiver tank
and drawn toward the air-pump contains dust
which is harmful to the pump. This dust is
trapped by the BPS system and collected in
the dust canister. The amount of dust collected
depends on the amount of dust and fines in the
grain being moved.
Remove and empty dust canister regularly.
Do not allow to overfill. When canister is three
quarters full it should be considered full!
Dust Canister
NOTE:
If machine is allowed to overfill (plug):
• R
emove screen on top of BPS and clean if
required and reinstall.
• Empty canister and also allow any grain
which may have accumulated in BPS to
run out.
BPS Lid
Refer to unplugging instructions

Troubleshooting - 6644 Grain Vac
Troubleshooting
The heart and lungs of the Grain Vac are the airlock and the blower (air pump). Both components
must be operating at their recommended speed to obtain maximum efficiency from the machine.
The blower is driven by a belt and pulley system from the drive system attached to the engine. The
airlock is driven by a hydraulic motor that is attached to the diesel engine.
If you encounter a problem that is difficult to solve, even after having read through this trouble
shooting section, please call your local dealer or the factory. Before you call, please have this
Operators Manual and the serial numbers from your Grain Vac ready.
In North America call (204) 822-4467

Storage - 6644 Grain Vac
Storage
Prior to storage we recommend that you
thoroughly inspect your Grain Vac.
1. Replace any worn or damaged
components.
2. W
ash and clean the machine. After
cleaning, run machine at low idle for 2-3
minutes to dry the internal components.
Inject
Cleaning
Agent
Here
3. W
hile machine is running at an idle, open
the cleaning port and inject a cleaning
agent such as WD40 for 45 - 60 seconds.
This will coat the inside of the air pump to
help prevent rusting.
4. L
ubricate all grease points. Make sure
all grease cavities have been filled with
grease to remove any water residue.
5. R
etract and stow all components and
accessories and install cover over the
boom pivot. (Keeps out dirt and small
animals).
6. Inspect all hydraulic hoses, couplers,
fittings and lines. Tighten any loose fittings.
Replace any hose that is badly cut, nicked,
abraded or is separating from the fitting.
7. Inspect, clean or empty the BPS.
8. Check the fluid level in the air pump oil
reservoirs. Add oil as required.
9. Touch up all paint nicks and scratches to
help prevent rusting.
10. For storage, select an area which is dry and
level. Make sure unit is firmly blocked and
will not tip or sink into a soft area. Place a
plank under jack for added support.
NOTE: Reference the Cummins Diesel Manual, Twin Disc Clutch Manual and Dexter Manual for
proper storage instructions.
