Operation - 6644 Grain Vac

Boom Swivel

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. Secure 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

All bystanders should stay well clear of boom when raising or lowering it.

DANGER

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. Check 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

For maximum performance adjust speed most suitable for material moved.

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.

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.

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.

14

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.

Top Loading (push only)

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.

Auxiliary

Airslide

Feed grain below opening to second cyclone

Clean-up

When the machine needs not to be at full capacity, e.g. when cleaning bins, the engine can be throttled down.

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.

Steel Flex Hose

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

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.

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!

NOTE:

If machine is allowed to overfill (plug):

• Remove 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.

Refer to unplugging instructions under Operation.

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

Problem

Low capacity

Excessive grain damage.

Cause

Belts are slipping.

Airlock runs too fast.

Solution

Tighten belts.

Slow down airlock speed until grain builds up to the level of inspection door.

Adjust air intake.

Improper air intake.

Improper use of nozzle.

Air leaks - Intake.

Air leaks - Machine.

Improper piping.

Use full bin nozzle for larger piles and full bins. Use cleanup nozzle with flair for cleanup only. Do not submerge airslide in grain.

Check for worn coupler levers or missing coupler gaskets.

Check BPS, receiver section, and airlock gaskets.

Check pressure and vacuum relief valve.

Check clamps on airline between receiver tank and BPS and between BPS and blower.

Keep suction lines as short as possible.

Minimize bends.

Use straight length of pipe wherever possible.

Use the poly hose for clean up only!

Airlock tip clearance high.

Airlock end plate clearance

Adjust airlock tips.

If rotor to end plate clearance is more than 0.015", consult the dealer or factory.

Too much air intake.

Adjust air intake nozzle.

Blower running too fast. Throttle down engine.

Damaged tubing or flexline.

Repair or replace.

Insufficient grain supply. Reposition nozzle.

Troubleshooting - 6644 Grain Vac

Problem

Pulsation

BPS plugs

Airlock not turning at all.

Cause Solution

Insufficient air at intake. Open slide until grain flow becomes even.

Airlock turning too fast.

Improper piping.

Adjust airlock speed until grain is at level of the inspection door.

Replace steel flex or poly hose with rigid tubing wherever possible.

Suction line too small.

Use proper line size.

Engine running too slow. Increase engine RPM to recommended speed.

Belts are slipping.

Excessive airlock tip clearance.

Tighten belt.

Adjust airlock tips.

Increase airlock speed until grain is at the proper level on the inspection window.

Decrease airlock speed until the grain is at the proper level on the inspection door.

Check for and remove obstruction in airlock

Reset flow control.

Obstruction in airlock.

Shift Forward/Reverse lever from FORWARD to REVERSE and back to FORWARD. Repeat if obstruction does not clear up. If obstruction does not clear up, shut off engine, open inspection door and remove cause of obstruction.

Hydraulic oil heating up excessively.

Low oil level.

Add oil.

Excessive wear on air lines.

Improper piping.

Too much air flow.

Minimize bends.

Adjust airslides and airlock speed.

Insufficient grain supply. Reposition intake nozzle. Open grain supply doors.

Excessive engine speed. Operate at proper recommended engine speed.

NOTE: Also reference the Cummins Diesel Manual, Twin Disc Clutch Manual and Dexter Manual for proper troubleshooting instructions.

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. Wash and clean the machine. After cleaning, run machine at low idle for 2-3 minutes to dry the internal components.

3. While 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. Lubricate all grease points. Make sure all grease cavities have been filled with grease to remove any water residue.

5. Retract 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.
