SAFETY
YOU are responsible for the SAFE operation
and maintenance of your Walinga Ultra-Vac®.
YOU must ensure that you and anyone else
who is going to operate, maintain or work
around the Ultra-Vac® be familiar with the
operating and maintenance procedures and
related SAFETY information contained in this
manual. This manual will take you step-by-step
through your working day and alerts you to all
good safety practices that should be adhered to
while operating the Ultra-Vac®.
2.1
GENERAL SAFETY
1. Read and understand the
Operators Manual and all safety
signs before operating,
maintaining, adjusting or
unplugging the Ultra-Vac®.
2. Only trained competent persons
shall operate the Ultra-Vac®. An
untrained operator is not qualified
to operate the machine.
3. Have a first-aid kit available
for use should the need
arise and know how to use it.
Remember, YOU are the key to safety. Good
safety practices not only protect you but also
the people around you. Make these practices a
working part of your safety program. Be certain
that EVERYONE operating this equipment is
familiar with the recommended procedures and
follows all the safety precautions. Remember,
most accidents can be prevented. Do not risk
injury or death.
•
Ultra-Vac® owners must give operating
instructions to operators or employees
before allowing them to operate the
equipment, and at least annually thereafter.
•
The most important safety feature on this
equipment is a SAFE operator. It is the
operator’s responsibility to read and
understand ALL Safety and Operating
instructions in the manual and to follow
these. All accidents can be avoided.
•
•
Walinga feels that a person who has not
read, understood and been trained to
follow all operating and safety instructions
is not qualified to operate the equipment.
An untrained operator exposes himself and
bystanders to possible serious injury or
death.
Do not modify the equipment in any way.
Unauthorized modification may impair the
function and/or safety of the equipment and
affect the life of the machine.
Think SAFETY! Work SAFELY!
Have a fire extinguisher available
and know how to use it.
5. Do not allow riders.
6. Wear appropriate protective gear.
Remember to be an efficient operator. An
efficient operator is a very safe, cost
efficient and professional person.
•
•
4.
This list includes but is not
limited to:
- A hard hat
- Protective
shoes with slip
resistant soles
- Protective goggles
- Heavy Gloves
- Wet weather gear
- Hearing protection
7.
Before servicing, adjusting,
repairing or maintaining unit,
ensure that unit power source is
completely shut down and can
not start up.
8. Wear appropriate hearing
protection when operating for
long periods of time.
9. Know where overhead electrical
lines are located and stay away
from them. Electrocution can
occur without direct contact.
10. Review safety related items
annually with all personnel who
will be operating or maintaining
the Ultra-Vac®.
2.2 OPERATING SAFETY
1. Read and understand the Operator’s
Manual and all safety signs before using.
13. Wear appropriate ear protection when operating
or long periods of time.
2. Place all controls in neutral, stop the
engine, remove ignition key and wait for all
moving parts to stop before servicing,
adjusting, repairing or unplugging.
3. Do not operate when any guards are
damaged or removed. Install and secure
guards before starting.
4. Keep hands, feet, clothing and hair away
from all moving and/or rotating parts.
11. Do not place intake nozzle near feet when
standing on the top of grain.
5. Do not allow riders on the Ultra-Vac® or
towing vehicle during operation or
transporting.
12. Before applying pressure to the hydraulic
system, make sure all components are tight and
that steel lines, hoses and couplings are in good
condition.
6. Clear the area of all bystanders, especially
small children, before starting.
13. Review safety items with all personnel annually.
7. Stay away from overhead obstructions and
power lines when extending boom and
during operation and transporting.
Electrocution can occur without direct
contact.
8. Keep away from unloading boom when
moving, adjusting or setting. Keep others
away.
9. Clean reflectors, signs, and lights before
transporting.
10. Do not operate with leaks in the hydraulic
system.
11
2.3 MAINTENANCE SAFETY
2.4 HYDRAULIC SAFETY
1. Follow ALL the operating, maintenance and
safety information in the manual.
1. Make sure that all components in the hydraulic
system are kept in good condition and are
clean.
2. Support the machine with blocks or safety
stands when changing tires or working
beneath.
3. Follow good shop
practices:
-Keep service area
clean and dry.
-Be sure electrical
outlets and tools are
properly grounded.
-Use adequate
light for the job at hand.
4. Use only tools, jacks and hoists of sufficient
capacity for the job.
5. Before servicing, adjusting, repairing or
maintaining unit, ensure that unit power
source is completely shut down and can not
start up. Make sure all guards are in place
and properly secured when maintenance
work is completed.
6. Keep hands, feet, hair and clothing away
from all moving and/or rotating parts.
7. Clear the area of bystanders, especially
small children, when carrying out any
maintenance and repairs or making any
adjustments.
2. Replace any worn, cut, abraded, flattened or
kinked hoses or metal lines immediately.
3. Relieve pressure before working on hydraulic
system.
4. Do not attempt any makeshift repairs to the
hydraulic fittings or hoses by using tape, clamps
or cements. The hydraulic system operates
under extremely high-pressure. Such repairs
will fail suddenly and create a hazardous and
unsafe condition.
5. Wear proper hand
and eye protection
when searching for a
high-pressure
hydraulic leak. Use
a piece of wood or
cardboard as a
backstop instead of
hands to isolate and
identify a leak.
6. If injured by a concentrated high-pressure
stream of hydraulic fluid, seek medical attention
immediately. Serious infection or toxic reaction
can develop from hydraulic fluid piercing the
skin surface.
7. Before applying pressure to the system, make
sure all components are tight and that lines,
hoses and couplings are not damaged.
2.5
STORAGE SAFETY
2. Do not permit children to play on or around the
stored machine.
3. Store the unit in a dry, level area. Support the
base with planks if required.
2.6
TRANSPORT SAFETY
1. Make sure you are in compliance with all
local regulations regarding transporting
equipment on public roads and highways.
2. Make sure that all the lights and reflectors
that are required by local highway and
transport authorities are in place, are clean
and can be seen clearly by all overtaking
and oncoming traffic.
3. Attach securely to the towing vehicle using
a retainer on the drawbar pin and a safety
chain.
2.8
SAFETY SIGNS
1. Keep safety signs clean and legible at all times.
2. Replace safety signs that are missing or have
become illegible.
3. Replaced parts that displayed a safety sign
should also display the current sign.
4. Safety signs are available from your Distributor
or the factory.
How to Install Safety Signs:
4. Do not allow anyone to ride on the UltraVac® or towing vehicle during transport.
•
Be sure that the installation area is clean and
dry.
5. Reduce speed on rough roads and
surfaces.
•
Be sure temperature is above 50°F (10°C).
•
Decide on the exact position before you remove
the backing paper.
•
Remove the smallest portion of the split backing
paper.
7. Always use hazard warning flashers on
towing vehicle when transporting unless
prohibited by law.
•
Align the sign over the specified area and
carefully press the small portion with the
exposed sticky backing in place.
8. Add extra lights or use pilot vehicles when
transporting during times of limited
visibility.
•
Slowly peel back the remaining paper and
carefully smooth the remaining portion of the
sign in place.
2.7
•
Small air pockets can be pierced with a pin and
smoothed out using the piece of sign backing
paper.
6. Stay away from overhead obstructions and
power lines. Electrocution can occur
without direct contact.
TIRE SAFETY
1. Failure to follow proper procedures when
mounting a tire on a wheel or rim can
produce an explosion which may result in
serious injury or death.

4 OPERATION
4.1
TO THE NEW OPERATOR OR OWNER
The Walinga Ultra-Vac® is specifically
designed to vacuum up grain and move it in a
stream of pressurized air. A high capacity air
pump moves the air through the machine
creating a vacuum on the intake side and
pressure on the outlet side. Be familiar with all
operating and safety procedures before
starting.
Many features incorporated into this machine
are the result of suggestions made by
customers like you. Read this manual carefully
to learn how to operate the machine safely and
how to set it to provide maximum efficiency. By
following the operating instructions in
conjunction with a good maintenance program,
your Ultra-Vac® will provide many years of
trouble-free service.
It is the responsibility of the owner and operator
to read this manual and to train all other
operators before they start working with the
machine. Follow all safety instructions exactly.
Safety is everyone’s business. By following
recommended procedures, a safe working
environment is provided for the operator,
bystanders, and the area around the worksite.
Untrained operators are not qualified to operate
the machine.
19
4.2
MACHINE COMPONENTS
The air pump or blower is the key component in the
Ultra-Vac® and is driven by the diesel engine
through a belt drive system. The blower moves air
through the machine. On the intake side, the
blower creates a vacuum in the receiver tank and
intake lines for picking up grain. Grain is separated
from the stream of air in the receiver tank.
On the discharge side of the blower, the
pressurized air flows through the airlock where it
picks up a metered quantity of grain and moves it
out the lines to the discharge cyclone.
The airlock is rotated by the same power source
as the blower.
Fig. 4-1 Machine Components
Some items shown may be optional

h. Operate machine at 3/4 speed for 10
minutes to warm system before putting
under full load.
IMPORTANT
It is important to warm the hydraulic
system and blower reservoirs before going
to rated speed. The blower will not "warm
up" unless product is being conveyed.
i. Open airslide approximately 2 inches and
insert into the grain. Operate at this
setting until the machine is warm (10
minutes).
j.
After warm up period, bring machine to
capacity.
Fig. 4-12
Open Airslide
i. Increase engine speed to rated RPM.
ii. Close airslide until the intake line
starts to pulsate. Open slightly to stop
pulsing.
iii. Watch glass door in receiver tank to
determine how the product is moving
through the machine. The glass can
be covered but it should not be
stationary. If more product is being
drawn in than discharged, the product
will lay stationary against the window.
6.
Airlock Speed:
Refer to the Table 2 as a guide
for setting the airlock speed. Use the
flow control to adjust the speed and
count the revolutions using the arrow on
the wheel. It may be necessary to
experiment to determine the best
speed.
Fig. 4-13 Sight Glass in Receiver Tank
7. Maximum Capacity:
a. The nozzle should be placed into the grain
with the inlet below the surface of the
grain but not below the airslide. It is
recommended that some air be allowed to
enter with the grain to obtain the best
capacity.
b. Open the airslide about 2 inches to start.
Close the airslide until the machine starts
to pulsate. Then open it until the pulsing
stops. This will give a balanced grain and
airflow condition.
c.
Fig. 4-14 Nozzle Positioned
Watch the amount of grain on the window
in the receiver tank. Keep the window full
yet keep the product moving.
There are several ways to control the
amount of grain on the window:
i.
Decrease the amount of grain entering
nozzle.
ii.
Increase airflow by opening airslide.
iii. Increase airlock speed.
iv. Decrease airlock speed.
The airlock acts as a seal between the
vacuum and pressure sides of the circuit.
Increasing the airlock speed normally will
remove product from the receiver faster.
Refer to Airlock Speed Chart as a guide.
8. Use the regular nozzle until there is
approximately 12 inches of grain left in the bin.
Then switch to the clean-up nozzle to pick up
the last of the grain.
Fig. 4-15 Sight Glass
9. When using the clean-up nozzle, it is
recommended that the rubber intake hose be
installed to allow you to move around to pick
up the grain from the corners more easily.
10. Stopping Machine:
a. Remove the intake nozzle from the grain.
b. Allow the unit to run until the grain has
stopped coming out the cyclone.
c.
Stop the airlock.
d. Slow the engine speed down to low idle.
27
4.8
OPERATING (cont'd)
10. Stopping Machine Cont’d:
e.
Disengage hydraulic circuit and slowly
disengage PTO clutch.
f.
Stop engine by turning ignition key to OFF
and REMOVE.
11. Pre-Cleaner:
The machine is designed with a cleaner
between the blower and the receiver tank to
remove dust and dirt from the air stream.
Clean every 1000 bushels during normal
operating conditions. Clean or empty precleaner canister more frequently in dirty or
dusty conditions.
Fig. 4-16
Pre-Cleaner Canister
12. Specialty Crops:
Operating:
When handling specialty products such as
sunflower seeds, lentils etc, it is recommended
that the PTO speed be reduced by 1/4 to ½
rated RPM. This gives a gentler action through
the machine.
Run the airlock at a slower speed to allow
More time for the product to fill the pockets.
13. Operating Hints:
a. Try to keep the hoses full as possible to
have maximum capacity.
Fig. 4-17 Inside Bin
b. Pull the intake nozzle out of the grain and
empty the machine before changing
trucks.
c.
Maximum efficiency is obtained with large
airflow lines. Use the smaller rubber lines
only for final clean-up.
e. Route the lines to minimize bends and
corners. If a corner is necessary, use a
large radius elbow.
f.
Keep lines as short as possible to
minimize friction loses.
g. If long distance moving is required, push
the grain rather than pull.
h. If long distance moving is required, use
solid metal tubing whenever and wherever
possible.
Fig. 4-18 Loading Truck
4.8
OPERATING (cont'd)
i. If the airlock becomes jammed, use the
hydraulics to reverse the direction of airlock
rotation and clear the obstruction.
j. When on top of grain, do not push
the nozzle into the pile next to the feet.
The suction will pull the nozzle and
the operator into the pile. If the pile is deep
enough, the operator can be submerged
under the grain and suffocated.

5.2.1 BELT TENSION AND
ALIGNMENT
Rotational power from the engine is transmitted to
the blower through the belt drive. To obtain
efficient transmission of power and good belt life,
the belts must be properly tensioned and the
pulleys aligned.
Belts that are too tight will stretch and wear quickly
or overload the bearings on the input shaft or
blower; Belts that are too loose will not transmit
the required, power and will slip, overheat and
wear quickly. Pulleys that are not aligned will result
In rapid belt wear.

BLOWER OIL CHANGING AND
BREATHER CLEANING
The gears that drive and time the blower lobes run
in an oil bath for lubrication. Maintaining the
correct level in the reservoirs and changing every
100 hours will insure proper lubrication.
When maintaining the blower, follow this
procedure:
1. Clear the area of bystanders, especially small
children.
Fig. 5-13 Blower
2. Place all controls in neutral, stop engine and
remove ignition key or disconnect PTO
driveline before starting.
3. Unlatch and remove the belt drive covers.
4. Checking Oil Level:
a. Remove the level plug in each reservoir or
check the sight glass.
IMPORTANT
Check the level only when the oil is cold
and the machine is level.
b. Oil in the reservoir should just fill the
threads of the level plug hole.
c.
Add oil if low or allow the reservoir to drain
if overfilled.
IMPORTANT
It is necessary to maintain the recommended oil
level in the reservoir. A low level causes heating
from lack of lubrication and rapid gear and bearing
wear. Too much oil causes heating from oil
churning and can cause seal and breather leaks.
d. Install and tighten the level plug.
e. Install and secure the belt covers.
Fig. 5-14 Blower
5.2.2 BLOWER OIL CHANGING AND
BREATHER CLEANING (cont'd)
5. Changing Oil:
a. Place a collection pan or pail under each
drain plug.
b. Remove each drain plug.
c.
Flush each case and allow several
minutes to drain.
d. Dispose of the oil in an approved manner.
Do not contaminate the worksite with used
oil.
e. Install and tighten the drain plugs.
f.
Remove fill and level plugs.
Fig. 5-15 Blower
IMPORTANT
Condensation forms and collects inside
the reservoirs during machine operation.
Changing oil removes this water and
prevents it from damaging the gears and
bearings.
g.
Install and tighten the level and fill plugs.
h. Install and secure the belt drive covers.
6. Cleaning Breathers:
a. Remove breathers and blow out with an
air hose.
b. If dirt has caked up in the breather, soak in
good solvent and then blow out. It may be
necessary to use a probe to loosen the
dirt.
c.
Install and tighten the breather.
Fig. 5-16 Breathers
d. Install and secure the belt drive covers.
e. Clean vents in end plates located under
the blower on either side of the drain plug.

5.2.3
AIRLOCK
The airlock acts as a seal between the vacuum
and pressure sides of the machine and is located
at the bottom of the receiver tank. As the rotor
turns, a pocket is filled with material when it points
upward. As the pocket rotates, it is moved to the
bottom and is moved into the pressure side of the
system. The grain is picked up by the stream of
pressurized air and moved out the discharge
piping.
Efficient operation of the airlock requires a close fit
between the tips of the rotor and the case to
maintain a seal between vacuum and pressure
sides.
When checking or maintaining the airlock, follow
this procedure:
1. Clear the area of bystanders, especially small
children.
2. Disconnect the hydraulic lines from the tractor
to prevent airlock operation.

Below Receiver Tank
5.2.3
AIRLOCK (cont'd)
3. Checking Tip Clearance:
a. Checking the airlock can be done through
the inspection door.
b. Use a feeler gauge to check the clearance
between the tip and the case. Inspect
each tip over its entire width.
c.
The clearance of the tips must be
maintained at 0.004 to 0.006* inches at all
times. Adjust or replace tips as required
to insure system sealing. (*614 units .007
to .009).
d. Replace any tips that are bent, chipped or
broken.
e. File the ends of each replacement blade
so there is approximately 0.006 inches of
clearance between the ends and the
housing.
f.
g. Rotate airlock rotor slightly to set the
clearance between the blade and the
case. Be sure to set it at 0.004 inches of
clearance. Use a feeler gauge.
h. Tighten the center bolt first. Then the
others.
i.
Rotate the airlock and listen if it touches
the housing anywhere. A slight touch is
alright.
j.
Repeat mounting procedure with the other
blades.
k.
Turn the rotor after each blade is installed
to be sure it does not contact the case.
l.
Mount the new wiper blade. Be sure the
wiper contacts each tip slightly as the
airlock turns.
NOTE
Blades are reversible if not
excessively damaged.
Mount the blades to their respective vane
and tighten bolts finger tight.
m. Install and secure the airlock.
Fig.
5-18 Tip Clearance
4. Wiper Blade:
A wiper blade is located at the top of the
airlock to clean the tips as the airlock turns.
To check the wiper blade, follow this
procedure:
a. Open the access door on receiver tank.
n. Connect hydraulic lines and close access
door.
o. Pour 1/2 gallon Varsol in to the airlock.
Run the airlock at operating speed.
p. Clean thoroughly.
b. Reach into the top of the airlock and feel
the condition of the wiper blade.
c.
Replace it if it is damaged in any way.
5. Blade Replacement:
a. Disconnect hydraulic hoses from the
tractor.
b. Remove the quick connect plugs from
hydraulic lines.
c.
Lift the receiver tank off the airlock.
d. Remove the tips from the rotor and the
wiper blade from the housing.

5.2.4
AIR SYSTEM RELIEF VALVES
The air in this system is moved by the blower. It
draws air into the intake side and creates a
vacuum that can pick up and draw material into
the system. As the air moves through the blower,
it becomes pressurized and flows through the
airlock to move material out of the system and to
its destination. As the flow into the intake is
restricted, the vacuum will build until it exceeds the
setting of the intake relief valve. The valve opens
to supply a flow of air to the blower to prevent
overheating. A relief valve on the pressure side
will also open to allow air flow if the airlock (outlet
pressure side of the circuit) is restricted or
plugged.
Fig. 5-19 Vacuum Relief Valves
The vacuum side relief valve is set to open at 15
in. Hg vacuum and the pressure side at 15 psi.
Both must function at very close to these specified
levels to insure optimum capacity and
performance. After prolonged use, the springs in
these valves can weaken causing the valve to
open prematurely and affect machine
performance. Dirt and debris can get caught in the
valve seat allowing air leakage that affects system
performance.
To maintain air system relief valves, follow this
procedure:
1. Listen for the valves opening during operation.
They will sound like a popping or a whistle if
they are opening.
2. Install gauges on the vacuum and pressure
sides of the air system.
3. Watch the gauges to monitor the pressure in
the vacuum and pressure sides of the air
circuit.
4. Restrict the flow into the intake side of the air
system until you hear the valve open. The
vacuum gauge should read 15 in. Hg. If it
does not, replace valve.
5. Restrict the output side until you hear the
valve open. The pressure gauge should read
15 psi. If it does not, replace the valve.
6. Place all controls in neutral or OFF, stop
engine, remove ignition key and wait for all
moving parts to stop.
7. Remove old valve and replace it with a new
one.
8. Tighten valve into fitting to secure.
