TO THE NEW OPERATOR OR OWNER
The Walinga® Central Vacuum System is designed to
vacuum up grain, powder or other granular material
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.
In addition to the design and configuration
of equipment, hazard control and accident
prevention are dependent upon the awareness,
concern, prudence and proper training of
personnel involved in the operation, transport,
maintenance and storage of this equipment.
It is the responsibility of the owner or 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.
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
Central Vacuum System will provide many years of
trouble-free service.
19
4.2
MACHINE COMPONENTS
The machine is designed with an air pump or blower
drawing air and material into the intake wands, hose
and piping. An electric motor powers the blower
through a set of belts. A large filter on the intake side
removes dust from the air intake before it enters the
blower.
Seed, powder or other loose granular material is
drawn into the system through the wands and hose/
pipes. Material drops out of the air stream when it
enters the cyclone. From the receiver cyclone, the
material drops into the turning airlock that discharges
it from the system.

The Walinga® Central Vacuum System is used to pick
up and move grain, powder or other granular material
from one location to another on a stream of air. Before
starting, the operator has the responsibility of being
familiar with all operating and safety procedures and
following them.
Each operator should review this section of the manual
at the start of the season and as often as required to
be familiar with the Central Vacuum System. When
operating the machine, follow this procedure:
1.
Clear the area of bystanders, especially small children before starting.
2. Review and follow the pre-operation checklist (See
Section 4.4).
3. Attach the components required to pick up the
dust or granular material as appropriate for your
application.
a. Check the integrity of the coupler gasket seal.

FIG. 9 GATHERING MATERIAL
27
8. Air Slide:
Each wand is designed with an air slide on the
tube that can be used to control the amount of air
entering the machine along with gathered material. Always move the wand so that sufficient air
enters the system to move the material and cool
the blower. Do not starve the system for air.
Mostly Closed
Mid-Range
Open
FIG. 10 AIR SLIDE (TYPICAL)
10. Nozzle Position:
Do not place the nozzle between your feet when
picking up a deep pile of granular material. The
nozzle can pick up sufficient material to draw the
operator into the pile and suffocate them. Always
pick up material away from nozzle.
28
11. System Grounding:
a. Granular material flowing through pipes, hoses or lines can generate an electrical charge
that will create electrical discharges, static
and/or sparks. In high dust environments
sparks or electrical discharges can set off an
explosion. This static charge condition can be
very annoying to an operator.
The system is designed using steel lines, metal arm lock couplers on all fittings, a metal spiral strand in the hose that is attached to each
fitting and metal pick-up components to maintain electrical ground continuity and through
the entire system. Only when nonmetal components are used or the electrical continuity
is broken can sparks or shocks occur. Use an
ohmmeter to check the electrical continuity
of the system on a weekly basis as a maintenance item and/or if anyone feels a shock.
b. Use an ohmmeter to check the electrical continuity of all swivel couplings on a weekly basis as a maintenance item and/or if anyone
feels a shock.
Cam Lock
Wand
FIG. 11 CAM LOCK GROUNDING (TYPICAL)

13. Receiver Cyclone/Airlock:
The system is designed to direct the system intake airflow into a cyclone receiver where the
large, heavy particles fall out into the airlock. The
airlock is located under the receiver tank. The collected material drops into an airlock compartment
as it turns. As the rotor turns and a compartment
moves from its up position to its down position, the
material in the rotor compartment will fall out into
the hopper bin.
FIG. 13 RECEIVER CYCLONE/AIRLOCK
14. Airlock Unplugging:
If a large piece of debris is drawn into the intake,
it can get into the airlock, stall it and have to be
removed. To unplug, lock-out tag-out master control panel. Remove obstruction through the access
door on the receiver tank. Rotate airlock after obstruction is removed to be sure airlock turns freely
and has not been damaged. Repair airlock if damaged before resuming work.
FIG. 14 AIRLOCK ACCESS
15. Lock-Out Tag-Out Procedure:
It is recommended that the customer institute a formal lock-out tag-out procedure for their workplace.
In simple terms, this policy would require every
person that will be servicing, adjusting, maintaining or unplugging the system to lock out the master panel and place a tag on it before working on
the unit. Only the person with the tag can unlock
the master switch to allow it to be turned on. This
prevents unauthorized people from starting up the
system and maintains control by the serviceman
working on the system.
31
16. Secondary Cleaning Cyclone:
The Central Vacuum is designed with a primary
cleaning cyclone that removes the majority of the
material picked up by the system and removed
through the airlock into the bin. In addition, the
system is designed with a secondary cyclone to
remove additional debris from the airflow before it
enters the filter cannister.
Cyclone
The bottom of the secondary cyclone is designed
with a flapper door on the bottom of the assembly
to remove any accumulated debris. Open flapper
door to empty the cyclone at the start of each day
for the best results or more often if required.
Flapper Door
FIG. 15 SECONDARY CLEANING CYCLONE
32
17. Operating Hints:
a. Lock out tag out master panel before performing any service or maintenance work on
machine or unplugging airlock.
b. Maintain electrical continuity through all
components to prevent sparks, shock or
electrical discharges. Do not use plastic
components.
c. Clean the intake filter whenever the vacuum
relief valve goes off. Replace filter when cleaning frequency is too short.
Filter
Basket
FIG. 16 INTAKE FILTER SYSTEM
d. Remove obstructions from airlock through

e. At the start of each day, open flapper door on
the bottom of the secondary cyclone to empty
the compartment and minimize the amount of
dirt getting to the filter mechanism.
FIG. 18 FLAPPER DOOR
f.
Verify that each female connection has a rubber gasket seal in good condition.
FIG. 19 GASKET SEAL (TYPICAL)
34
g. When on top of material, 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 material and
suffocated.

5.2 MAINTENANCE
By following a careful service and maintenance program on your machine, you will enjoy many years of troublefree use.
5.2.1 BELT TENSION AND ALIGNMENT
Rotational power from the electric motor 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 motor 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.
Follow this procedure when checking and adjusting
belt tension and pulley alignment.

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.
Sight Glass (Typical)
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.

5.2.3 AIRLOCK
The airlock acts as a seal between the vacuum and
atmosphere sides of the machine and is located at
the bottom of the collector cyclone tank. As the airlock
rotor turns, a pocket is filled with material when it
points upward. As the pocket rotates, material is
moved to the bottom where the material drops out of
the pocket into the discharge pipe.
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 atmosphere sides.
When checking or maintaining the airlock, follow this
procedure:
1.
Clear the area of bystanders, especially small
children.
2. Turn machine off, lock out tag out master control panel and wait for all moving parts to stop
before starting maintenance work.
FIG. 41 AIRLOCK
3. Checking Tip Clearance:
a. Checking the airlock can be done through
the inspection door.
Airlock
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.
d. Replace any tips that are bent, chipped or
broken.
NOTE
Blades are reversible if not excessively
damaged.

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.
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:

there is approximately 0.006 inches of clearance between the ends and the housing.
g. Mount the blades to their respective vane and
tighten bolts finger tight.
Schematic
FIG. 43 AIRLOCK
h. Loosen and remove drive chain.
i.
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.
j.
Tighten the center bolt first. Then the others.
k. Rotate the airlock and listen if it touches the
housing anywhere. A slight touch is alright.
l.
Repeat mounting procedure with the other
blades.
m. Turn the rotor after each blade is installed to
be sure it does not contact the case.
n. Mount the new wiper blade. Be sure the wiper
contacts each tip slightly as the airlock turns.
o. Install and set chain drive tension.
p. Install and secure chain drive guard.
q.
Clean thoroughly.
51
5.2.4 CHAIN TENSION
Rotational power to drive the airlock is provided by
an electric motor through a chain drive system. To
obtain good chain life, the chain must be properly
tensioned and the sprockets aligned. Chains that are
too tight will stretch and wear quickly or over load the
bearings. Chains that are too loose will not transmit
the power evenly and will wear out quickly. Misaligned
sprockets will rapidly wear the chain and sprockets.
When checking chain tension and alignment, follow
this procedure:
1.
Clear the area of bystanders, especially small
children.
Chain
2. Turn machine off, lock out tag out master control
panel and wait for all moving parts to stop before
starting maintenance work.
3. Remove guard over chain drive system.
4. Pull on the middle of the slack side of the chain.
The chain is properly tensioned when the chain
will move 1/4 inch (6 mm).

5.2.5 GEARBOX OIL
a
The airlock is driven by an electric motor that is
attached to a gearbox attached to the airlock. The
gearbox is equipped with a drain, level and fill plug.
Every 40 hours, the oil level should be checked.
Every 100 operating hours or annually, whichever
comes first, the oil should be replaced. Check more
frequently if there are leaks around any of the plugs
or shaft seals. When checking oil level or changing
oil, follow this procedure (Refer to manufacturer's
manual or Walinga® blower oil.):
1.
Run the machine until the gearbox is warm. Warm
oil will remove more contaminants than cold, stagnant oil.
2. Stop machine.
3. Place all controls in their OFF position and wait 30
seconds for the airlock to stop turning.
4. Turn power OFF at master control panel and lockout tag-out.
5. Checking Oil Level:
a. When the gearbox is cold, remove the level
plug from the side of the gearbox.
b. When the oil just fills the threads of the level
plug, it is at the correct level.
c. Add oil through the fill plug as required.
