2) Turn the Control Switch on the remote control cord to the OFF position.
3) Turn the Main Disconnect Switch to the OFF position.
4) Disengage the PTO.
SAFETY NOTE:
DO NOT FILL THE HOPPER TO CAPACITY AT THE END OF THE DAY. THE MATERIAL
WILL COMPRESS AND CAN CAUSE MACHINE LOCKUP DURING THE NEXT ST ART -UP.
Mechanical Settings:
The controls of your machine contain the blower and slidegate controls to adjust your machine for
each application and type of fiber. (See illustration 7 on page 17.) Blower control (air) and slidegate
(material feed) are adjusted according to:
TYPE OF MATERIAL:Cellulose and fiberglass have different textures and densities that
respond to machine settings.
HOSE:Corrugations or roughness of interior surface, diameter, length and
elevation of hose will also require varying adjustments.
WEATHER CONDITIONS:Temperature and humidity may require day to day adjustment of
machine settings.
Blower Control and Slidegate General Settings:
Blower control can increase or decrease the amount of air in the system, affecting the velocity
(speed) and spread rate (coverage) of fiber. (See illustration 7 on page 17.) The blower control valve
is used for controlling air pressure and amount of air flow.
Opening or closing slidegate (material feed) controls the amount of fiber dropping into the airlock
which changes the production rate (lbs. per hour). (See illustration 7 on page 17.) For calibration
purposes the scale located on the machine indicates how many inches the airlock slidegate is opened.
Rev. Date: 12/14/10Page 16
MODEL #5200-P
The blower and slidegate controls working together
affect the distance fiber can be blown through a hose without
plugging. These controls also affect the accurate blowing of
fibers for spraying applications.
These settings control the following:
• Density of fiber blown in application.
• Velocity of material impact when spraying.
• Dust on open blow.
• Material spread rate or coverage.
• Production rate (lbs. per hour blown).
General Blower Control and Slidegate Settings for Open Blow:
With the slidegate closed and blower control valve on low (valve open), turn agitator-feed and
blower on. Fill hopper with insulation and adjust blower valve and slidegate. Move controls
proportional to each other. (i.e. If blower valve is half open, slidegate should be half open.) As hose
length is increased, air pressure/volume is increased by closing off the blower valve while closing the
slidegate proportionally. This will increase the distance fiber can be blown through the hose, while
decreasing the blowing production rate (lbs. per hour blown). (See illustration 7)
Illustration 7
Shredder Assembly:
This unit is supplied with a shredder assembly; airlock/agitator speeds are preset at the factory. No
further sprocket setting speeds are needed, as this system will accommodate most fibers and
applications. However, the shredder and agitator direction can be adjusted as described below.
Shredder & Agitator Adjustment:
Illustration 8Illustration 9
Unidirectional Rotation (See illustration 8) is preferred as an all-around setting for a combination of
materials and applications. This setting provides the greatest coverage and best control for internal
wetting (stabilized) and open blow applications.
Center-Down Rotation (See illustration 9) force feeds the fiber into the airlock at a faster rate. This
direction provides the greatest production for cellulose fibers in an open attic blow application
although coverage may decrease.

The purpose of the airlock seal is to trap air and fiber until it rotates 180O to the 6:00 o'clock position.
At this point, fiber is pushed by air from the blower, out of the chamber. Worn or damaged seals allow
air and fiber to escape back into hopper, thus reducing production and coverage. When it is necessary
to replace seals, follow these directions:
Remove chain and air hoses from both input and output of airlock. Using a 9/16” socket, remove
hold down bolts from airlock. Lower the front of the airlock down by loosening the jamb nuts and
turning the liftbolts counter clockwise. Slide the airlock out of the machine. (See illustration 10) Airlock
rotor plates that are damaged (bent) will need replaced. (Refer to Rotor Plate Replacement below.)
Take out rubber seal by removing seven plate fastening bolts and nuts and top plate. The base plate
will remain attached to airlock shaft. To install a new seal, reverse procedure. Seal should be inserted
tight against the back base plate, pressing the lower tabs of the seal down under the adjacent seal with
a flat blade screwdriver. Make sure all bolt holes are aligned while each side of seal is equally pressed
against the end plates, before tightening bolts. Seal should be bent forwards for counter clockwise
rotation. (See illustration 12)

1.Remove damaged baseplate assembly from shaft using
ratchet drive wrench with extension and 9/16" socket.
2.Check seal for wear and damage. (Installing seal and top
plate on the bench is quick and easy). Remove bolts
from plate assembly and replace with new seal. Make
sure seal and top plate are assembled on correct side of
base plate before assembling in airlock. Seal should
press backward towards top plate when
rectly into airlock chamber. (Illustration 12)
3. Install the rotor plate assembly into the airlock. The
airlock runs counter clockwise viewing it from the
sprocket drive shaft. (Illustration 12) Align the base plate
with holes on airlock shaft using a tapered punch. Cau-tion: Do not mount rotor plate backwards. If installed

(Note: Entire rotor plate assembly
may be removed and replaced. This
procedure maybe easier than
replacing just the seals.)

improperly, damage to seals will result and put undue stress on agitator motor. This causes
overheating and poor production. Seal should be bent backward to allow for a clockwise rotation
of rotor.
5. As rotor plate is installed, press bottom tab of seal under adjacent seal with flat blade screwdriver. (See illustration 12 on page 20)
Chain: (Adjustment) (#50 Nickel Plated)
A smooth operating chain drive should have a slight sag on the idler side of the chain. New chains
should be installed under slight tension as they will elongate a small amount due to seating of pins and
bushings during the first few days of operation. Chain should be kept in good condition by proper
lubrication (use dry film lubricant Dow 321) and occasional cleaning. Soaking chain in container of 10
weight oil will provide for internal lubrication of pins and bushings. However, excess oil must be
drained and wiped away as excessive lubrication will cause fiber accumulation on chain. Worn out
chain should be replaced. When chain is replaced, worn sprockets should also be replaced,
preventing further damage to new chain.
Sprockets:
Check Sprockets For Wear. Misalignment and/or loose sprockets and improper chain tension
causes the premature wear of chain and sprockets. All sprockets, except speed reducer and idler
sprockets, have been secured with a medium grade Loctite (general purpose thread locker), to prevent
gradual movement. The set screws and key are also inserted with a medium grade Loctite. If sprocket
is difficult to remove, it may be heated with a propane torch to loosen.
Caution: Do not overheat sprocket or damage to bearing will result. A pulley or bearing puller
can then be used to remove the sprocket and key. Replace new sprocket on shaft with key and
medium grade Loctite applied to shaft. Align sprocket with corresponding sprocket, using a
straightedge placed along face of teeth and tighten set screws.
Bearings:
Agitator Bearings in hopper are double-sealed, self aligning ball bearings. They have grease fittings
and should be periodically lubricated. At least every 3 months. If bearings produce noise or heat (too-hot-to-touch), the bearings should be replaced.
Agitator Bearing Replacement:
Spray area with rust penetrant (WD-40). Remove sprocket (See SPROCKET section above).
Remove the four bolts from bearing flange. Loosen set screws on bearing hub at each end of agitator
shaft. Since all set screws are installed with a medium grade Loctite, a propane torch may be used to
assist in removing them. Do not overheat unit, causing shaft to expand. Using a rubber mallet, drive
agitator shaft an inch in one direction, creating a space between hopper and bearing unit. A bearing
puller can then be used to remove the bearing. Eliminate any metal burrs from shaft with file and install
new bearings with felt seals. Use a medium grade Loctite on set screws before securing bearing to
shaft. (Check shaft diameter before ordering bearings)

BRIDGINGA tendency for fiber to cling in the hopper forming an air pocket above the
airlock. This hinders the normal feeding process of the machine.
CFM(Cubic feet per minute). A measurement of volume or quantity of air
flowing at a certain rate, or air moving capability, of a blower. It is the
volume of air moved per minute. Higher volume provides increased
coverage and velocity of fiber as it leaves the hose.
CHECK V AL VEA valve that allows air to flow in one direction only. When mounted on
the outlet of the blower, it protects the blower from fiber contamination through the air hose when using one blower. When the blower stop s,
the valve closes.
COMMERCIALThe application of fiber with adhesive to a surface which will remain
SPRAY-ONexposed. The application must therefore be impacted in a smooth,
uniform manner.
COVERAGERefers to the amount of fiber coverage, usually measured in square
feet, according to the R-value desired. This information is given on the
fiber package.
NEW CONSTRUCTIONThe spray application of fiber with water or adhesive into an exposed
WALL CA VITY SPRA Ywall cavity to later be covered with drywall sheathing, etc.
PSIPounds of pressure per square inch of force exerted on a surface
by air or liquid. High-pressure blowers push the fiber through the hose.
Higher pressure provides less hose plugging and increased compaction
in side wall.
PRODUCTION RATEPounds of fiber blown per hour.
RPM(Revolutions per minute). Speed at which the shaft of a rotating device
(i.e. blower fan, agitator) is moving.
R-V ALUEResistance value. A precise measurement of the insulation’ s resistance
to heat transfer. The higher the resistance value, the slower the heat will
transfer through the insulating material.
RETRO-SIDEWALLThis refers to the installation of fiber into an unexposed wall cavity . Fiber
is usually installed through holes drilled into the exterior siding.
SETTLED DENSITYThe point at which the fiber will not continue to settle further. Any
insulation blown will have a certain amount of progressive settling that
occurs over a period of time. Following the fiber manufacturer’s
recommendations for bag rate coverage will provide useful information
to accommodate for settling.
SETTLINGCompression or compaction of insulation fibers caused by the weight of
the material, vibration of structure, temperature, and humidity cycles.
