IMPORTANT MESSAGE
YOU are responsible for the SAFE operation and maintenance of your Valmetal SILO UNLOADER
MODEL 880-SK. YOU must ensure that you and anyone else who is going to install, operate,
maintain or work around the SILO UNLOADER be familiar with the installation, operation and
maintenance procedures and related SAFETY information contained in this manual. This manual will
alert you to all good safety practices that should be adhered to while operating the SILO UNLOADER.
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 operation and maintenance
procedures and follows all the safety precautions. Most accidents can be prevented. Do not risk injury
or death by ignoring good safety practices.
SILO UNLOADER owners must give operation instructions to operators or employees before allowing
them to operate the machine, and at least annually thereafter per OSHA 1928.57.
The most important safety device 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.
A person who has not read and understood all installation, operating and safety instructions is not
qualified to operate the machine. 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 and could affect the life of the equipment.
Think SAFETY! Work SAFELY!

880 SK silo unloader Revision : 2013/01/21 7
Silage fermentation may produce several kinds of
gas, including carbon dioxide and nitric oxide
(which then produces nitrogen dioxide). Carbon
dioxide is non-poisonous, although it can cause
suffocation.
Nitrogen dioxide (NO2), however is poisonous. It
kills and injures people as well as livestock.
Nitrogen dioxide is a hazard on the farm because:
1. Exposure can be fatal.
2. Formation of nitrogen dioxide from nitric oxide
may occur whenever silage is made.
WHAT IS THIS GAS ?
The lethal gas is yellowish-brown and smells like
some laundry bleaches. After more oxidation, it
forms N2O5 which then forms highly-corrosive nitric
acid when combined with water. Since oxidation
may occur in the body, nitrogen dioxide can produce
permanent lung damage.
WHERE DOES IT HIDE?
Since nitrogen dioxide is heavier than air, it remains
beneath the air mass over the silage. It layers on top
of the silage below the upper edge of the top door or
settles down through the chute. It may also seep
through the drain at the base of the silo. If often
concentrates in the silo room and move into the
barn. It will leave a yellow stain on silage, wood or
other materials it contacts.
HOW TO MINIMIZE THE DANGER
While growing the crop :
1. Apply adequate nitrogen, but don’t over do. As
a guide, corn needs 1.2 lbs. of N per bushel
yield; oats and/or sudangrasse used for silage
should have no more than 75 lbs. of N available
for each harvest. Since this includes both N in
the soil and that applied, follow the
recommendations on soil analysis reports.
2. After a drought, rapid nitrate uptake occurs in
plants following rain. So, harvest the crop
before fall rains, or wait at least five days after a
rain.
3. Plants damaged by hail or frost should be
harvested immediately before they take up
nitrates.
4. To reduce the amount of nitrate going into
silage, cut higher than normally (10-12 inches).
Most nitrates are in the lower stalk.
While filling the silo :
1. Be on the alert for bleach-like odors and/or
yellowish-brown fumes in or near the silo.
Small amounts of the gas may not be visible or
easily detected by smell, but are still dangerous.
(Greatest danger is 12 to 60 hours after filling
silo).
2. If you must enter the silo, run the silage blower
for 15 or 20 minutes first. Never enter the silo
alone during the danger period and always have
someone outside of the silo to communicate
with.
3. If you experience the slightest throat irritation or
coughing while in the silo, get into fresh air
immediately. Call your doctor as soon as
possible, indicating that you have been exposed
to silo gas.
DANGER
NEVER ATTEMPT TO RESCUE A PERSON
WHO HAS BEEN OVERCOME BY SILO GAS
WITHOUT THE AID OF OXYGEN-
SUPPLYING BREATHING EQUIPMENT.
FAILURE TO HEED MYA RESULT IN
SERIOUS PERSON INJURY OR DEATH.
After filling the silo :
1. Ventilate silo room to outdoor air for at least
two weeks.
2. Keep any door between silo room and barn
closed to minimize any risk to livestock.
3. Remove upper silo chute doors down to the
settled silage level to prevent build-up of gases
in silo.
DANGER: SILO GAS IS HAZARDOUS
880 SK silo unloader Revision : 2013/01/21 8
2.1 GENERAL SAFETY
1. Read and understand the Operator’s Manual and all
safety signs before operating, maintaining or
adjusting the SILO UNLOADER.
2. Have a first-aid kit available for use should the need
arise and know how to use it.
3. Have a fire extinguisher available for use should the
need arise and know how to use it.
4. Wear appropriate protective gear. This list includes
but is not limited to :
- A hard hat
- Protective shoes with slip resistant soles
- Protective glasses or goggles
- Heavy gloves
- Hearing protection
5. Install and secure all guards before starting.
6. Wear appropriate ear protection for prolonged
exposure to excessive noise.
7. Clear the area of people before starting the unit.
8. Review safety related items annually with all
personnel who will be operating or maintaining the
SILO UNLOADER.
9. Always call upon a qualified electrician for electrical
problems.
10. Do not get near the Unloader auger when it is in
operation. The auger is equipped with very
sharp knives. These knives can seriously injure
anyone who gets close to the auger. Keep hands
and feet away from auger. Also, make sure no
on is near the auger when it is operating.
2.2 OPERATING SAFETY
1. Read and understand the Operator’s Manual and
all safety signs before operating, servicing,
adjusting, repairing or unplugging.
2. Be certain that all guards and shields are secured
before starting or operating.
3. Make certain everyone is clear of equipment
before applying power.
4. Always lock out power source before entering a
silo.
5. Keep hands, feet, hair and clothing away from
moving parts.
6. Be sure main switch is off before resetting
motor thermals.
7. Never stand underneath a suspended silo
unloader.
8. Never work or crawl on a silo unloader that is
suspended. Always lower silo unloader to silage
level to work on it.
9. Always leave at least three feet of suspension
cable between the suspension arms and the cable
pulleys. Snubbing the unloader any tighter at
the top could cause undue strain on the
suspension, which might cause the unloader to
fall.
10. Never go into a silo to work on a moving silo
unloader, stay in silo chute to observe operation.
11. Never disconnect the electrical cord connector if
the silo unloader is running because moisture
conditions inside the silo could give you a
severe shock.
12. Always inspect suspension cables carefully
before you raise unloader to top of silo.
13. Beware of silo gases, read carefully page 6.
THINK SAFETY and live longer.
A careful operator is the best insurance against an accident.
The complete observance of one simple rule would prevent many thousands of serious injuries each year.
That rule is ¨NEVER ATTEMPT TO CLEAN, OIL, OR ADJUST A MACHINE WHILE IT IS IN MOTION¨.
Regardless of care used in the design and construction of farm equipment, there are many points that cannont be
completely safeguarded without interfering with accessibility and efficient operation.

880 SK silo unloader Revision : 2013-01-21 44
ADJUSTING THE SILO UNLOADER
PRESSURE WHEEL, GUIDE WHEEL AND WALL WHEELS.
1-The pressure wheel should run against the silo wall at all times. Its purpose is to hold the auger wall wheels in contact with the silo
wall and to insure that all material is removed from the wall area. Normal adjustment of the pressure wheel is when the spring is extended
4". During extremely frozen conditions, it may be necessary to increase the spring force. This is done by moving the hook on the spring to
a different chain link when tension is released. After changing pressure wheel adjustment, you should always watch the unloader rotate
around the silo at least once to make sure that your adjustment will not cause the pressure wheel to exert force on the unloader. Observe
operation from safety of silo chute.
2-The unloader is kept centered in the silo by the side guide wheel , this is the one extending out at approximately a 90 degree angle
from the auger. The guide wheel should run against the silo whall at all times. You can get the correct setting for this wheel by first
measuring the maximum silo diameter. Then extend the wheel so that the distance from near side of the impeller housing to the edge of
the wheel is equal to one half the maximum diameter of the silo. You can tell when this adjustment is incorrect by a pile of undisturbed
silage being left in the center of the silo directly under the impeller housing. If this occurs, the wheel is probably not extended out far
enough.
3-The position of the wall wheels in relation to the auger, determines the closeness of the chipper knives to the silo wall. This is very
critical in freezing weather and should be set so the chipper knives are within 1/8" of the silo wall. Adjust by loosening the bolts wich
secure the wall wheel bracket to the auger frame and turn the adjusting screw out or in to obtain the correct adjustment. After you make
any change in the wall wheel setting, rotate the unloader around the silo to make sure the chipper blades do not hit the wall at any place.
Observe operation from safety of silo chute. The trailing wheel will generally be in contact with the silo wall except near the silo doors.
As the machine approaches a door, the lead wheel will come in contact with the flattened wall and protect it from being damaged by the
chipper knives.
880 SK silo unloader Revision : 2013-01-21 45
OPERATING THE SILO UNLOADER
For trouble-free operation of your silo unloader, the following operator schedule is recommended.
After turning off the silo unloader at the end of feeding, raise the machine off the silage pack.
During extreme cold weather if the motor switch is turned on and off momentarily after raising, this will clear the impeller
of any material left in it for easier starting at the next feeding. To begin feeding again, lower the unloader the same
amount that it was raised previously. Now turn on the motor switch.
When you turn on the silo unloader, the needle will flick over to a maximum reading. The ammeter is designed so that this
initial surge of current will not damage it. A couple of seconds after starting, the ammeter will level off at the normal load
current for your motor. Most reliable, efficient operation and highest capacity will be obtained when you operate your silo
unloader motor in its proper amperage range.
After the unloader has completed its revolution around the dilo, the silage flow will decrease and the unloader should
again be lowered the amount necessary to load the motor to rated current. Observation will tell you how many turns of the
crank are necessary to do this. Five turns lower the unloader about one inch. Slight overloading or underloading will not
damage the equipment and is much better for it than continuous jockeying up and down the hoist.
A complete revolution around the silo will take about 5 minutes. Should any obstruction occur in the silo during this 5
minutes period, a built in clutch will prevent damage to the equipment.
If the impeller should become plugged due to long hard-to-handle material or rotten material from the top of the silo, the
stall current of the motor is such that it will trip the overload device in the control box at the bottom of the silo before
damage is done to the motor or the unloader. Whenever this happens, you should go up and find the cause of the
stoppage before attempting to restart the unloader.
The curved discharge chute is designed to allow maximum lowering for a given size of silo before it is necessary to move
the discharge chute down to another silo door. This discharge chute should be lowered every two doors. This would
be a good opportunity for you to take the time to check your unloader.
DISCONNECT AND LOCK OUT POWER SOURCE BEFORE ADJUSTING
OR SERVICING UNIT.
1- Before entering the silo chute be sure the power to the unloader has been turned off and locked.
2- If your unloader is equiped with a remote control switch, lock the stop button down so the unloader cannot be
started accidentally and take the remote switch with you.
3- As soon as you climb the silo chute to the door through which the material was being thrown out, reach into the
silo and unplug the power cord to the silo unloader.
4- Remove the torque arm bracket from the door frame and lower it.
5- Unless equiped with cord looping, unhook the power cord grip and reattach it to a ladder rung just above
the next discharge door you will use.
6- Before leaving the silo you should check the machine over thoroughly.
7- After you are out in the silo chute, plug the cord connectors together before climbing down.

The lubrication level in the worm gear hoist should be checked every 6 months and every time you will raise the
unloader to the top of silo. The oil level should be visible in the oil level sight plug. If oil is low, add
EP 80-90 extreme pressure gear lubricant. Lubricant should be changed annually.
The hoist cable assembly will have a much longer life if lubricated with motor oil or gear lubricant.
You should do this when the unloader has been raised to the top of the silo and all the cable is wrapped on the
hoist.Paint on a liberal coat and allow it to drip off.
880 SK silo unloader Revision : 2013-01-21 50
IMPELLER BLADES AND V-BELTS
IMPELLER BLADES
The impeller on this silo unloader can be operated with the blades rigid, as sent from the factory, or as swinging
blades by removal of 3 locking bolts. If the blades are left rigid, the maximum throwing power will be achieved. It
is recommended to remove the 3 locking bolts to allow the blades to swing if material being unloaded causes
extreme gumming or during extreme cold weather operation. If the blades are allowed to swing, silage will fall out
from the discharge chute when the machine is started or stopped and anytime the unloader is overloaded causing
drop in motor speed.
The blades are also adjustable by loosening the 3 grade 5 carriage bolts securing the cupped blade to the blade
bracket. The clearance between the blade tip and rim sheet should always be within 1/32". Proper tightening torque
on these bolts is 40 lbs-ft.
V-BELTS
During initial unloading operation, some stretch of the impeller and auger belts may occur, and belts should be
readjusted. To tighten these drive belts, loosen the 4 horizontal carriage bolts through the motor mount, move
motor mount away from impeller with take-up "J" bolt and tilt motor plate upward with 1/2" hex. bolts on under
side of motor mount. If auger belt becomes tight before impeller belt, then motor plate must be lowered while
moving motor mount further away from impeller. If impeller belt becomes tight before auger belt, then motor
mount must be moved back toward impeller while raising motor plate with set screws. Adjustment in the
horizontal direction and upward direction must be made together so that both belts become tight at the same time.
The correct tension for the impeller belt may be determined by placing a 6 pounds force at the mid-point between
the 2 pulleys. This should depress the belt 1/4" to 3/8". The correct tension for the auger drive belt may be
determined by placing a 6 pounds force at the mid-point between the 2 pulleys. This should depress the belt 1/8" to
3/16".
Avoid overtightening belts. It may cause bearing damage.
After the belts are properly tensioned, tighten the 1/2" lock nuts on the 1/2" adjusting bolts, lock the 3/8" nut on
take-up "J" bolt, and tighten four horizontal carriage bolts.

CONVERTING FROM UNLOADING TO DISTRIBUTING
DANGER
DISCONNECT AND LOCK OUT POWER SOURCE BEFORE
CONVERTING TO UNLOADING.
IMPORTANT :
Impeller must not be turning when using distributor.
On the line shaft drive model, the impeller V-belt must be removed to prevent
the impeller from turning.
On independent ring drive only :
Cut power to impeller and auger motor by switching to off the 60 amp. Breaker

ON THE LINE SHAFT DRIVE SYSTEM, THE IMPELLER V-BELT MUST
BE REMOVED TO PREVENT THE IMPELLER FROM TURNING.
On powered distributor, guide the motor cord through the upper pedestal hole and down through the pedestal
and impeller.
Pull cord through lower opening in impeller and connect to female connector from the circuit breaker box.
880 SK silo unloader Revision : 2013-01-21 55
Release spring pressure on the pressure wheel.
Loosen the lock screw for the guide wheel and slide the wheel all the way in. Leave the set screw loose so the
wheel can pivot for raising.
Lubricate all grease points and check oil level in the gearboxes.
Adjust the wall wheels so they are all the way out (toward silo wall).
Check for condition and proper tension of belt on powered distributor. Operate the unloader around the silo at
least once to make sure it moves freely. Observe from the safety of the silo chute. Stop the unloader with
the auger near the main leg of the suspension system or leg nearest chute. You must be able to reach the auger
shroud from the silo door.
Flip the vertical raising wheel against the silo wall. Make sure it turns freely.
Check the condition of the support cables and the cable clamps. Replace the cables if they are frayed.
Place the main power cord connector on the auger shroud so it can be reached from the silo doors.
Raise the unloader to the top of the silo. Always leave about 6’ of suspension cable between the
suspension arms and the cable pulley on the hexapod. This reduces lateral forces on the hexapod. The
unloader can be raised higher for additional silo capacity at the very end of silo filling after the silo
has been filled to this level.
ATTENTION : Always have someone available to observe the unloader from the safety cage platform
or from the top of the silo chute to announce when the unloader is nearing the top.
Never enter a silo under a suspended silo unloader.
Take the power cord up the silo chute and hang the cord support on a ladder rung near the top of the silo.
(Unless unloader is equipped with a cord looping kit.)
Flip the vertical raising wheel to the stored position (away from the silo wall).
Plug in the unloader-distributor (make sure there is sufficient slack in the power cord to prevent pulling the
connection apart) and let it rotate around the silo until the guide wheel is near the silo door.
Turn the guide wheel caster to a level position and tighten its set screw.
Continue operating the unloader around the silo at least one to make sure it moves freely.
Do not connect torque chain to door frame during filling. If optional torque arm is used, store it in storage
bracket. Do not put in door frame during filling.
880 SK silo unloader Revision : 2013-01-21 56
OPERATING THE DISTRIBUTOR
Always make sure that the unloader-distributor is operating when filling. If the time between loads is less than
three minutes, it may be advisable to allow it to operate continuously to reduce the likelihood of filling with the
distributor not moving.
A normal fill pattern is one which is high and level around the silo wall and sloppes into a low point at the center,
making a large inverted cone. The standard distributor will achieve the pattern in 12’ through 18’ silos. A
powered distributor should be added for larger size silos.
Should the fill pattern become uneven, the distributor should be deliberately parked and fill pattern evened out by
running one or two loads toward the low side.
When the silo is nearly full (check this often), someone must watch from the outside to insure that material is not
dumped on the unloader. The unloader may be raised as high as possible and still keep the wall wheels below the
hexapod plates for topping off the silo (see note below). When using powered distributor the inverted cone may
be filled by disconnecting the powered distributor and operating the unloader, thus allowing the material to fall
near the center of the silo and fill in the inverted cone.
IMPORTANT :
Note : Always have someone available to observe the unloader from the safety cage platform or from the
top of the silo chute to announce when the unloader is nearing the top.
After the silo has been topped off and leveled, the unloader-distributor should be cleaned off and raised out of
contact with the acidic rust producing silage during the fermentation process. It is also a good idea to convert the
machine to unloading at this time since the silo filling blower is usually still set up and can be run to provide
fresh air to the persons in the silo. This is accomplished by reversing the conversion steps listed in the converting
to distributing section.
