REMEMBER:
THINK SAFETY
A CAREFUL OPERATOR IS THE
BEST INSURANCE AGAINST AN
ACCIDENT!
OM-00229-A
No accident-prevention program can be successful without the whole-hearted
cooperation of the person who is directly responsible for the operation of the equipment.
To read accident reports from all over the country is to be convinced that a large
number of accidents can be prevented only by the operator anticipating the result before
the accident is caused and doing something about it. No power-driven equipment,
whether it be transportation or processing, whether it be on the highway, in the harvest
field, or in the industrial plant, can be safer than the person who is at the controls. If
accidents are to be prevented--and they can be prevented--it will be done by the
operators who accept the full measure of their responsibility.
It is true that the designer, the manufacturer, and the safety engineer can help;
and they will help, but their combined efforts can be wiped out by a single careless act
of the operator.
It is said that, "the best kind of a safety device is a careful operator." We, at
Unverferth Mfg. Co., Inc. ask that you be that kind of operator.
VERY IMPORTANT
DO NOT ALLOW ANYONE TO PLAY ON OR AROUND GRAIN WAGON.
IF ENTRANCE INTO GRAVITY BOX IS NECESSARY, USE EXTREME CAUTION. IF GRAVITY
BOX CONTAINS GRAIN OR OTHER MATERIALS, ENTRAPMENT IN SUCH MATERIALS MAY
CAUSE INJURY, SUFFOCATION, OR POSSIBLE LOSS OF LIFE.
DO NOT OVERLOAD GRAVITY BOX OR ADD MORE SIDE EXTENSIONS THAN WHAT IS
RECOMMENDED.
MAKE SURE A SLOW MOVING VEHICLE EMBLEM IS INSTALLED ON THE REAR OF THE
GRAIN WAGON.
TAKE THE TIME TO HOOK -UP YOUR LIGHTS.
UNIT IS TO BE TOWED AT TRACTOR SPEEDS ONLY - 25 MPH MAXIMUM.
PERSONAL INJURY AND DAMAGE TO UNIT MAY RESULT IF OVERRIDING STEERING
STOPS.

IMPORTANT
Replace lost, damaged, painted, or unreadable decals
immediately. If parts that have decals are replaced, also make
sure to install new decals. These decalsinform andremind the
operator with operational information and safety messages.

IMPORTANT CHECK POINTS
1. Check all wheel nuts for tightness before first load. Failure to do so may damage wheel
seats. Once seats are damaged, it will become impossible to keep nuts tight. Torque
to 400 Ft. Lbs. (dry). Re-tighten after first load and check periodically afterward.
2. Check toe-in. Improper toe
will cause excessive tire wear.
Toe should be set at 1/16 per
side. To adjust toe, set turn-
ing assembly perpendicular to
front axle. Then use straight
edge or sight front tire straight
with rear tire. Once straight,
turn 1/16". Tighten locknuts.
3. Grease all lube points daily during busy season:
A. 2 on each front spindle pivot
B. 4 on turning assembly pivot
C. 1 on each tie rod end
D. 2 on tongue on telescope latch plate.
MAINTENANCE AND SERVICING INFORMATION
4. Tire pressure: All truck tires..........Approximately 65 Lbs.
5. Wheel hubs (check grease after first season of use.)
Note: The bearings are pressure packed with grease. An empty hub cavity
does not indicate a lack of grease. It is not beneficial to fill the cavity.
6. Maintain brake fluid level in master cylinder. Lubricate push pipe and guides to ensure
free movement. Adjust brake shoes as necessary: Rotate wheel for forward movement
only. Turn cog until shoes drag, turn back cog 1-1/2 turns (20 cogs). See "Brake
System" for detailed instructions.
7. When hauling corrosive materials such as fertilizers, it is advisable after use to wash out
all excess materials to prevent premature rusting.

•IMPORTANT
It is extremely important that the spindles are never welded to by the customer.
Special manufacturing processes are utilized at the factory, and spindle weldments should
always be replaced if repairs are necessary.
TIRES
Any questions or needs concerning
new tire performance should be
directed to your local tire dealer. Used
tires carry no warranty.

TONGUE AND WHEEL ALIGNMENT
1. Use a straight edge or string to set front tires straight with rear tires.
2. Loosen right and left tie rod clamps.
3. Adjust distances "L" from the hitch pin to the right and left king pins equal on each side
until tonque is perpendicular to front axle.
4. Again check that front and rear wheels are in a straight line. Set 1/16" Toe-In at front
of each wheel. Tighten tie rod clamps.
5. Check tracking of wagon.
Please refer to the following information for specific tongue/wheel alignment. If the
tongue does not pull perpendicular to the front axle, the grain wagon can "dog-track".

ADJUSTABLE CHUTE
220937
Your grain wagon is equipped with an adjustable unloading chute-height feature. The
adjustment bolt is located under the door area of the grain wagon. When the bolt is turned
in (clockwise), the chute unload height decreases. When the bolt is turned out (counter-
clockwise), the chute height is raised.
Therightand left sideboardsand center bracketare pre-assembled. An end board (frontor rear)
is banded to the assembly with foam protection. The banded assemblies are stored on the front
and rear angle brackets on each side of the box. Three bolts hold each assembly in place. The
center bracket is bolted to the brace tube angle bracket (see inset).
IMPORTANT: AT LEAST TWO INDIVIDUALS ARE REQUIRED TO ERECT THE SIDE BOARDS.
To erect the side boards, remove three fasteners (each side) and cut the banding. Turn front and
rear boards into position and install fasteners but do not tighten. Tilt side assemblies into position
and install fasteners. Install the angle braces and cross brace if applicable. The fasteners
supplied are 3/8 x 3/4 flange screws and flange nuts. NOTE: Have a longer capscrew on hand if
required for seating the boards initially. After all boards are in position, tighten fasteners.

SLIDING HITCH AND LATCH
The braking system on your running gear is designed to release automatically when
you back up. Before adjusting individual brake shoes, inspect the master cylinder
push pipe and push tube for proper contact when the sliding hitch and latch
mechanism is pulled forward. Note: A minimum 1/4" gap is necessary to prevent
possible "dragging" of brakes.
Check the push pipe for alignment and lubricate to ensure free movement in the
tongue bracket. Lubricate guides on bottom of cover. The master cylinder "L"
bracket should be 3/16" above the tongue bracket sides. To prevent possible
interference, do not overtighten cover capscrew.
MASTER CYLINDER
Brake fluid level may be checked by removing cap on master cylinder. Refill level
with a heavy-duty brake fluid that meets or exceeds DOT-3. Do not clean any brake
components in gasoline, kerosene, or oil.

BRAKE SHOE ADJUSTMENT
NOTE: Be sure to read preceding section on sliding hitch and latch adjustment
before proceeding to this step.
Brakes are set at factory, however, it may become necessary to adjust shoes after
the first season. The brakes incorporate a "Back-up" feature that makes it necessary
to rotate the wheels in the direction of forward rotation only when making adjust-
ments. Jack up each wheel, turn adjustment cog wheel located in slot on the brake
backing plate until brake shoes drag, then turn back cog wheel approximately
1-1/2 turns (20 cogs).
BRAKE BLEEDING
Use ONLY quality DOT-3 heavy-duty brake fluid.
If pressure bleeding equipment is available, follow the manufacturer's instructions in
bleeding the system.
MANUAL BLEEDING:
Fill master cylinder with fluid. Bleed rear brakes first (farthest from master cylinder).
Loosen the bleeder screw located in wheel cylinder one turn. The system is now
open to the atmosphere through a passage drilled in the screw. Securely install
bleeder hose to bleed screw on first wheel cylinder to be bled.
Submerge the loose end of bleeder hose in a glass container filled approximately
1/3 full with brake fluid to observe expelled air bubbles while stroking master cylinder.
NOTE: The bleed hose must have a snug connection at bleed screw and remain
submerged in brake fluid to avoid re-entry of air into the system.
Position a flat tool bar between master cylinder "L" bracket and housing (see
illustration) and pump master cylinder with long steady strokes. Continue to stroke
master cylinder until bubbles stop rising to surface of fluid in glass jar. Remove hose
and re-tighten bleeder screw
Repeat bleeding operation at each wheel cylinder. During the bleeding process,
replenish the brake fluid, so the level does not fall below the 1/2 full level in the
master cylinder reservoir. After bleeding is completed, make sure master cylinder
reservoir is filled and filler cap is securely in place.
WARNING
Saltwater, granular fertilizers and other corrosive materials are destructive to metal.
To prolong the life of a braking system used under corrosive conditions, flush the
actuator periodically with a high pressure water hose. Be sure to re-grease bearings
and oil all moving parts after the unit has dried. At the end of the season, when unit
is to be stored, remove the brake drums and clean inside the brakes. Pack wheel
bearings before drum is installed. CAUTION: Do not pack hub full of grease.
Excessive grease may leak into brake drums causing brake failure.
