General Hazard Information
No accident-prevention program can be successful without the wholehearted cooperation of
the person who is directly responsible for the operation of the equipment.
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 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.
REMEMBER:
THINK SAFETY
A CAREFUL OPERATOR IS THE
BEST INSURANCE AGAINST AN
ACCIDENT!

oTorque wheel nuts and check tire pressure as specified in MAINTENANCE section.
oTires are inflated to specified air pressure, located in the MAINTENANCE section.
oCheck to be sure all safety decals are correctly located and legible. Replace if damaged.
oCheck to be sure all reflective decals are correctly located.
oCheck to be sure SMV emblem and SIS decals are in place. See “SMV Emblem & SIS Decals” in SET
UP section.
oCheck to be sure transport lights are working properly.
oTransport chain is properly installed and hardware is torqued to specification.
oPaint all parts scratched in shipment.

705 GRAIN WAGON — Set Up
Before the wagon is used the reflective surface
of the SMV must face rearward. This may re-
quire removal of film protecting the reflective
surface or removing and reinstallation of the
SMV. When reinstalling the SMV make sure
that it is mounted with the wide part of the
SMV at the bottom.
The SIS decals (one on the front and one on
the rear of the wagon) may require removal of
film protecting the decals.

Important Check Points
Tires and Wheels
1. Check tire pressures and maintain at recommended values listed in this manual.
• IMPROPERLY TORQUED WHEEL NUTS/BOLTS CAN CAUSE A LOSS OF IMPLEMENT
CONTROLANDMACHINEDAMAGE.WHEELNUTS/BOLTSMUSTBECHECKEDREGU-
LARLY. SEE TORQUE PAGE IN THE MAINTENANCE SECTION FOR PROPER WHEEL
NUT/BOLT SPECIFICATIONS. WARRANTY DOES NOT COVER FAILURES CAUSED BY
IMPROPERLY TORQUED NUTS/BOLTS.
For questions regarding new tire warranty, please contact your local original equipment tire
dealer. Used tires carry no warranty. Tire manufacturers’ phone numbers and web sites are
listed in this manual for your convenience.
2. Check toe-in. Improper toe will cause exces-
sive tire wear. Toe should be set at 1/16 per
side. To adjust toe, set turning assembly per-
pendicular 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.
TIRES
For questions regard-
ing new tire warranty,
please contact your
local original equip-
ment tire dealer. Used
tires carry no warranty.
See "Tire Warranty"
in the MAINTENANCE
section.

Important Check Points (continued)
4. 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.
5. Maintain brake fluid level in master cylinder. Lubricate push pipe and guides to ensure free move-
ment. Adjust brake shoes as necessary: Rotate wheel for forward movement only. Tighten adjusting
cog nut until you cannot rotate wheel by hand, then back off the adjustment until 3 - 4 threads are
showing. And then additional threads may be necessary. See “Brake System” in this section for
detailed instructions.
6. When hauling corrosive materials such as fertilizers, it is advisable after use to wash out all excess
materials to prevent premature rusting.
• 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.

2-6
Tongue and Wheel Alignment
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”.
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 tongue
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.
