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!

Pressurized Oil
• Relieve pressure before disconnecting hydraulic lines from tractor, loosening any hydraulic fittings or
servicing hydraulic system. See hydraulic power unit manual for procedure to relieve pressure.
• Use a piece of cardboard or wood to detect leaks of hydraulic fluid under pressure. Correct hydraulic leaks immediately.
• High-pressure fluids can penetrate the skin and cause serious injury or death. Seek medical treatment
immediately if injured by high-pressure fluids.
• Hydraulic system must be purged of air before operating to prevent serious injury or death.
• Do not bend or strike high-pressure lines. Do not install bent or damaged tubes or hoses.
• Repair all oil leaks. Leaks can cause fires, personal injury, and environmental damage.
• Route hoses and lines carefully to prevent premature failure due to kinking and rubbing against other parts. Make sure that
all clamps, guards and shields are installed correctly.
• Check hydraulic hoses and tubes carefully. Replace components as necessary if any of the following conditions are
found:
- End fittings damaged, displaced, or leaking.

Important Check Points
Tires and Wheels
1. Check tire pressures and maintain at recommended values listed in this manual.
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 the torque of the wheel nuts/bolts.
• IMPROPERLY TORQUED WHEEL NUTS/BOLTS CAN CAUSE A LOSS OF IMPLEMENT CONTROL
AND MACHINE DAMAGE. WHEEL NUTS/BOLTS MUST BE CHECKED REGULARLY. SEE
TORQUE PAGE IN THE "MAINTENANCE" SECTION FOR PROPER WHEEL NUT/BOLT SPECI-
FICATIONS. WARRANTY DOES NOT COVER FAILURES CAUSE BY IMPROPERLY TORQUED
WHEEL NUTS/BOLTS.
3. Grease all lube points daily during busy season:
A. 1 on each front spindle pivot
B. 3 on turning assembly pivot
C. 1 on each tie rod end
D. 2 on tongue on telescope latch plate.
E. 4 on Rear Axle rotation points

Important Check Points (continued)
4. Check the oil level of the wheel hubs. Set the wagon with
each axle level side to side. Check the oil level at the
clear window of each hub end. The oil level should be at
the indicator ring slightly below the fill plug. To add oil -
remove the center plug and fill with 80W90 gear lube up to
the indicator ring. Check the oil level before any extended
or seasonal use.
5. 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. 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” 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.

Important Check Points (continued)
Tongue and Wheel Alignment
Please refer to the following information for specific tongue/wheel alignment. If the tongue does not pull perpen-
dicular 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.
