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 the hydraulic system of all pressure before adjusting or servicing. See hydraulic
power unit manual for procedure to relieve pressure.
• High-pressure uids can penetrate the skin and cause serious injury or
death. Use cardboard or wood to detect leaks in the hydraulic system.
Seek medical treatment immediately if injured by high-pressure uids.
• 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 res, 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.
- Outer covering chafed/cut or wire reinforcing exposed.
- Outer covering ballooning locally.
- Evidence of kinking or crushing of the flexible part of a hose.
• Comply with all laws governing highway safety when moving machinery.
• Use transport lights as required by all laws to adequately warn operators of other vehicles.
• Use good judgment when transporting equipment on highways. Regulate speed to road
conditions and maintain complete control.
• Maximum transport speed of this implement should never exceed 20 mph as indicated
on the machine. Maximum transport speed of any combination of implements must not
exceed the lowest specied speed of the implements in combination. Do not exceed 10
mph during off-highway travel.
• Slow down before making sharp turns to avoid tipping. Drive slowly over rough ground
and side slopes.
• It is probable that this implement is taller, wider, and longer than the towing vehicle. Be-
come aware of and avoid all obstacles and hazards in the travel path of the equipment,
such as power lines, ditches, etc.
