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!

Following Safety Instructions
• Read and understand this operator’s manual before operating.
• All machinery should be operated only by trained and authorized personnel.
• To prevent machine damage, use only attachments and service parts approved by the
manufacturer.
• Always shut tractor engine off and remove key before servicing.
• Avoid personal attire such as loose tting clothing, shoestrings, drawstrings, pants cuffs,
long hair, etc., that may become entangled in moving parts.
• Do not allow anyone to ride on the implement. Make sure everyone is clear
before operating machine or towing vehicle.
• When working around sweeps and points, be careful not to be cut by sharp
edges.
• Never attempt to operate implement unless you are in driver's seat.
• Avoid working under an implement; however, if it becomes absolutely un-
avoidable, make sure the implement is safely blocked.
• Ensure that all applicable safety decals are installed and legible.
• When working around the implement, be careful not to be cut by sharp edges.
• Explosive separation of a tire and rim can cause serious injury or death. Only properly
trained personnel should attempt to service a tire and wheel assembly.
• Add sufcient ballast to tractor to maintain steering and braking control at all times. Do
not exceed tractor's lift capacity or ballast capacity.
Before Servicing
RIPPER-ROLLER — Safety
1-5
During Operation
• Regulate speed to eld conditions. Maintain complete control at all times.
• Never service or lubricate equipment when in operation.
• Keep away from overhead power lines. Electrical shock can cause serious injury or
death.
• Use extreme care when operating close to ditches, fences, or on hillsides.
• Do not leave towing vehicle unattended with engine running.
• Do not stand between towing vehicle and implement during hitching.
• Always make certain everyone and everything is clear of the machine before beginning
operation.
• Verify that all safety shields are in place and properly secured.
• Ensure that all applicable safety decals are installed and legible.
• Add sufcient ballast to tractor to maintain steering and braking control at all times. Do
not exceed tractor's lift capacity or ballast capacity.
• Inspect elds for buried utility lines (electric, natural gas, water, etc.). To nd buried lines
in the US or Canada contact 1-888-258-0808, in the US you may also contact 811.

Before Transporting
During Transport
• Secure transport chains to towing vehicle before transporting. DO NOT transport without
chains.
• Install transport locks before transporting.
• Check for proper function of all available transport lights. Make sure that all reectors
are clean and in place on the machine. Make sure the SMV emblem is visible to ap-
proaching traffic.
• This implement may not be equipped with brakes. Ensure that the towing vehicle has
adequate weight and braking capacity to tow this unit.
• Comply with all laws governing highway safety when moving machinery.
• Use transport lights as required by all laws to adequately warn operators of other ve-
hicles.
• 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.

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.
