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.
• Never attempt to operate implement unless you are in driver’s seat.
• Never enter a cart containing grain. Flowing grain traps and suffocates
victims in seconds.
Brent 678/678XL — Safety
1-5
• 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.
• Secure drawbar pin with safety lock and lock tractor drawbar in fixed position.
Before Servicing
Before Operating
• Avoid working under an implement; however, if it becomes absolutely
unavoidable, make sure the implement is safely blocked.
• Ensure that all applicable safety decals are installed and legible.
• To prevent personal injury or death, always ensure that there are people who remain out-
side the cart to assist the person working inside, and that all safe workplace practices
are followed. There is restricted mobility and limited exit paths when working inside the
implement.
• Secure drawbar pin with safety lock and lock tractor drawbar in xed position.
• 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.
Brent 678/678XL — Safety
1-6
• 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.
During Operation
Before Transporting
• Secure transport chain to towing vehicle before transporting. DO NOT transport without
chain.
• 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 machine. Make sure the SMV emblem is visible to approach-
ing traffic.
• This implement may not be equipped with brakes. Ensure that the towing vehicle has
adequate weight and braking capacity to tow this unit.
Brent 678/678XL — Safety
1-7
During Transport
• 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 speed of implement should never exceed 20 mph. 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.
• Do not transport grain cart on roads while loaded.
• It is probable that this implement is taller, wider and longer than the towing vehicle.
Become aware of and avoid all obstacles and hazards in the travel path of the equip-
ment, such as power lines, ditches, etc.

Driveline Safety
• Do not allow children near equipment that is running or engaged.
• Do not exceed 1000 rpm PTO speed.
• Disengage the PTO, stop the tractor engine, and remove key from ignition before making
inspections, or performing maintenance and repairs.
• Inspect the driveline, quick disconnect, overload shear-bolt limiter or clutch, and shield-
ing often. Repair immediately. Use replacement parts and attaching hardware equivalent
to the original equipment. Only alterations described in this manual for overall length
adjustment are allowed. Any other alteration is prohibited.
• Avoid excessively long hardware or exposed and protruding parts which can snag and
cause entanglement.
• Lubricate the driveline as recommended in the MAINTENANCE section.
• Keep hoses, wiring, ropes, etc. from dangling too close to the driveline.
• Install driveline and shields according to recommended lengths and attaching methods
with recommended hardware. The driveline shield should rotate independently a full rota-
tion and telescope freely. The retaining chain must be secured to the implement safety
shield.
• Adjust drawbar to height recommended in tractor set up section.
• Be careful not to hit the driveline with tractor tires when turning.
• Check the length of the telescoping members to insure the driveline will not bottom out
or separate when turning and/or going over rough terrain.
• Proper extended and collapsed lengths of the telescoping PTO shaft must be verified
before first operation with each and every tractor. If the extended length of the PTO
shaft is insufficient, it may become uncoupled during operation and cause serious injury
or death from contact with uncontrolled flailing of PTO shaft assembly components.

Pressurized Oil
• Relieve pressure before disconnecting hydraulic lines from tractor, loosening any hydraulic
ttings or servicing hydraulic system. 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-pres-
sure 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.
Brent 678/678XL — Safety
1-10
• Keep a rst aid kit and properly rated re extinguisher nearby.
• Keep emergency numbers for fire, rescue, and poison control personnel
near the phone.
Preparing for Emergencies
Wearing Protective Equipment
• Wear clothing and personal protective equipment appropriate for the
job.
• Wear steel-toed shoes when operating.
• Wear hearing protection when exposed to loud noises.
• Do not wear additional hearing impairing devices such as radio headphones, etc.
