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!

• 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.
Following Safety Instructions
• To avoid possible injury, lower implements to the ground before servicing.
• 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.
• When working around the implement, be careful not to be cut by sharp edges.
Before Servicing
• Do not stand between tractor and implement during hitching.
• When working around the implement, be careful not to be cut by sharp edges.
• Always make certain everyone and everything is clear of the machine before beginning
operation.
• Inspect elds for buried utility lines (electric, natural gas, water, etc.). Contact local
authorities to find buried lines at 1-888-258-0808.
Before Operating
1-5
SubTiller II — Safety
• Do not allow anyone to ride on the equipment. Never dismount from
moving vehicle. Severe injury or death can occur from being run over by
the equipment.
• 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.
• Do not attempt to move any objects away from moving parts.
• Avoid personal attire such as loose tting clothing, shoestrings, drawstrings, pants cuffs,
long hair, etc. that may become entangled in moving parts.
• Use extreme care when operating close to ditches, fences, or on hillsides.
• Do not leave towing vehicle unattended with engine running.
During Operation
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.

• Keep a rst aid kit and properly rated re extinguisher nearby.
• Keep emergency numbers for re, rescue, and poison control personnel
near the phone.
• 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.
