SAFETY INSTRUCTIONS (continued)ADJUSTABLE MANUAL BASE
EQUIPMENT SAFETY GUIDELINES
Safety of the operator is one of the main concerns in designing and developing a new piece of equipment.
Designers and manufacturers build in as many safety features as possible. However, every year many
accidents occur which could have been avoided by a few seconds of thought and a more careful approach to
handling equipment.You, the operator, can avoid many accidents by observing the following precautions in this
section. To avoid personal injury, study the following precautions and insist those working with you, or for you,
follow them.
In order to provide a better view, certain photographs or illustrations in this manual may show an assembly with
a safety shield removed. However, equipment should never be operated in this condition. Keep all shields in
place. If shield removal becomes necessary for repairs, replace the shield prior to use.
Replace any CAUTION, WARNING, DANGER or instruction safety sign that is not readable or is missing.
Location of such safety signs is indicated in this booklet.
Never use alcoholic beverages or drugs which can hinder alertness or coordination while operating this
equipment. Consult your doctor about operating this machine while taking prescription medications.
Review the safety instructions with all users annually.
This equipment is dangerous to children and persons unfamiliar with its operation. The operator should be a
responsible adult familiar with farm machinery and trained in this equipment’s operations. Do not allow per-
sons to operate or assemble this unit until they have read this manual and have developed a thorough
understanding of the safety precautions and of how it works.
To prevent injury or death, use a tractor equipped with a Roll-Over Protective System (ROPS). Do not paint
over, remove or deface any safety signs or warning signs on your equipment. Observe all safety signs and
practice the instruction on them.
Never exceed the limits of a piece of machinery. If its ability to do a job, or to do so safely, is in question - DON’T
TRY IT.
Do not modify the equipment in any way. Unauthorized modification may impair the function and/or safety and
could affect the life of the equipment.
In addition to the design and configuration of this implement, including Safety Signs and Safety Equipment,
hazard control and accident prevention are dependent upon the awareness, concern, prudence, and proper
training of personnel involved in the operation, transport, maintenance, and storage of the machine. Refer also
to Safety Messages and Operation Instructions in each of the appropriate sections of the Tractor and Post
Driver Manuals. Pay close attention to the Safety Signs affixed to the Tractor and the Post Driver.
SAFETY INSTRUCTIONS (continued)
SAFETY SIGNS
Keep safety signs clean and legible at all times.
Replace safety signs that are missing or have become illegible.
Replaced parts that displayed a safety sign should also display the current sign.
Safety signs are available from your Distributor or Dealer Parts Department or the factory.
How to Install Safety Signs:
• Be sure that the installation area is clean and dry.
• Be sure temperature is above 50°F (10°C).
• Decide on the exact position before you remove the backing paper.
• Remove the smallest portion of the split backing paper.
• Align the sign over the specified area and carefully press the small portion with the exposed sticky backing in place.
• Slowly peel back the remaining paper and carefully smooth the remaining portion of the sign in place.
• Small air pockets can be pierced with a pin and smoothed out using the piece of sign backing paper.
PREPARATION
Never operate the tractor and post driver until you have read and completely understand this manual, the Tractor
Operator’s Manual, and each of the Safety Messages found on the safety signs on the tractor and post driver.
Personal protection equipment including hard hat, safety glasses, safety shoes, and gloves are recommended
during assembly, installation, operation, adjustment, maintaining, repairing, removal, or moving the implement.
Do not allow long hair, loose fitting clothing or jewelry to be around moving parts.
PROLONGED EXPOSURE TO LOUD NOISE MAY CAUSE PERMANENT HEARING LOSS!
Tractors with or without attachments can often be noisy enough to cause permanent, partial hearing loss. We
recommend that you wear hearing protection on a full-time basis if the noise in the Operator’s position exceeds
80db. Noise over 85db on a long-term basis can cause severe hearing loss. Noise over 90db adjacent to the
Operator over a long-term basis may cause permanent, total hearing loss. NOTE: Hearing loss from loud noise
(from tractors, chain saws, radios, and other such sources close to the ear) is cumulative over a lifetime without hope of natural recovery.
Ensure post driver is properly mounted, adjusted and in good operating condition.

SAFETY INSTRUCTIONS (continued)HYDRAULIC CONTROL VALVE &
Please remember it is important that you read and heed the safety signs on the post driver, and the safety rules
set forth. Clean or replace all safety signs if they cannot be clearly read and understood. They are there for
your safety as well as the safety of others. The safe use of this machine is strictly up to you, the operator.
All things with moving parts are potentially hazardous. There is no substitute for a cautious, safe-minded
operator who recognizes potential hazards and follows reasonable safety practices. The manufacturer has
designed this driver to be used with all its safety equipment properly attached, to minimize the chance of
accidents. Study this manual to make sure you have all safety equipment attached.
Make sure that all operating and service personnel know that in the event hydraulic fluid penetrates the skin,
it must be surgically removed within a few hours by a doctor familiar with this form of injury, or gangrene may
result.
If a safety shield or guard is removed for any reason, it must be replaced before the machine is again operated.
Before servicing the machine, engage the parking brake or place the transmission in “Park”, shut off the tractor and remove the key. Relieve all hydraulic pressure in lines.
When the use of hand tools is required to perform any part of assembly, installation, adjustment, maintaining,
repairing, removal, or moving the driver, be sure the tools used are designed and recommended by the tool
manufacturer for that specific task.
Personal protection equipment including hard hat, safety glasses, safety shoes, and gloves are recommended
during assembly, installation, operation, adjustment, maintaining, repairing, removal, or moving the driver. Do
not allow long hair, loose fitting clothing or jewelry to be around moving parts.
Always use two people to handle heavy, unwieldy components during assembly, installation, removal, or
moving the driver.
Never place any part of your body where it would be in danger if movement should occur during assembly,
installation, operation, maintaining, repairing, removal, or moving the driver.
Never place yourself between the tractor and post driver while implement is in operation.
Do not walk or work under a raised driver ram unless it is securely blocked or held in position. Do not depend
on the tractor hydraulic system to hold the driver ram in place.
Never leave post driver ram in the raised position. Always lower ram to the ground or to the transport position
and install the transport lock pin before transporting or storing.
A heavy load can cause instability of the tractor. Use extreme care during travel. Slow down on turns and
watch out for bumps. The tractor may need front counter-weights to counter-balance the weight of the driver.
Do not allow riders on the driver or tractor at any time. There is no safe place for any riders.
SAFETY INSTRUCTIONS (continued)
Before you operate the driver, check over all pins, bolts and connections to be sure all are securely in place.
Replace any damaged or worn parts immediately.

swinging side to side. Adjust as tightly as practical for best performance.
Clear the work area of objects which might cause operator to trip or fall.
Do not operate post driver on steep hillsides. When installing posts on uneven or hilly terrain, position the
tractor with the post driver uphill. This way if any movement of the tractor should occur, it will be away from the
post driver operator.
Never position the post by hand. Always use Post Holder Tool.
Watch out for low overhead electrical wires and limbs when operating or transporting the post driver. Check
clearance of doorways when entering a building.
Be sure post is cut “SQUARE” on top. Angle cut post can “KICK OUT” of driver and injure the operator.
Install transport lock pin and pin clip before transporting or storing the post driver. NEVER INSERT FINGER
IN TRANSPORT PIN HOLE TO CHECK ALIGNMENT. Finger could be sheared off if driving ram moves.
Keep hands, feet, hair, jewelry, and clothing, away from all moving parts.
Do not operate the Post Driver without all safety shields and guards in place.
When using a unit, a minimum 20% of tractor and equipment weight must be on tractor front wheels. Without
this weight, tractor could tip over, causing personal injury or death. The weight may be attained with a front end
loader, front wheel weights, ballast in tires of front tractor weights. When attaining a minimum 20% of tractor
and equipment weight on the front wheels, you must not exceed the ROPS weight certification. Weigh the
tractor and equipment. Do not guess or estimate!
Only use a tractor equipped with a ROPS cab or rollover protective structure. Keep foldable ROPS systems
in “locked up” position at all times. Keep seat belt fastened.
ALWAYS OBEY SAFETY WARNINGS!
