Equipment Safety Guidelines
1. Safety of the operator and bystanders is one of the main concerns in designing and developing equipment.
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 or death, study the following precautions
and insist those working with you, or for you to follow them.
2. 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 used in this condition. Keep all shields in
place. If shield removal becomes necessary for repairs, replace the shield prior to use.
3. Replace any safety sign or instruction sign that is not readable or is missing. Location of such safety signs is
indicated in this manual.
4. Never use alcoholic beverages or drugs which can hinder alertness or coordination while using this
equipment. Consult your doctor about using this machine while taking prescription medications.
5. Under no circumstances should young children be allowed to work with this equipment. Do not allow persons
to use 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. Review the safety instructions with all users annually.
6. This equipment is dangerous to children and persons unfamiliar with its operation. The operator should be a
responsible, properly trained and physically able person familiar with machinery and trained in this
equipment's operations. If the elderly are assisting with work, their physical limitations need to be recognized
and accommodated.
7. 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.
8. Do not modify the equipment in any way. Unauthorized modification may result in serious injury or death and
may impair the function and life of the equipment.

IMPORTANT SAFETY INFORMATION
Safety Training
1. Safety is a primary concern in the design and manufacture of our products. Unfortunately, our efforts to
provide safe equipment can be wiped out by a single careless act of an operator or bystander.
2. In addition to the design and configuration of 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 this equipment.
3. It has been said, "The best safety feature is an informed, careful operator." We ask you to be that kind of an
operator. It is the operator's responsibility to read and understand ALL Safety and Using instructions in the
manual and to follow these. Accidents can be avoided.
4. the machine. If this machine is used by any person other than yourself, or is loaned or rented, it is the
machine owner's responsibility to make certain that the operator, prior to using:

IMPORTANT SAFETY INFORMATION
Preparation
1. Never use the machine until you have read and completely understand this manual, the skid steer
Operator's Manual and each of the Safety Messages found on the safety signs on the skid steer and
machine.
2. Personal protection equipment including hard hat, safety glasses, safety shoes, and gloves are
recommended during assembly, installation, operation, adjustment, maintaining, repairing, removal,
cleaning, or moving the unit. Do not allow long hair, loose fitting clothing or jewelry to be around
equipment.
3. PROLONGED EXPOSURE TO LOUD NOISE MAY CAUSE PERMANENT HEARING LOSS!
Power equipment with or without equipment attached 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 skid steer, chain saws, radios, and other such
sources close to the ear) is cumulative over a lifetime without hope of natural recovery.
4. Clear working area of stones, branches or hidden obstacles that might be hooked or snagged, causing
injury or damage.
5. Use only in daylight or good artificial light.
6. Be sure machine is properly mounted, adjusted and in good operating condition.
7. Ensure that all safety shielding, and safety signs are properly installed and in good condition.

IMPORTANT SAFETY INFORMATION
Hydraulic Safety
1. Make sure that all the components in the hydraulic system are kept in good condition and are clean.
2. Before applying pressure to the system, make sure all components are tight, and that lines, hoses and
couplings are not damaged.
3. Do not attempt any makeshift repairs to the hydraulic lines, fittings, or hoses by using tapes, clamps or
cements. The hydraulic system operates under extremely high pressure. Such repairs will fail suddenly and
create a hazardous and unsafe condition.
4. Wear proper hand and eye protection when searching for a high-pressure hydraulic leak. Use a piece of
wood or cardboard as a backstop instead of hands to isolate and identify a leak.
5. If injured by a concentrated high-pressure stream of hydraulic fluid, seek medical attention immediately.
Serious infection or toxic reaction can develop from hydraulic fluid piercing the skin surface.
6. Relieve pressure on hydraulic system before maintaining or working on system.

OPERATION
HYDRAULIC CONNECTIONS & MOUNTING
The machine is shipped from the factory in a basic, universal configuration that allows it to be mounted to
any model skid steer. However, the skid steer must be equipped with a remote hydraulic outlet on the front of
the cab frame.
The Hydraulic Rotary Tiller should always be located on a level, dry area that is free of debris and other
foreign objects. When attaching The Hydraulic Rotary Tiller to a skid steer, follow this procedure:
1. Make sure that all bystanders, especially small children are clear of the work area.
2. Make sure there is enough room and clearance to safely drive up to The Hydraulic Rotary Tiller.
3. Drive up to The Hydraulic Rotary Tiller while aligning the mounting components, and hook up into the mount.
4. Secure the mounting:
a. Drive into the mounting frame.
b. Seat the top of the face plate into the frame of The Hydraulic Rotary Tiller.
c. Raise the loader and tilt the face plate until it is fully mated.
5. Engage the lock pins to secure The Hydraulic Rotary Tiller to the loader.
6. Connect the hydraulics:
7. Use a clean rag or paper towel to clean the dirt from the couplers on the hose ends of the skid steer.
a. Connect the hoses to the skid steer couplers. Be sure the couplers are securely seated.
b. Route and secure the hoses along the frame with clips, tape or plastic ties to prevent binding and
pinching. Be sure to provide slack for tilting.
8. Raise The Hydraulic Rotary Tiller.
