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.

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.

IMPORTANT SAFETY INFORMATION
Preparation
1. Never use the machine until you have read and completely understand this manual, the Excavator tractor
Operator's Manual and each of the Safety Messages found on the safety signs on the Excavator tractor
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 tractors, 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.

OPERATION
High Attention!
A case drain line (3rd hose line--3/8'') is required to be added prior to use of this attachment. The case drain
line will relieve the excess pressure and drain it back to your return line, then into the reservoir. Without a
case drain line installed properly, that extra pressure will blow a seal or damage your hydraulic line.
Mounting coupler
A case drain line
(3/8'') must be
added prior to use!

Bolt Torque
CHECKING BOLT TORQUE
The tables shown below give correct torque values for various bolts and cap screws. Tighten all bolts to the
torques specified in chart unless otherwise noted. Check tightness of bolts periodically, using bolt torque
chart as a guide. Replace hardware with the same strength bolt.
Torque figures indicated above are valid for non-greased or non-oiled threads and heads unless otherwise
specified. Therefore, do not grease or oil bolts or cap screws unless otherwise specified in this manual.
When using locking elements, increase torque values by 5%.
