SAFETY INSTRUCTIONS
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.
Replace any CAUTION, WARNING, DANGER or instruction safety sign that
is not readable or is missing. 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 machinery
and trained in this equipment’s operations.
Do not allow persons to operate or install 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 prime mover 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

PREPARATION
Never operate the power unit and minicor-3 until you have read and
completely understand this manual, the Power Unit Operator’s Manual, and
each of the Safety Messages found on the safety signs on the prime mover
and minicor-3. Only fully trained operators or trainee operators under the
close supervision of a fully trained person should use this machine.
Personal protection equipment including hard hat, safety glasses, sturdy
rough-soled 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. Always wear relatively tight and belted clothing to avoid
entanglement in moving parts.
PROLONGED EXPOSURE TO LOUD NOISE MAY CAUSE PERMANENT
HEARING LOSS!
Power units with or without implements 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 engines, chain saws, radios, and
other such sources close to the ear) is cumulative over a lifetime without
hope of natural recovery.
Operate the minicor only with a power unit Rated for 1500 pounds.
Minicor-3 operating power is supplied from the prime mover hydraulic
system. Refer to your prime mover manual for hydraulic engagement and
disengagement instructions. Know how to stop prime mover and minicor-3
quickly in case of an emergency. When engaging hydraulic system, the
engine RPM should always be low.
Personal protection equipment including safety glasses, safety shoes, and
gloves are recommended during assembly, installation, operation,
adjustment, maintaining, repairing, removal, or moving the attachment.

Introduction
Utilicor Technologies Inc. (Utilicor)
Utilicor is the exclusive manufacturer and distributor of a field-proven,
keyhole coring and pavement reinstatement system. Our mission is to
develop new, innovative and cost effective technologies for the utility
industry.
Utilicor Process
The Utilicor process, referred to as "Utilicoring", combines the purpose-built,
field proven, truck or minicor-3™ skid-steer mounted, Utilicor Rotary Coring
Unit with Utilibond™, a proprietary bonding compound, that have been
specially engineered for coring and the permanent reinstatement of the cored
coupon in asphalt, asphalt-concrete, concrete and reinforced concrete road
surfaces, and concrete sidewalks. The process has been approved as a
permanent pavement repair by several transportation authorities in both
Canada and the USA since 1992, on thousands of keyhole excavations, with
ZERO failures.
Utilibond™, our proprietary core bonding compound is an integral part of the
reinstatement process and has been independently tested and shown to
create a bond (in less than 30 minutes at 70ºF) that is stronger than the
original pavement and can support the combined weight of five transit buses
in under half an hour.
The Purpose of The Operations Manual
This manual is intended as a reference guide for operating and maintaining
the Utilicor coring equipment and performing core reinstatements using
Utilibond™. It is designed to familiarize the operator with the main elements
of the process, and to answer common questions, but does not replace
comprehensive, on-the-job training performed by a competent trainer. Neither
should it be considered as a replacement for common sense or a substitute
for the maintenance requirements of the vehicle or equipment on which your
Utilicor unit has been installed or mounted. Most importantly, this operations
manual is intended to be used in conjunction with the internal policies,
procedures and maintenance schedules already established by your
company, and does not supersede them.
