Refer also to Safety Messages and Operation Instructions in each of the appropriate sections of the Power Unit and Minicor-3. Pay close attention to the Safety Signs affixed to the Power Unit and the Minicor-3.
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.

Park in level area. Do not allow riders on the minicor-3 or power unit at any time. There is no safe place for any riders. Disengage hydraulic power and place transmission into neutral before attempting to start engine.

Be careful when changing directions on slopes. Do not start or stop suddenly on slopes. Avoid operation on steep slopes. Before leaving the operator's area for any reason – lower the minicor-3 to the ground, stop the power unit engine, set the brakes and remove the key from the ignition.
Use extreme care and maintain minimum ground speed when transporting on hillside. Be careful when turning sharp corners. Never allow riders on either power unit or minicor-3. Falling off can kill. Be a safe and courteous driver. Always yield to oncoming traffic in all situations, including narrow bridges, intersections, etc.
Remove hydraulic pressure prior to doing any maintenance. Place the minicor-3 on the ground or securely blocked up, and turn off the engine. With the engine off and the key in the ACC position toggle hydraulic flow controls on and off to release the pressure in the lines.

When working on or around the minicor-3, lower it to the ground or secure it with transport chains. Periodically tighten all bolts, nuts and screws and check that all cotter pins are properly installed to ensure unit is in a safe condition.
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.

572-6666 (toll free), or via email to info@utilicor.ca. For safety reasons, this entire Operations Manual should be reviewed prior to operation of the Utilicor Rotary Coring Unit. Failure to review the entire manual prior to commencing operations, or to follow warnings and operating procedures outlined in this manual, may result in damage to the equipment, injury, or possibly death.
A valid driver’s license for the appropriate class or level of motor vehicle or piece of equipment being operated. • Successful completion of a practical, on-site training program and operating examination for the Utilicor equipment, administered by a qualified trainer. • First Aid and CPR training.
Circle-Check Safe and reliable operation of any piece of equipment starts with a comprehensive and thorough pre-trip and post trip procedure. Walk around (circle-check) the Utilicor coring equipment to ensure that the unit is safe to operate. Pre-Trip Inspection The following is a suggestion of some important elements of a pre-trip procedure.
Utilicor Process, Pilot Bit and Integral Center Pilot Hole The central pilot bit and related pilot hole, are unique to the Utilicor process, and perform four important functions in Rotary Coring and Reinstatement (1) Accuracy: The 2 3/8" PDC central pilot bit, which is integral to the Utilicor coring process, acts as a concentric guide for the coring drum, centering and stabilizing it to ensure a fast and accurate cut.
(2) Before the coring process begins, manipulate the tilt controls on the skid-steer to make sure the minicor-3 is level and flush to the ground. (3) Ensure that the appropriate rate of water is flowing through the pilot bit and the adapter plate inside the drum.

This will result in blown seals on the hydraulic motors. (3) If there is any back pressure in the hydraulic system on the minicor-3™ or skid-steer, engaging the quick connect hydraulic couplers may be difficult. Refer to the operation manual of your skid-steer to determine how to de-energize the hydraulic pressure in the auxiliary lines.
Slowly lower the front of the attachment until it is level to the horizon.

(5) Turn on water pump switch on minicor-3™, establish and adjust flow rate of water to cutting drum and pilot bit assembly. → (6) Open the Water Petcock (1/8 turn) → (7) Turn the cutter ON. In the event an emergency or hydraulic failure push the Estop in and all flow will be diverted back to the skid-steer.

(19) Engage Spring Lock (20) Using the Skid steer lift the minicor-3 off the ground to a safe transport height and move skid-steer and the coring attachment away from cut core. Lift the core out using core puller. Relocate the core to safe place for reinstatement later.
Step 4: Detach minicor-3™ (1) Disconnect 12 volt connection. (2) Relieve pressure in the skid-steer’s hydraulic system. (Consult skid- steer operations manual). The hydraulic hoses attached to the skid- steer should go limp. (Failing to do this will make it virtually impossible to reconnect the couplings.)
70° F. Colder temperatures will result in proportionately longer setting times, and higher temperatures will reduce setting times. Contact Utilicor for cold weather reinstatement procedures. (9) To achieve even coverage of the Utilibond™ around the entire core, using the core puller, rock the core back and forth and from side to side until Utilibond™...
(4) It is important to run the entire system with the glycol mixture before storing the minicor-3, or moving a significant distance during the day. Wind chill factors can greatly reduce effective temperatures and increase the likelihood of freezing, so take this into account when performing the winterizing procedures.

(6) Inspect all water fittings / control valves for condition. Repair or replace as required. (7) Keep the minicor-3™ clean. A clean piece of equipment is easier to maintain, easier to inspect for overall condition, will perform better and be safer to operate.
Important: Refer to the owner’s manual of the skid-steer on which your minicor-3™ is attached to. For all service and maintenance related questions. This Utilicor Operations manual is not a substitution or replacement for original equipment service manuals.
