Slowly turn the orbital control wheel clockwise to engage the
pavement with the pilot bit and begin the coring process. Slowly turn
the wheel keeping the drum feed gauge to a
maximum of 750 PSI
.
Too much down pressure will stop the drum and result in the hydraulic
system going to bypass or begin to lift the unit off the ground. If this
occurs, back the drum up and resume cutting.
Follow the “Tips for a Successful Coring Operation”.

Once the slurry changes color, and the resistance on the orbital control
is reduced, the core should be detached from the pavement and you
are finished cutting. Before moving the minicor-2 verify that the core
has been cut all the way through the pavement.
(11)
Raise Drum, turning the control orbital counter clockwise until the
drum is raised to its maximum height. Using the Skid steer lift the
minicor-2 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.
CAUTION:
Some cores are
VERY HEAVY.
Depending on diameter,
composition and thickness, cores can weigh more than 200 lbs. Small cores
weighting less than 80 lbs. (18” in diameter and under 6” deep) can be moved
by one individual. Cores weighing up to 160 lbs. (18” in diameter between 6”-
10” deep) can be lifted by two men using a spud bar through the eye of the
core-puller. Heavier cores should be lifted and positioned with the assistance
of a core lifting device. Cores can also be carefully tipped on their side and
rolled to the side of the roadway.
