Step 3.
1. Turn on Coolant Water
2. Open Water Petcock. From horizontal or 3 o’clock (OFF) upward to 2 o’clock
3. Verify that water is flowing out through the Pilot Bit. The water flow will need to be
adjusted during the coring operation. Adjust flow so that the slurry created is dense
but flowing.

ATTENTION
The coring process requires water to cool the core drum and the pilot bit. Make
sure the water tank is full before you begin the coring operation. The process uses
approximately 1 gallon of water per inch depth cut.

Step 4. Begin to Cut
1. Turn on the coring drum by moving the Drum Speed Lever up to the right. Using an
RPM reader set the speed according to the size of drum you are using.
Recomended Core Bit Speeds
8 inch diameter Core Bit 250-270 RPM
10 inch diameter Core Bit 230-250 RPM
12 inch diameter Core Bit 210-230 RPM
18 inch diameter Core Bit 190-210 RPM
2. Begin to lower coring assembly by turning the Steering Orbital clockwise until the
Pilot Bit engages the surface.
3. When the coring drum contacts the substrate use Auxiliary Water Hose to cool the
drum until it has fully seated in the pavement.
4. Continue coring keeping the Core Rotational pressure between 500 and 750 PSI. Too
much down pressure will cause the core drum to lift the MC450. This may result in
damage to the equipment.
The coring process varies depending on the substrates you are cutting through. For best
results, slow and steady feed works best. If the down pressure is too high, the pressure will
begin to lift the MC450 off the ground and change the coring angle. Should this occur back
off the steering orbital until the MC450 settles back on its base. Then continue the coring.

5. Continue coring and watch for signs that you have completed your cut.
a, The cutting pitch (sound) changes.
b. The slurry changes color.
c. The gauge rotational pressure spikes then drops down.
6. If you encouter an issue hit the E-Stop button and that will divert all hydraulic flow directly
back to Tank.
7. When you think you have completed your cut, raise the coring assembly all the way up.
(Turn steering Orbital counter-clockwise)
8. Shut off Coring Drum when the drum clears the substrate
9. Close Water Petcock and turn off Coolant Water Pump.
10.Insert a screw driver or small pry-bar in the Kerf and gently apply force. If the core moves
you have successfully cut the core and you can move the MC450 to the next cut location.
NOTE: If the core does not move, continue with the coring process.
11. Engage Lock Down Latch before moving attachment.
12.Insert the core puller into the Core and remove the core. Set aside the core.
Do not move the equipment until you are sure that the core is loose. It is very
difficult to reposition the MC450 over a partially cut core!
