Carriage Rigidity

Shear Pin and Clutch Protection

Mounting Bits

Drilling Procedure

It is essential that the carraige fits snugly on the column to prevent the motor or bit from wobbling during drilling. Through normal use the carraige may loosen from the column and begin to wobble. Before drilling, always make sure the carraige is rigid by trying to wiggle it with your hand. If the carraige is secure it should not move. If it does move, tighten the adjustment screws for the nylon gibs that secure the carraige to the column.

Tighten only enough to remove the play. Do not over tighten.

The MK-Manta I Core Drill uses either a shear pin or a friction clutch to protect the gear and motor against overload. The shear pin drives the outer portion of the drive spindle. If the motor should overload the pin will shear. Extra shear pins are supplied or can be ordered from MK Diamond’s Customer Service. Tighten only enough to remove the play. Do not over tighten. Another model features a friction clutch rather than a shear pin to protect the motor and gears. If the motor overloads the clutch will begin to slip and the bit will stop rotating. The clutch is factory-set and does not require adjustments. However, under normal use, the clutch may start to slip at low torque. If this happens, refer to the motors Owner’s Manual.

Bits with permanently attached adapters simply screw directly onto the threads of the drill spindle. Ensure that the end of the bit butts up squarely against the shoulder on the spindle.

The MK-Manta I has a 1 1/4”-7 thread. For bits with other threads, use a shaft coupling. After a bit has been mounted, turn the power on and check that there is a minimum of run-out or wobble.

!WARNING

To reduce the risk of injury, always unplug tool before attaching or removing accessories. Only use specifically recommended accessories. Others may be hazardous.

!WARNING

When drilling through concrete floors, the core will generally drop from the diamond bit. Caution should be provided for people and property below the drilling area.

1.Ensure that you have read and fully understand the complete operation of the MK-Manta I you have purchased prior to commencing drilling operations.

2.Select and install a diamond core bit appropriate for the job. Note: Grease the bit threads to help prevent the bit from seizing on the spindle due to rust.

3.Select either high or low gear speed according to the chart in the Drilling Speeds section of this manual. (Do not shift speed when motor is on.)

4.Connect water hose to water swivel.

5.Secure the rig as described in the Securing the rig section of this manual.
