to test. Press the “Reset” button to energize the circuit to the machine.
WARNING! 110V UK machines are not equipped with a PRCD portable residual current device or GFCI
ground fault circuit interrupter. The machine must always be used with an isolating transformer for
protection in case an electrical fault should occur.
WARNING: Always connect the plug into the wall socket with a drip loop. If the cable leads downward
directly into the wall socket, any water on the cable could run into the socket, causing a hazard.
ASSEMBLY
Thread the water supply assy. Into the hole in the bottom of gearbox and tighten with a wrench.

OPERATING INSTRUCTIONS
1) MOUNTING THE CORE BIT
CAUTION: Ensure that the threads of the spindle and the core bit match. Attempting to mount
mismatched threads will result in damage to both threads.
The spindle has two types of threads. The outside male thread is 1-1/4inch UNC, the inside female thread is 1/2
inch BSP. Ensure both the core bit and the machine spindle are clean. Any debris could cause excessive run-out
of the mounted core bit. Excessive run-out can cause premature failure of the core bit and/or a safety hazard.
Tighten the bit to the spindle using two wrenches. Only use correct sized wrenches to avoid damage to the
spindle or bit. Torque to at least 200 newton meters
Choosing the correct core bit for the job:
Ensure that the bit you are using is suitable for the material you are drilling. There are two main types of
diamond core bit:
Wet/dry type-electroplated (surface set) diamond core bits and wet type-sintered (impregnated)
diamond core bits.
We recommend always using wet-type (sintered) bits with this machine.
Electroplated bits, also known as wet/dry type, are only suitable for less hard materials. The diamonds are sharp
and coarse and are only set on the surface. They have a much shorter service life than sintered bits and cannot
be dressed (resharpened). Once they become dull, they must be replaced. They tend to work well with softer,
abrasive materials like brick.
