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.
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 bits (Always use water with wet bits)
-Dry bits
2) WATER SUPPLY
Water is a basic requirement for diamond core drilling. The water serves as a
coolant to avoid the working surface at the tip of the bit from overheating.
To connect the water supply. Attach the quick-release water coupling to a
water hose.
WARNING: Check all connections of the water feed system to ensure
there are no leaks. Inspect hoses and other critical parts which could
deteriorate.
WARNING: The maximum water pressure should not exceed 70 psi (4 bar).
Use a water collector with a wet vacuum to collect cooling water if nearby objects could be damaged by water.
WARNING: Never allow water to enter the motor. A perfectly functioning water collector set up must be
used for any drilling performed at an upward angle.
3) SELECTING SPEEDS
There are 2 speed ranges to suit the bit size and work piece hardness.
CAUTION: Never attempt to change gears on a running machine! Only
adjust when the machine is at rest.
Select the desired gear range by pressing the release button and then turning
the gear selector either clockwise or counterclockwise into the desired gear. It
will usually be necessary to turn the spindle by hand a little to get it to shift all
the way.
