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.
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).
