OPERATING INSTRUCTIONS
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.
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:
Dry bits and wet bits. This machine should only be used with dry bits.
DRY DRILLING
Dry drilling is a different process from wet drilling.
When dry drilling, you must not push too hard. Allow the tool to work at its own pace.
Dry drilling is normally done in softer materials. Note that in very hard materials it may not be possible to drill
dry.
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.
