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.

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 type diamond core bits and wet type-sintered (impregnated) diamond core bits.
This machine should only use Dry type bits:
Dry type core bits are suitable for less hard materials. They tend to work well with softer, abrasive materials like brick. Only dry type bits are suitable for use with soft percussion function.
Water should always be used to cool and lubricate the bit and to flush out abrasive particles formed while
SPECIAL INSTRUCTIONS FOR DRY DRILLING: (Dry drilling models only)
Dry drilling is a different process from wet drilling. It is more of a cutting process and you must use a much lighter touch.
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.
