Recommendations for Tool Operation
• When drilling, always apply pressure in a straight line with
the bit, but do not push hard enough to stall the motor or
deflect thebit. A smooth even flow of material indicates the
proper drillingrate.
• Your hammer can be used for dry diamond drilling into
masonry up to 100 mm. For diamond drilling above this
diameter in masonry and regular large diameter diamond
drilling in masonry and concrete, we advise the use of
a dedicated diamond core drill. Follow the core bit or
manufacturer’s recommendations for using the accessory.
NOTE: Always use core bits with integral centredrill systems
and ensure the RPM (speed) of the hammer does not
exceed the maximum rated RPM of the diamondcore.
- Insert the centredrill into its holder in the centre of the
corebit.
- Remove and unplug themachine.
- Remove the centredrill from itsholder.
- Plug the machine in and insert the core bit into
theworkpiece.
