Directions For Use
1. ALWAYS drill a 8mm pilot hole before attempting to use the hole saw .
2. Assemble the hole saw as directed on the previous page.
3. Insert assembled hole saw into the drill chuck and tighten securely.
4. Set the drill to a reasonably slow speed, plug in and switch ON.
5. Slowly offer the pilot drill into pre-drilled hole, use steady pressure to push the hole saw into the surface of the material.
DO NOT FORCE the drill, allow the drill to do the work.
It may be necessary to adjust the speed of the drill to suit the size of the hole saw being used.
6. To ensure the hole saw doesn’t bind, occasionally withdraw it from the hole whilst it is still turning to clear any waste, keep
repeating this process until the hole is finished.
7. When finished turn the drill OFF and unplug from the main electric supply.
!!! CAUTION !!!
When using hole saws, make sure that you have a firm grip at all times to prevent the drill being snatched from your hands in
the event of a jam. Jamming can be caused for various reasons, such as small pieces of material breaking off and wedging
the hole saw in the hole.
