Switch off impact or hammer drill. • Avoid shock / impacts on the carbide tips. This leads to small carbide splinters which results to severe loss in performance • Do not tilt the hole saw in the hole • Remove the drill core after each operation. Do the same with chips and sawdust. • The 68 mm hole saws with rim countersink may not be stopped before it is removed • Advance with care to prevent the cut edges tearing. 11 Index 10 9 OIL 8 7 6 5 4 3 2 1
