Points to bear in mind when drilling in metal
• Mark the position of the hole and make a dimple with a centre punch.
• The tool may overheat if you use the wrong speed. It is a good idea to use
a coolant suitable for your material, eg methylated spirits for aluminium
(cast iron and brass must be drilled dry).
• Use the lowest gear and low speed for large holes.
• Take extra care when clamping thin or sharp metal objects so that they do not
come loose and cause cut injuries when drilling. Use a vice if possible.
Points to bear in mind when drilling in concrete, tile or brick
• Use carbide-tipped drills!
• Use the hammer drill setting and press carefully, with the same feed rate all the time.
• The drilled-out material is in the form of powder or dust. Use a dust mask.
• Use the hammer drill setting and press carefully, with the same feed rate all the time.
DO NOT
use hammer drilling on tiles.
Care and maintenance
• Check before using the drill that all its screws are tight. The machine is subject to
severe vibration during hammer drilling.
• Make sure that all the cooling air openings of the machine are clear and open.
• If necessary, clean them with a cloth moistened with a mild detergent.
Never use solvents or strong cleaning agents.
• Keep the user guide together with the hammer drill.
