Masonry drilling
•For maximum performance use tungsten
•Move drilling mode selector to hammer mode 
.
•Apply light pressure and medium speed for best results in brick.
•Apply additional pressure and high speed for hard materials such as concrete.
•When drilling in tile, practice on a scrap piece to determine the best speed and pressure.
Cleaning
1.Keep your machine and its cord clean. The outside of the machine can be cleaned using a damp soft cloth with a mild detergent if required.
2.Some maintenance products and solvents may damage the plastic parts; these include products containing benzene, trichloroethylene, chloride and ammonia.
3.Excessive sparking generally indicates the presence of dirt in the motor or abnormal wear on the carbon brushes.
4.Take special care to keep the ventilation inlets/outlets free from obstruction; cleaning with a soft brush followed by a compressed air jet will usually be sufficient to ensure acceptable internal cleanliness.
5.Wear eye protection when carrying out cleaning.
CAUTION. Do not use cleaning agents to clean the plastic parts of the drill.
Power cord maintenance
If the supply cord needs replacing, the task must be carried out by the manufacturer, the manufacturer’s agent, or an authorised service centre in order to avoid a safety hazard.
