masonry impact bits when drilling holes in brick, tile,
concrete, etc.

Move drilling/hammer 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.
Note. 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.
