Masonry drilling

•

For maximum performance use tungsten carbide-tipped

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.

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.
