Wood Drilling
• For maximum performance, use high speed steel bits for
wood drilling.
• Move drilling/hammer mode selector to drilling mode .
• Secure the workpiece to prevent it from turning when
drilling.
• Begin drilling at a very low speed to prevent the bit
from slipping off the starting point. Increase the speed
as the drill bit bites into the material.
• When drilling through holes, place a block of wood
behind the workpiece to prevent ragged or splintered
edges on the back side of the hole.
• Do not lock the trigger in the ‘on’ position when the
drill may need to be stopped suddenly.
Metal drilling
• For maximum performance, use high speed steel bits for
metal or steel drilling.
• Move drilling/hammer mode selector to drilling mode .
• Use a centre punch to mark the hole location on
the workpiece.
• Begin drilling at a very low speed to prevent the bit
from slipping off the starting point.
• Maintain a speed and pressure which allows cutting
without overheating the bit. Applying too much
pressure will:
Overheat the drill
Wear the bearings
Bend or burn bits
Produce off-centre or irregular shaped holes
• When drilling large holes in metal it is recommended to
drill with a small bit at first, then finish with a larger
bit. Also, lubricate the bit with oil to improve drilling
action and increase bit life.
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.
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.
