Wood drilling
• For maximum performance, use high speed steel bits
for wood drilling.
• Secure the workpiece to prevent it from turning
when drilling.
• 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.
Metal drilling
• For maximum performance, use high speed steel bits for
metal or steel drilling.
• Use a centre punch to mark the hole location on the
workpiece.
• 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.
Maintenance
WARNING. Always ensure that the tool is switched off and
the plug is removed from the power point before making
and adjustments or maintenance procedures.
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.
Cleaning
1. Keep the tool’s air vents unclogged and clean at all times.
2. Remove dust and dirt regularly. Cleaning is best done
with a soft brush or a rag.
3. Re-lubricate all moving parts at regular intervals.
4. Never use caustic agents to clean plastic parts.
CAUTION. Do not use cleaning agents to clean the plastic
parts of the tool. A mild detergent on a damp cloth is
recommended.
General inspection
Regularly check that all the fixing screws are tight. They
may vibrate loose over time.
