Apply pressure to the feed wheel and slowly drill through the workpiece. Don’t force the drill, allow the drill bit to do the work.

After drilling the hole release the feed wheel and allow the spindle to return to its original position.

Turn off the drill press.

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 and repair

Repairs

Only an authorised service centre should replace the cordset or effect other repairs. If the cordset is damaged or worn, have it repaired or replaced by an authorised service centre.

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.

Cleaning

Keep the tool’s air vents unclogged and clean at all times.

Remove dust and dirt regularly. Cleaning is best done with a soft brush or a rag.

Re-lubricate all moving parts at regular intervals.

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.

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.
