Additional safety rules for drill presses

WARNING. For your own safety, do not try to use your

drill press or plug it in until it is completely assembled and
installed according to the instructions and until you have
read and understood the following:

1. Your drill press must be bolted securely to a workbench.
In addition, if there is any tendency for your drill press to
move during certain operations, bolt the workbench to
the floor.

2. This drill press is intended for use in dry conditions and
indoor use only.

3. Always wear safety goggles which comply to a
recognised standard. Use a face or dust mask along
with safety goggles if the drilling operation is dusty. Use
ear protectors, especially during extended periods of
operation.

4. Do not try to drill material too small to be securely held.
Do not drill material that does not have a flat surface
unless it is clamped securely.

5. Always keep hands out of the path of the drill bit. Avoid
awkward hand positions where a sudden slip could cause
your hand to move into the drill bit.

6. Do not install or use any drill bit that exceeds 175mm (7
inches) in length or extends more than 150mm (6 inches)
below the chuck jaws. They can suddenly bend outwards
or break.

7. Do not use wire wheels, router bits, shaper cutters, circle
(fly) cutters or rotary planers on this drill press.

8. When cutting a large piece of material make sure it is
fully supported at the table height.

9. Do not perform any operation freehand. Always hold the
workpiece firmly against the table so it will not rock or
twist. Use clamps or a vice for unstable workpieces.

10. Make sure there are no nails or foreign objects in the

part of the workpiece to be drilled.

11. Whenever possible, position the workpiece to contact

the left side of the column; if it is too short or the table is
tilted, clamp solidly to the table.

12. If the workpiece overhangs the table such that it will fall

or tip if not held, clamp it to the table or provide auxiliary
support.

13. Set the drill press to a speed appropriate to the job.

14. Do not start the drill press while the drill bit is touching

the workpiece.

15. When using a drill press vice, always fasten it to the

table.

6

16. Make sure all clamps and locks are firmly tightened
before drilling.

17. Securely lock the head and table support to the column,
and the table to the table support before operating your
drill press.

18. Never turn your drill press on before clearing the table of
all objects (tools, scraps of wood etc.)

19. Before starting the operation, jog the motor switch to
make sure the drill bit does not wobble or vibrate.

20. Let the spindle reach full speed before starting to drill. If
your drill press makes an unfamiliar noise or if it vibrated
excessively, stop immediately, turn the drill press off and
unplug it. Do not restart until the problem is corrected.

21. Do not perform layout assembly or setup work on the
table while the drill press is in operation.

22. Do not exceed the rpm stated on the bit or accessory.
See the instructions that come with the accessory.

23. When drilling large diameter holes, clamp the workpiece
firmly to the table. Otherwise, the bit may grab and spin
the workpiece at high speed. Do not use fly cutters or
multiple-part cutters, as they can come apart or become
unbalanced in use.

24. Make sure the spindle has come to a complete stop
before touching the workpiece.

25. To avoid injury from accidental starting, always turn the
switch off and unplug the drill press before installing
or removing any accessory attachment or making any
adjustment.

Insert the drill bit required for the application.
Mark the drilling points on the work piece.
Where possible secure the workpiece in position with vice

or clamps.
Turn on the drill press using the on/off switch.
Rotate the feed wheel to bring the drill bit down to the

workpiece.

13

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,

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.
