9. BASIC OPERATION

Warning!

● Dust and swarf

– A correctly fitted dust mask, suitable for the

activity and in accordance to the relevant

standard must be worn.

– Swarf produced by metal drilling is extremely

sharp. Take precautions when clearing swarf.

The burr left on the hole is also sharp and

should be removed with a suitable tool.

● Before drilling check that there are no hidden

hazards such as electrical cables, water or

gas pipes running below the surface by

use of a metal/voltage detector.

● Always wear safety goggles.

● Drill bit will be hot after use.

● Do not expose either the drill or charger to

rain or water.

● Do not overcharge the battery pack (more than

six hours) as this could damage the battery

cells.

9.6 DRILLING WOOD AND

PLASTIC – FIG.10

To prevent splitting around the drill holes on the reverse side, clamp a piece of scrap timber

under the material to be drilled.

9.7 DRILLING METAL – FIG.11

Metals such as mild steel, aluminium and brass may be drilled.

– Mark the point to be drilled with a centre punch

– A drop of oil

on the drilled area will aid cutting and help prolong the life of the bit.

Note: Although metal drilling is technically within the capabilities of this drill, its rotational speed is

not always fast enough to achieve perfect results every time. For this reason, extra caution should

always be taken when drilling metal, as snagging of the drill may occur.
