General-purpose drill suitable for

jobs around the house.
Operating & Safety Guide 523
Hold the tool in both hands and adopt a stable
stance that gives a good view of the work
while
keeping you clear of the bit.
Do not work in areas where you are forced
to stand on loose debris or on a slippery
uneven surface.
If possible,
drape the tool’s flex over one shoulder to
keep it clear of the bit, but make sure there is still
enough slack
so you are not restricted in movement.
Start drilling slowly
and carefully, then, once the hole
is established,
concentrate on drilling in a straight
line –
with the drill at right angles to the surface,
where appropriate.
Apply just enough pressure to achieve a steady
rate of penetration –
too much or too little pressure
will overheat and/or blunt the drill bit and could damage
the electric motor.
When drilling into
hard material such as
masonry,
withdraw the bit from time to time,
keeping the drill
running, in order
to cool the bit
and the drill’s motor.
This will also clear waste from the hole.
When drilling large diameter holes with TCT or HSS twist
bits, drill a small pilot hole first, then drill again with a
larger bit, until the correct size is achieved.
If using a flat blade for timber, do not use a pilot as the
flat bit relies on its own pilot tip to keep the blade central.
If you wish
to use the drill as an electric screwdriver,
use an adaptor to hold the various driver tips.
But
be warned, some models don’t have reverse so once the
screw is in place you may have to remove it manually!.
Never push the drill beyond its natural capabilities.
If it won’t do the job you want with reasonable ease,
change it for a more powerful model.
Never let the drill bit or motor over-heat.
Stop
work at frequent intervals and run the drill for a
minute or so, just holding it in your hands. The air
drawn in and around it will cool everything down and
prevent damage.
Regularly check that the air vents in the drill body
are clear.
If these become blocked with dust, clean them
out using a soft brush before continuing, taking care not
to push dirt into the drill body.
Avoid over-tightening the drill chuck
when securing
a bit, and
never attempt to fit a bit, larger than the
recommended chuck capacity.
When not in use, store the equipment somewhere
clean, dry and safe
from thieves.
EQUIPMENT CARE
Remove all drill bits and clean up
the drill ready
for return.
Check that the drill still has its chuck key, neatly
coil the flex and place in the carrying case ready
for return to your local HSS Hire Shop.
