General-purpose drill suitable for
drilling into all types of masonry,
metal and timber and for most DIY
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.

For advice on the safety and suitability of this
equipment contact your local HSS Hire Shop.
Keep children, animals and bystanders away from
the work area.
Never use this equipment if you are ill, feeling
tired, or under the influence of alcohol or drugs.
This equipment should only be used by a
competent person who has read and understood
these instructions.
Safety Goggles MUST be worn by everyone in
the work area.
Some materials contain substances which,
when inhaled, can be harmful to health. A
suitable mask must be worn when using this
equipment.
This equipment generates potentially harmful
noise levels. To comply with health and safety at
work regulations, ear defenders must be worn by
everyone in the vicinity.
Wear practical, protective clothing, gloves and
footwear. Avoid loose garments and jewellery that
could catch in moving arts, tie back long hair.
Never use the equipment if highly flammable
vapours – petrol or paint thinner fumes for example –
are present.
Always switch OFF and unplug the equipment
when not in use.
Take special care when changing drill bits – they
are sharp.
Always unplug the tool before making adjustments
to it. Check that it is switched OFF and that you have
removed the chuck key before plugging it back in.
Having switched OFF, always wait for the drill bit to
come to rest before putting the tool down.
Check the condition of the equipment before use.
If it shows signs of damage or excessive wear, return it to
your local HSS Hire Shop.
Make sure you know how to switch this machine OFF
before you switch it ON, in case you get into difficulty.
Think twice before locking the ON/OFF trigger in
the ON position using any trigger lock button fitted.
Only change the gear/speed and/or direction of rotation
when the machine is stopped.
Take special care when drilling into walls or floors,
they may contain hidden pipework, reinforcing
bars or electrical cables. If in doubt, hire a Cable
Avoiding Tool or metal locator, to determine the exact
position of such hazards.
GENERAL SAFETY Watch your footing. Take special care if working other
than on firm, level ground. Above ground-level, work
from a stable, purpose-made work platform such as
a step-up or trestle.
Most HSS Percussion drills plug into a standard
13amp power socket. However, 110V models (with
a round yellow plug) must be provided with a
suitable 110V generated supply, or powered from
the mains via a suitable 110V transformer.
If the equipment fails, or if its flex or plug gets
damaged, return it. Never try to repair it yourself.
Keep flexes out of harm’s way, and clear of moving parts.
Extension leads should be fully unwound and
loosely coiled, away from the equipment. Never run
them through water, over sharp edges or where they
could trip someone.
Keep the equipment dry, using electrical equipment in
very damp or wet conditions can be dangerous.
To reduce the risk of electric shock, use a
suitable RCD (Residual Current-Operated Device)
available from your local HSS Hire Shop, or power the
equipment from a mains circuit with a built-in RCD.
Never carry or pull the equipment by its flex.
Ensure the equipment and power socket are
switched OFF before plugging into the
power supply.
Some models will be supplied in a carrying case and
you may find that the side handle will need to be
fitted, simply slide the handle assembly over he
drills body, then secure in place by either twisting
the handle clockwise or by tightening the wing nut.
NOTE The side handle MUST be fitted and used, if
the bit jams during drilling the side handle will help
restrain the machine. Without the handle fitted you risk
breaking your wrist.
Fit the drill with the right bit for the job.
Open and close the chuck with the chuck
key provided.
Drill Bits
TCT drills. General purpose masonry drill bits are
available with straight-shank or SDS fitting.
HSS (high speed steel). Used mainly for drilling holes
in steel but also used for wood and plastics.
Flat (spade) bits. Designed for use in timber products.
GETTING STARTED
ELECTRICAL SAFETY
If the depth stop is to be used, this may be set either by
releasing the wing nut holding it in place or by twisting
the forward handgrip to loosen/tighten the depth
rod’s guide.
The machine offers a choice of settings, select the
correct speed for the job. As a rule of thumb, the
harder the material and/or the larger the hole, the
slower the drill speed.
On most models, there is a sliding speed selection switch
on the side of the tool body.
If drilling into masonry, set the drill to ‘hammer’.
Depending on which model you have, the hammer
action is turned on and off with a sliding switch or
control knob.
If drilling into timber, metal or plastic turn the
selector to drill only.
Plug the machine into its power supply and switch
the supply ON.
To start the drill, squeeze in the ON/OFF trigger, to
stop simply release the trigger. For safety reasons you are
advised not to use the trigger lock.
