Operating & Safety Guide 527
Begin carefully, allowing the steel to mark the surface,
this will stop the steel from wandering over the work
surface and causing unnecessary and expensive damage.
Never apply too much pressure, let the breaker/steel
work at its own pace.
Lift it clear before turning OFF, and wait for moving parts
to stop before putting it aside.
If the steel becomes jammed in the work DO NOT use
the breaker as a lever. Tease the steel from the work
by pushing then pulling.
If the steel strikes a hidden object, stop the breaker
immediately then check to make sure it is safe to
continue.
Where possible, concentrate on weak spots in the
structure you are breaking - mortar joints, cracks etc.
Alternatively, start close to an edge and gradually
work inward.
Take your time, rushing a job tends to produce poor results
and increases the risk of a serious accident.
Don’t over do it - you are more likely to have an accident if
you are suffering from fatigue.
Never push the breaker beyond its capabilities. If it will
not do the job you want with reasonable ease, change it for
a more powerful model.
Regularly check that the air vents in the breakers
body are clear. If these become blocked with dust, isolate
the unit from its power supply. Clean them out using a soft
brush before continuing, taking care not to push dirt into
the drill body.
Avoid hitting or dropping the breaker. Its casing will be
damaged by a heavy blow.
When not in use, store the equipment somewhere
clean, dry and safe from thieves.
Remove the steel and clean up the breaker ready
for return.
Neatly coil the flex and place on the transport trolley
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.
This equipment has been designed to be used by an
able bodied adult. If you suffer from either a
temporary or permanent disability, you must seek
expert advice before using this equipment.
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 that, 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 parts,
tie back long hair.
Always switch OFF the equipment when not in use.
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.
Never lift or pull the equipment by its power
supply cable.
Make sure you know how to switch this
machine OFF before you switch it ON, in case you get
into difficulty.
Take special care when breaking into floors, they may
contain hidden pipework, reinforcing bars or electrical
cables. If in doubt, hire a Cable Avoiding Tool or metal
locater, to determine the exact position of such hazards.
Stop the machine if you experience discomfort or numbness
during use.
Watch your footing. Take special care if working other
than on firm, level ground.
Most HSS Breakers plug into a standard 240v 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 becomes
damaged, return it. Never try to repair it yourself.
Keep flexes out of harm’s way, and clear of the
work area.
ELECTRICAL SAFETY
GENERAL SAFETY 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.
Ensure the breaker and power socket are switched
OFF before plugging into the power supply.
Fit the breaker with a point, chisel or tarmac cutter as
appropriate. Our staff will advise you on the best tool for
the job.
To fit the steel, cock the chuck lever into the open
position, push in the steel as far as it will go, then snap
the lever back to lock it.
Take care, never force the steel in. If the fit is at all tight,
return the equipment to us.
Plug the machine
into its power
supply and switch
the supply ON.
To start the breaker,
depress the ON/OFF
lever, to stop simply
release the lever.
Hold the breaker
with 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
breaker’s flex over
one shoulder to
keep it clear of the
steel, but make sure
there is still enough
slack so you are not
restricted in movement.
On first contact with the surface, the breaker/steel
will try to wander off line. Take great care until you
become familiar with the tool.
