Never push the equipment beyond its design
limits. If it will not do what you want with reasonable
ease and speed, assume you have the wrong tool for the
job. Contact your local HSS Hire Shop for advice.
Handle the equipment with care. Avoid dropping it,
knocking it, or otherwise exposing it to damage.
Keep the equipment clean - you will find this less of a
chore if you clean it regularly, rather than wait until the
end of the hire period.
When not in use, store the equipment somewhere
clean, dry and safe from thieves.
FINISHING OFF
Switch OFF and unplug all electrical equipment
connected to the transformer. Switch OFF the
power supply to the transformer, then unplug or, if
required, have a qualified electrician disconnect
the unit.
Give the unit a final clean up 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.
There is a serious risk of personal injury if you do
not follow all instructions laid down in this guide.
The hirer has a responsibility to ensure that all
necessary risk assessments have been completed
prior to the use of this equipment.
This equipment should only be used by an
operator who has been deemed competent to do
so by his/her employer.
This equipment should be used by an able bodied,
competent adult who has read and understood these
instructions. Anyone with either a temporary or permanent
disability, should seek expert advice before using it.
Keep children, animals and bystanders away from
the work area. Cordon off a NO GO area using either
cones, barriers or tape, available for hire from your local
HSS Hire Shop.
Never use this equipment if you are ill,
feeling tired, or under the influence of
alcohol or drugs.
Take care as 3kVA continuous, 5kVA and 10kVA
transformers are heavy (between 42kg and 95kg),
never attempt to lift one on your own, always get help.
Never lift or move a transformer by its power
supply cable.
Always switch OFF and unplug equipment when
not in use.
Ensure the work area is well lit and ventilated, if in
doubt, ask about lighting and ventilation equipment at
your local HSS Hire Shop.
Make sure that everyone is warned of what you
are doing.
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.
GENERAL SAFETY
ELECTRICAL SAFETY
16A 110V
Socket
All HSS transformers must be connected to a
suitable 230V supply. Those rated to 3kVA can simply
be plugged into a standard 13amp power socket.
Transformers rated above 3kVA must be wired
directly into a suitable mains circuit by a qualified
electrician. You must only use a 30A circuit for
transformers rated between 3kVA and 5kVA and a 60A
circuit for those rated above 5kVA.
Never interfere with any plugs or sockets fitted to
the transformer.
Handle plugs and leads with care. Never run cables
through water or over sharp edges. Never run them
where they are likely to trip someone over.
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.
Never carry or pull the equipment by its power
supply cable.
If the equipment fails, or if a plug or lead gets
damaged, return it. Never attempt to repair it yourself.
Never overload the electrics. Add up the power
ratings of all the equipment connected to the
transformer and check that the total is less than the
power rating of the transformer itself. Remember that
1kVA = 1kW = 1000 W.
Always switch OFF and unplug electrical
equipment before attempting to maintain or
adjust it in any way. Never leave electrical tools
unattended while they are plugged in and switched ON.
GETTING STARTED

Position the transformer in a safe place, as close to
its power supply as possible.
Do not site the transformer on surfaces, which are
easily scratched, stained or damaged by heat.
Either plug it in or have a qualified electrician
connect it to a suitable supply.
Never connect a transformer to its power supply
via an extension lead, though you can, of course,
plug extension leads into the transformers’ socket outlets.
Make sure the total supply required does not
exceed the capacity of the transformers’ Socket. A
16amp 110V socket can supply up to 1700W and a
32amp, up to 3500W.
HSS transformers are either tool rated or
continuous rated.
If tool rated, you can power equipment up to its
total rate for a maximum of 30 minutes, after which
the transformer will need to cool. If you continue to use
it at full rate, the internal coils will overheat and the
transformer may be permanently damaged.
If you need to use the ‘tool rated’ unit
continuously, the maximum power available will
be 70% of its kVA rating.
E.G.; 2kVA tool rated transformer can supply a
maximum of 1400W of power continuously.
Where a transformer is rated as continuous, that
rating is its maximum.
E.G.: 3kVA Continuous rated transformer can
supply a maximum of 3000W of power
continuously. HOWEVER, this does not mean that you
can expect a greater amount of power in short bursts.
Using an RCD ADAPTOR...
Fit 110V RCDs to the transformer’s 110V outlet
sockets.
Some models are fitted with Micro Circuit Breakers
(MCB’s). If the power stops, check the MCB first. Switch
OFF the supply, reset the MCB, then switch the power
ON.
Safety Cut Outs
All HSS Transformers are protected by thermal
disrupters, circuit breakers, or fuses, and comply
with either British Standard BS3535 or
International Standard CEE 15. Their output
sockets comply with British Standard BS4343 and
International Standard CEE 17.
If the transformer’s thermal disruptor trips, allow
the unit to cool before resetting. To reset simply
press the reset button (see illustration).
