HSS Hire HW890 Operating & Safety Manual

EQUIPMENT CARE

Never push the equipment beyond its design limits. If
it will not do what you want assume you have the wrong
type or size of cable for the job. Ask at your local HSS Hire

Weld Depot for advice.
Keep the equipment clean. You will find this less of a

chore if you clean it up 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 and unauthorised users.

FINISHING OFF

Switch off any equipment being powered then
switch OFF the power supply. Disconnect all cables
and coil them up neatly ready for return to your local

HSS Hire Weld Depot.

GENERAL SAFETY

For advice on the safety and suitability of this
equipment contact your local HSS Hire Weld Depot.

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 cones,

barriers or tape, available for hire from your local HSS Hire
Weld Depot.

Never use this equipment if you are ill,
feeling tired, or under the influence of

alcohol or drugs.

This equipment may be used to power
equipment that 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 use this equipment in conjunction with the
health and safety recommendations of the
equipment it is being used to power.

Always switch OFF any equipment connected to
the extension cable before making any
adjustments to it.

Ensure the work area is well lit and ventilated, a

fume extractor or smoke eliminator should be used. If in
doubt, ask about lighting and ventilation equipment at
your local HSS Hire Weld Depot.

Do not work near flammable gases or liquids, petrol
or paint thinner fumes for example. Keep combustible

materials at a safe distance - at least 5m.
Check the condition of the equipment before use.

If it shows signs of damage or excessive wear, return it to
your local HSS Hire Weld Depot.

ELECTRICAL SAFETY

The HSS Extension Cables are designed to be used
with either a 415V, 5 pin 3-phase power supply or a
240V single phase power supply.

In addition, both types may be connected to a suitable
generated supply or to a main power supply.

If the equipment fails, or if its cable, socket or plug
becomes damaged, return it. Never try to repair it

yourself.
Keep cables out of harm’s way, and clear of the work

area.

Cables must always 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, always use a
suitable RCD (Residual Current-Operated Device)

available from your local HSS Hire Weld Depot. Or power
the equipment from a mains circuit with a built in RCD.

Ensure that all equipment powered by the extension
cable is switched OFF before plugging the extension
cable into the power supply.

GETTING STARTED

Take the Extension Cable to the work area, site in a
place where it will be away from pedestrian traffic.
Loosely uncoil the cable and place on the floor.

Fully uncoil additional extension cables and/or
power cables from any equipment to be powered
by the extension cable. Always ensure that cables do

not present a trip hazard.

Trailing

Socket

The HSS single phase cables have the trailing socket
fitted with a spring loaded cover which engages with a

catch on the plugs body. This is the most common type used.
To make a connection, raise the sockets cover, align

the plugs nipple with the sockets slot. Fully insert
the plug then lower the cover so that it engages
behind the plugs catch.

Whichever you are using…
All cables supplied by HSS use HO7 RN-F flexible

rubber cable and this must be taken into
consideration when performing your risk assesment.

If using an RCD adaptor, make sure that it is
positioned between the power supply and the
extension cable.

Having made sure that the power supply is switched OFF,

plug the cable into the power supply socket.

Having made sure that any equipment being supplied by
the cable is switched OFF, plug the equipment into the

cable’s trailing socket.
You can now switch the supply ON and proceed to

operate the equipment.
