• Machine tools generally operate from 3 phase power
supplies, are fixed in position and require skilled
labour to operate them.
• In many cases, this machinery is large.
• Specialist training is required before you can use
them.
• These machines are fitted with emergency stop
buttons.
• Machines should be kept clean, maintained as per
the manufacturers instructions, only operated by
trained personnel and safety guards should
ALWAYS be used.

HAND-HELD POWER TOOLS
• For safety reasons, hand-held tools should
ideally be powered by rechargeable batteries.
• Rechargeable batteries provide low voltages,
minimising the risk of electric shock.
• Where the design of hand-held tools prevent
them from being powered by rechargeable
batteries, 110 volt tools should be chosen over
240 volt tools.
• 110 Volt cables and transformers are yellow in
colour.

HAND-HELD POWER TOOLS
Palm sanders are
used to sand small
items of work. Palm
sanders are
lightweight, (generally
not weighing more
than 1Kg) and
operate at roughly
14000 orbits per
minute. They can be
fitted with dust bags,
and sanding paper is
held in place using
clamps. www.ngfl-cymru.org.uk

HAND-HELD POWER TOOLS
• Belt sanders are used for sanding in straight lines as well as
sanding open areas. They can be fitted with dust collection
systems to help keep work environments clean. Belt speeds are
around 350 metres per minute and a belt sander weighs
approximately 8 Kg.
