WOOD OCCUPATION SKILLS
JOINERY WORKSHOP:MACHINE TOOLS AND
PORTABLE POWER TOOLS

• 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 TOOLSPalm 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.

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.

HAND-HELD POWER TOOLS
• Nail guns are designed for high speed nailing, and can be pneumatically driven. They should only be operated with the muzzle touching the work to be nailed.
