Safety Procedures
Detailed in this chapter is a list of good Health and Safety practices that Mirage Machines Ltd. advise
users to adhere to. Due to the nature of portable machine tools, not every eventuality can be
catered for and the following is not exhaustive, as such Mirage Machines Ltd. strongly advise that
the user carries out their own risk assessments based on the machining and environment in which
they intend to use the machinery.
3.3.1. Pre-Operational Safety Checks
1. Always read safety signs / labels
2. Ensure no slip / trip hazards are present in workspaces and walkways
3. Locate and ensure you are familiar with the operation of the ON / OFF starter and E-Stop (if
fitted)
4. Do not leave equipment on top of the machine
5. Ensure each tool is in good condition and securely mounted
6. Secure / Remove loose items
7. Faulty equipment must not be used. Immediately report any suspect machinery

Operational Safety Checks
1. Operator is fully conversant and trained in use of equipment
2. Keep clear of moving machine parts
3. Never leave the machine running unattended
4. Follow correct clamping procedures - keep overhangs as small as possible and check work
piece is secure
5. Set the correct speed to suit the tool, the depth of cut and the material
6. Before making adjustments and measurements or before cleaning swarf accumulations
switch off and bring the machine to a complete standstill
3.4.1. Housekeeping
1. Switch off the machine
2. Remove milling cutters, drill attachments and tap attachments and store them safely (if
applicable)
3. Leave the machine and work area in a safe, clean and tidy state
3.4.2. Potential Hazards
1. Sharp cutters
2. Moving components –hair / clothing entanglement
3. Eye injury
4. Skin irritation
5. Metal splinters and burrs
6. Flying debris
4. Handling
Customers, users and operators of the machines must be aware of the nature of the equipment
supplied.
Although inherently robust, the machine is a precision tool and may be damaged by poor handling,
tipping and falling, inadequate transport arrangements over e.g. rough terrain, misuse by operators
and use outside its design specification.
Such poor handling may result in either broken or damaged parts or disturbance to fine settings
resulting in an inability to meet the specified machining tolerances and capabilities.
