These elements ensure smooth installation and startup, preventing costly errors. Including photos of assembly stages and mounting points can be beneficial.
Creating Machine Operating Manuals: Operation and Use
After installation, the manual should guide the user through the initial startup and regular operation. This includes:
- Connection Verification – Ensuring all cables and connections are secure and the machine has access to necessary utilities.
- Technical Condition Check – Inspecting for transport damage or looseness.
- Component Activation Sequence – Some systems require a specific startup order.
- Startup Test – Verifying all functions work correctly and the operator can control all elements.
For regular operation, the manual should cover all typical scenarios, such as selecting operating modes, using control panels, and shutdown procedures. Key areas include:
- Safe Startup – Conditions for starting the machine, including safety system unlocking if needed.
- Operating Modes – Descriptions of each mode, its purpose, and switching procedures.
- Operator Training Requirements – Indicating necessary qualifications or training for operating the machine.
Creating Machine Operating Manuals: Safety and Residual Risk
Ensuring safety is the primary goal of machine operating manuals. Despite comprehensive safety features, some risks, known as residual risks, may remain. Manuals should list potential hazards and provide clear warnings, such as:
- Burn Risks – If certain machine surfaces become hot.
- Electric Shock Risks – From improper electrical connections or handling live components.
- Contact with Moving Parts – Even well-guarded parts can pose risks during maintenance.
Users must receive clear information on avoiding risks and the consequences of neglect. Using pictograms and graphic highlights like “WARNING” or “DANGER” is highly effective. Consistent warning sign patterns enhance recognition and comprehension.
Protective Measures and Personal Protective Equipment
To reduce accident risks, manufacturers often recommend specific personal protective equipment (PPE), such as safety glasses, gloves, ear protectors, suits, or non-slip footwear. If the machine generates high noise levels, hearing protection is essential. For chemical handling, masks and acid-resistant clothing may be necessary.
The manual should specify when and for which tasks operators must wear protective gear and how to respond to malfunctions or emergencies.
Noise and Hazardous Substance Emissions
The manual must address emissions related to machine operation, focusing on:
- Noise – If operator sound pressure levels exceed 70 dB(A), this must be noted. Levels above 80 dB(A) require acoustic power level disclosure and noise reduction methods.
- Hazardous Substances – If the machine emits dust, vapors, or chemicals, the manual should detail emission conditions and reduction methods, such as exhaust systems or filters.
This information is crucial for machines operating indoors or affecting the operator’s work environment, as high noise or dust levels can impact health over time.
Handling Malfunctions and Accidents
Even the best-designed machines can fail. Manuals should provide clear guidelines for unforeseen situations, including:
- Emergency Stop – Location and use of the emergency stop button.
- Machine Unblocking – Safe removal of jams or blockages, including power-off procedures before internal work.
- First Aid – Basic instructions for responding to accidents involving the operator or others nearby.
Clear, accessible information allows quick responses to limit negative outcomes. Some devices also recommend familiarizing operators with Lockout/Tagout procedures to prevent accidental machine activation during maintenance.
Creating Machine Operating Manuals: Maintenance, Repairs, and Spare Parts
Regular maintenance is essential for heavily used machines. Manuals should include:
- Recommended Service Intervals – E.g., lubricating parts every 100 hours, filter replacement every six months, key component inspections every 500 hours.
- Safe Maintenance Methods – When to disconnect power, secure the machine against accidental startup, and mark the service area.
- Spare Parts List – Especially for critical safety components, with catalog numbers or specific parameters to avoid incorrect replacements.
Clear maintenance instructions extend machine lifespan and prevent major failures and accidents from component wear or improper replacement. Manuals may also include a maintenance schedule, aiding in machinery management.
Full Lifecycle and Machine Disassembly
Machine regulations and best engineering practices require manuals to cover the entire lifecycle, including decommissioning and disposal. This information is valuable for companies planning facility upgrades or production line closures. The manual should include:
- Safe Shutdown and Disconnection – Power disconnection sequence, hydraulic or pneumatic system draining, and removal of consumables.
