During operation, strictly adhere to safety regulations for the Nianpeng 4-15 semi-automatic brick-making machine to avoid accidents caused by mechanical injuries, electrical failures, or operational errors. The following are key safety precautions and key points:
1. Safety Inspection Before Starting (Required)
Equipment Status Verification
Check all moving parts (such as the mold, press head, and conveyor belt) for foreign objects and loose mold mounting bolts to prevent collisions or mold jams caused by component misalignment after startup.
Confirm that the hydraulic system oil level is within the standard range (1/2-2/3 of the level gauge), there are no leaks in the piping, and the hydraulic valves and pressure gauges are displaying normal readings to prevent sudden equipment shutdowns due to oil shortages or abnormal pressures during operation.
Check the electrical system: Ensure cables are intact, plugs and sockets are securely connected, the emergency stop button is functioning properly (pressing it should immediately shut down the machine), and there is no dust accumulation in the control cabinet to avoid short circuit risks. Environmental and Protective Preparations
Clear debris around the equipment and ensure the operating area (especially around the molds and on both sides of the conveyor belt) is clear of obstacles. Allow at least 1.5 meters of safe passageway to prevent collisions when handling bricks.
Operators must wear protective gear: a hard hat, non-slip work shoes, and protective gloves (to avoid contact with raw materials or hot parts). Long hair should be tied up and capped. Loose clothing and jewelry are prohibited to prevent entanglement in moving parts.

II. Safety Operating Procedures During Operation
Illegal Operations Strictly Prohibited
While the equipment is operating, do not place hands, head, or other body parts into the mold, under the pressing head, or in the conveyor belt drive area. Do not use your hands to clean residual material from the mold (this requires stopping the machine and disconnecting the power supply).
Do not arbitrarily adjust equipment parameters (such as pressing pressure or vibration frequency) or short-circuit safety protection devices (such as limit switches and overload protection). Parameter adjustments must be performed by qualified personnel through the control cabinet.
Avoid overloading production: Strictly feed material according to the equipment's rated capacity. Do not feed excessive material to achieve high speed. This prevents material overflow, mold jams, or motor overload and burnout.
Handling Abnormal Situations
If the equipment detects unusual noises, vibrations, oil leaks, or brick forming defects (such as cracks or chipped corners), immediately press the emergency stop button, disconnect the main power supply, and investigate the cause. Maintenance is strictly prohibited while the equipment is operating.
In the event of a sudden power outage, turn off the main power supply. After power is restored, recheck the equipment to confirm that no components are stuck or material is accumulated before restarting the machine to avoid mechanical shock caused by sudden startup.

III. Safety Maintenance After Shutdown
Equipment Cleaning and Maintenance
After shutting down, the main power must be disconnected. Once the equipment is completely still, clean any remaining material inside the mold and debris from the conveyor belt. Use a brush or compressed air to clean the mold (do not use water directly on electrical components).
Regularly lubricate moving parts (such as guide rails and bearings) and inspect and replace hydraulic system filters. Maintenance must be performed with the power off to avoid accidentally pressing the start button.
Mold Replacement and Commissioning Safety
When replacing a mold, disconnect the power supply and display a warning sign (e.g., "Maintenance in Progress, Do Not Close the Power Supply"). When working with multiple people, clear command signals are required to prevent the mold from falling or being crushed during lifting.
After installing a new mold, perform a no-load test run to check mold positioning accuracy and motion coordination. Ensure there are no collisions or jams before resuming production with material. Operators must remain in a safe area during the test run.

IV. Other Key Considerations
Personnel Qualification Requirements: Operators must undergo qualified training before taking up their duties and be familiar with the equipment's operating procedures and emergency shutdown procedures. Unauthorized operation by unlicensed personnel or personnel not designated for the position is strictly prohibited.
Electrical Safety Management: Equipment must be reliably grounded (ground resistance ≤ 4Ω). During thunderstorms, equipment must be shut down and the main power supply disconnected to prevent lightning damage to electrical components or electric shock.
Raw Material Safety Protection: If raw materials contain dust (such as fly ash, sand, and gravel), wear a dust mask. Regular health checks should be performed during long-term operation to prevent the hazards of dust inhalation.
Equipment Periodic Maintenance: Regularly inspect vulnerable components such as hydraulic system seals, electrical contacts, and drive belts according to the manual. Replace aging parts promptly to prevent safety accidents caused by component failure.

Summary
The key to safe operation of the Nianpeng 4-15 semi-automatic brick-making machine is "prevention first, standardized operation, and timely loss prevention." Operators must strictly adhere to the entire process, including pre-startup inspection, in-operation monitoring, and post-downtime maintenance. Avoiding haphazard thinking and illegal operations will minimize the risks of mechanical damage and electrical failure, ensuring personal and equipment safety.
