Complete Guide to Safe Use of Corn Threshers
The corn thresher is an important machine in modern agriculture, greatly improving the efficiency of corn harvesting and processing. However, like any machinery, it carries certain safety risks during use. Therefore, operating the corn thresher safely and correctly not only extends the machine’s lifespan but also protects the operator. The following summarizes key safety points to help farmers work efficiently and safely.

Preparation and inspection before use
Read the manual carefully
Before using the corn thresher for the first time, carefully read the manual to fully understand the machine’s structure, performance, and operating procedures.
Check safety signs and instructions
Before the operation, pay close attention to the safety signs, operating instructions, and nameplates on the machine. If any are missing or damaged, they should be replaced promptly to avoid overlooking dangerous areas during work.
Inspect mechanical components before the season
At the beginning of each harvesting season, inspect key parts such as the threshing drum and threshing teeth for cracks or deformation. If parts need replacement, follow the manual’s instructions or work under the guidance of experienced maintenance personnel.
Do not modify the machine
Users must not modify the machine arbitrarily, as this can damage the mechanical structure or create safety hazards.
Power and safety requirements
- When changing or selecting the power source, the main shaft speed must strictly follow the range specified in the manual.
- Exposed transmission parts must have protective covers installed.
- When using an electric motor, ensure it is properly grounded to prevent electric shock.

Safety measures before the operation
Test run
Before operating, perform an empty-load test run to check for abnormal friction, noise, or vibration, and ensure the drum rotates in the correct direction. Over-speed operation is strictly prohibited.
Signal before starting
Before starting the machine, ensure no one is nearby and give a clear start signal to prevent accidental injuries.
Operator requirements
Do not operate the machine under the influence of alcohol, if pregnant, or if underage.
Operators must wear proper clothing; tighten straps on clothes and hats, and women with long hair must wear a safety helmet to prevent hair from getting caught in moving parts.

Precautions during operation
Avoid dangerous operations
- Do not put hands into the feed inlet, discharge outlet, or any other moving parts.
- Do not stand behind the discharge outlet to avoid being hit by objects thrown by high-speed rotating parts.
- Do not feed stones, wood, metal, or other hard objects into the machine.
Stop immediately for blockages
- If a blockage or abnormal situation occurs during operation, stop the machine immediately. Do not clean or inspect the machine while it is running.
Fire safety
- Tractor and diesel engine exhaust pipes must be equipped with fire extinguishing devices.
- Keep motors and transmission parts free of crop residue to prevent overheating and fire hazards.

Regular maintenance and inspection
Check fasteners
Regularly inspect fasteners on the threshing drum, fan, bearing seats, and other moving parts. If any are damaged, loose, or missing, address them promptly.
Daily maintenance
Keep the equipment clean and free of debris, and regularly lubricate moving parts to ensure the machine operates efficiently and smoothly.
