What are the precautions when using a backpack small harvester

The backpack small harvester is characterized by its lightness, flexibility and simple operation. It is suitable for harvesting crops in small plots or complex terrains such as mountains and hills. When in use, extra attention should be paid to aspects such as pre-operation preparation, operation norms, safety protection, equipment maintenance, and response to special environments. The specific details are as follows:

I. Preparations Before Operation

Check the status of the equipment

Visual inspection: Confirm that the machine body has no cracks or deformations, and that the fasteners (such as bolts and nuts) are not loose to prevent them from falling off or breaking during operation.

Power system

For fuel-powered models: Check if the fuel tank is full, whether the fuel lines are aged or leaking, and ensure smooth engine start-up.

For electric models: Check if the battery power is sufficient and if the charging interface is intact to avoid power outages during operation.

Cutting components: Check if the blade is sharp and has no notches, and if it is installed firmly to prevent it from breaking or flying out and injuring people during cutting.

Transmission system: Check the tightness of the belt or chain. If it is too loose, it is prone to slipping; if it is too tight, it will accelerate wear. It needs to be adjusted to an appropriate state.

Wear protective equipment

Head protection: Wear a safety helmet to prevent your head from being hit by flying debris or blade fragments.

Body protection: Wear long-sleeved work clothes and wear-resistant long pants to avoid direct skin contact with sharp parts or crop stems.

Hand protection: Wear cut-resistant gloves to prevent your hands from being cut by blades or scalded by high-temperature components.

Foot protection: Wear anti-slip work shoes to avoid slipping or being pricked by sharp objects.

Hearing protection: When using fuel-powered models for a long time, wear earplugs or earmuffs to reduce noise damage to your hearing.

Clear the operation site

Remove hard objects such as stones, branches and iron wires from the site to prevent the blades from breaking or splashing and injuring people upon collision.

Check if the terrain is flat. Avoid working on steep slopes, deep ditches or soft mud to prevent the equipment from overturning.

Ii. Operating Norms

Startup and shutdown

Before starting: Ensure that the equipment is in neutral gear. For fuel-powered models, close the air damper; for electric models, make sure the power switch is turned off.

When starting: Operate in accordance with the manual. For fuel-powered models, pull the start rope evenly. For electric models, hold down the start button for 3 to 5 seconds.

When shutting down: First, turn off the power (for fuel-powered models, adjust to idle speed for 1-2 minutes before turning off the engine). Wait until the blade stops rotating before lowering the equipment.

Working posture and speed

Posture: Maintain body balance. When carrying the equipment, adjust the shoulder straps and waist belt to a comfortable position to avoid muscle strain caused by prolonged unilateral force.

Speed: Adjust the forward speed according to the crop density and height to avoid cutting too fast, which may cause missed cuts or blade jamming.

Direction: Maintain linear operation and minimize frequent turns to reduce equipment wear and operational difficulty.

Adjustment of cutting height

Adjust the gap between the blade and the ground according to the height of the crop. Generally, keep the distance between the blade and the ground at 5 to 10 centimeters to prevent the blade from touching the ground and causing wear or chipping.

When cutting tall crops such as corn, the position of the blade can be appropriately raised to prevent the stems from entangling the blade.

Iii. Safety Protection

Prevent blade injury

When working, ensure that there are no people or animals within 1 meter in front of the blade to avoid injury from flying debris.

When changing the blade or cleaning the cutting cavity, be sure to turn off the power first and unplug the power plug (for electric type) or close the fuel valve (for fuel type) to prevent accidental start-up.

Avoid burns from high temperatures

When the engine of a fuel-powered model is running, the temperature is relatively high. Do not touch the exhaust pipe, cylinder block or other parts to prevent burns.

After long-term operation, the equipment should be cooled down before cleaning or maintenance.

Prevent electric shock and fire

Electric equipment should use power cords and sockets that meet standards to prevent fires caused by aging or overloading of the lines.

Fuel-powered models should be kept away from open flames and flammable materials. When refueling, turn off the engine and wait for 5 minutes until the oil temperature drops before operating.

Iv. Equipment Maintenance

Daily cleaning

After each operation, wipe the dust and oil stains on the surface of the equipment with a dry cloth, and clean the residue and weeds in the cutting cavity to prevent corrosion or blockage.

For fuel-powered models, the air filter needs to be cleaned to prevent dust from entering the engine and affecting performance.

Regular maintenance

Lubrication maintenance: After every 10 hours of operation, apply grease to the transmission components (such as bearings and chains) to reduce wear.

Blade inspection: After every 50 hours of operation, check the wear condition of the blade. If the cutting edge becomes dull or has notches, it needs to be replaced or ground in time.

Belt/chain adjustment: After every 20 hours of operation, check the tightness of the belt or chain and make adjustments or replacements if necessary.

Long-term storage

After cleaning the equipment, store it in a dry and well-ventilated room, avoiding direct sunlight and rain.

For fuel-powered models, the fuel in the fuel tank needs to be drained to prevent the fuel quality from deteriorating and blocking the fuel passage. The electric type needs to be fully charged with the battery and charged regularly (once every three months) to prevent the battery from being discharged and damaged.

V. Response to Special Environments

Damp environment

Avoid working on rainy days or when the dew has not yet dried to prevent water from entering the equipment, which may cause short circuits or rust.

If it must be used in a damp environment, a waterproof cover should be added to the electric equipment, the operation time should be shortened, and the equipment should be dried in time.

High-temperature environment

When working in summer, avoid continuous use for a long time. Stop the machine and rest for 10 minutes every hour to prevent the engine from overheating.

Regularly inspect the cooling system (such as the heat sinks of fuel-powered models) to ensure good ventilation.

Complex terrain

When working in mountainous or hilly areas, it is necessary to maintain a low speed, avoid sharp turns or starting on steep slopes, and prevent the equipment from overturning.

When encountering obstacles, slow down in advance and detour. It is strictly forbidden to force through to avoid damaging the blade.
