Back-packed brush cutter grass cutter brush cutter

Lawn mowers, also known as brush cutters, brush cutters, lawn trimmers, etc., are mechanical tools used for trimming lawns, vegetation, etc. There are mainly two types of brush cutters: side mounted and backpack mounted, and safety issues are very important during use. Today, the editor will mainly explain the safety operating procedures of backpack mounted brush cutters.

1、 Equipment Introduction

1. A brush cutter is a mechanical device used to remove weeds in the field.

2. The backpack brush cutter consists of a gasoline engine, a handle transmission rod, and brush cutter blades.

3. The schematic diagram of the Korep backpack brush cutter is as follows:

2、 Production operation procedures

1. Preparation for startup

(1) Wear protective equipment such as rubber shoes, goggles, tight fitting clothing with long sleeves and pants.

(2) Check if the blades, clutch, and screws are loose.

(3) Check the oil level in the fuel tank, with gasoline and engine oil in a ratio of 25:1.

(4) Check if the brush cutter blade protective cover is secure.

(5) Add lubricating oil to the transmission shaft.

(6) Check if the terrain in the work area is flat and if there are too many protruding stones.

2. Power on

(1) Start the gasoline engine with a low throttle.

(2) Check if the engine sound is normal without any noise.

3. Running

(1) Buckle up and steadily step into the work area.

(2) Adjust the throttle size reasonably based on the height of the weeds.

(3) According to the depth of the weeds, pay attention to observing terrain obstacles and adjust the distance between the blades and the ground reasonably.

(4) Check if there are any abnormalities in the operation of the brush cutter.

4. Shutdown

(1) Leave the work area and lower the throttle to the minimum.

(2) Turn off the gasoline engine and let the gasoline engine blades come to a complete stop before lowering them.

(3) Stop the machine and check if there are any cracks on the brush cutter blades.

(4) Check if the screws and blade protective cover of the drive shaft are loose.

(5) Maintain and lubricate the fixed transmission parts.

3、 Safety operating procedures

1. Safety precautions

(1) Mower is a production equipment suitable for clearing weeds in the field. The operation should be strictly carried out in accordance with the safety operating procedures of the brush cutter.

(2) The operator of the brush cutter must have been on site for at least 2 months and be familiar with the operation process of the brush cutter.

(3) Mower operators should understand the routine maintenance of the brush cutter and strictly follow it.

2. Hazard analysis and control measures

(1) Hazard point analysis

Improper wearing of protective goggles, rubber shoes, and tight work clothes can cause personal injury.

Loose screws on the drive shaft can cause blade detachment and result in personal injury.

Breaking the brush cutter blade can cause personal injury.

Loose or detached blade protective covers can cause personal injury.

Improper inspection of the work area may cause personal injury if the brush cutter blades strike rocks.

Failure to adjust the blade distance in an irregular work area and incorrect actions can cause personal injury.

Aiming the brush cutter at people or other living organisms from the end can cause mechanical injury.

(2) Control measures

Before starting work, first check the protective equipment and wear it neatly.

Before starting work, check if the screws on the transmission shaft of the brush cutter are loose. If they are loose, fix them in a timely manner.

Before starting work, check whether the blade protective cover is securely fastened. If any issues are found, repair and fix them in a timely manner.

Before homework, check the geographical condition of the work area in a timely manner, and adjust the distance between the blade and the ground in a timely manner during the homework process to avoid hitting stones and injuring people.

When doing homework, swing the handle at a constant speed to avoid violent movements that may cause personal injury.

Do not aim your head at people or other creatures to avoid injury.

Finally, safety must be paid attention to during the use of the brush cutter. There are three aspects to safety: first, the safety of the machinery itself to prevent accidental malfunctions or damage; The second is to ensure the safety of operators to prevent them from being injured during operation; The third is to ensure the safety of the surrounding population to prevent machinery from harming others during operation. These three aspects are all important, especially the issue of human injury is more important than mechanical and other injury issues.
