1. Preparation and safety precautions before operation
Inspect the machine:
Before starting the ride-on trowel, carefully check all parts of the machine. Check whether the trowel blade is firmly installed and not loose, deformed or damaged. Because if the trowel blade falls off during operation, it may fly out at high speed and cause serious harm to the operator and surrounding personnel. At the same time, check the transmission parts, such as belts, chains or drive shafts, to ensure that they are properly connected and not excessively worn or loose, so as to avoid malfunctions during operation.
Also check the control system of the machine, including the start button, speed adjustment knob, steering device, etc., to ensure that these parts can work properly. For example, the start button should be sensitive, the speed adjustment knob can accurately control the speed of the trowel, and the steering device should be flexible and effective to avoid accidents caused by control failure during operation.
Familiarize yourself with the operating environment:
The operator needs to be familiar with the conditions of the construction site in advance. Understand the size, shape, boundaries and ground conditions of the site, such as whether there are potholes, bumps, obstacles or water accumulation. For sloped ground, special attention should be paid to the size and direction of the slope, because the ride-on trowel may be out of control on a steeper ground. At the same time, ensure that there are no unrelated personnel or other equipment around the construction site, and set up obvious warning signs to prevent others from entering the construction area by mistake.
Personal protective equipment preparation:
Operators must wear personal protective equipment. Including safety helmets to protect the head from possible collision injuries; protective gloves to prevent hands from being pinched by the rotating parts of the machine or scratched by sharp ground materials; protective shoes with anti-slip and anti-smashing functions to avoid slipping or heavy objects hitting the feet during operation. In addition, depending on the construction environment, earplugs (because the trowel is noisy when working) and goggles (to prevent dust and debris from entering the eyes) may also be required.
2. Safety points during operation
Correct driving posture and operation method:
When the operator is sitting in the driver's seat, he must maintain the correct driving posture, sit upright, hold the steering wheel or operating handle with both hands, and place his feet on the pedals (if there are pedals). When driving the trowel forward, backward or turning, operate smoothly and avoid sudden acceleration, sudden braking or sharp turns. For example, a sudden sharp turn when the trowel is running at high speed may cause the machine to roll over and cause a serious accident.
Operate strictly in accordance with the operating instructions and do not arbitrarily adjust the machine's parameters or make unauthorized modifications. For example, do not operate beyond the speed range specified by the machine, because too high a speed will increase the risk of the machine losing control and is not conducive to obtaining a good troweling effect.
Pay attention to the operating status of the machine:
During operation, always pay attention to the operating status of the trowel. Observe the power system of the machine, such as the engine or motor, for abnormal noise, vibration or heating. If the machine is found to be underpowered, making abnormal sounds or vibrating violently, stop operating immediately, check the cause and troubleshoot before continuing to use it. At the same time, pay attention to the working condition of the trowel blade to see if the trowel blade is deflected, shaking or unevenly in contact with the ground. These problems may affect the trowel effect and cause damage to the machine.
Keep a safe distance from the surrounding environment and personnel:
When driving a trowel, keep a safe distance from surrounding buildings, walls, scaffolding and other fixed obstacles. It is generally recommended to keep a distance of at least 1-2 meters to prevent the machine from colliding with obstacles and being damaged or causing injuries to the operator. At the same time, keep a safe distance from other construction workers to prevent the rotating parts or moving body of the machine from hitting others. If other people need to enter the construction area, the operation of the machine should be stopped first and then continue after the people leave.
3. Safety precautions after operation
Parking and maintenance of the machine:
When the trowel work is completed, park the machine in a safe place. Choose a flat, dry, and obstacle-free place to park, avoid parking the machine on a slope or unstable ground to prevent the machine from sliding or tipping over. If the machine needs to be parked for a long time, it is best to raise the trowel blade (if the machine has this function) to keep the trowel blade off the ground to reduce the corrosion of the trowel blade by ground moisture and prevent the trowel blade from contacting the ground and being damaged when accidentally started.
After the machine is parked, it should be maintained according to the prescribed maintenance procedures. Clean the dust, concrete debris and other debris on the surface of the machine, and check whether the various parts of the machine are damaged or need to be replaced, such as the degree of wear of the trowel and the tightness of the transmission parts. Regular maintenance of the machine can extend the service life of the machine and ensure the safety and performance of the next use.
Safety inspection and record:
After each operation, the safety status of the machine should be checked and recorded. The record content includes whether the machine has a fault, whether maintenance has been performed, and the operation status of the operator. These records can help track the use and safety status of the machine, provide reference for subsequent operation and maintenance, and help to discover potential safety hazards in a timely manner.
