This program is applicable to the maintenance and servicing of all electric, gasoline or hydraulic-driven power trowels (including driver-operated and hand-guided types) of our company. Operator: Responsible for performing daily cleaning and inspection, and reporting any abnormal conditions. Equipment Administrator/Mechanic: Responsible for conducting regular deep maintenance, repair and record-keeping. Project Manager/Supervisor: Responsible for supervising the implementation of the maintenance plan and providing resource support. Before carrying out any maintenance, make sure that the equipment has been completely turned off, the engine/motor has stopped, the key has been removed, and all moving parts have come to a standstill and cooled down. Wear appropriate personal protective equipment (PPE), such as gloves and safety glasses. Do not clean or maintain the equipment while it is in operation. When handling fuel, engine oil and lubricating oil, keep away from fire sources and do it in a well-ventilated area. Operation process: Cleaning -> Inspection -> Report Remove large debris: Use a scraper or wooden chips to remove large pieces of concrete and mortar adhering to the power trowel plate, the bottom of the blades and the protective cover. Rinse/Wipe Timing: If the concrete has solidified, wipe it with a damp cloth. If the equipment permits and the circuit/air filter is protected, low-pressure water can be used for flushing. However, it is strictly forbidden to directly direct water at key parts such as the engine, motor, bearing housing, and control box. Key areas: power trowel plate, blades, chassis, walking wheels (or tracks). Drying and rust prevention: Use a dry cloth to wipe off water stains on the surface of the equipment. For exposed metal parts (non-friction surfaces), apply a small amount of lubricating oil for rust prevention. Power trowel and blade: Check for excessive wear, cracks or deformation. Make sure the installation bolts are tight and not loose. Transmission system Gearbox/reducer: Check for any oil leakage or abnormal noise. Belt/chain (if any) : Check the tension and wear condition, and adjust or replace them. Engine/Motor Gasoline engine: Check if the air filter is clean and visually inspect the oil dipstick (it should be in a horizontal position). Electric motor: Check if the power cord is damaged and if the plug is intact. Walking mechanism: Check the tire pressure and wear of the walking wheels, or the tightness and wear of the tracks. Fasteners: Quickly check whether the visible bolts and nuts at all parts are loose, especially at the connection points of the power trowel and the fixing points of the handle. Safety: Check whether the emergency shut-off switch and protective cover are in good condition and effective. Fill in the "Daily Inspection Form for Equipment". If any abnormality is detected (such as abnormal noise, oil leakage, severe vibration, inability to start, etc.), immediately hang the "Under Repair" sign and report to the equipment administrator. In addition to the daily content, add: Engine maintenance (gasoline engine) Change the engine oil (refer to the manufacturer's manual. The first maintenance is usually carried out after 20 to 30 hours of operation). Clean or replace the air filter element (more frequently in dusty environments). Check the spark plugs, clean the carbon deposits, adjust the clearance or replace them. Check and clean the fuel filter. Transmission system Gearbox: Check the oil level and replenish or replace the specified gear oil if necessary. Bearings: Apply high-temperature lithium-based grease to the main shaft bearings of the power trowel plate, the bearings of the walking wheels, etc. Comprehensive tightening: Use a torque wrench to re-tighten all key bolts in accordance with the torque values specified by the manufacturer. Electrical system: Check whether all wire connections are firm and clean the dust on the heat sink of the motor housing. Carried out by professional mechanics, it includes all first-level maintenance contents and adds: Deep cleaning and inspection Remove the protective cover and thoroughly clean the accumulated dust and oil stains inside. Check the wear condition of the clutch plates (if any). Deep maintenance of the transmission system Replace all the lubricating oil in the gearbox. Check for wear on the belts/chains and replace them in groups if necessary. Check the clearance and abnormal noise of the bearings, and replace them if necessary. Fuel system (gasoline engine)  Clean the carburetor. Empty and clean the fuel tank (this must be done before long-term storage). Walking mechanism Inspect the wheel axles and steering mechanism, and apply grease. For the driving type power trowel, check the hydraulic oil level and whether there is any leakage in the hydraulic pipeline. Performance test After the maintenance is completed, run the equipment no-load for 10 to 15 minutes to check for any abnormal sounds, vibrations, overheating or oil leakage, and to ensure that each control lever operates flexibly and effectively. Thorough cleaning: As mentioned earlier, thoroughly clean the equipment and dry it. Fuel treatment (gasoline engine) : Drain the fuel from the fuel tank and carburetor, or add fuel stabilizer and run the engine for 5 minutes to fill the stabilizer system. Engine maintenance Change the engine oil. Remove the spark plug, inject about 15 milliliters of engine oil into the cylinder, pull the starting rope several times to distribute the oil, and then reinstall the spark plug. Anti-corrosion treatment: Apply anti-rust oil to all exposed metal surfaces. Apply butter to the smears and leaves to prevent rust. Storage location: Store the equipment in a dry, well-ventilated and flat indoor area. Lower the power trowel plate to the ground to release the pressure of the hydraulic system (if applicable). Lift the tire off the ground or maintain the standard air pressure. After each maintenance, the maintenance date, operating hours, maintenance items, replaced parts and oils, and the signature of the maintenance person must be recorded in detail on the "power trowel Maintenance and Repair Record Card". The record card should be randomly saved for easy tracking of the equipment's history.   Core principles: Prevention first, cleanliness foremost, follow regulations, and keep complete records. Strict maintenance is not only about cost savings, but also an important guarantee for project quality and construction safety.   Note: The parameters provided in this document are for reference only and are not mandatory.

This reference document assumes no responsibility for any issues arising from failure to follow the manufacturer's instructions.    

Material selection: The correct choice of floor material can only be made after a detailed understanding of the requirements of the floor. We will detail the ground requirements below to avoid financial losses caused by mistakes or neglect. Design life: How long is the factory life, 2 years or 20 years? The final surface must be selected based on expected life or desired maintenance-free period. Construction: At what stage in the construction process will the ground system be deployed? Are the building's primary structures in place? Answering these questions will provide an idea of how the floor system will be constructed. There are two main construction methods: monolithic pouring or topping pouring. Overall pouring: This method uses a dry spreading process followed by surface troweling to form a monolithic concrete floor. These dry spread materials can only be used after the concrete floor has been poured and cannot be used on existing floors. Surface layer pouring: This method is used on existing floors by scraping or surfacing. This is a commonly used method to achieve the best bonding effect of the adhesive. The use of concrete-containing epoxy resin adhesives has better results and further increases the safety factor. Thickness: For the required floor coating, its thickness must be considered. Especially for existing buildings, increasing the thickness of the ground will cause threshold problems. In new construction projects, gaps should be reserved for the thickness of the coating. Structural load: The static and dynamic loads generated during building construction, renovation and maintenance must be considered. On the one hand, the ground system must be able to withstand these requirements, and on the other hand, the bearing capacity of the base layer should also be taken into consideration. Generally speaking, the minimum design value of the compressive strength of the base layer is 25Mpa. Traffic and mechanical wear and tear: Impact and wear and tear due to traffic must be considered. Wear is usually localized. The frequency, type and location of wear must be considered. Chemical spill: Make a list of all the types of chemicals that could leak in the area, noting the concentrations at which they leak, their temperatures, and their potential to mix on the ground. Consider what actions might be taken when leaks occur, whether these leaks are cleared immediately or remain for a considerable period of time, whether they become more corrosive as they evaporate, etc. Anti-skid: Is slip resistance an important consideration? The troweling process can be used to change the appearance of the floor as well as its slip resistance. However, in many situations, especially in wet sites, all workers are provided with anti-slip shoes to improve the anti-slip effect. Hygiene: Many modern industries, such as medicine, cosmetics, food, beverages, chemicals and electronics industries, have very high requirements on hygiene. These developing industries require clean indoor conditions. The floor must have no cracks or sharp corners, be completely dust-free, and easy to clean. They must also meet other industrial requirements, such as resistance to chemical corrosion, resistance to mechanical wear and other performance requirements. Anti-cracking ability: This is related to structural loads, especially dynamic loads. What impact will factory or traffic vibrations have on the ground? In some special areas of the building structure, such as the ground floor, the production area on the middle floor, etc. Temperature: Thermal shock may be the main cause of premature floor failure, so not only the temperatures generated by the product itself and the production process during mechanical operation need to be considered, but also the temperature of adjacent areas needs to be considered. Special attention should be paid to areas near sources of extreme cold or heat, such as cold storage or areas near blast furnaces. Beautiful colors: An attractive and pleasant environment can help increase productivity and improve industrial relations, although lighting can also play a role in this. Color can help quickly identify hazardous areas such as truck walkways, wet areas or chemicals. district. Easy to clean: For a floor system, if its cleaning agent is not considered in advance, especially for those companies with high hygiene requirements. In most cases, the corrosion of the floor caused by this cleaning agent is greater than the corrosion caused by the production process. Therefore, it is important to develop cleaning specifications that determine the frequency of cleaning and the cleaning agents to be used and their concentrations. Careful consideration should be given to using a floor varnish or sealant to facilitate cleaning and improve durability while maintaining the appearance of the floor. Drainage: When considering a floor drainage system, the final floor condition should also be considered. The combination of different building materials is particularly prone to cracks and leaks. Static electricity: Many companies are increasingly calling for anti-static floors. Anti-static floor protects sensitive electronic equipment from electronic interference and prevents spark discharges and explosions caused by static electricity accumulation. As the production speed continues to accelerate and the degree of automation continues to increase, the possibility of generating static electricity also increases, and anti-static requirements become even more important. Repair and maintenance: In any production plant, normal wear and tear of the floor is inevitable. This wear should be allowed for when selecting a flooring system. This is especially important when choosing a special color or finish, as future repairs may not be consistent with the original. Collision: Since collision causes damage to the ground, the degree and frequency of collision should be confirmed. Consider the drop height of the object. The final floor should be impact resistant. For areas that cannot meet this requirement, local protection measures should be considered, such as the use of steel plates.
