Winter Maintenance Checklist – What Actually Matters If you've ever walked out to a jobsite on a 20°F morning and heard your excavator crank slow, you know the feeling. Cold weather exposes every weak point in a machine – old batteries, thin coolant, gelled fuel, stiff hydraulics. Most of these problems are preventable. Here's what to check before the temperature drops. 1. Battery – Cold Starts Kill Weak Batteries A battery that starts fine in summer can fail completely in winter. Cold weather reduces battery capacity by up to 35%. Clean the terminals, check the voltage (should be 12.6V or higher), and load-test it if it's more than two years old. Replace it before it leaves you stranded. 2. Coolant – Check the Freeze Point Straight water freezes and cracks engine blocks. Use a coolant tester and make sure your mixture protects down to at least -25°C (-13°F). A 50/50 mix of antifreeze and distilled water is the standard for most machines. If you're not sure, drain and refill with fresh coolant. 3. Fuel System – Keep Diesel Flowing Diesel fuel gels in cold weather. The wax in the fuel crystallizes and clogs filters. Use winter-grade diesel or add an anti-gel additive before the first freeze. Change the fuel filter and drain the water separator – water in the fuel line freezes and stops the engine dead. 4. Hydraulic Fluid – Warm It Up Slowly Cold hydraulic fluid is thick. It doesn't flow well, and it puts extra strain on pumps and valves. Let the machine warm up at idle for 10-15 minutes before working it hard. Don't rev the engine to warm it up faster – that just cavitates the pump and causes wear. 5. Belts and Hoses – Cold Makes Rubber Brittle Rubber belts and hoses get stiff and crack in cold weather. Check the fan belt, alternator belt, and all hydraulic hoses for cracks, fraying, or bulges. Replace anything that looks suspect. A snapped belt on a cold morning means a long wait for a tow. 6. Air Intake and Heater – Keep It Breathing Check the air filter and intake system. Cold air is denser, so the engine needs clean air to run efficiently. Also test the cab heater – if it's not working, you're in for a long, cold shift. Flush the heater core if the heat is weak. 7. Undercarriage – Ice and Mud Are a Bad Mix Mud and debris freeze on the undercarriage overnight. That ice buildup can damage track tensioners, rollers, and sprockets. Clean the tracks and undercarriage at the end of each day – especially if you've been working in wet or muddy conditions. What About Fire Prevention? (A Quick Note) Fires do happen more often in winter – not because of the cold, but because of the heaters. Operators run cab heaters, defrosters, and sometimes portable heaters. Those extra electrical loads stress wiring that's already old and brittle. Check the wiring harness for chafing or exposed wires. Keep a dry powder extinguisher mounted in the cab – and make sure it's not expired. A small fire extinguisher is cheap. A burned machine isn't. Daily Winter Routine – 5 Minutes That Save You Hours Walk-around inspection: Look for leaks, loose bolts, and damaged hoses before you start. Warm-up idle: Let the machine idle for 10-15 minutes before working it hard. Check fluids: Oil, coolant, and hydraulic fluid levels – every morning. Clean the undercarriage: Mud and ice buildup causes track damage. Test the heater: Make sure the cab heater and defroster are working.

Mini excavators are also known as the smallest excavators in China. The minimum mini excavator is 15 machines (1.5 tons); the definition of mini excavators varies from country to country, such as: The United States, the Netherlands and Spain), 1 to 3 dwt is called a small excavator and its commodity is popular. The main points and common problems of small excavator leveling work. It is not too difficult to use small excavators to level the road. It is not easy to say that it is simple. Why is it said that, the first small excavator to use Delide small excavation opportunities is much simpler, and at the same time it is efficient, and then there is the use of small excavators to level the road to grasp the following aspects and work experience. Posture points: 1. When preparing a leveled ground in advance, first estimate the degree of the two sides of the road, then select the correct elevation point from the high end of the road, level the ground to the low-lying end one after another, and finally dig out the soil above the elevation point. , Fill and level areas in low-lying land, estimate leveling. 2. Lower the arm of the small excavator, open the second arm to the angle of about 45 degrees with the arm up and down; open the bucket, so that the digging bucket mouth and the second arm are basically level; the bucket falls into the road, retract the second arm, and raise the arm , Pull the soil backward; the equipment rotates one bucket after another in order to level the ground. 3. Final estimation and leveling, according to the actual landform conditions, the arms, two arms and the digging bucket are controlled harmoniously, and the leveling work is in progress. The main points and common problems of small and small excavator leveling work, matters that must be paid attention to: 1. The car must stand level. If the excavator can’t stand level, the fairy will be uneven. 2. Keep your eyes alive. For a long time, follow the laminated glass to keep a close eye on the actual operation of the bucket. It is very prone to illusions and fatigue. Therefore, your eyes should always look at the smoothed road from each angle. You can find that the angle of view is different. Your feelings are also different. 3. Select the surrounding reference, such as the area that has been leveled, the color of the soil layer, etc. 4. There are also cases where the bucket maintains a fixed angle of view and uses the bucket and basic slope protection to accurately measure the aspect ratio. There are also cases where the excavator stands flat, close to the already level road surface, and rotates 180 degrees. Five, firmly believe in the equipment, do not have to believe in your own eyes too much. , After working for a long time, the eyesight is fatigued, and some errors will of course occur. At this time, you must fully believe in the accuracy of the equipment. Sixth, often go backwards, look at the smooth road from another angle. , After digging a piece, I feel the same, go backwards about the length of a parking space, and then look at the floor plan dug in front, you can easily see how much, it is my own specific exploration, especially suitable Working conditions with a darker soil tone. ,

What should I do if the engine stalls and slows down in the mini excavator? 1. Exhaust pipe Under normal circumstances, exhaust blockage is one of the basic reasons for reducing fuel consumption. When the exhaust pipe is blocked, the exhaust power will directly decrease. Therefore, it is necessary to check the carbon deposits in the exhaust pipe on time in daily work. If the back pressure exceeds 3.3 Kpa, it is necessary to clean it. 2. Air filter If the air filter is dusty or dusty, the power of the filter will decrease linearly, which then prevents air circulation and affects the output of the engine. Therefore, the alias must be timely. In severe cases, it can be replaced with a new air filter, air filter or filter paper. 3. Pistons and cylinder liners With the increase of the mechanical service time, the strain loss between the piston and the bushing gradually increases. Excessive wear on the piston ring will have severe negative effects on the engine, and may cause undesirable effects, such as difficulty in incineration and incomplete incineration. Therefore, please check the cylinder liner and piston ring on time. 4. Fuel filter When air enters the fuel filter, the pipe is directly blocked, and the oil passage smoothly reaches that position. This directly leads to a lack of electricity. In severe circumstances, it may affect the fire. Therefore, the fuel system must be filtered in time. If necessary, you can select and replace a new diesel filter again (filter information: glass fiber filter paper, chemical fiber filter paper, etc.). 5. Cooling smooth system The basic reason for the overheating of the engine oil is the faults of the mechanical cooling system or the smoothing system (circulating smoothing system, gathering smoothing system, etc.). Therefore, when the exhaust temperature of the diesel engine increases, the cooler and radiator can be viewed. Clean the dirt. The company's advanced control equipment can provide high-distribution valve hydraulic systems for high temperature, slow motion, no power, shutdown, difficulty in starting, boom problems and hot water temperature treatment solutions. This is how you know about the engine stalling and slowing down of the mini excavator. Do you understand it?

The use of hydraulic oil for small rollers is a very important part of the whole machine, but there are still many friends who don’t know much about the use of hydraulic oil. It is important to know that incorrect use will cause damage to the equipment and affect its functions. For newcomers to small rollers There are still a lot of things to pay attention to, so do you know what we should pay attention to? Next, we will give you a detailed introduction to the precautions for the use of hydraulic oil for rollers. Small road rollers belong to the category of road equipment in construction machinery. They are widely used in filling compaction operations of high-grade highways, railways, airport runways, dams, stadiums and other large-scale engineering projects. They can compact sandy, semi-cohesive and cohesive soils. , Roadbed stabilized soil and asphalt concrete pavement layer. The compact roller is suitable for various compaction operations by the gravity of the machine itself, so that the compacted layer will be permanently deformed and compact. 1. First of all, hydraulic oil should be selected according to the brand recommended by the manufacturer and the working environment and temperature factors of the machine. For some machines with special requirements, special hydraulic oil should be used. In the winter in the north, it is better to choose low-condensation hydraulic oil. When the maintenance of hydraulic components and systems is inconvenient, anti-wear hydraulic oil should be used. 2. Regularly check the oil quality and oil level. Keep the hydraulic oil of small rollers clean to prevent impurities such as metal chips and fibers from entering the oil. The oil tank should be thoroughly cleaned before adding oil, and the new oil should be filtered (the accuracy of the filter is generally 5-10μm), otherwise the performance of the hydraulic system and the life of the hydraulic pump will be greatly affected. 3. Excessive hydraulic oil temperature will seriously affect the normal use of the machine, reduce the service life of the hydraulic components of the small roller, and increase the maintenance cost of construction machinery. It is recommended that the roller use hydraulic oil in winter. Choose anti-wear and high-temperature hydraulic oil in winter and regularly check the use of the roller and replace the hydraulic oil in time. The temperature rise of the oil in the oil tank of a small roller does not exceed the allowable range of the hydraulic oil, and all work generally requires not to exceed 60°C, otherwise the cooling system of the hydraulic oil needs to be checked. When the oil temperature is too low, the oil should be preheated so that the oil temperature gradually rises before starting the operation.

The simple way is to clean, you can prepare a small air compressor. The fuel is released during the cleaning process, but be careful not to let it separate and leave some fuel. The compressed air then reaches the bottom of the fuel tank through the pipe Plastic, SO that Continuously The Diesel Engine Rolls Cleaning and stops. During the this Process , The position and direction of Changes The Gas Pipeline from Time to Time, thereby Fuel Tank Cleaning The Entire. the After Cleaning, The Fuel Tank IS Immediately emptied, allowing impurities suspended in the oil to flow out together with the diesel. ogether with the diesel. Assuming that the discharged diesel is dirty, it needs to be cleaned again by the above method until the released oil is free of impurities. The steam method works well, but it is only suitable for qualified applications. Assuming you have the conditions to use steam, you can try. When cleaning, it takes about an hour for the small excavator to discharge the diesel oil, take out the fuel tank, and then pour a large amount of water into the tank, pour the fuel into the water from the filling port, and make the water in the water tank boil. At this time, the glue and various impurities on the inner wall of the water tank are dissolved or peeled off from the wall. Rinse the water tank thoroughly twice in a row. Another commonly used method is the solvent method. The chemicals used are corrosive or corrosive. First clean the water tank with hot water, then use compressed air monotonously, then soak the 10% aqueous solution in the water tank, and finally rinse the inside of the water tank of the small excavator with clean water.

No matter what you do, you will form a habit after doing it for a long time. The excavator is no exception. We must continue to maintain good habits, and we must discover and overcome those bad habits early. Below, let's take stock of the common bad habits of excavator driving. 01 After the construction is over, park the excavator casually This is not only a bad habit, but also a big safety hazard! The most important thing about excavators is safety. Some operators, regardless of whether the road is flat or uneven, just stop the excavator randomly. It is easy to stop, but it is troublesome to start. How to check the oil if it stops unevenly? How to release the water? Especially if the excavator is parked in a dangerous place, isn't this digging a hole for yourself? Correct posture: The excavator should be parked in a flat, solid place that does not obstruct traffic, put in reverse gear and implement the parking brake. When necessary, such as parking on a ramp, the front and rear of the walking mechanism are cushioned with wedges. Turn the fuselage straight, the bucket falls to the ground, the working device lever is placed in the neutral position, and the driver can leave the excavator only after the windows and doors are locked. 02 When it starts, it will start when it arrives As soon as you get in the car, you are passionate and full of energy. Do you have this habit? Correct posture: Drain the water before the excavator, otherwise, the water will get into the oil-water separator, or even into the oil pump, the oil pump will be easily destroyed. Whether it is winter or summer, the excavator must be warmed up first when it is started, but the warm-up time in summer does not need to be so long. 03 Turn on the air conditioner without closing the windows If the indoor temperature cannot be reached when the doors and windows are opened, the cold pump will not jump, and it will be destroyed after a long time. Besides, there is so much dust on the construction site, opening doors and windows allows the expansion valve to suck more dust and block it, resulting in poor air conditioning performance. Correct posture: Four words, close doors and windows 04 Always challenge thrilling moves Don't take risks with your own body. Excavators are inherently dangerous and require stimulation. In online language, it means "no zuo no die". Correct posture: The excavator should put safety awareness first. When looking for excitement is not working, you should pay attention to the word "stable" when walking in the rivers and lakes. 05 Two legs in the cab and smoke Although you think it's very awkward, don't do these things during construction. In case of an emergency, there is no time to respond. "Safety comes from caution, accidents are careless"... Such a title is familiar, isn't it? 06 Habitually Excessive operation and friction are likely to cause machine wear, turntable bearings are also easy to wear, and at the same time, the safety valve of the brake hydraulic system is easy to jam. Correct posture: When the excavator rotates, the slewing clutch and the slewing mechanism brake are used to rotate smoothly. 07 The excavator inclines too much during construction In this way, the oil pressure will not be able to supply, and once in a while, it will cause high temperature in the long-term, except for special circumstances. Correct posture: A safe and stable platform should be established before construction to enable the excavator to operate safely and efficiently. 08 The excavator turns off as soon as it stops The engine temperature of the excavator is too high when the flame is suddenly turned off, and the water in the engine cannot circulate the water tank, especially in summer. Correct posture: Run at idle speed for 5-10 minutes, and then turn off the engine after the temperature drops. I don’t know how many of the above bad habits have you hit? In any case, it is still too late to make corrections. Small ones will hurt the excavator, and large ones will hurt people. Don't make jokes about the safety of life and property.
