Small rollers are compact in structure, small in size, large in exciting force, flexible, and convenient, but you need to pay attention to the use of rollers in winter because the low temperature will affect their performance. Below we will introduce those performances that low temperature affects walk-behind rollers:

1. The low temperature will make it difficult to start the engine of the walk-behind roller, which is caused by the high viscosity of the lubricating oil, the reduced working capacity of the battery, and the poor atomization of the fuel.

2. The viscosity of the oil of the walk-behind roller will increase with the decrease of temperature, and the flow performance will become worse, which will affect the lubricating conditions of the engine and make the rotation resistance of the crankshaft large.

3. Under low-temperature conditions, the viscosity of various oils increases, which reduces the fluidity, which brings difficulties to the operation of the walk-behind roller, and will aggravate the wear of the parts.

4. Freezing may occur during construction in cold seasons. For example, the cooling water of water-cooled engines in walk-behind rollers will freeze and crack the radiator and cylinder block.

The above phenomenon caused by low temperature tells us that when using walk-behind rollers in winter, we need to pay attention to timely replacement of lubricating oil, and regularly check the condition of road rollers, so as not to affect the use of small road rollers in construction.
