There are many types of wood splitters on the market, and there are several kinds of hydraulic fluid that can be used to operate the splitter. Identifying the correct hydraulic fluid for a wood splitter is easier when the person cutting or splitting the wood knows in what environment, whether hot or cold weather, the wood splitter will be used. The workload of the wood splitter is also a consideration.
Most hydraulic fluid is made from petroleum-based products such as crude oil or mineral oils. This type of hydraulic fluid can come in multigrade or monograde. The environment in which the wood splitter is being operated affects which grade is used. A person using a wood splitter in both hot and cold temperatures must use a multigrade hydraulic fluid. Using a wood splitter in a more constant temperature environment, whether the environment is cold or hot, can use a monograde hydraulic fluid.
Water-based hydraulic fluid can have additives such as non-detergent or detergent, depending on which water-based fluid is used. A non-detergent additive prevents the build-up of foam inside the gear case of the wood splitter and is more fire-resistant than the detergent additive. Detergent additives do a better job of lessening wear on the gears. Water-based hydraulic fluid is commonly used in warmer temperatures to avoid problems with freezing.
Synthetic-based hydraulic fluid utilises a variety of chemicals and anti-wear additives to help wood splitters with a high workload. The synthetic fluids can be multigrade, monograde, detergent or non-detergent depending on the environment and temperatures during use. Synthetic hydraulic fluid can help extend the life of a wood splitter used in different types of environments and under changing working conditions.
