With routine maintenance and proper use, hydraulic equipment will function reliably for decades. However, some common errors can cause hydraulic hoses and valves to wear out more quickly, potentially leading to premature failure and higher operating costs. Below are a few of the most common hydraulic equipment maintenance mistakes to avoid.

Common Errors to Avoid When Maintaining Hydraulic Equipment

1. Changing Oil Too Early

Unlike lubricants in combustion engines, hydraulic oil only needs to be changed when the additives have been depleted or it’s been contaminated. Changing the oil too often wastes valuable oil and introduces the risk of air or water pollution.

A variety of factors determine how quickly hydraulic fluid degrades, so consult the manufacturer’s instructions when creating a maintenance schedule. Having a professional perform an oil analysis is the best way to ensure you get the maximum usage out of your lubricant without impacting the performance of your equipment.

2. Using the Incorrect Oil

In addition to lubricating moving components, hydraulic fluid also transmits power through the system. Each piece of equipment is designed to work with fluids of a specific viscosity. Using the wrong fluid can make your equipment less efficient or cause serious breakdowns. To get the most out of your equipment, always check the manufacturer’s recommendation before choosing new oil.

3. Running the Equipment Too Hot

Lubricant loses viscosity at high temperatures, which limits its ability to transfer power or control heat. As performance decreases, wear and tear on pistons, valves, and other components increases, eventually leading to expensive breakdowns.

Most hydraulic equipment will begin to fail at temperatures over 85°C, but many systems have lower thresholds. To keep your equipment operating within safe parameters, ensure that each machine is equipped with heat measurement devices and teach your team to shut down if they’re running too hot.
