What should be done to prevent hydraulic leaks during maintenance?

To prevent hydraulic leaks during maintenance, it is essential to check all seals and connections. This action involves visually inspecting hoses, fittings, and seals for any signs of wear, damage, or degradation that could lead to leaks. Regular checks can identify potential issues before they become serious problems, allowing for repairs or replacements to be made proactively.

Ensuring that all connections are tight and secure is equally important, as loose connections can also result in hydraulic fluid leaking under pressure. This careful attention to detail significantly reduces the risk of hydraulic failures and enhances overall system reliability.

Addressing the other choices highlights why they are not suitable preventative measures. Ignoring pressure gauges could lead to operating the hydraulic system outside of safe parameters, increasing the likelihood of leaks and failures. Working during off-hours does not inherently contribute to preventing leaks; maintenance should focus on thorough inspection and not just timing. Turning off electrical components may be necessary for certain procedures but does not directly prevent hydraulic leaks, which are primarily mechanical issues.
