Is manual lubrication always guaranteed to apply the proper amount of lubrication when needed?

Manual lubrication does not guarantee the application of the proper amount of lubrication when needed for several reasons. Firstly, manual lubrication relies heavily on the operator's judgment and technique, which can vary significantly from person to person. If an operator is inexperienced or not attentive, they may either under-lubricate or over-lubricate, leading to lubricant-related issues.

Moreover, in complex machinery systems, there can be varying requirements for different components. Operators may struggle to accurately assess how much lubrication a particular part requires, especially if they are working under time constraints or in challenging conditions. Additionally, factors such as the type of lubricant, environmental conditions, and the operational demands of the machinery can complicate the application process further.

While proper training may improve an operator's ability to apply the correct amount of lubrication, even trained personnel can face challenges due to human error and subjective judgment. As a result, while manual lubrication has its merits, it is not a foolproof method for ensuring the proper amount is applied consistently across all scenarios.
