Be sure to depressurize the hydraulic system and turn off the equipment before you begin any maintenance. Locate the hydraulic oil filters within your system.

What can I do to clean an hydraulic filter?

You may need a wrench to remove the filter. A drain pan placed behind the filter will catch any hydraulic fluid that remains.

Check the filter for signs that it has been damaged or is contaminated excessively. It may be necessary to replace the filter if it is damaged beyond repair or too clogged to clean.

How can I tell if my hydraulic filters are clogged up?

The restriction in fluid flow caused by a clogged filter can lead to a decrease in hydraulic pressure and power. Unusual noises can be produced by a clogged filter. These sounds can include whining or rattling.

There are several ways to clean an hydraulic oil filter depending on its type and degree of contamination. Cleaning methods that are commonly used include:

Submerging:Soak the filter in the cleaning solution suggested by the manufacturer. Or, use a solvent suitable to dissolve contaminants. Gently agitate your filter to loosen any debris.

Backflushing:Use a source of low-pressure hydraulic fluid in the opposite direction to the normal flow if the filter was designed for it.

Ultrasonic Cleaning: In certain cases, ultrasonic cleaners can be used to remove contaminants from the filter media. These machines create high-frequency vibratory waves using sound waves. This helps to remove contaminants from filter media.

Allow the filter to air dry completely before reinstalling it. Let the filter air dry before reinstalling. Make sure the filter is seated correctly and fastened securely according to manufacturer's instructions.

Check the filter housing for leaks.
