Regular Replacement: Strictly follow the maintenance intervals recommended by the equipment manufacturer (typically 1000-2000 working hours). Under harsh conditions, the interval should be shortened.
Installation Preparation:
Apply Hydraulic Oil: Before installation, apply clean hydraulic oil to the seal ring of the new filter element to prevent damage during installation and ensure sealing.
Cleaning: Before replacement, ensure the area around the filter housing is thoroughly cleaned.
Proper Installation: Hand-tighten until the seal ring contacts the base, then tighten further as per the manual (usually 3/4 turn). Do not overtighten with tools.
Inspect Old Filter: After replacement, check the old filter for excessive metal debris, which may indicate potential issues in the hydraulic system.
