Maintenance & Care Recommendations

Proper maintenance of spare parts is essential to extend their service life and ensure optimal equipment performance. Below are practical, easy-to-follow tips for daily use and maintenance:

1. Regular Inspection

Inspect filters (PSKHDX-40×20, BEZK183), seals (F751.14.24.02.00, 9702020336), and bearings (430103002405600012, 430104030796100005) monthly for wear, clogging, or leakage—replace immediately if damage is found to prevent system failure. Check brake components (PSZ-75 disc assembly, 513348-02 static friction disc) for wear after each operation, as excessive wear can reduce braking performance.

2. Cleaning & Lubrication

Clean air filters (RS3508, 6I 0273) and water filters (1346307) every 3 months to remove debris and prevent clogging. Lubricate moving parts (bearings, cam couplings, friction discs) with high-temperature lubricating oil to reduce friction and wear. Flush hydraulic lines (A22II, 140507011302000000) annually to remove contaminants and maintain fluid flow.

3. Storage Guidelines

Store spare parts in a dry, clean, and temperature-controlled environment (10-25℃) to avoid rust and damage. Seals and rubber components should be stored away from direct sunlight and chemicals to prevent aging. Electronic components (6SY7010-0AB64, SK-OM4000) should be stored in anti-static packaging to protect sensitive circuits. Explosion-proof components should be stored in a dust-free environment to maintain their safety certification.

4. Replacement Schedule

Follow these recommended replacement intervals: Filters and filter elements every 6 months or 500 operating hours; seals and gaskets every 6-12 months (or sooner if leakage is observed); brake components (PSZ-75 disc assembly, 513348-02) every 12-18 months (depending on usage); bearings every 24 months or during equipment overhauls. Pumps and valves should be inspected annually and replaced if signs of wear are present.
