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 seals (40026-338, 38151), filters (1R0716, P550388), and brake components (W18-07-903) monthly for wear, clogging, or leakage—replace immediately if damage is found to prevent system failure. Check drill bits (MD517X) for insert wear after each drilling operation, as excessive wear can reduce drilling efficiency. Inspect boiler level gauges (B49X2.5-400) regularly to ensure accurate readings.

2. Cleaning & Lubrication

Clean filter elements (1R0716, P550388) and oil coolers (7C3039) every 3 months to remove debris and prevent clogging. Lubricate moving parts (planet shafts, cardan shafts, bearings) with high-temperature lubricating oil to reduce friction and wear. Flush hydraulic hoses (Y0J0202030220801025, FB2) 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 (O-rings, SK-8H04 rubber cup) should be stored away from direct sunlight and chemicals to prevent aging. Electronic components (E-ME-AC-01F/1/A2, aviation plugs) 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 (W18-07-903) every 12-18 months (depending on usage); drill bits (MD517X) based on drilling footage; bearings every 24 months or during equipment overhauls. Pumps and valves should be inspected annually and replaced if signs of wear are present.
