￮ Sealing Elements: Apply a thin layer of food-grade silicone grease to seals before installation to prevent damage during assembly. Replace seals immediately if signs of cracking, hardening, or leakage are detected—even minor leaks can lead to major system failures.

￮ Drilling Tools: Clean the 3112mm DM753 PDC drill bit after each use to remove rock debris; inspect the diamond surface for chips or wear. Store the DP102 692 detonator adapter in a cool, dry place to prevent corrosion.

￮ Boiler Parts: Clean the WNS2-1.25-Y water level gauge monthly to remove scale buildup, ensuring accurate readings. Test the 25-QJLXK1-41 travel switch quarterly to ensure it triggers emergency shutdowns reliably.

￮ Electrical Components: Keep aviation plugs (BX3 series) clean and dry; tighten connections to 24N·m torque to prevent loose contacts. Replace plugs if the IP67 seal is damaged, as this compromises protection against dust and water.

￮ Hydraulic Components: When servicing valves and seals, use only clean hydraulic oil (ISO VG 46) to flush internal passages. Avoid disassembly in dusty environments to prevent contamination, which can cause valve sticking and seal damage.

• Storage Guidelines: Store seals, O-rings, and air bag assemblies in their original packaging in a cool, dry place (40%-60% humidity) to prevent ozone cracking and aging. Keep metal components (bearings, bolts, shear ram assemblies) coated with anti-rust oil and wrapped in VCI paper to avoid corrosion during storage. Drilling bits and detonator adapters should be stored in padded containers to prevent damage.
