Gas Strut Maintenance and Safety
Gas struts are precision-engineered components under high pressure, and their care directly affects safety and reliability.
Cleaning and Handling
- Wipe regularly: Clean the piston rod with a dry, lint-free cloth to prevent dust buildup.
- Store and mount correctly: Always position gas struts with the piston rod pointing downward. This keeps seals lubricated and prevents premature wear.
- Operate gently: Avoid slamming or forcing the window, which stresses the struts.
What to Avoid
- Do not grip or scratch the piston rod: Damage compromises seals and leads to leaks.
- Avoid external lubricants or solvents: These break down seals and attract dirt.
- Do not paint struts: Paint can stick to the rod and damage seals during operation.
- Protect from heat and punctures: As sealed pressure vessels, struts can rupture if pierced or overheated.
Inspection and Replacement
- Check for leaks or rust: Oil stains, dents, or corrosion signal a failing strut.
- Test window performance: If it no longer holds open or moves unevenly, pressure may be lost.
- Replace promptly: Swap out damaged struts immediately—preferably in pairs for balance.
Safety Precautions
- Wear protective gear: Gloves and safety glasses reduce risk when handling struts.
- Use proper tools: Some models require special clips or mounting aids.
- Seek professional installation for large projects: Heavy or multiple strut installations should be handled by trained technicians.
