4. FAQ

Q: What preparation is needed before installation?
A: Thoroughly clean the cylinder bore and piston rod, clear away dirt and old seal residues, and check for surface scratches.

Q: Do we need to apply extra sealant?
A: No. Additional sealant may clog oil lines and cause hydraulic system malfunctions.

Q: What to do if a seal gets damaged during fitting?
A: Replace it with a new one right away. Even minor damage will cause continuous oil leakage.

Q: How to judge if seals need replacement in daily check?
A: Oil seepage around the rod, slow movement and poor load performance all mean the seals are worn out.

Q: Can I use cheap alternative seal kits?
A: We don’t recommend it. Inferior seals wear fast and lead to frequent failures and higher maintenance costs.

Q: How to store spare sealing parts correctly?
A: Lay them flat in a cool dry area, and keep them away from sunlight, oil and sharp tools.

Q: Why replace the whole kit instead of single seals?
A: All seals wear at similar rates. Partial replacement will cause uneven sealing and new leaks soon.
