Can I adjust the closing speed of the door closer?

How do I maintain the door closer?

Regularly lubricate the pivot points and sliding parts with light oil. Check the arm screws for tightness. Avoid painting the closer body as solvents can damage seals.

Can the door closer be used on both left and right-handed doors?

What temperature range can the closer operate in?

The closer operates reliably between -20°C and +50°C. Extreme temperatures may affect hydraulic fluid viscosity; adjust speeds accordingly.
