The arm of my mafiti MT-856 LED Desk Lamp has become loose and will not hold its angle. How can I tighten it?

Based on the manual for the mafiti MT-856 LED Desk Lamp, there are no specific user-serviceable instructions for tightening the internal tension of the arm. The manual advises to "gently unfold and adjust" the arm and warns against attempting to disassemble the lamp, as this will void the warranty.If the arm has become too loose to hold its position during normal use, please consider the following steps:Check for external screws: Inspect the hinge points (where the arm meets the base and where the lamp head meets the arm) for any small screws or caps. If there are visible screws, you may be able to gently tighten them with a precision screwdriver.Warranty Claim: Since the product includes a One Year Warranty covering manufacturing defects and issues arising from normal use, a loose arm that cannot hold its angle is likely covered. You should contact the retailer or mafiti's after-sales service team for a replacement or repair.Avoid Force: Do not apply excessive force to the arm, as the manual notes it is designed to rotate up to 225 degrees; forcing it beyond its limit may cause permanent damage.
