Installation Precautions

Diagonal step-by-step fixing: tighten the screws step-by-step in diagonal order to avoid uneven stress on the bottom shell resulting in gaps or deformation.

Stage-by-stage tightening: screw all the screws in gently first (without tightening), make sure the bottom shell is aligned and then gradually reinforce it.

Strength control: Screws can be tightened until they stop naturally, do not use excessive force to avoid slipping or damaging the threads.

Checking the closure: After installation, gently press around the bottom shell to make sure there is no warping or gap. If there is any abnormality, re-check the screws to make sure they are aligned.
