Sliding rails installment

Hi RotricsTeam @duzhipeng @Jeff_Rotrics @Jing @meifangjun

I have install my sliding rails last night, I want to mention the following in the instructions,

These bolts only use 1.5 to 2 turns of screw thread, this open it up to be stripped very easy, I have stripped one of my bolts without any force at all. Using a torque measuring tool and torque all the bolts the same, torque tool was set to its lowest setting.

Replacing the bolt with the spare from the packed did not help as the thread in the rails was stripped as well, because is both is aluminum.
