too quickly may cause the Lock Nut M4 (Black)

 [44] 

in the housing to come off and 

become idle. Turn the Truss Hd. Screw M4 (Black) 

[42]

 slowly so that the Lock Nut M4 (Black)

switch to check whether the two remaining battery level indicator lamps go on. Note that these 

indicator lamps go on when the indicator switch is pressed, and go off when the indicator switch is
