Installation of roof retainer
Insert the end of roof retainer into the
middle frame, and fix from the middle
frame side with small truss screw 5x10x10.
Step1
If the screw of installing the roof retainer is tighten
too much, the screw will run idle. Tightening torque
is about less than 1.5Nm (15kgfcm).
If the screw head leans when installing the roof
retainer, it will cause water leakage (water will enter
from the screw head clearance), so install it not to
make clearance.
