case. Insert the screws M5x30 through the opposite

the grip end reaches the holder case while passing
the throttle wire and the switch cords through the slot

square hole inside the holder case by slightly
rotating the drive shaft or the support washer on
the head case, and you can insert the drive shaft
into the holder case smoothly.
2) Be cautious not to allow the switch cords to be
pinched between the holder case and the grip end.

holes. Then tighten the screw M5x8 and the screws
M5x30. (Fig. 8)
