rope slowly be retracted to the reel.
12.Pull the rope 2~3 times to confirm if it is fully
retracted. If it is not fully retracted, pull it out
halfway and while holding the reel with left
hand, hitch the rope to the reel notch and turn
additional 2~3 turns clockwise.
Excessive turns of reel cause overload on the coil
spring and may break it in short time.
As a guideline, retraction of the recoil spring is that
the reel can be turned 1~2 turns further with the
rope completely drawn out.
13.Reassemble the recoil case to the main body as
original.
