Peel back the bracket cover from the top and tighten the screw next to the one securing the cable clip (the red screw in the image) by 45 to 90 degrees clockwise.
Then check if the lever operates normally.
※Do not turn the screw more than 90 degrees.
For both the left and right levers, please tighten the screw clockwise.
If the issue does not improve even after tightening 90 degrees, return the screw to its original position and contact the store where you purchased the product.
